Ultimaker Cura 3.3.1 - April 25, 2018
Crash on Windows. Fixed an issue when the software crashes when installing to a drive other than C (Windows).
Crash with OctoPrint installed. Please go to the Plugin Browser and update to the latest version of the OctoPrint plugin after installing Ultimaker Cura 3.3.1.
Fixed missing profiles when updating to Ultimaker Cura 3.3.0.
Ultimaker Cura 3.3
Ultimaker Cura 3.3 - April 24th 2018
Profile for the Ultimaker S5. New printer profile for the Ultimaker S5, our latest 3D printer.
Profile for Tough PLA. New material profile for Tough PLA, a material that prints with the convenience of PLA but with toughness and impact strength similar to ABS.
Updated fonts. Default font changed to NotoSans to increase readability and consistency with Cura Connect.
Configuration/sync button. Configuration and synchronization button now available for Ultimaker network-connected printers to easily synchronize all possible available configurations in your Cura Connect group. The name of the group host is automatically pulled from the API, and network printers and local printers are separated in the list for clarity.
Plugin browser look and feel. The plugin browser has been updated with a better look and feel to bring it in line with other UI elements. The author name is clickable, which opens email for support. Plugins can now be uninstalled with an uninstall button.
Setting visibility preset. Presets guide you to find the most important settings incrementally. A small menu is located next to the search bar to easily access these new setting visibility presets. Contributed by fieldOfView.
Print/save hotkey. Send a print to the queue using Ctrl + P (Windows/Linux) or Cmd + P (Mac). If no printer is present on the network, it will save to file instead.
3D model assistant. Models sliced to print with ABS, PC, PP or CPE+ that have a larger footprint than 150 x 150 x 150 mm will notify the user with an icon and popup of how they can achieve the best possible print quality and reliability.
Refactored machine manager. Refactored machine manager resulted in fewer manager classes. Changing settings, materials, variants, and machines is now clearer. This results in an overall speed up when making changes.
Multiply models faster. Significant speed increase when multiplying models.
Show tooltip for unavailable profile. Tooltips have been added to incompatible settings, to give explanations why they are incompatible.
Empty material slots Ultimaker 3. When a material is not loaded in the Ultimaker 3, it is now displayed as ‘Empty’ rather than ‘Unknown’.
Send over network confirmation. When a print job is sent to a networked printer, a popup will confirm the job was sent, with a button to redirect the user to the monitor in Cura Connect.
Post-processing scripts. Fixed an issue where post-processing scripts could be lost between sessions. Post-processing scripts are now persistent between sessions.
Automatic slicing off by default. For a better user experience, the auto-slice functionality is now disabled by default.
Slicing engine optimizations
Single extrusion mode. Disable an extruder on a dual extrusion printer, so you are not limited by the other extruder’s parameters. To disable an extruder, right-click it in the right panel, and select ‘Disable extruder’ to disable it. Re-enable by right-clicking and selecting ‘enable extruder’. Printing profiles are optimized for the active extruder, as well as global settings, such as build plate temperature, to achieve better print quality. Using single extrusion mode also makes the ‘print one at a time’ feature available for the Ultimaker 3 and Ultimaker S5.
New UFP extension. UFP (Ultimaker format package) is a new file extension that contains compressed gcode and a preview thumbnail. Using this extension enables a model preview (similar to the solid view) on the Ultimaker S5 touchscreen and in Cura Connect.
Compressed gcode. Gcode saved from Ultimaker Cura using the Ultimaker 3 profile is compressed (using gzip) to save space on printers.
Circular prime tower. Prime towers are now circular, resulting in a less jerky print head action, a more robust structure, better layer adhesion, and better build plate adhesion compared to square prime towers, reducing the chance of prime tower failure mid-print.
Connected infill lines. Grid and triangular infill patterns now have connected lines for a more constant flow, better model rigidity, and reduced impact on the quality of the outer wall.
Support blocker. Generate a cube mesh to prevent support material generation in specific areas of a model. Each cube can be scaled, rotated, and moved with the standard adjustment tools to fit your requirements. When the support blocker tool is selected, click in the area you want to block support to generate a mesh. If it is positioned by accident, click it again to remove it. Contributed by fieldOfView.
Real bridging. New experimental feature that detects bridges, adjusting the print speed, slow and fan speed to enhance print quality on bridging parts. Contributed by smartavionics.
Updated CuraEngine executable. The CuraEngine executable now contains a dedicated icon, author information and a license. Contributed by thopiekar.
Use RapidJSON and ClipperLib from system libraries. Application updated to use verified copies of libraries, reducing maintenance time keeping them up to date (the operating system is now responsible), as well as reducing the amount of code shipped (as necessary code is already on the user’s system).
Print behaviour enhancements
Initial layer flow. New setting in the ‘material’ category where the initial layer flow can be adjusted.
Initial travel move retraction. Retraction has been added to the initial travel move, reducing the chance of prime blobs getting dragged into parts before brim/skirts are printed. Contributed by smartavionics.
Unnecessary retractions in spiralize. Removes retractions on layer change in spiralize mode, improving model quality. Contributed by smartavionics.
Faster travel paths. Until now, the path order optimizer worked on the basis that the shortest possible route could be taken from any one point to another. When combing is used, any route may longer, due to the need to route around obstacles. Now, it can use the combed distances to give more consistent results. Contributed by smartavionics.
New plugins. Three new plugins have been added to Ultimaker Cura; Scalable extra prime, Print temperature offset, and Enclosure fan. Contributed by Pheneeny.
Pre-heat extruders. This new feature allows to preheat the extruders in the printer monitor. Contributed by fieldOfView.
Renamed TweakAtZ to ‘ChangeAtZ’. This script has been renamed to be more consistent with other scripts.
Import XML material profile checks. XML material profile files are now checked before import in Ultimaker Cura to avoid potential issues. Contributed by fieldOfView.
Slice engine crash default temperature 0. Fixed an issue where the slicing engine could crash when slicing with a material at 0°C.
Network printer reconnect. Fixed an issue where the user could not connect to the printer after losing connection.
Pause at height ‘redo layers’ broken. Fixed an issue where setting ‘pause at height redo layers’ to 1 or more would cause failed prints.
Reset icon fix. Fixed an issue where manually reverting a default print profile value instead of using the reset button would cause the reset icon to remain.
Infill density for all extruders. The infill density in the recommended mode now applies to all extruders instead of extruder 1.
Polypropylene 0.25 mm print profile. Fixed the maximum number of allowed extrusions for all 0.25mm Polypropylene profile prints.
SolidWorks plugin. Replaced comtypes module with win32com to fix issues.
Font rendering issues. Fixed font rendering issues on Mac OSX.
Slice engine avoids broken wall segments. Fixed an issue where narrow walls created broken line segments by testing for such situations and using slightly narrow lines in those cases.
FABtotum TPU profiles. Added third-party material profiles for TPU. Contributed by krios-fabteam.
Dagoma profiles. Updated printer profiles contributed by dagoma3d.
uBuild profile. Updated printer profiles contributed by uBuild-3D.
Cartesio printer updates. Updated profiles contributed by maukcc.
Printrbot Simple Maker's Kit 1405. Profiles contributed by timur-tabi.
Added SeeMeCNC. Profiles contributed by pouncingiguana.
Velleman Vertex. Updated printer and quality profiles contributed by velbn.

Ultimaker Cura 3.2.1 - February 14th, 2018
MacOS fonts. Fixed a font rendering issue in MacOS.
Translations. Minor improvements to supported translations.
Fixed startup issues. Fixed an issue where Ultimaker Cura 3.2 would not start properly for some users.
Ultimaker Cura 3.2
Ultimaker Cura 3.2 - February 6th, 2018
New printing features
Tree support. Experimental tree-like support structure that uses ‘branches’ to support prints. Branches ‘grow’ and multiply towards towards the model, with fewer contact points than alternative support methods. This results in better surface finishes for organic-shaped prints, as well as reduced print time and material use compared to alternative support methods.
Adaptive layers. Prints with a variable layer thickness which adapts to the angle of the model’s surfaces. The algorithm assigns a narrower layer height to sloped surfaces, and a wider layer height to vertical surfaces. The result is high-quality surface finishes with a marginally increased print time. This setting can be found under the experimental category.
Faster startup. Printer definitions are now loaded when adding a printer, instead of loading all available printers on startup.
Backface culling in layer view. Doubled frame rate by only rendering visible surfaces of the model in the layer view, instead of rendering the entire model. Good for lower spec GPUs as it is less resource-intensive.
Multi build plate. Experimental feature that creates separate build plates with shared settings in a single session, eliminating the need to clear the build plate multiple times. Multiple build plates can be sliced and sent to a printer or printer group in Cura Connect. This feature must be enabled manually in the preferences ‘general’ tab. Currently it is restricted to one machine type, and all build plates must share the same settings.
Improved mesh type selection. New button in the left toolbar to edit per model settings, giving the user more control over where to place support. Objects can be used as meshes, with a drop down list where ‘Print as support’, ‘Don't overlap support with other models’, ‘Modify settings for overlap with other models’, or ‘Modify settings for infill of other models’ can be specified. Contributed by fieldOfView.
View optimization. Quick camera controls introduced in version 3.1 have been revised to create more accurate isometric, top, front, left, and right views.
Updated sidebar to QtQuick 2.0. Application framework updated to increase speed, achieve a better width and style fit, and gives users dropdown menus that are styled to fit the enabled Ultimaker Cura theme, instead of the operating system’s theme.
Hide sidebar. The sidebar can now be hidden/shown by selecting View > Expand/Collapse Sidebar, or with the hotkey CMD + E (Mac) or CTRL + E (PC and Linux). This is to give greater visibility for wider build plates, or build plates on small screens.
Disable ‘Send slice information’. A shortcut to disable ‘Send slice information’ has been added to the first launch to make it easier for privacy-conscious users to keep slice information private. Clicking the disable button will take the user to the preferences, where they can edit preferences accordingly.
Signed binaries (Windows). For security-conscious users, the Windows installer and Windows binaries have been digitally signed to prevent “Unknown application” warnings and virus scanner false-positives.
Start/end gcode script per extruder. Variables from both extruders in the start and end gcode snippets can now be accessed and edited, creating uniformity between profiles in different slicing environments. Contributed by fieldOfView.
OctoPrint plugin added to plugin browser. This plugin has moved to the plugin browser. This plugin enables printers managed with OctoPrint to print via Ultimaker Cura interface (version 3.2 or later).
Mirror tool and Center model. Fixed a bug where the mirror tool and center model options when used together would reset the model transformations. Transformations now stay as intended, even when models are centered.
User config on remote drive. Updated config file path to fix crashes caused by user config files that are located on remote drives. A typical case: when logging into a school system which loads your personal files and settings, Ultimaker Cura now correctly loads your config folder.
Updated Arduino drivers. Updated Arduino drivers to fix triggering errors during OTA updates in shared environments. This also fixes an issue when upgrading the firmware of the Ultimaker Original.
Auto-arrange all models. Fixed an issue where arranging small models would fail, due to conflict with small model files combined with the “Ensure models are kept apart” option.
Ultimaker Cura 3.1
Ultimaker Cura 3.1 - December 5, 2017
Profile added for 0.25 mm print core. New print core profile added for 0.25 mm print core. This new print core has an extra fine nozzle width, which gives prints high definition and increased surface quality.
Profile added for Breakaway material. New material profile added for Breakaway material, a dry post processing support material, which can be used for models with flat surface area overhangs.
Faster profile switching speed. Duplicating and removing a profile could take Ultimaker Cura quite some time, it now happens instantly.
Faster printer selection. Removing a printer from the library is now instant. No more unresponsive screens.
Faster processing speed. A 5 - 10 % speed increase when calculating normals, loading models, and slicing.
Quick camera controls. New buttons have been added to the interface that can quickly reposition the camera view of the build plate.
Lock model on platform. The move tool has a new option to lock a selected model to the platform. Once locked, it can not be moved in X, Y and Z directions.
Layer view. The existing Layer view has been updated to include a virtual print head that simulates the printing strategy. This can be used to see the printing order of infill and walls, and if line ordering affects overhangs.
Feedrate visualization. Feedrate visualization has been added to the Layer view. Speeds have corresponding colors, ranging from red to blue. Fast speeds (up to 250 mm/s) are represented by red (e.g. print head travels). Slower speeds (20 mm/s) are shown in blue, (e.g. the first layer of a print). Using this gives the user an idea of the print speeds per model part, allowing for better control over prints and more informed fabrication.
Jogging. Jogging allows the printhead to be moved with on-screen controls. The Ultimaker 2+ and other RepRap printers can now be fully controlled from Ultimaker Cura when connected through USB. Each axis can be jogged in 0.1, 1, 10 and 100 mm increments.
Large model loading. Loading large/detailed models and slicing them on a high resolution could affect the performance of Ultimaker Cura in previous releases. A new feature has been added which unloads the layer view when switching to solid mode, speeding Ultimaker Cura back up without losing your G-code/layer view information.
Scripts folder. A scripts folder is now available in the Ultimaker Cura configuration folder. This folder can be loaded with post processing plugins scripts, which will automatically show in Ultimaker Cura. Contributed by fieldOfView.
HP 3D Scan compatibility. HP 3D Scan Version 5.3.0 results can be directly exported to Ultimaker Cura application version 3.0.4 and later
Optimized workflow for crash reporting. Crash reports are automatically generated and allow the user, in case of a crash, to easily send their report with a description to developers.
New slicing features
Floating models enabled. In previous releases, models were dropped to the build plate when support was disabled. Models now float when the setting is enabled (even if creates an impossible-to-print situation). This can be used to stack separate models on top of each other.
Slicing tolerance. A new setting that affects the intersect point to influence the dimensional accuracy for diagonal surfaces. The user can select the behaviour: ‘Inclusive’ makes gaps narrower, ‘Exclusive’ makes gaps wider, and ‘Middle’ is previous option, and also the fastest to process. When using ‘Middle’, the first layer will be taller by half of it’s height to compensate for the added half layer. This can be used to create better tolerances for test fit parts. Contributed by BagelOrb.
Optimized zig zag patterns. Zig zag patterns now print more consistently. Lines now have a 5 micron tolerance in which they are printed any way, resulting in longer connected lines. Contributed by smartavionics.
Aligned z-seam inner wall moves. Inner wall travel moves are aligned with the z-seam. This reduces the number of travel moves and reduces the chance of more unwanted seams.
Relative positioning of infill patterns. Infill patterns are now positioned relative to the center of loaded models. Whenever you load the model, the infill is positioned the same. An offset can be applied to control the infill more precisely and adjust it to preference or strength. Contributed by smartavionics.
Line resolution. Enables the user to specify the minimum allowed distance value between two points in G-code to create lower or higher resolution polygons.
Custom mode changes. If profile settings have been modified in recommended mode under custom mode, a reset icon will appear to notify the user. Click the icon to show the changes that have been made, and revert back to the default profile settings.
- Fix for layer numbers being displayed incorrectly when switching between solid and layer mode
- Fix for Cura Engine crashes during slicing if Optimize Wall Printing Order setting was enabled
- Fix for uninstalling previous versions of Cura on Windows platforms
- Fix for displaying visible settings
- Fix for importing legacy .ini files
- Prevent skipping user agreement dialog by pressing escape
Ultimaker Cura 3.0
Ultimaker Cura 3.0 - October 17, 2017
Faster start-up. Start-up speed has been cut in half compared to the previous version.
New color scheme. Color scheme has been updated.
Updated UI design. The Ultimaker Cura logo has moved from the bottom to the top of the interface. Print status icons have been updated and repositioned.
Redesigned splash screen. A new splash screen on Ultimaker Cura startup has been added.
Top navigation bar improvements. The width of tab functionality changes accordingly to the word space (multilingual).
Print quality slider. A slider can now be used to control the quality profile in recommended mode.
Infill slider. Model infill can now be changed using a slider in recommended mode.
Changed layer view. Layer view icon, panel and slider have moved to top-right of interface.
Rasterized build plate. The build plate now shows graduations of 10 mm and 1 mm for easy model positioning.
Changed row of extruder buttons. Extruder tabs have become buttons and icons have been updated.
Add an "Export to Ultimaker Cura" button in SolidWorks. SolidWorks plugin can now be installed using an automatic installer.
Siemens NX macro. When a user updates models in Siemens NX and clicks the button, the updated models replace the models opened in Ultimaker Cura.
Skin removal width. Remove thin strips of skin from a model to prevent print head zigzagging, in turn preventing vibrations.
Skin expand distance. Cutting away skins on steep overhangs makes prints less sturdy. By expanding skins with the thickness of walls, features will be better supported. In addition, features such as towers on top of infill will be stronger.
Extra skin wall count. Printing extra skin directly on top of infill can lead to gaps, curling and pillowing. This is reduced by printing a wall around the skin first, and also improves the printing speed.
Minimum extrusion for skin. Will prevent filling small gaps that are probably filled already, resulting in less strings, better top details and faster prints.
PVA retractions. PVA (switch) retraction length is increased, minimum travel distance for retraction is decreased and max count is slightly increased, this reduces stringing by a lot at the cost of slightly increased print time.
Z seam options. Gives the user control over where to place the seam - hide it in convex corners or in easy to remove locations such as concave corners. Don’t let corner angles influence the seam position.
Quarter cubic infill. Similar to tetrahedral (octet) infill, but half of the lines are shifted half of the period up. This pattern sacrifices some rigidity of octet infill for greater toughness.
Cross infill. A fractal pattern infill that requires fewer retractions than other infill types. This is useful for flexible materials as it causes less material elongation. The internal structure given by this infill also assists flexible models having more resistance, while retaining ‘soft’ properties in all directions.
Layer start negative position. Layer start X/Y values can be less than 0 when the machine center is zero.
PostProcessing stretch script. This new script performs "post stretch" algorithm to fix the problem of insufficient inner and outer diameters. Thanks to electrocbd for contributing.
Ironing speed settings. Ironing speed settings have been moved to experimental category.
Doodle3D plugin. Update Doodle3D plugin to connect with printers. Thanks to mith for contributing.
Several bugs have been fixed related to:
- Customized profiles are not sent when connecting to a printer
- Sync z-hop with layer changes, thanks to smartavionics for contributing
- Memory leaks on MacOS
- Printer name not loaded when project file is opened
- Doodle3D Wifi box was selected by default on non-Ultimaker 3 printers
Cura 2.7 - August 30, 2017
Relative Z seam. Make the Z seam relative to the bounding box of the model, so that the seam stays at the same location no matter what the position of the object is. Thanks to smartavionics for contributing.
Top surface skin. Specify print settings of the top-most layers separately in order to decrease print duration and achieve higher quality top surfaces. Thanks to BagelOrb for contributing.
First layer line width. A multiplier setting for the line width of the first layer of a print. Multiplying line width gives less lines but with greater width, which improves build plate adhesion. Thanks to 14bitVoid for contributing.
Set horizontal expansion on initial layer. Adds functionality to change horizontal expansion on the initial layer to compensate for the “elephant’s foot” effect. Thanks to fieldOfView for contributing.
Skin lines corner efficiency. Selects a better corner to start printing skin at to reduce the number of times the skin needs to be split to avoid causing a visible seam.
Ironing (a.k.a. Neosanding). Finishes prints by pushing the heated nozzle over top surfaces with reduced extrusion. Thanks to Neotko for contributing.
Plugins moved to server. All current plugins shipped with Cura are placed on a server. This allows the user to view, download and install all available plugins from within the plugin manager.
Standby and resume temperature. Turns off the extruder when printing with extended pauses to avoid filament burning and nozzle clogging. Thanks to JPFrancoia for contributing.
Easy plugin installation. Implemented a plugin browser to download and discover new plugins. This also includes a file association for plugins (using extension “.curaplugin”). Plugin files are contained in a .zip file which contains all necessary files. Plugins can be installed by dragging and dropping files onto the Cura virtual build plate.
Prime tower purge. In order to prevent under extrusion when printing a prime tower, and to prevent a prime tower failing half way through a job, a feature has been added to wipe off oozed/purged material in the middle of a hollow prime tower before starting to print the next layer of it. The amount of material to purge can be specified in the “Prime Tower Purge Volume” setting.
Extruder per feature. Assign an extruder to print a particular feature, including infill, wall, outer wall, inner wall and skin.
Print thin walls. Print object walls up to two times smaller than the nozzle size. Thanks to BagelOrb for contributing.
Gradual support infill. Supports print with gradually increasing density in order to reduce the print time and amount of material used. This is useful when printing with more expensive materials such as PVA.
Support infill layer thickness. Users are able to configure “Support infill layer thickness” for thicker support layers. This uses less material, while improving overhang quality.
Reduced skin splitting. Selects a varying corner to start printing skin at in order to reduce the number of times the skin needs to be split. This prevents any unsightly visible seams in the model. Thanks to smartavionics for the contribution.
Cura data collection. Collects slice data from Cura database so that it can be processed by a business intelligence tool.
Add optional extruder type. Includes the option to override the default extruder that is designated to print infill/skin/walls if necessary.
New UI features
Dark theme. A dark theme in Cura. Ideal for low light environments. Thanks to fieldOfView and rudowinger for contributing.
Top navigation bar. “Prepare” and “Print” have moved from the right side of the top navigation bar to the left side.
Increased scroll speed in the settings list. The side bar scroll speed is now three times faster when scrolling through settings. Thanks to tsaaristo for contributing.
New hotkeys. Implemented keyboard shortcuts for "move" (q), "scale" (a), and "rotate" (z).
Dialogs for high DPI screens. Fixes some large dialog boxes on high DPI screens and aligns infill icons to the select boxes. If the text is too big, it will overlap but the icons will remain aligned.
Theme inheritance. Themes no longer have to be complete; they can simply inherit features from a default theme. Thanks to fieldOfView for contributing.
Interface elements upgraded to PyQt 5.8. When starting Cura, screen is rendered using PyQt 5.8, so the interface can load elements for extruder per feature.
Dual extrusion forbidden zones. In older versions of Cura there are “forbidden zones” on the build plate that do not correspond to print head position. This has now been fixed.
Zoom towards mouse cursor position. New option to zoom towards the mouse cursor position to reach specific parts of the build plate more easily. Thanks to nallath for contributing.
Import SolidWorks files as STL. Plugin that enables SolidWorks files to be imported into Cura directly, where they are automatically converted to .STL format. This plugin can be found in the plugin browser.
Cycle interfaces hotkey. Cycle through interfaces using the tab key. Thanks to fieldOfView for contributing.
Descriptive tooltips. Adds more descriptive tooltips to the setting fields in machine settings. Thanks to fieldOfView for contributing.
Polish now supported. Polish language support added, which can be selected in the preferences menu. Thanks to "Jaguś" Paweł Jagusiak and Andrzej "anraf1001" Rafalski for contributing.
Simplified Chinese now supported. New translations for simplified Chinese added. Thanks to jockeysoft for contributing.

- Stair step support buttom distance
Cura 2.5 - April 19, 2017
Please note: When upgrading Cura from an older version (Cura 2.4 or earlier), the configuration settings may be overwritten. Remember to back up your configuration folder before installing Cura 2.5.
- Improved speed. Users will notice significant speed improvements when changing printers, profiles, materials, and print cores, as well as opening and processing 3MF files.
- Multithreading. On computers with multiple cores (Windows or Linux operating systems only), Cura can now process multiple operations concurrently while slicing.
- Preheat the build plate. Users can set the connected Ultimaker 3 to preheat the build plate, which allows to reduce the downtime and speed up the workflow.
- Better layout for 3D layer view options. We’ve incorporated an improved layer view for computers that support OpenGL 4.1. For OpenGL 2.0 to 4.0, Cura will automatically switch to the old layer view.
- Disable automatic slicing. User can now disable auto-slicing.
- Auto-scale off by default.
- Print cost calculation. Cura 2.5 helps users calculate the cost of their prints by entering a cost per spool and the amount of materials per spool. Thanks to Aldo Hoeben for this feature.
- G-code reader. The g-code reader has been reintroduced, which means users can load g-code from a file and display it in a layer view. It is also possible to print saved g-code files, share, re-use them, and preview the printed object via the g-code viewer. Thanks to AlephObjects for adding this feature.
- Discard or Keep Changes popup. When users change printing profiles after customizing print settings, a popup appears with the option to transfer customizations to the new profile or discard modifications and continue with default settings. This dialog window is now more informative and helpful.
- New infill settings. The Expand Skins Into Infill setting allows users to specify if skin layers extend into areas of infill. This avoids the expansion of narrow areas of a skin next to walls that are not vertical. The Minimum Infill Area allows users to specify minimum areas of infill to be replaced with a skin. Top/Bottom Line Directions & Infill Line Directions settings let users control the directions used for most suitable patterns (e.g. line, zig zag etc.). Thanks to our community member Mark Burton for these features.
- Window overflow. Fixed an overflow on the General (Preferences) panel and the credits list on the About window on certain configurations (OS and screen dependent).
- “Center camera when the item is selected” is now set to ‘off’ by default.
- Removal of file extension. Now when users save a file or project without changing the file type, no file extension is added to the name.
- Ultimaker 3 Extended connectivity. When Ultimaker 3 Extended is selected, Cura will no longer allow users to connect to and print with Ultimaker 3 without a warning.
- Y and Z colors in the tool menu now correspond to the colors on the build plate.
- No collision areas. Fixed the no collision areas that were generated for some models when "keep models apart" was activated.
- Perimeter gaps are now filled.
- Cura 2.5 remembers the last opened file location after restart.
- The project name no longer changes after the project is opened.
- Slicing when error value is given (print core 2). When a support is printed with the Extruder 2 (PVA), some support settings triggered a slice when an error value is given. This has been fixed.
- Support Towers can now be disabled.

Cura 2.4 - February 21, 2017
- Project saving / opening. Cura 2.4 now lets you save your build plate configuration, which includes all your active machine’s meshes and settings too. Even more conveniently, when you reopen your project file, you’ll see that all build plate configurations and settings are exactly as you left them when you last saved the project.
- Search Settings. It’s now easy to search custom settings via the side panel.
- Editing start / end g-code. If you need to alter the start and end g-code settings for your single-extrusion machines, the new Cura 2.4 lets you do just that.
- Multiply object function. Right-click an object, and you can multiply it by a variable amount.
- Single-extrusion prints. Your Ultimaker 3 dual-extrusion printer now lets you do single-extrusion prints within a larger printable area.
- Streaming printer monitor view. You can follow the progress of your 3D print using the live streaming function.
- Impossible settings in error message. If slicing is blocked by settings with error values, a message will appear to clearly indicate the settings to be changed.
- Ultimaker 3 printing profiles. The new Ultimaker 3 printing profiles increase reliability and decrease print time. Initial and final printing temperature settings have been tuned for higher quality prints and reduced oozing during PLA-PLA, PLA-PVA and Nylon-PVA prints. This means printing a prime tower is now optional (except for CPE and ABS). The new Ultimaker 3 printing profiles ensure increased reliability and shorter print time.
- Initial layer printing temperature. The initial and final printing temperature settings have been fine-tuned for higher quality results.
- Material printing temperature. The material printing temperature (in the material profiles) is now the same as the printing temperature for the Normal Quality profile.
- Improved PLA/PVA layer adhesion. The PVA jerk and acceleration has been optimized to improve layer adhesion between PVA and PLA.
- Nylon – default build plate adhesion type. The default build plate adhesion type for Nylon prints has been changed from raft to brim.
- Support Interface Thickness. To reduce printing time, we’ve changed the Support Roof Thickness to 0.8mm, and slightly decreased the PVA support infill.
- Ultimaker 2+ PC prints. The raft settings for the 0.25mm and 0.4mm nozzles have been adjusted in the polycarbonate profiles.
- Hollow prime tower. Minimize material use without sacrificing stability by printing the prime tower hollow. Wiping the oozed material on the prime tower is now done from the inside, so the excess material is contained within the prime tower.
- Precooling / Prewarming. Printing now starts at a lower temperature, then swiftly increases to the normal printing temperature. Cooling also starts earlier than the last extrusion with that print core. This minimizes the material’s heat absorption decreases the amount of degradation of the PVA material, and reduces the risk of clogged nozzles.
- Remove Mesh Intersection. If required, you can now switch off resolving of overlapping meshes. Models can now overlap, which means you can mix colors on the build plate by placing meshes over one another and lowering their flow.
- Alternate Mesh Removal. For areas where two models overlap, you can now let each layer of the overlapping volume alternate (depending on which object the overlapping area of that layer belongs to). This boosts bonding between dual-color models, and results in better control of build plate color mixing.
- Hollow Object. If you want to, you can remove the infill from a mesh and treat internal cavities as overhangs, which creates better support in the model’s interior. This also reduces the amount of material required on the inside of your print.
- Fill Gaps Between Walls. Fill small gaps between consecutive walls to make thin areas dense rather than hollow – adding strength to your model.
- Cubic subdivision infill. This experimental new infill pattern works on a similar basis to cubic infill – but generates larger cubes further inside the mesh. It’s a great way to reduce material use and cut your print time, whilst maintaining structural integrity.
- Concentric 3D infill. This new infill pattern is similar to concentric infill, but touches the shell every X layers, creating better support for the top layers.
- Printing Temperature Initial Layer. You can now determine the nozzle temperature during the first layer.
- Build Plate Temperature Initial Layer. You can also determine the bed temperature during the first layer.
- Initial Fan speed. Select the fan speed for the first layer, for better print results.
- Retract at Layer Change. You can choose to retract each time the printer moves to the next layer.
- Outer Wall Wipe Distance. Wipes the nozzle after printing an outer wall.
- Set X-Y coordinate of Z seam. You can select where to place the Z seam.
- Start Layers with the Same Part. Start each layer with the part closest to a selected location.
- Turn off nozzle after last use. Switch off the nozzle after its last use, while the other nozzles are still in action.
- No build plate adhesion. If required, you can select not to print any build plate adhesion helper parts.
- Anti-overhang and support meshes. Use a mesh to specify a volume within which to classify nothing as overhang for support, or to specify a volume within which to print support.
- Delta printer support. This supports printers with elliptical build plates. Please note, we haven’t extensively tested this yet, and any feedback would be greatly appreciated.
- Applmage for Linux. The Linux distribution is now in Applmage format, which makes Cura easier to install.
- New Cura notification. You’ll now be notified when a new version of Cura becomes available.
- Category visibility. When searching in the setting visibility preferences, the setting category is always displayed.
- 3MF files. 3MF files are now saved and loaded correctly.
- Drag and load. Dragging a profile onto Cura now loads it automatically.
- View print core / materials. It’s easy to view which print cores and materials are currently in your Ultimaker 3, via the machine manager.
- Add heated bed upgrade. You can add the heated bed upgrade (and other things) from the machine manager.
- Print core / material under extruder tabs. These are now arranged under the extruder tabs.
- Saved printers / profiles. Cura automatically remembers all printers and profiles when you open it (just after closing it).
- Duplicate profiles. You can now duplicate all standard profiles.
- Layer view changes. Layer view uses less RAM.
- Quicker Support Enable setting changes. It’s far quicker to change the Support Enable setting values.
- Dependent setting changes. Changing one setting now updates all dependent settings more quickly.
- Slicing block. If there are any errors in your setting values, slicing is automatically blocked.
- Active tools, no more re-slice. Selecting a model with any active tool no longer causes a re-slice.
- Prime poop changes. The prime poop now features a separate area (which cannot be printed in).
- Adjusted Support Extruder setting. We’ve moved the Support Extruder setting near the support settings.
- Adjusted Build Plate Adhesion Extruder setting. The Build Plate Adhesion Extruder setting is now near the build plate adhesion settings.
- Z Hop setting location. Z hop settings have been moved to the Travel category.
- Inactive nozzle wiping. Inactive nozzle wiping on the prime tower has now been re-enabled.
- Support retraction removal. There are now no longer any unnecessary retractions in support.
- Reduced extruder switches. Each layer now has less extruder switches than the machine has extruders.
- No concentric infill for first infill perimeter. Concentric infill doesn’t generate the first infill perimeter next to the walls.
- Extruder priming for the first layer. Extruder priming now always happens on the first layer.
- Ultimaker 2 build plate speed. Ultimaker 2’s build plate raise is now the proper speed again.
- Ultimaker 2 material change. Ultimaker 2 can once again change material while printing is paused.
Note: When upgrading Cura, the configuration settings might be irreversibly changed. We are working on the solution. Meanwhile, to ensure you don’t lose any customized settings, we recommend to back up your configuration folder before installing the latest version of Cura.
