What’s new in Ultimaker Cura 3.5?

  • Hotkeys. Quickly toggle through model manipulation tools using hotkeys for a better user experience
  • Monitor page. We’ve remodeled Ultimaker Cura’s monitor page for better consistency with Cura Connect
  • 3MF project files. All Ultimaker Cura projects now save in a 3MF format, for better compatibility with other 3D software

Read on to see highlighted features in this version.

User experience

File menu. We’ve changed the behavior of the file menu. ‘Save’ now saves projects, and ‘Export’ saves models as another file type.

New tool hotkeys. Hotkeys have been assigned for quick toggling between the translate (T), scale (S), rotate (R), and mirror (M) tools.

3MF project files. We’ve retired the ‘.curaproject’ extension. Project files now use a 3MF extension, for better compatibility between other 3D software applications.

Open recent projects. Project files can now be found in the ‘Open Recent’ menu, alongside regular model files.

Open project files directly from the ‘Open Recent’ file menu

Materials preferences. Materials can now be set as a favorites, so they can be quickly and easily accessed in the material selection panel at the top-right of the screen.

Monitor page. The monitor page of Ultimaker Cura has been remodeled for better consistency with the Cura Connect ‘Print jobs’ interface. This means less switching between interfaces, and more control from within Ultimaker Cura.

Monitor UI
The UI of the monitor page closely matches the UI of Cura Connect

Save project. Saving a project no longer triggers a project to reslice — ideal when slicing takes a long time!

Slicing enhancements

Improved overhang wall processing. Overhang walls are automatically detected and printed with varying speed, and perimeters will not start on an overhanging wall. Printing overhang walls at a different speed gives higher-quality and more reliable results.

Overhang
Use the ‘feedrate color scheme’, to represent the print speed in different areas of the model. Overhang areas on this bridge print with different speeds than other areas, for better results

Minimum polygon circumference. Polygons in sliced layers that have a circumference smaller than the setting value will be filtered out. Lower values lead to higher resolution meshes at the cost of increased slicing time. This setting is ideal for small scale prints with a lot of detail, or for SLA printers.

Initial layer support line distance. This setting enables the user to reduce or increase the density of the support initial layer in order to reduce or increase adhesion to the build plate and the overall strength.

Extra infill wall line count. This adds extra walls around the infill area, which can help to support top/bottom skin lines so that they sag less. This means you need fewer top/bottom skin layers for the same quality, at the cost of some extra material.

Prime tower reliability. Printing with two materials that don’t adhere well could cause the prime tower to fail during a print, so we have repurposed the prime tower to create a shell of one material and use it as a purge bin for a second material, giving it significantly more strength and reliability than before.

Improved prime tower
Prime towers now use a shell of one material, to create a purge bin for the other material. This makes the prime tower more reliable

Connected infill polygons. Similar to connecting infill lines, it is now possible to connect the cross and cross 3D infill polygons of a layer together. This feature can be combined with ‘Multiply Infill’ and ‘Extra Infill Walls’ to ensure a continuous extrusion pattern based on any infill pattern.

Fan speed override. A new setting has been added to modify the fan speed of bridged areas, under ‘Support settings > Fan Speed Override’. This will only work when support is enabled.

Minimum wall flow. A new setting has been added to the ‘Shell’ category to define a minimum flow for thin printed walls.

Support infill line direction. Support infill lines can now be rotated to increase the supporting capabilities and reduce artifacts on the model. This setting rotates existing patterns, like triangle support infill.

Multiply infill. Creates multiple infill lines on the same pattern, for stiffer infill.

New plugins

Cura settings guide. A detailed, searchable index of Cura settings, complete with images for reference.

Custom support. A tool similar to the support blocker that adds cubes of support to the model manually by clicking parts of it.

Quickly toggle autoslicing. Adds a toggle button to the progress bar to quickly enable/disable autoslicing.

Version in title bar. Display the version number in the application title bar for quick reference.

Third-party printers

New profiles have been added for TiZYX, Winbo, Tevo Tornado, Creality CR-10S, and Wanhao Duplicator. Profiles have been updated for Deltacomb and Dacoma.

Bug fixes

For better stability and performance, we have fixed a variety of bugs in this release. This includes removing excess M109 commands in GCODE and unnecessary travel movements, improving extra skin wall count and the order of printed models, and many more.
