We never stop working to provide you with the best software possible for your 3D printing needs. We’ve been creating even more improvements to Cura, and with the help of our customers and community, we’ve created the most seamless user experience yet. Check out what’s new in Cura 2.4 Beta!
Project saving & opening. Save your build plate configuration including your active machine’s meshes and settings before you close. When you reopen the project file, the build plate configuration and settings will be exactly as last saved.
Search Settings. Search custom settings directly from the side panel. Now you can easily locate the setting you need to tweak.
Edit start and end g-code. For single-extrusion machines, you can now alter both start and end code g-code settings.
Multiply object function. You can now multiply an object by a variable amount instead of duplicating multiple times. Just right click on the object.
Ultimaker 3 single-extrusion prints. Dual-extrusion printers now allow for single-extrusion prints in a larger print area.
Streaming printer monitor view. Ultimaker 3’s camera views now show a live stream instead of snapshots.
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 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 and final printing temperature for all printers. The initial and final printing temperature settings have been fine-tuned for higher quality results.
Material printing temperature. The printing temperature of materials in the material profiles is now the same as the printing temperature in 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. The Support Roof Thickness is now 0.8 mm and PVA support infill has been slightly decreased to speed the printing time.
Ultimaker 2+ PC prints. In the polycarbonate profiles, the raft settings for the 0.25 mm and 0.4 mm nozzles have been adjusted to lessen warping.
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 and 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. Turn off resolving overlapping meshes. Models can now overlap. This means you can perform color mixing by placing meshes over each other and lowering their flow.
Alternate Mesh Removal. For areas where two models overlap you can now alternate the overlapping layer. This improves the bonding between dual-color models and allows for more controlled color mixing.
Hollow Object. This experimental setting reduces the amount of material needed on the inside of the print. Just remove the infill from a mesh and treat internal cavities as overhangs, to support the model’s interior.
Fill Gaps Between Walls. This feature makes thin pieces stronger. Fill up small gaps between consecutive walls, by making thin pieces in your model dense, rather than hollow. This feature makes the thin pieces stronger.
Cubic subdivision infill. This experimental infill pattern is like cubic infill, but generates bigger cubes farther inside the mesh. This greatly reduces print time and material use, while 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.
More new features
The following features have also been added:
- Printing Temperature Initial Layer: Nozzle temperature to be used during the first layer.
- Build Plate Temperature Initial Layer: Bed temperature to be used during the first layer.
- Initial Fan Speed: Fan speed to be used during the first layer.
- Retract at Layer Change: Retract each time the printer progresses to the next layer.
- Outer Wall Wipe Distance: Wipe the nozzle after printing the outer wall.
- Set X-Y coordinate of z-seam: Select where to place the Z seam.
- Start Layers with the Same Part: Start each layer with the part closest to a given location.
- Turn off nozzle after last use: Turn off the nozzle after its last use, while other nozzles are still in use.
- Option for no build plate adhesion: Select to skip printing 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 specify a volume within which to print support.
- Delta printer support: Cura 2.4 Beta adds support of printers with elliptical build plates. Please note that this feature has not been extensively tested and we look forward to your feedback.
- AppImage for Linux: Cura is now easier to install thanks to the Linux distribution in an AppImage format.
Bug fixes and minor changes
Like all releases, this one fixes a few bugs that were identified and also makes some minor changes.
- Communication improvements. The user experienced has been improved. You are now notified when a new version of Cura is available. You can now view which print cores and materials are currently in your Ultimaker 3, via the machine manager. When searching in the setting visibility preferences, the category for each setting is always displayed. Print core and material is now arranged under extruder tabs.
- Setting changes. It’s now quicker to change the value of the Support Enable setting. Changing a setting updates all dependent settings more quickly. Having errors in your setting values now always blocks slicing. Selecting a model with any active tool no longer causes a reslice. Support Extruder setting is now near the support settings. Build Plate Adhesion Extruder setting is now near the build plate adhesion settings. Z hop settings have been moved to the Travel category.
- Files and profiles. 3MF files are now saved and loaded correctly. Dragging a profile onto Cura now loads it automatically. Cura now remembers all printers and profiles when you open just after closing it. You can now duplicate the standard profiles. Layer view now doesn’t use as much RAM. You can now add the heated bed upgrade etc. from the machine manager.
- Print fixes and changes. Inactive nozzle wiping on the prime tower is re-enabled. There are no more unnecessary retractions in support. Each layer now has fewer extruder switches than the machine has extruders. Concentric infill doesn’t generate the first infill perimeter next to the walls. Extruder priming now always happens on the first layer.
- Updates for Ultimaker 2 users. Cura 2.4 Beta fixes an issue with the speed at which the build plate of the Ultimaker 2 is raised. Plus, it re-enables the material change when the Ultimaker 2 is paused.
