UltiMaker Cura 5.3.0-beta.1 Pre-release

Pre-release

This release does not yet contain the new tree support implementation by @ThomasRahm. You can download a special Cura version for that here.

Interlocking Structure Generation
This new setting enables you to interlock multiple materials together, even if those materials are not compatible, contributed by @BagelOrb. Try it for yourself with this test model.

Brim per Material
A brim can now be printed with multiple materials in the same model, contributed by @BagelOrb

Updated Recommended Print Settings Menu
The number of settings available in the recommended has expanded. The redesign will make it easier to use intent profiles or save custom profiles.

Other new features and improvements.

Improved the Zseam behavior so Hide Seam is generated less randomly.
Fixed the order in which concentric top/bottom patterns are printed.
Replaced mentions of Ultimaker by UltiMaker to correctly reflect the merger.
Updated Load Project window with a new design.
Added tooling to automatically generate translation files to reduce the chance of human error.
Added quality type to slice meta-data so it can be displayed in the Ultimaker Digital Factory.

5.2.2

62fa625

UltiMaker Cura 5.2.2

Introducing the UltiMaker S7
- Included support for the new UltiMaker S7

Bug fixes:

Allow UltiMaker S7 printers to receive Material Profiles

Printer definitions, profiles and materials:

Improved Initial Layer settings for UltiMaker S7, S5, and S3 printers
Disabled Support Towers for UltiMaker S7, S5, and S3 printers
Cleaned up material profiles, by removing duplicate setting segments, and unused elements
Updated preferred quality type for all UltiMaker 3D printers

Known critical issues:

Support is sometimes missing in detailed parts, where previous releases supported them properly (still). (Will probably not be fixed in stable. This is currently slated for 5.3)
Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances. (Will probably not be fixed in stable.)
If you are looking for an AppImage for your Linux OS we recommend using linux.AppImage. If you run into issues with launching your AppImage, we have linux-modern.AppImage ready as an alternative.

Does Cura (not) work on your OS (version)? See this article for clarification.

5.3.0-alpha+xmas

46e4ac7

UltiMaker Cura 5.3.0-alpha+xmas Pre-release

Pre-release

New tree support implementation by @ThomasRahm
This tree support uses significantly less filament, reduces printing time, and is easier to remove than our current tree supports. A number of new settings can now be applied to your tree supports, including support blocker, per-model settings, and support horizontal expansion.

The newly introduced settings are:

Tree Support Preferred Branch Angle
Tree Support Maximum Branch Angle
Tree Support Diameter Increase to Model
Tree Support Minimum Height To Model
Tree Support Initial Layer Diameter
Support Interface Priority
Tree Support Limit Branch Reach
Tree Support Optimal Branch Range
Tree Support Rest Preference

Known Issues

Engine crashes– Often if you try to rotate the model or move it away from the center it's resolved. If this doesn't resolve your issue we would love to get your project file to learn what's wrong
Floating islands inside of support
Adaptive Layerheights are not always working correctly
Support Interface is not always working correctly
Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances.
If you are looking for an AppImage for your Linux OS we recommend using linux.AppImage. If you run into issues with launching your AppImage, we have linux-modern.AppImage ready as an alternative.
Windows users might get a "Microsoft Defender SmartScreen preventing the installation of an unrecognized app". You can verify if the publisher "NL, Utrecht, UltiMaker, UltiMaker" and click Run anyway by clicking on the More info text.

Does Cura (not) work on your OS (version)? See this article for clarification.

📣 We would love to hear your feedback here

5.1.1

6aa68dd

Ultimaker Cura 5.1.1

New features:

Added support for the updated mainbord revisions of Ultimaker S3 and Ultimaker S5

MacOS 10.15 is no longer supported. Technically this means Ultimaker will stop testing and developing for such operating systems. However, even though it is no longer supported, there is still a high likelihood the application keeps functioning.

5.1.0

3dad5d5

Ultimaker Cura 5.1.0

For an overview of the new features in Cura 5.1, please watch our video.

Improved toolpath simplification algorithm
The algorithm that reduces the resolution of the print has been rewritten, providing a more constant resolution to allow for greater precision without causing buffer underruns.

Added option to alternate wall direction
A new setting causes the direction of printing walls to alternate between layers and adjacent walls, which reduces warping in the print.

Adjusted combing boundaries to reduce scarring
Travel moves through the inside of the models are adjusted so that they should keep more distance from the model where possible, yet allowing travels through narrow parts without retractions.

Reduced acceleration and jerk commands for travel moves
We added the option to disable acceleration and jerk commands for travel moves. If disabled, they will take on the acceleration of the printed part of its destination. This greatly reduces file size and buffer underruns.

Project files know which packages they require
Newly created project files will now store which packages they require from the Ultimaker Marketplace. If a project needs a material from there, the user will be prompted to download it.

Other new features and improvements:

The interface to select the printing profile in Recommended Mode has been redesigned.
Implemented multi-threaded slicing for MacOS, to bring it in line with other operating systems, contributed by @Piezoid.
Cura now links toolpaths to project files in the Digital Factory.
Improved performance of loading STL files on Linux.
Packages from the Marketplace can now contain intent profiles.
The application now makes heavy use of Conan to make it easier and faster to build releases of Cura.
Start and end g-code can now refer to the currently active profile with replacement keys.
To provide proper compatibility with both older and newer Linux distribution, this release contains two Linux builds.

Bug fixes:

Fix resetting configuration if it gets corrupt.
Monotonic ordering now works again for top surfaces.
Fix a bug where Remove Raft Inside Corners didn't always remove all corners.
Fix the position of the toolbar if the toolbar is too tall to fit.
Intents in the Recommended Mode now show a description again.
Remove Inside Corners and Raft Base Wall Count can now be changed per extruder, though they will affect the entire print.
Fix opening STL files with special characters in their header.
Fix crash at start-up on newer Linux distributions.
Fix priming when printing a raft with a different extruder for some of its layers.
Fix a case where the inner wall ends up protruding through the outside of the model.
Improve some details on dark mode colouring.
Fix an error sometimes occurring when uninstalling plug-ins.
Fix a rendering issue with pop-up dialogues on MacOS.
Fix Discard or Keep Changes dialog showing an outdated setting value.
Horizontal Scaling Shrinkage Compensation no longer adjusts the size of the build volume, allowing the full size of the build plate to be used.
Fixed overextrusion when using gradual infill with thin strips of infill.
Fix opening STL files with special characters in their file header.
Fix slicing failure when using Randomize Infill Start in some cases.
Restore reminder to sync materials with your printer when using cloud printers with custom materials.
The tool bar should no longer show up in the monitor stage.
Exporting materials should now retain settings unknown to Cura as well.

Printer definitions, profiles and materials:

Improved profiles for PVA and support for Ultimaker printers.
Adjust retraction speed and distance for Voron, contributed by @Haxk20 and @cbc02009
Heat up extruder and build plate at the same time for Ender 3 Pro, contributed by @xDazld.
Add new Tough PLA colours.
Add DD0.4 print cores for Ultimaker printers.
Add MakerGear M2 printer, contributed by @wanders78746.
Add Trimarker Nebula Plus printer, contributed by @MatiGabaglio.
Various small profile improvements.

Community translations:

Updated the Brazilian Portuguese translation, contributed by @Patola.
Updated the Czech translation, contributed by @sustmi.

Known critical issues:

The placement of the seam has gotten more scattered than in previous releases.
Support is sometimes missing in detailed parts, where previous releases supported them properly.

Ultimaker Cura 5.0.0

Watch the launch event to learn more about Ultimaker Cura 5.0.

New slicing engine
Following special beta releases to test the Arachne engine, we are pleased to announce our new slicing engine is here in Ultimaker Cura! This all-new engine uses variable line widths when preparing files for printing, meaning you can now print thin and intricate parts more accurately and with greater strength.

Renewed the Ultimaker Cura Marketplace
We have streamlined the workflow for accessing the Ultimaker Marketplace inside of Ultimaker Cura. The UI has been improved and it’s now easier and faster to find and install plugins and material profiles.

Improved print profiles for Ultimaker printers
The new slicing engine in Ultimaker Cura 5.0 has helped us to improve our print profiles. This means that users of Ultimaker printers can achieve speed increases of up to 20%.

From version 5.0 onwards - Ultimaker Cura is only supported on operating systems actively maintained by their software manufacturer or community. This means Windows 7 and MacOS 10.14 will no longer be supported.
Ubuntu 18.04 is also no longer supported because of the update to Qt6.
