New features and improvements:

- Introduced support-painting: paint on the model to indicate where support should and shouldn't be placed

Take complete control over your supports with our new Support Painting feature. You can now customize exactly where supports are placed simply by brushing them directly onto your 3D model. Whether you want to fine-tune auto-generated structures or paint an entirely custom support pattern from scratch, this intuitive tool gives you absolute authority over your print's stability. By targeting only the necessary areas, you can significantly reduce print times, save filament, and ensure cleaner surface finishes upon support removal.

image - Experimental support for Cura on Windows ARM platforms

With this release, we are excited to introduce an experimental Cura installer built specifically for Windows on ARM architecture. This preview allows users on ARM-powered devices (such as those running Qualcomm Snapdragon processors) to experience the native Cura workflow and performance. Please note that as an experimental release, you may encounter occasional bugs or performance inconsistencies. We highly encourage our community to test it out and share feedback to help us refine the experience.

image - Custom GCode parts are now processed in the engine, to ensure that all the variables have the most accurate value - End-of-print GCode variables are now processed in the engine, to ensure that more accurate values are inserted, contributed by @wawanbreton - Dialogs that were previously created at application boot are now created only when necessary, which saves some boot time and memory - Discard top and bottom surfaces when their settings are identical to skin settings, which avoids printing them separately - Discard very thin infill areas that are printed within skin and disrupts the flow - Improve positioning of models when loading multiple models from a non-project 3MF file - Improved the OpenGL shaders compatibility, contributed by @hellAholic

New Settings:

- Introduced Top/Bottom/Skin Merge Distance, which allows merging those areas together wen they are too small to be printed correctly - Introduced Minimum Infill Line Length, which allows removing unnecessary lines of infill added in small areas

Bug fixes:

- Fixed the most common sources of slicing crashes (those that would have to be worked around by moving the model on the build plate) - Removed an unnecessary and long travel move added when printing supported floating models - Fixed an issue where top and bottom surfaces could be generated, although they were disabled - Fixed the print temperature command of the initial layer when using the 'zigzag' pattern, contributed by @hellAholic - Fixed an issue where the project window could be displayed at an unexpected position

Printer definitions, profiles and materials

- Removed hardcoded T0 in start gcode for anycubic ACE PRO enabled K3 - Fixed multiple bugs in Elegoo Neptune 3 Pro: acceleration, retraction_combing, end gcode ### 5.13.0 — UltiMaker Cura 5.13.0 - Date: 2026-05-28 - Version: 5.13.0 - Original notes: https://github.com/Ultimaker/Cura/releases/tag/5.13.0 - Permalink: https://whatsnew.fyi/product/cura/releases/5.13.0 - **added** — Added the new UltiMaker Factor 4+ printer, including profiles - **added** — Added option to specify file association during the installation of Cura for Windows - **added** — Introduced Infill Start/End Preference settings that give control over the starting location of infill - **added** — Added Support Infill option Lightning, and the following supporting settings: Support Lightning Angle, Support Lightning Overhang Angle, Support Lightning Prune Angle, and Support Lightning Straightening Angle - **added** — Introduced Support Infill Line Multiplier to increase the quantity of infill lines - **added** — Introduced Minimum Hole Area in Brim Support to filter out small holes in the support brim - **added** — Added Temperature Delta Top Surface to print top surfaces at a different temperature - **added** — Added more options to Retract Before Outer Wall to give more control over retraction behavior when traveling to the outer wall - **added** — Added Initial Layer Wall Ordering to give control over the order in which walls are printed for the initial layer - **fixed** — Support blockers now function correctly even when assigned to a disabled extruder and no longer cause slicing conflicts - **fixed** — Fixed an issue where thin support structures would be generated within tree support - **fixed** — Fixed an issue where the tree support interface layer would be missing - **fixed** — Randomized infill now also works for infill skin support - **fixed** — Fixed an issue where Keep or Discard profile user preference would be ignored - **fixed** — Overhanging wall speed was previously applied too aggressively, resulting in extremely slow printing in overhanging areas - **fixed** — Travel speed was applied to layer switches, resulting in high-speed Z-travels - **fixed** — Fixed an issue where certain 3MF files would incorrectly load with an invalid setting configuration - **fixed** — Fixed an issue where certain setting combinations would skip parts of the skin and walls sections - **fixed** — Resolved an issue where slicing would fail when both Raft build plate adhesion and Support Lightning Infill were enabled - **fixed** — Fixed an issue where overhang speed would be applied inconsistently when both Split Infill and Overhang Speed settings were enabled

We are aware that there are clear differences between us and BambuLabs. However, we both share a fundamental commitment to empowering the 3D printing community. Our focus is on supporting creators and pushing the boundaries of what is possible. ##### A nightly build with Painting 🎨 and Bambu 🎋 Once again, two sizeable new features that we'd like to have your feedback on have (nearly) arrived to Cura! - We've introduced a Painting Tool into Cura -- for now, this can be used to paint allowed or disallowed areas for seam, or to _paint on materials_. - Bambu-printers work a little different than most things out there in the 3D printing ecosystem (at least from a slicer perspective) -- so we had to pull out some tricks to get them working together properly with Cura. Also, we've introduced a feature just for builds like this; where you can select if you'd like to 'start clean' or use the current configuration folder -- this helps not contaminate your main config should the alpha still have some issues. -- Also the banner-colour on the top is different from our usual deep blue, to let you know this isn't a normal release (or beta). ###### Painting 🎨 Painting, or various tasks that practically require paint-on functionality, have been a much requested feature for a good while. For now with the first introduction of paint-on in Cura, two of those features are coming along: - Seam painting forces or disallows seams to be present on certain areas of the model. robo_seam_pic robo_seam_pic_result - Material painting can be used to paint the use of different extruders onto, and _into_ areas of the model -- we go a little _deeper_ than our competition though -- the entire model is taken into account, not just the surface. image (15) image (16) We are exploring other painting applications, like Paint On Support, but those are more effort than expected and might not show up in the upcoming release. ###### Known issues 🦟 - Occasionally, simpler(?) models can still generate a wrong UV-map -- a workaround is to _export_ such an object to the .OBJ file-format, and then reload it -- the UV-mapping needed for painting should be correct. **Try the above if painting doesn't seem to work properly at all.** - Painting (especially with multiple materials) may take extra slicing-time -- _and progress isn't communicated to the front-end yet_ -- **this means it may seem 'stuck' for a while after pressing Slice.** - Painting isn't fully optimized yet, which is why we've limited the brush-size for now. (In general, there are some issues with brush-size.) - For painting, undo/redo works with Ctrl-L and Shift-Ctrl-L respectively -- since we don't know if it's wanted that the undo-stacks for (other) model-operations should be the same as the painting ones. - There's some initial slowdown when appl _[Truncated at 4000 characters — full notes: https://github.com/Ultimaker/Cura/releases/tag/5.11-alpha]_ ### 5.10.2 — UltiMaker Cura 5.10.2 - Date: 2025-07-31 - Version: 5.10.2 - Original notes: https://github.com/Ultimaker/Cura/releases/tag/5.10.2 - Permalink: https://whatsnew.fyi/product/cura/releases/5.10.2
