Ultimaker Cura 5.0 beta

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

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 beta has helped us to improve our print profiles. This means that users of Ultimaker printers can achieve speed increases of up to 20%.

This is a patch release fixing two important bugs.

Bug fixes:

• Fixed a bug where tree support could go through the model
• Fixed a bug where there were incomplete layers in surface mode

Note: with the tree support fix the X/Y distance for support will now also be applied correctly. See below the difference.

Ultimaker Cura Arachne Engine Beta 2

Our new Ultimaker Cura engine allows you to create parts with ground-breaking quality, strength, and speed. This is made possible by fundamentally redefining how the inside of a model is generated – through adaptive line widths and optimized line positioning.
Earlier this year, we released the first beta of Ultimaker Cura Arachne engine. Which received an overwhelmingly positive response, thank you for all your feedback!
Since the first beta release we've been working on improving the Arachne engine.
Join our discussion on GitHub to provide us with all your feedback.

Back pressure compensation
Print quality is improved through dynamically adjusting print head velocity, which slows down or speeds up depending on the pressure of the material through the Bowden tube.

Printing order filling gaps
Gaps in models are now filled in after placing the outer wall, resulting in less over-extrusion.

Print quality enhancements
All print quality improvements from Ultimaker Cura 4.12 have been added.

New settings:

• Split Middle Line Threshold
• Add Middle Line Threshold
• Expose the Distribution radius of the Inward Distributed strategy

Bug fixes:

• Fixed a bug with concentric skin lines
• Fixed memory usage, contributed by @Piezoid
• Fixed a bug with opening old project files in Arachne
• Fixed a bug where the width was not adjusted
• Fixed a bug with Line Compactness behaviour was inversed for Central Deviation
• Fixed a bug with tiny movements which caused a nozzle slowdown
• Fixed a bug where blobs in g-code were generated
• Fixed a bug with Minimum Wall Line Width setting was used if Print Thin Walls was disabled
• Fixed a bug where the Inner Line Width was wider than the end of the model
• Fixed a bug where Maximum Resolution was not applied for hyperbolic arcs in inner walls
• Fixed a bug where Combing was broken
• Fixed a engine crash within the inset order optimizer with 3 walls, contributed by @Piezoid
• Fixed a bug where the Seam placement was not on the correct corner
• Fixed a bug where the centerline of Central Deviation is not generated
• Fixed a bug with Bottom Skin Expand Distance at zero caused skin to expand beyond walls

Known issues:

• Gaps in inner wall where it has enough space to print one line
• Unwanted travel moves when monotonic order in enabled
• Printer pauses at certain layer creating dripping spots
• Retracted unnecessary travel moves

Note: This is not based on a specific stable version of the front-end of Cura (like '4.12.0' or similar), so there may be issues that have been solved or introduced since then that have little or nothing to do with the variable line width feature-set!

Ultimaker Cura 4.12.1

This is a patch release fixing two important bugs.

Bug Fixes:

• Updated Shapely to version 1.8.0 which, among other things, fixes multiplying objects on MacOS Monterey
• Fixed a bug in Lightning infill where the infill was printed multiple times under certain circumstances

Ultimaker Cura 4.12.0

For an overview of the new features in Cura 4.12, please watch our video.

Lightning infill
The new lightning infill setting lets you to print high-quality top layers but is optimized to use less material and increase your production speed. Special thanks to @rburema and @BagelOrb!

Improved top surface quality
We’ve tweaked the Monotonic setting and made adjustments throughout Ultimaker print profiles. This removes occasional scarring on models and improves top surface quality by default.

Improved horizontal print quality
Resulting in reduction of ringing, improving resolution and overall print quality.

App switcher
The new switcher provides a simpler way to navigate and use other Ultimaker applications, including Ultimaker Digital Factory, Ultimaker Marketplace, and Ultimaker 3D Printing Academy. Reporting bugs to Github is now just one click away, and it’s easier to find the application you need.

Faster start-up
We've shaved 10 seconds from Ultimaker Cura's start-up time by optimizing profile data caching.

Ultimaker Cura 4.11.0

For an overview of the new features in Cura 4.11, please watch our video.

Monotonic ordering
The new Monotonic top/bottom order setting enables users to print parts with smoother top surfaces. This is especially useful for parts that need good aesthetics, such as visual prototypes. Or for parts that benefit from smooth surfaces, such as those that contact-sensitive components.

Complete UI refresh
Look around and you will notice that we have refreshed over 100 icons throughout Ultimaker Cura. The new icons are designed for clarity – resulting in a simpler and more informative slicing experience. Also, when scaling the Ultimaker Cura window, the UI will adapt, resulting in less visual clutter.

Improved digital library integration
Collaborative workflows using the Digital Library are now simpler. Every user with a cloud-connected Ultimaker 3D printer can access stored projects. And we have added a “Search” function to make finding files easier.

Save materials profiles to USB
Users can now save all third-party material profiles to USB. This feature is for Ultimaker S-line printers only and is especially useful for cloud-connected (or offline) printers.

Notifications for beta and plugin releases
Users can now set notification preferences to alert them to new Ultimaker Cura beta and plug-in releases.

Improve logging of errors in OAuth flow
When helping a user with log-in problems it is easier to see where the OAuth flow goes wrong.

Search in the description in the settings visibility menu
When searching in the settings visibility menu you will also search in the description of the settings.

Bug fixes:

From version 4.11 onwards - Ultimaker Cura is only supported on operating systems actively maintained by their software manufacturer or community. This means Windows 7 and MacOS 10.13 will no longer be 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.
