Today we have released the beta testing version of Ultimaker Cura 3.2, to give a sneak peek into new features designed to save time, material, and give you a better quality 3D printing experience.

Please note: Although we have added some useful functionality and tested this beta version to the best of our ability, we cannot guarantee the same print reliability as for our stable versions. If you are working on a very important project, please use the latest stable version.

New printing features

Tree support. Tree support is an experimental tree-like support structure that uses ‘branches’ to support models. Branches ‘grow’ and multiply towards the model, with fewer contact points than alternative support methods. This results in better surface finishes for organic-shaped prints, as well as reduced print time and material use compared to alternative support methods. The user is able to use tree support in conjunction with other types of support material. This setting can be found under the experimental category.

Adaptive layers. With adaptive layers, Ultimaker Cura will compute a variable layer height based on the shape of the model. The algorithm assigns a narrower layer height to sloped surfaces, and a wider layer height to vertical surfaces. The result is high-quality surface finishes with a marginally increased print time. The user is able to specify the maximum variation, variation step size, and threshold. This setting can be found under the experimental category.

UI enhancements

Faster startup. Printer definitions are now loaded when adding a printer, instead of loading every possible printer on startup. This results in a quicker startup process.

Backface culling in layer view. The frame rate of the stage has been doubled by only rendering visible surfaces of the model in the layer view, instead of rendering the entire model. This gives smoother scaling, rotating, and orbiting of models in the layer view.

Multi build plate. When enabled, a new UI element is added to the workspace where the user creates separate build plates in a single session. Each build plate will share print settings that can be sliced and sent to a printer or Cura Connect group without the need to clear the build plate in the software multiple times. The user can arrange each model on the same build plate, or distribute them through to multiple build plates. This option can be enabled in preferences.

View optimization. Quick camera controls introduced in version 3.1 have been revised to create more accurate isometric, front, left, and right views.

Updated sidebar to QtQuick 2.0. The application framework has been updated to increase speed, achieve a better width and style fit, and gives users drop-down menus that are styled to fit the enabled Ultimaker Cura theme, instead of the operating system’s theme.

Hide sidebar. The sidebar can now be hidden/shown by selecting View > Expand/Collapse Sidebar, or with the hotkey CMD + E (Mac) or CTRL + E (PC and Linux). This is to give greater visibility for wider build plates, or build plates on small screens.

Disable ‘Send slice information’. A shortcut to disable ‘Send slice information’ has been added to the first launch to make it easier for privacy-conscious users to keep slice information private. Clicking the disable button will take the user to the preferences, where they can edit preferences accordingly.

Signed binaries (Windows). For security-conscious users, the Windows installer and Windows binaries have been digitally signed to prevent “Unknown application” warnings and virus scanner false-positives.

OctoPrint plugin added to plugin browser. This plugin has moved to the plugin browser. The OctoPrint plugin enables printers managed with OctoPrint to print via the Ultimaker Cura interface (version 3.2 or later).

Improved manual supports. It is now much easier to load models as support structures or prevent supports from being added in certain areas. This is particularly useful when customized supports are required.

Bug fixes

We pride ourselves on delivering professional, quality-tested software. We have fixed several bugs in this version, including crashes due to config files on remote drives, errors triggered by outdated Arduino drivers, center model options resetting object orientations, and the auto arrange model feature.

Let’s go!

Test the latest version of the world’s most advanced 3D printing software and see what the new features have to offer.

We care about our user feedback and want to continue to make the best software available so as always, feel free to give us your feedback so we can implement for the stable release.
