Download Ultimaker 3.5 beta today to preview the latest features. In this release, we’ve implemented new bug fixes and stability enhancements for better performance, a new monitor page for better consistency with Cura Connect, extra hotkeys to make print preparation simpler, and much more.

Please note: We’ve thoroughly tested this beta version, which offers great functionality and improved features. However, it’s still in the beta stage, which means we can’t guarantee the same print reliability as our stable versions. If you’re working on an important project, we strongly recommend that you use the latest stable version of Ultimaker Cura.

User experience

New tool hotkeys. New hotkeys have been assigned for quick toggling between the translate (T), scale (S), rotate (R), and mirror (M) tools.

File menu. New behavior for the file menu. “Save” now saves projects, and “Export” saves other file types.

Project files use 3MF. We’ve retired ‘.curaproject’ extensions from project files. These have been replaced with 3MF extensions. You can still open the old extension in this version.

Open recent projects. Project files can now be found in the ‘Open Recent’ menu.

Materials preferences. This screen has been redesigned to improve the user experience. Materials can now be set as favorites, so they can be easily accessed in the material selection panel at the top-right of the screen.

Camera maximum zoom. The maximum zoom has been adjusted to scale with the size of the selected printer. This fixes third-party printers with huge build volumes to be correctly visible.

Monitor page. We’ve remodeled the monitor page for better consistency with the Cura Connect ‘Print jobs’ interface. This means more control from within Ultimaker Cura, and less switching between interfaces.

Monitor improvements
Updated monitor for a more consistent experience with Cura Connect

Save project. Saving the project no longer triggers a reslice. This means your printing strategy after a long slice is preserved!

Removed .gz extension. Saving compressed GCODE files from the save dialog has been removed because of incompatibility with MacOS. If sending jobs over Wi-Fi, GCODE is still compressed.

Slicing enhancements

Prime tower reliability. The prime tower has been improved for better reliability with two materials that have less reliable adhesion properties.

Support infill line direction. The support infill lines can now be rotated to increase support capabilities and reduce artifacts on the model. Specify an angle of rotation, and the existing pattern will be rotated.

Support infill line direction 0
Support infill line direction 30

Fan speed override. New setting to modify the fan speed of supported areas. This setting can be found in Support settings > Fan Speed Override when support is enabled.

Improved processing of overhang walls. Overhang walls are detected and printed with different speeds. It will not start a perimeter on an overhanging wall. The quality of overhanging walls may be improved by printing those at a different speed.

Minimum polygon circumference. Polygons in sliced layers that have a circumference smaller than the setting value will be filtered out. Lower values lead to higher resolution meshes at the cost of increased slicing time. This setting is ideal for very tiny prints with a lot of detail, or for SLA printers.

Initial layer support line distance. This setting enables the user to reduce or increase the density of the support initial layer in order to increase or reduce adhesion to the build plate and the overall strength.

Extra infill wall count. Adds extra walls around infill.

Infill line multiplier. Converts each infill line to a multiple of this value to create stiffer infill.

Infill line multiplier
Infill lines x 1
Infill line multiplier x3
Infill lines x 3

Connected infill polygons. Connecting infill lines now also works with concentric and cross infill patterns. The benefit is stronger infill and more consistent material flow, reducing the need for retractions.

Minimum wall flow. New setting to define a minimum flow for thin printed walls.

Third-party printers

Machine profiles for TiZYX, Winbo, Tevo Tornado, Creality CR-10S, and Wanhao Duplicator have been added. Profiles for Deltacomb and Dacoma have been updated.

Bug fixes

We’ve fixed a lot of issues in this release, including better temperature stability by removing excess M109 commands in GCODE, bugs with modifier meshes, removing unnecessary travel moves, and a consistent order for batch-printed models.
