Ultimaker Cura 5.0 has already been released and these are its news

Ultimaker Cure

The release of the new version of Ultimaker Cura 5.0, which provides a graphical interface for preparing models for 3D printing (cutting).

Based on the model, the program determines the scenario for the operation of a 3D printer during the sequential application of each layer. In the simplest case, just import the model in one of the supported formats (STL, OBJ, X3D, 3MF, BMP, GIF, JPG, PNG), select the speed, material and quality settings and send the print job . There are plugins for integration with SolidWorks, Siemens NX, Autodesk Inventor, and other CAD systems. CuraEngine is used to translate a 3D model into a 3D printer instruction set.

Main news in Ultimaker Cura 5.0

In this new version of Ultimaker Cura 5.0, it is highlighted that the UI was changed to use the Qt6 library (previously, the Qt5 branch was used). The transition to Qt6 made it possible to provide support for working on new Mac devices equipped with an Apple M1 chip.

Another change that stands out in this new version is that a new engine is proposed to cut in layers: Arachne, which uses variable line width when preparing files, allowing for increased printing accuracy of fine and complex details.

In addition to this, it is also highlighted that the interface of the catalog of accessories and materials has been updated from Cura Marketplace, integrated into the application. Simplified search and installation of plugins and material profiles.

On the other hand, we can also find the improved profiles to print on Ultimaker printers. Printing speed has increased up to 20% in some cases.

Of the other changes that stand out from this new version:

  • Added a new splash screen that appears when the app starts and suggested a new icon.
  • Updated digital build plates for Ultimaker printers.
  • The Minimum Wall Line Width parameter has been introduced.
  • Added settings for metal 3D printing.
  • Added support for plastic shrinkage compensation when printing with PLA, tPLA, and PETG materials.
  • Improved selection of default line widths for printing spiral forms.
  • Increased visibility of options in the interface.
  • Fixed bug where maximum resolution/deviation was not applied to surface mode
  • Fixed a bug where seam placement was not even.
  • Fixed a bug where top surface skin layers would not work.
  • Fixed a bug where speed was not being respected in flow settings
  • Improved slice preview quality of scale models.

How to install Ultimaker Cura on Linux?

For those who are interested in being able to install this application on their system, they can do so by following the instructions that we share below.

Generally for Linux, the developers of Cura offer us an AppImage file which we can obtain from the official website of the application. The link is this.

Or for those who prefer to use the terminal, they can get the package by typing the following command:

wget https://github.com/Ultimaker/Cura/releases/download/5.0.0/Ultimaker-Cura-5.0.0-linux.AppImage

After downloading the package we are going to give you execution permissions. We can do this by secondary clicking on the package and in the context menu we go to the properties option. In the window that was opened, we position ourselves on the permissions tab or in the "permissions" section (this varies a bit between desktop environments) and we will click on the "execution" box.

Or from the terminal we can give the permissions by executing the following command:

sudo chmod x+a Ultimaker-Cura-5.0.0-linux.AppImage

And voila, now we can run the installer by double clicking on the file or from the terminal with the command:

./Ultimaker-Cura-5.0.0-linux.AppImage

Finally, in the case of Arch Linux or derivatives, We can install the application directly from the Arch Linux repositories (even though the version is an older one). To do this we just have to type:

sudo pacman -S cura
