Issue Ultimaker Cura 5.0, package for preparing a model for 3D printing

is available the new version of the package Ultimaker Cura 5.0 , providing a graphic interface for preparing models for 3D printing (Slicing). The project code is written in Python and spreads under the license LGPLV3. GUI was built using the framework uranium , using Qt.

, based on the model, the program determines the 3D printer work scenario when each layer is consistent with each layer . In the simplest case, it is enough to import the model in one of the supported formats (STL, OBJ, X3D, 3MF, BMP, GIF, JPG, PNG), select speed, material and quality settings and send the print task. There are plugins for integration with SolidWorks, Siemens NX, Autodesk Inventor and other CAD. To broadcast the 3D model, the engine of instructions of the 3D printer is used by the engine curaengine .

in new issue :

  • The user interface is translated to the use of the QT6 library (the QT5 branch was previously used). The transition to Qt6 made it possible to support the work on new Mac devices equipped with an Apple M1.

  • A new cutting engine on layers is proposed – Arachne, which uses the variable lines width in the preparation of files, which allows you to increase the accuracy of printing of thin and complex parts.

  • Улучшено качество предпросмотра нарезки отмасштабированных моделей.


  • The interface of the plug -in catalog and materials is updated cura marketplace , built into the application. Simplified operations of the search and installation of plugins and profiles of materials.
  • Improved Printing Prints on Ultimaker printers. Printing speed in some cases increased to 20%.
  • added a new screensaver that appears when starting the application, and a new icon is proposed.
  • Updated digital work tables for the printer Ultimaker.
  • The parameter “Minimum width of the wall line” (Minimum Wall Line Width) is presented.
  • Added settings for 3D printing with metal.
  • Added support for compensation for the shrinkage of plastic when printing using materials PLA, TPLA and PETG.
  • Improved selection of width of the default lines for printing spiral shapes.
  • The visibility of options in the interface is increased.
