Cura was developed by Ultimaker to make 3d printing as easy and streamlined as possible. Cura contains everything you need to be able to print a 3d file. It works with all Ultimaker printers, as well as those from RepRap and Printrbot. Cura is easy to install and contains the latest firmware as well as the calibration files for the 3d printer. Version 5.0 of Cura has been released and the following changes and improvements have been made to it:

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