About UltiMaker Cura

UltiMaker Cura is one of the most widely used slicers for FDM 3D printing. Made by UltiMaker, it supports the company's own printers and a long list of third-party machines. It offers recommended settings for quick starts and a custom mode with more than 400 settings, plus intent profiles tuned for specific goals. The UltiMaker Marketplace adds material profiles from filament makers and community plugins, and it connects to UltiMaker's Digital Factory for managing printers. Cura is free and open source (LGPL-3.0), with downloads for Windows, macOS and Linux. Hobbyists often find newer slicers such as OrcaSlicer faster to calibrate and better tuned for current high-speed printers, and some users find Cura slower on very complex models.

Best for: Beginners and UltiMaker users who want a well-known slicer with plugins and material profiles.
