## What it is
Ultimaker Cura is a state-of-the-art 3D model slicing application that prepares models for 3D printing by converting them into G-code. It is a cross-platform desktop GUI built on the Uranium framework with PyQt6/QML, featuring hundreds of settings and community-managed print profiles.

## Use cases
- slice 3D models into G-code for my 3D printer
- prepare STL files for printing with custom settings
- manage print profiles for different printers
- preview and orient models before printing
- add support for a new 3D printer machine profile
- convert 3MF files to printer-ready G-code

## When to choose
- you need a mature, free slicer with extensive printer profiles
- you want a full GUI for preparing 3D prints
- you need plugin extensibility and community support

## When to avoid
- you need headless/CLI-only slicing (use CuraEngine directly)
- you need a slicer for non-FDM printing technologies

## Facets
- artifact type: application
