## What it is
OrcaSlicer is a free, open-source G-code generator (slicer) for FDM 3D printers, supporting brands like Bambu Lab, Prusa, Voron, and Creality. It offers advanced calibration tools, fine-grained print quality controls, and tuned profiles for hundreds of printers on Windows, macOS, and Linux.

## Use cases
- slice STL models into G-code for my 3D printer
- calibrate flow rate and pressure advance on a new printer
- generate temperature towers and retraction tests
- tune seam placement and wall settings for better print quality
- create smart supports for complex overhangs
- use pre-tuned profiles for Bambu Lab or Voron printers
- print calibration tests without downloading separate STLs

## When to choose
- you want a free, open-source slicer with deep tuning controls
- you own a Bambu Lab, Prusa, Voron, RatRig, RatRig, Creality, or similar FDM printer
- you need built-in calibration tools to dial in a printer or filament
- you want per-feature overrides for speed, temperature, and pressure

## When to avoid
- you need resin (SLA/DLP) printing support
- you prefer a minimal slicer with only basic settings
- you require commercial vendor support or SLAs

## Facets
- artifact type: application
- maturity: active
- function: graphics, simulation, developer-tools
- domain: hardware, cross-platform, developer-tools
- platform: windows, cross-platform
- tags: 3d-printing, slicer, gcode, fdm, calibration, makers, bambu-lab, prusa, macos, linux, desktop
