FDM Slicers
Convert STL / 3MF / STEP into G-code for filament (FFF/FDM) printers.
The slicer is where most print quality is won or lost. The 2026 landscape is dominated by PrusaSlicer-derived forks (OrcaSlicer, SuperSlicer, Bambu Studio); Cura still has the broadest community profile coverage. See Calibration & Print Tuning for what to do once your slicer is set up.
PrusaSlicer family (the dominant lineage)
- ★ OrcaSlicer — open source (AGPL); fork of Bambu Studio with PrusaSlicer DNA. Best-in-class built-in calibration tests (flow, PA, temp tower, max-volumetric-speed). The default community pick for Voron, RatRig, Bambu, and Klipper users in 2026.
- ★ PrusaSlicer — open source (AGPL); Prusa Research's flagship. Rock-solid, conservative, the upstream that everyone forks. First-class on Prusa hardware.
- SuperSlicer — open source; older PrusaSlicer fork with extra calibration & seam-placement features. Maintenance has slowed since OrcaSlicer absorbed most of its userbase.
- Bambu Studio — partially open source (GPL core, some closed components); Bambu's official slicer. Required for cloud features on Bambu printers; OrcaSlicer is the open alternative.
- QIDI Slicer, Elegoo Slicer, Anycubic Slicer Next, Creality Print — vendor forks of PrusaSlicer / OrcaSlicer. Use the upstream unless a vendor feature is mandatory.
Cura family
- UltiMaker Cura — open source (LGPL); huge plugin marketplace, broadest printer profile coverage. Heavier UI than the Prusa family; still the right pick for some exotic printers and for educators.
- Lulzbot Cura, Dremel DigiLab Cura — vendor forks; usually outdated.
Other / niche
- IdeaMaker (Raise3D) — free, closed source; loved by Raise3D owners and some production shops for tree supports and pause-at-layer scripting.
- KISSlicer — closed source; free "lite" tier, paid Pro. Old-school but still has fans for fine seam control.
- Simplify3D — closed source, paid; once dominant, now mostly legacy.
- Slic3r — original open-source slicer; PrusaSlicer's ancestor. Mostly historical.
- Kiri:Moto — browser-based, open source; runs entirely client-side. Useful as a quick web slicer or for CNC + laser as well.
Built-in / web slicers
- Bambu Handy / MakerWorld — cloud slicing for Bambu printers; consumer-friendly.
- Printables Print Anywhere, Thingiverse / MakerWorld send-to-printer — web pipelines that hand off a 3MF to your local slicer.
Slicer profile sources
- ★ OrcaSlicer's built-in profiles — covers most modern hardware out of the box.
- GitHub: orcaslicer-profiles, voron-orcaslicer, ratrig-profiles — community-maintained profile bundles.
- Printer-vendor GitHub orgs — Voron, RatRig, Sovol, Elegoo all publish official profile packs.
Pick this if…
- Default 2026 pick, FOSS, great calibration: OrcaSlicer.
- Prusa printer or you want the most stable upstream: PrusaSlicer.
- Bambu printer with cloud features: Bambu Studio (or OrcaSlicer for offline / open).
- Exotic printer with no Prusa-family profile: Cura.
- Browser-only slicing or also doing CNC/laser: Kiri:Moto.
