The original
Orca-Flashforge
Flashforge's slicer based on OrcaSlicer, tuned for its Adventurer and AD5X 3D printers.
Replacements
Listings that take over the same core job as Orca-Flashforge.
OrcaSlicer
A slicer built around calibration, with temperature towers and flow tests you run from inside the program.
OrcaSlicer is the AGPL-3.0 upstream that Orca-Flashforge builds on, with a larger community and broad profiles, but no official Flashforge Adventurer and AD5X tuning.
PrusaSlicer
Prusa Research's slicer, based on Slic3r, for both filament and resin printers and no account required.
PrusaSlicer is AGPL-3.0 open source, supports filament and resin printers without an account, and exposes fewer calibration tools, with Flashforge printers needing profile work.
UltiMaker Cura
The most widely used free slicer for filament 3D printers, with profiles for hundreds of machines.
UltiMaker Cura is an LGPL-3.0 slicer with profiles for hundreds of printers and a plugin marketplace, though it is heavier to start and has thinner calibration tooling.
ElegooSlicer
ELEGOO's open-source FDM slicer, based on OrcaSlicer, for Centauri, Neptune and other FDM printers.
ElegooSlicer is another OrcaSlicer-based open-source slicer that works with most FDM printers, but its official profiles target ELEGOO Centauri and Neptune machines.
Snapmaker Orca
Snapmaker's fork of the OrcaSlicer slicer, tuned for Snapmaker 3D printers.
Snapmaker Orca is an AGPL-3.0 OrcaSlicer fork that still supports many non-Snapmaker printers, with official profiles aimed at Snapmaker hardware.
Bambu Studio
Bambu Lab's slicer, built on PrusaSlicer, with project-based workflows, multi-material painting and remote printer monitoring.
Bambu Studio is an AGPL-3.0 slicer with multi-material painting and remote monitoring, built around Bambu Lab hardware, so Flashforge printers need profiles set up by hand.
SuperSlicer
A PrusaSlicer fork with extra fine-tuning settings, generated calibration tests and better thin-wall handling.
SuperSlicer is an AGPL-3.0 PrusaSlicer fork with fine-grained settings and generated calibration prints, maintained by a single developer with a last stable release in 2024.
Simplify3D
Prepare and preview print jobs with a commercial 3D slicer.
Simplify3D is a closed-source commercial slicer that requires a paid license and an appropriate printer profile, with configurable processes and support controls.
