EFUGY 3D Slicer

Slice STL and OBJ models on iPhone or iPad. Save named presets, tune Z-hop, inspect every layer, and export locally or use Moonraker with compatible profiles.

A 3D slicer built for iPhone and iPad.

EFUGY turns STL and OBJ models into G-code on your device. Import a model, choose a printer and material, tune the print, inspect toolpaths layer by layer, and export through Files or Share. No account is required.

SLICE ON DEVICE • Local-first mesh preparation and G-code generation • STL and OBJ model import, plus G-code import for preview • Printer-aware bounds, temperature, motion, and toolpath validation • Automatic on-device saving for the active printer and settings

TUNE EACH PRINT • Basic controls for quick setup and Advanced controls for precise tuning • Named print presets with Save As, Apply, Rename, Duplicate, and Delete • Adjustable retraction, Z-hop, speed, cooling, walls, top/bottom layers, adhesion, and temperature • Grid, Lines, Wave, and Adaptive infill • Arbor supports for printable organic support paths • Material presets for PLA, PETG, ABS, ASA, TPU, and more

PREVIEW EVERY LAYER • Interactive 3D and top toolpath views • Build-up and single-layer inspection with layer scrubbing and playback • Clear wall, infill, travel, and support visualization • Metal-powered rendering designed for iPhone and iPad

WORK WITH YOUR PRINTER • 39 visible retail printer profiles, each with a software-validated export route • Reviewed, Community, Manufacturer Beta, belt, and construction workflows remain clearly identified • Export validated G-code through Files or the iOS Share sheet where the selected profile supports printer-ready G-code • Optional local-network transfer for reviewed compatible Klipper/Moonraker profiles only • Compatible Klipper output includes 48 x 48 and 300 x 300 model thumbnails for supported screens and interfaces • A dedicated M3D Desktop Host File for the original M3D Micro and Micro+, intended only for the stock desktop host's Print from GCode file workflow • The current Prusa catalog entry is the MK3S+ Community profile with supervised Files/Share export

LOCAL BY DESIGN Core slicing, preview, presets, and file export happen on your device. No account is required, and your model does not need to be uploaded to a remote slicing service. Optional Moonraker communication occurs only when you configure and choose a compatible local printer.

Printer profiles are independent compatibility configurations, not manufacturer certification. Community and Beta profiles require careful Preview review and a supervised first print. Availability varies by printer, firmware, nozzle, material, and export route.
