Current Version 3 release

Save what works. Tune what matters.

Keep named print presets, adjust Z-hop, inspect cleaner first-layer paths, and export through the route provided for the selected printer profile.

Live in Version 3

See more of the toolpath before you print.

Review walls, infill, travel, and supports clearly before you export.

Metal-powered preview

See complete active-layer walls and infill, scrub through individual layers, or play the print from the first layer up.

Adaptive infill

Place more structure near walls and surfaces while keeping the deep core more open.

Arbor supports

Build branching supports that merge into trunks, steer around the model, and reach critical overhangs.

Named print presets

Save settings you want to reuse, then apply, rename, duplicate, or delete them without changing the printer profile.

Z-hop and first-layer control

Tune nozzle lift from 0 to 2.0 mm and review cleaner paths across first and bottom solid layers.

Clear export paths

Move G-code through Files or sharing, removable media, M3D Desktop Host File, or compatible local Klipper and Moonraker workflows.

From model to machine

From model file to reviewed G-code.

Use EFUGY when a model arrives away from your desktop, when you want to inspect a job beside the printer, or when you need a focused handoff through Files and your existing transfer setup.

  1. 01

    Import the model.

    Open an STL or OBJ from Files, iCloud Drive, AirDrop, or another iOS sharing workflow.

  2. 02

    Prepare the job.

    Check dimensions and build-volume fit, then choose a printer profile, material, nozzle, quality, infill, support, and placement.

  3. 03

    Review the toolpath.

    Inspect the model and generated paths in 3D or top view before you commit material and machine time.

  4. 04

    Export the G-code.

    Save or share G-code through iOS, then verify temperatures, motion, build volume, and printer-specific start and end behavior.

Know your starting point

Check the printer, profile, and test status.

See which profiles are included, which have been tested further, and which still need a careful first run on real hardware.

Result: import, slicing, toolpath review, and export completed with a preserved G-code file.

What this shows: The model was imported, sliced, previewed, and exported. It is not presented as a verified physical print.

Version 3 workspace
