Version 3 makes every layer easier to inspect.

EFUGY Version 3 is available with a production Metal renderer, Adaptive infill, more capable Arbor supports, stronger narrow-feature perimeters, faster raw G-code import, and a growing printer-profile catalog.

Live in Version 3

See more of the toolpath before you print.

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

Live in Version 3

Production Metal preview

A smoother, richer renderer shows complete active-layer walls and infill with high-contrast toolpath categories, layer scrubbing, and cumulative playback.

Live in Version 3

Adaptive infill

Adaptive infill places more structure near walls and surfaces while opening the deep core, balancing local support with less uniform interior density.

Live in Version 3

Arbor supports, refined

Branches merge into efficient trunks, steer around the model, and reach more critical overhangs with a clearer preview.

Live in Version 3

Detailed shapes hold together

Improved narrow-feature perimeter generation keeps curved text and small shapes better defined during toolpath construction.

Live in Version 3

Practical defaults

Standard non-3DCP prints begin at a 0.20 mm layer height with three walls by default. You can review and adjust the job before slicing.

Live in Version 3

Profiles, import, and transfer

Version 3.2 adds the Easythreed K10 Community Beta profile, refines the QREATTE Slice1 Manufacturer Beta profile, and preserves strict memory, cancellation, and validation controls for raw G-code import.

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.

Creator testing

Real printers make better profiles.

Makers, artists, educators, and printer specialists can help EFUGY test real machines, materials, and mobile handoffs. Bring the setup you know, try a focused workflow, and share what happened.
