The future of 3D printing is spatial

Slice your models in the space they'll live.

OrcaXR is built spatial-first for Android XR: plate at 1:1 in your room, paint multi-color in mid-air, and ship straight to Klipper over your LAN — powered by a native arm64-v8a build of libslic3r.

Spatial

Plan at the scale you'll print

See exactly how a model fits on the desk it's destined for. Plate, scale, rotate, and slice without ever leaving your room.

Powerful

Desktop-class slicing on a headset

Native arm64-v8a cross-compile of libslic3r v2.3.2 — the same engine OrcaSlicer ships, with no cloud round-trip.

Connected

Direct to your printer

Native Moonraker upload and live job monitoring for Snapmaker U1, Elegoo Centauri Carbon, and any Klipper printer on your LAN.

Why OrcaXR

A spatial slicer that goes deeper than a skin.

Every layer — UI, slicing engine, networking — is tuned for the spatial era, not ported from a desktop window.

Multi-color

Paint your vision in mid-air

Load painted 3MFs from OrcaSlicer or use the FullSpectrum mixed-filament pipeline. Per-triangle paint, supports paint, and seam paint — all spatial.

Engine

Native libslic3r

arm64-v8a cross-compile. The exact same toolpath generator you trust on the desktop, running locally on your headset.

Networking

Moonraker ready

Discover printers on your LAN, upload G-code, and watch the job live. No tablet, no cables, no cloud account.

Privacy

Stays on your device

Slicing runs 100% locally. No telemetry, no analytics, no cloud uploads of your models. Ever.

Spatial slicing

Made for the headset, not retrofitted to it.

OrcaXR is what happens when you delete the desktop assumptions and start from gaze, hands, and depth.

  • 01
    1:1 build plate in your room

    Stand next to the printer. The plate matches your hardware to the millimeter, so fit problems are obvious before they're expensive.

  • 02
    Gaze, pinch, and grab

    Move and rotate models with your hands. Transform gizmos snap to your gaze. Galaxy XR controllers are supported for precision work.

  • 03
    Layer scrubber, suspended

    Pull the layer slider out of a sidebar and into 3D space. Inspect toolpaths from any angle, painted with real per-extruder colors.

  • 04
    Panels orbit the work

    Project, transform, settings, slicing summary — all floating where you need them, never blocking the model.

Compatibility

Headsets and printers OrcaXR talks to.

Headsets

Android XR

  • Samsung Galaxy XR — primary target
  • Other Google Android XR devices

Built on Jetpack XR (SceneCore + ARCore for XR).

Printers

Klipper + Moonraker

  • Snapmaker U1 — 4-extruder toolchanger profile
  • Elegoo Centauri Carbon — 0.2 / 0.4 mm nozzles
  • Any Klipper printer with Moonraker reachable on your LAN

Bring more profiles? PRs welcome.

Not supported

Out of scope

  • Direct USB / serial connections
  • Cloud-only printer accounts (Bambu Cloud, etc.)
  • Phone or tablet form factors — XR-only

By design: keep the surface area focused while the project is young.

Built on giants

OrcaXR stands on a decade of open-source slicing.

We didn't reinvent the slicer — we wrapped a great one in a spatial body. Credit where it's due:

⚠ Use at your own risk

OrcaXR is experimental software.

3D printing involves high temperatures, moving parts, and fire risk. OrcaXR is in early alpha — slicing errors, unexpected G-code, or printer communication failures can happen.

  • Always verify generated G-code in a desktop viewer before printing.
  • Never leave your printer unattended on a job sliced by OrcaXR.
  • The authors and contributors accept no liability for damage to your printer, property, or person.
