FIVE TOOLS
CRAMMED INTO ONE STUDIO.

Stop bouncing between mesh fixers, painters, splitters and analyzers. Audja Pro takes a model from messy import to print-ready 3MF in a single workspace — fast.

01 /// PAINTING

Auto Region Detection

One-click analysis identifies regions like face, hair, clothing and props, then assigns filament colors so masking by hand becomes the exception.

CLOUD-ASSISTED · NEEDS NET
02 /// SPLITTING

Smart Key-Cut

Slice oversized models along any plane and join with cube, octagon, dovetail or puzzle-lock keys. Tune clearance for your printer's tolerance.

WORKS OFFLINE
03 /// REPAIR

Auto Mesh Repair

On import: addresses non-manifold edges, holes, flipped normals, self-intersections — so you start from a cleaner mesh.

04 /// ANALYSIS

See Failures Before The Slicer Does

Wall-thickness heatmaps, overhang highlighting, mesh inspection reports and component cleanup. Find weak spots while you can still fix them with a brush — not glue.

05 /// EXPORT

Native Multi-Color 3MF

Painted regions and assignments embed directly in the 3MF — ready for slicers like OrcaSlicer, Bambu Studio and PrusaSlicer that read multi-color 3MF.

THREE ROOMS.
ONE WORKFLOW.

Painting, geometry editing, and analysis live in the same project. Switch context without switching apps, file formats, or losing history.

DROP A MODEL.
GET A 3MF.

The full path from raw mesh to slicer-ready file — usually in one sitting.

STEP 01

DROP

Drag-drop STL, OBJ, FBX, 3MF, PLY or STEP into the viewport.

STEP 02

REPAIR

Audja addresses non-manifold edges, holes and flipped normals on import.

STEP 03

PAINT

Run automatic region detection, refine with brushes and smart fill.

STEP 04

CUT

Use Smart Key-Cut to split oversized models with interlocking joints.

STEP 05

ANALYZE

Check wall thickness and overhangs. Fix what the slicer would flag.

STEP 06

EXPORT

Save a multi-color 3MF. Open it in your slicer of choice.

Audja Pro is in active beta. That means rapid iteration, a direct line to the team, and the chance to influence what ships when it leaves beta.

  • Free during beta. No subscription. No card.
  • Direct feedback channel — bugs and ideas reach engineers, not a queue.
  • Rough edges expected. Fixes ship fast.
  • Cloud features depend on backend availability.

SLICERS

Audja exports multi-color 3MF. Examples of slicers that read multi-color 3MF include OrcaSlicer, Bambu Studio and PrusaSlicer. Printer setups vary.

PRINTERS

Any multi-filament FDM workflow that accepts multi-color 3MF: AMS-style systems (Bambu Lab A1, P1S, X1C), Prusa XL or MMU-based setups, and similar. Single-extruder printers can still use Audja for repair, splitting and analysis.

QUESTIONS,
ANSWERED.

The honest version. If something's missing, ping us through the beta channel.

WHAT DOES AUDJA PRO ACTUALLY DO?
It prepares 3D models for multi-filament printing. Automatic mesh cleanup on import, painting and segmentation tools to assign filament colors to mesh regions, smart splitting for prints too large for the bed, boolean editing and modifiers, printability analysis (thin walls, overhangs), and export of multi-material 3MF files that carry your color assignments into common slicers.
DOES IT NEED INTERNET?
Only one specific step — the automatic region detection that uses our remote vision model — needs internet. Everything else (manual painting, smart fill, geometric segmentation, Smart Key-Cut, booleans, repair, export, most analysis) runs fully offline once installed.
WHICH FILE FORMATS ARE SUPPORTED?
Import: STL, OBJ, FBX, 3MF, PLY, STEP. Auto-repair runs on import. Export: multi-color 3MF with embedded paint assignments.
WHICH SLICERS WORK WITH THE 3MF?
Any slicer that supports multi-color 3MF. Commonly cited examples include OrcaSlicer, Bambu Studio and PrusaSlicer. Setup details and material assignment behavior can vary between slicers and printers, so always do a final check inside your slicer before printing.
WHICH PRINTERS DOES AUDJA SUPPORT?
Audja produces 3MF files — it doesn't talk to a printer directly. Any multi-filament FDM workflow that reads multi-color 3MF should work, including AMS-style systems (Bambu Lab A1, P1S, X1C), Prusa XL and MMU-based setups, and similar. Single-extruder printers can still use Audja for repair, splitting and analysis.
HOW DOES AUTOMATIC PAINTING WORK?
You load a model, open the color panel, and run analysis. The system detects logical regions (face, hair, clothing, props) and assigns filament colors. You then refine with the brush, smart fill, lasso, gap fill and other tools. Processing time scales with model complexity. This step is cloud-assisted and requires internet.
WHAT IS SMART KEY-CUT?
A splitting tool for models too large for your bed. You position a plane, pick a connector — cube, octagon, dovetail or puzzle lock — and tune clearance to match your printer's tolerance. Cut, repeat for multi-piece prints, and the joints align cleanly during assembly.
WHAT DOES AUTO MESH REPAIR FIX?
Common defects that cause slicer headaches: non-manifold edges, holes, flipped normals, and self-intersections. Repair runs automatically on import and can be triggered manually from the repair panel. The mesh inspection report tells you exactly what changed and what's left.
WHAT KIND OF ANALYSIS IS BUILT IN?
Wall-thickness heatmap, overhang detection (highlights surfaces past your angle threshold), and a mesh inspection report (triangle count, volume, dimensions, non-manifold edges, holes, components). Plus component cleanup to remove floating fragments or unwanted internal bits.
SYSTEM REQUIREMENTS?
Windows 10 or 11 (64-bit), GPU with OpenGL 4.3+, 4 GB RAM minimum, 8 GB+ recommended for large models. macOS and Linux are not supported yet — they may be considered later.
UNDO HISTORY AND AUTOSAVE?
Yes. Full undo / redo for strokes and edits, and automatic project saving so you don't lose work to a crash or a wrong click.
WHAT DOES "BETA" MEAN HERE?
Active development. Features land quickly, rough edges exist, and feedback has unusual leverage on what ships in v1.0. The beta is free, and bug reports / feature requests reach the engineering team directly.
WILL AUDJA STAY FREE?
During beta, yes. We're focused on getting the product right first. We're not announcing pricing or plans yet — beta participants will hear before any change.
HOW DO I REPORT BUGS / REQUEST FEATURES?
Once you join the beta, you'll get a feedback link. Bug reports and feature ideas go straight to the team — not a triage queue.
