Generate with printing in mind
Choose a strong silhouette and avoid impossibly thin floating details. A visual model does not encode wall thickness, tolerances, balance or assembly clearances.
- Prefer solid connected forms.
- Simplify fragile details.
- Plan separate parts for orientation or assembly.
Set scale and thickness
Establish real units in Blender, CAD or a repair tool. Measure minimum walls, pins, gaps and embossed details against the printer, material and nozzle or exposure profile.
- Do not scale after setting tolerances.
- Hollow resin parts intentionally and add drain holes.
- Check center of mass for freestanding objects.
Repair the mesh
Find holes, self-intersections, duplicate faces, internal shells, inverted normals and non-manifold edges. Decide whether automatic repair preserves the intended shape.
- Make the intended volume watertight.
- Remove internal geometry.
- Recalculate and visually inspect normals.
Choose STL or 3MF
STL is widely supported but carries geometry without rich scene data. 3MF can preserve more structured information where the toolchain supports it. Confirm units after import either way.
- Open the exported file in a new slicer project.
- Check physical dimensions.
- Keep a higher-fidelity source file for edits.
Supports, orientation and slicing
Orient the model around strength, visible surfaces, support access and print time. Inspect every layer preview for islands, thin walls and unexpected internal paths.
- FDM: consider overhangs, bridging and layer strength.
- Resin: consider suction, drainage and support marks.
- Run the slicer's mesh warnings and preview.
Printability limits
No AI preview can guarantee a successful print. Machine calibration, resin or filament, environment, slicer settings and geometry all affect the result. Start with a small test when failure would be costly.
- Inspect topology, normals, UVs and polygon density before downstream use.
- Confirm the active plan, credit cost, privacy and commercial terms in Studio.
- Run the asset through the target tool, engine or slicer instead of trusting the preview alone.
