Printing an AI model in Bambu Studio: start to finish

Before you open Bambu Studio

Export the model in a printable format. Vi3W exports OBJ, GLB and FBX; for printing, choose OBJ. Bambu Studio imports OBJ along with STL, 3MF and STEP, so you don't need to convert. If you'd like to inspect and repair the mesh first, make it watertight in Blender.

Step 1: Import

Drag the OBJ onto the plate, or use the import button. If Bambu Studio detects mesh errors, it shows a warning and offers to repair. Accept the repair for small problems.

If the model arrives as several parts, decide whether to keep them separate (for different colours or orientations) or assemble them.

Step 2: Scale

AI models have no real size, so check the dimensions in the object's settings. Enter the size you want in millimetres with uniform scale on. A desk figurine: 80–120 mm tall. A first test: 40–50 mm. Scaling a model for printing covers units in more depth.

Step 3: A flat bottom

The model needs a flat surface on the plate.

• Use Lay on face to put a flat face down.
• If there's no flat face, use the Cut tool to slice off the bottom slightly, giving a flat base.
• For figures, consider adding a base in Blender before import.

Step 4: Orientation

• Minimise steep overhangs.
• Keep supports away from detailed or visible surfaces (faces, fronts).
• Tall, thin models are more stable lying down or with a brim.

Step 5: Supports

• Tree supports suit organic, AI-generated shapes like figurines and creatures: they touch less of the surface and are easier to remove.
• Use support painting to add or block supports in specific areas.
• Check the preview: every overhang should be supported or printable.

Step 6: Profiles

• Choose your printer, the filament (PLA is easiest for figurines) and the process profile.
• For detailed figures, a finer layer height gives smoother curves at the cost of time.
• Add a brim for small contact areas.

Step 7: Slice and inspect

Slice, then scrub through the layer preview. Look for:

• Floating islands (unsupported parts appearing mid-air).
• Very thin walls that print as single lines or vanish.
• Gaps in the shell that suggest an unrepaired hole.

Fix in the model or settings, re-slice, then print.

Multicolour

With an AMS, you can paint colours onto the model in Bambu Studio and print in several filaments. See multicolour 3D prints from AI models.

Quick checklist

1. Imported, errors repaired.
2. Real size in mm, uniform scale.
3. Flat base on the plate.
4. Orientation that hides supports.
5. Tree supports where needed.
6. Profile set; brim for small footprints.
7. Layer preview checked.
