AI 3D model generator

AI 3D models for 3D printing

Describe a figurine, a planter or a gift, or upload a photo, and get a textured 3D model in about two minutes. Convert it to STL or 3MF at the height you want, and it opens in your slicer at the right size.

Optimised for the web; the file you download from the studio is full size.

Which format to use: 3MF or STL

3MF records millimetres, so the model can't arrive a thousand times too small. STL works in every slicer. Neither keeps colour; Bambu Studio and Cura can also open the GLB directly.

Units: GLB is in metres; slicers work in millimetres. Converting without scaling prints a 1 m model at 1 mm, so set a height.
Bambu Studio: Opens 3MF, STL, OBJ, STEP and, since 2.7, GLB and glTF. Its texture-to-colour painting can turn a textured GLB or OBJ into filament colours. Draco-compressed GLB isn't supported.
PrusaSlicer: Opens STL, OBJ, 3MF, AMF and STEP. Materials and textures in an OBJ are ignored.
OrcaSlicer: Stable releases open 3MF, STL, OBJ, STEP and AMF. GLB arrives in the 2.5 alpha.
UltiMaker Cura: Opens 3MF, STL, OBJ, PLY and GLB, among others.
Lychee Slicer (resin): Opens STL, OBJ and 3MF.
Printability: Slicers need a closed (manifold) surface; holes stop a model from slicing.

From prompt to finished file

Make the model
Describe one object on a flat base, or upload a clean photo. A front three-quarter view gives the best back side.
Convert to 3MF or STL
Download the GLB and drop it into the free converter. Set the height in millimetres; it's placed flat on the build plate.
Slice and print
Open the file in your slicer, let it repair small mesh errors if it offers, add supports for overhangs, and print.

Prompts to start from

Each one opens Text to 3D with the prompt filled in. The concept image is drawn first so you can check it before meshing.

Tips for better results

Ask for a base
"Standing on a round base" gives a figure a flat bottom that sits on the bed without supports.
Avoid thin parts
Whiskers, antennae and sword tips that look fine on screen are often under 1 mm at print size. Ask for chunky, stylised proportions.
Pick a simple silhouette
One object, no floating pieces. Separate parts print better as separate models.
Check it at size
Scale to the real height before judging detail: a 30 mm miniature and a 200 mm statue need different prompts.

Where AI models fall short

Worth knowing before you plan a project around them.

AI models capture shape, not engineering tolerances. Use CAD for parts that must fit.
Textures don't print on a single-colour printer; only the shape does.
The converter keeps the mesh exactly and doesn't repair it. Slicers fix small errors; badly broken meshes need Blender's 3D Print Toolbox.

Questions

Something else? Ask us and a person will answer.

Can I turn a photo into an STL?

Yes. Upload the photo to Image to 3D, mesh it with Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1, download the GLB and convert it to STL or 3MF on the free converter page.

STL or 3MF?

3MF if your slicer reads it (Bambu Studio, PrusaSlicer, OrcaSlicer, Cura and Lychee all do), because it records units. STL if you're sending it to a print service or an older tool.

Can I print it in colour?

Bambu Studio 2.7 and later can open a textured GLB or OBJ and turn its texture into painted filament colours for multi-colour printing. Other slicers print the shape in the filament you load.

Why does my model come out the wrong size?

GLB is measured in metres and AI models are usually about a metre across. Scale it in your tool, or use the free converter, which can set an exact height in millimetres for printing.

Are the models printable straight away?

Usually, at sensible sizes. Check thin parts and overhangs in the slicer preview and add supports where it suggests.
