# Image to 3D model from a single picture

> Upload a photo, drawing or render and PrintPal's AI rebuilds it as a full 3D model with a front, sides and back. Download it print-ready as STL, or as OBJ, GLB or a multi-color 3MF.

Image to 3D, also called 2D to 3D or photo to 3D model, takes one flat picture and produces a closed 3D mesh. Modern image-to-3D AI is trained on large libraries of 3D objects, so it can estimate depth from shading and silhouette and infer the sides it cannot see. That is what makes a single photo enough, with no scanning rig or modeling skills.

PrintPal is built for people who want to print the result. Generated meshes are repaired for slicing, tiny models are scaled up to a printable size on download, and the same generation can be exported as STL, OBJ, GLB or PLY, or reduced to filament colors for a multi-color 3MF.

## How it works

1. **Upload an image.** PNG, JPG, WebP, HEIC, SVG and more. One subject, plain background.
2. **Sign in.** Free account, no credit card. Your image comes with you.
3. **Generate.** About 30 to 60 seconds at Draft quality.
4. **Download and print.** STL or OBJ on Free; GLB, PLY and multi-color 3MF on Pro.

## Same model, every format (measured)

Same 998,810-triangle knight exported with trimesh; the GLB is the download as it came from PrintPal. The 3MF holds geometry only; a painted multi-color 3MF adds a little for the color data.

## FAQ

### What is image to 3D?

Image to 3D is AI that turns a single 2D image into a 3D model. It estimates depth from shading and outline, infers the hidden sides, and outputs a mesh you can download, edit and print.

### Is "2D to 3D" the same thing?

Yes, for still images. "2D to 3D", "photo to 3D model", "picture to 3D model" and "image to 3D" all describe turning a flat picture into a 3D object.

### Is PrintPal's image to 3D free?

Yes. The Free plan includes 10 generations a month at Draft quality with STL and OBJ downloads, and no credit card. Pro adds Refined and Production quality, full color, GLB, text-to-3D and commercial rights.

### How accurate is a 3D model from one image?

The visible side follows the image closely and the hidden side is a plausible inference. Proportions are good; exact measurements are not guaranteed, so use CAD for parts that must fit.

### Which image formats can I upload?

PNG, JPG and JPEG, WebP, HEIC and HEIF, SVG, AVIF, GIF and BMP. Less common formats are converted in your browser first.

### Which 3D formats can I download?

STL and OBJ on every plan; GLB and PLY on Pro and Studio; and a multi-color 3MF from full-color models on Pro.

### Can I 3D print the models?

Yes, that is what PrintPal is built for. Meshes are repaired for slicing and open in Bambu Studio, OrcaSlicer, PrusaSlicer, Cura and resin slicers.

### Is there an image to 3D API?

Yes. The [PrintPal API](https://printpal.io/api/documentation) exposes image-to-3D and text-to-3D generation, status polling and downloads, with Python and JavaScript SDKs.
