A full-color 360° figurine.

The front follows the photo. The back, which the photo can't show, is inferred by AI. Before molding, have a sculptor refine the details.

09 / FAQ

Common
questions.

Anything else? Email us:
contact@mofa-ai.com

How accurate is 3D from a single photo?

The front follows the photo; in the figurine case the silhouette matched the photo by 86%. The back and sides are inferred by AI, so for molding we recommend having a sculptor refine the details first.

Can my mold maker use your files directly?

Every part comes as STEP and IGS, plus an assembly STEP. They open in UG, Rhino and SolidWorks. Draft angles, shrinkage, tolerances and gates are set together with your mold maker before tooling.

What if I don't have dimensions?

We start from an assumed size, for example 80 mm tall for the kids' trike, and finalize it once the factory confirms.

Do I need to install any software?

No. Photo to 3D runs on a phone in about 10–15 minutes, with no Windows PC needed. Your customer opens a link to rotate the model and approve it or ask for changes.

Can I get a prototype first?

Yes. The STL file can go straight to a 3D printer, so you can check the look and feel before paying for molds.

How do I send my files?

Email them to contact@mofa-ai.com. Photos as JPG, PNG or HEIC; 3D files as STL, OBJ or GLB; artwork as .ai, PDF or SVG.
