From a phone photo to a 3D print: STL and 3MF for Bambu Studio and OrcaSlicer

You have a figurine, a small sculpture or a gift idea — and a 3D printer. With AI you can go from a phone photo to a printable file without a scanning rig or modeling skills. This guide covers the whole path: the photo, the model, the print-ready file and the slicer.

Step 1: shoot the object

• One clear photo is enough for most objects — a three-quarter view, slightly from above.
• Soft, even light. Harsh shadows get baked into the shape.
• The whole object in frame, not cropped, on a plain background if you can.
• A tricky shape? Add up to three more angles — side and back — with multi-view.

No LiDAR or turntable needed; any recent phone camera works. More tips in turning phone photos into 3D models.

Step 2: generate the model

Upload the photo on Wandy3D and pick Quality, or Best for fine detail. In a few minutes you get a textured 3D model you can spin around and check from every side before you print anything.

Step 3: make it print-ready

A model made for screens isn’t automatically printable: it can have tiny gaps, loose bits or an uneven base. The 3D print option on the model takes care of that:

• Watertight — gaps are sealed, so the slicer sees one closed solid.
• Flat base — the underside is flattened so the model stands on the build plate.
• Real size — choose the longest side in millimeters, from 30 to 400 mm.
• Hollow shell, if you want — 2.5 mm walls save a lot of filament; good for FDM, not for resin.

You also get a short report: the dimensions, an estimated weight in PLA and any walls thinner than 2 mm — fine for resin, possibly fragile on FDM.

Step 4: STL or 3MF

• STL — geometry only; opens in every slicer ever made.
• 3MF — the modern choice: it keeps units and color, and Bambu Studio, PrusaSlicer and OrcaSlicer open it directly.

If your slicer supports 3MF, use it. Print files download with PRO; the format guide explains how they differ from a regular STL export.

Step 5: slice and print

1. Open the file in Bambu Studio, OrcaSlicer or PrusaSlicer. It arrives at the size you picked.
2. Put the flat base on the plate. Add supports only under real overhangs — tree supports keep figurines clean.
3. For FDM, use 0.12–0.16 mm layers for figurines and 0.2 mm for bigger pieces.
4. For resin, print solid, or hollow the model in your resin slicer, which also adds drain holes.

Good first prints

• Figurines, busts and small sculptures
• Tabletop scenery: rocks, ruins, barrels, crates
• Gifts: a figurine of a pet, a copy of a favorite ornament
• Decorative parts — for anything that must fit precisely, measure and adjust the model in CAD: AI geometry is close, not exact

From idea to object in an evening

Photo, model, print-ready file, slicer — the whole path fits into an evening, and most of it is the printer doing its job. Try it with your own photo; new accounts get free credits to start.
