From a picture to a checked STL.

The studio writes binary STL of the current pose, geometry only, in your browser; nothing is re-uploaded and nothing is charged. STL has no colour, no texture and no units, so the file carries the model’s scene size and slicers assume millimetres. Generated characters use normalised dimensions, so read the reported size in the STL checker or your slicer and scale deliberately: a 1.8 m character is an 1,800 mm print at scale 1.

The studio also writes 3MF of the same pose, in millimetres at a print height you set (100 mm unless you change it), Z up and standing on the plate, so it arrives at the right size. The copies of each point that UV seams split are welded, so a closed skin is one closed shell; the export reports whether it is closed and does not require it. The 3MF was checked with lib3mf and trimesh.

A posed export bakes the skin deformation of that frame into the surface. That is what makes a posed figurine possible from a rigged model, and it is also why you should inspect the joints in the pose: a knee that pinches in the deformation report will pinch in the print. Rest pose is the safest export when in doubt.

A model with separate parts, such as a rider and a mount, exports as several shells. That can be correct. What needs attention is a boundary edge on what should be a closed surface, a non-manifold edge, or an inside-out verdict, all of which the checker reports from the actual triangles rather than the preview.

The free STL repair tool joins open seams, closes holes bounded by simple loops and turns flipped or inside-out faces, then shows the numbers from the checker before and after. It does not thicken walls against your nozzle or resin, merge overlapping parts or know your build volume. Check the layer view in your slicer as well. A successful generation, conversion or repair is not a printability certificate, and Bake3D does not claim that every model prints without changes.

A mesh is 30, 40 or 55 credits by quality tier, and High carries the most surface detail into a print. A rig adds 25, so a Standard mesh with its rig is 65 credits, about $3.12–4.06 at pack rates; the rig is optional for printing and only useful if you want a posed export. STL, 3MF and OBJ exports are free, as are the browser converters and the checker. A free readiness check of your photo quotes the exact price before you pay, and the Single pack ($5, 80 credits) covers one High model, or a Standard model with its rig.

Charges are made when a job is accepted, and what a job does not deliver is refunded. Models made only with the free sign-up credits have a personal-use license, which covers printing for yourself; selling prints needs the commercial license that comes with purchased credits, from a $5 pack or a Pro ($29 a month) or Studio plan. See the pricing page for the table and the marketplaces page for licensing detail.
