Photo to 3D print
A picture becomes a mesh, the mesh is checked for being closed, and what is not closed is said rather than printed.
What you get
A STL from one image, made through whichever image-to-3D generator this deployment can reach — a local worker, a bridged node, or a cloud provider on your own key. The model page states which.
What it costs
Three runs a day are free and render a capped preview on a turntable. The Forge plan exports clean files and adds a monthly allowance; a run on your own provider key is never metered.
What a single image can and cannot give you
One photograph shows one side. The reconstruction is a plausible guess at the rest — a model, never a scan — and every result carries its triangle count and whether it is watertight, read from the exported file.
