Polycam is the polished default for phone-based 3D capture. Alternatives split two ways: another scanner, or skipping capture altogether when the object does not have to be a specific real one.
Sculpty is first here for a specific reason, and it is not that it scans — it does not. If you are scanning because you need a 3D model of *something like* a chair, generating one from a prompt or a couple of photographs is faster, cheaper and gives geometry that is clean rather than dense. If you need *that exact chair*, scanning is the only honest answer and KIRI Engine is the strongest direct alternative. Sculpty is also the natural second step after either: scan meshes are dense and rarely production-ready, and its remesh, retexture and render tools are what make them usable.
Skips capture entirely when the object does not have to be a specific real one — five engines from a prompt or photo, with clean geometry instead of a dense scan, then remesh, texture, render and print.
Sculpty vs Polycam, side by side →
Try Sculpty free →Real Android support alongside iOS, photoreal and object scan modes, and free capture so you can judge quality before paying to export.
About KIRI Engine →Photo-based reconstruction at 1536³ with true multi-view — closer to scanning fidelity than any prompt-driven generator.
About Hi3D →Premium image and multi-view to 3D with PBR materials and topology control, so the output is production-ready rather than scan-shaped. Also inside Sculpty.
About Rodin →If the point of scanning was to get a manufacturable part, this converts scan data into parametric CAD and exports STEP.
About Backflip →Sampler's AI Delight and Image to Material clean up the lighting baked into captured textures — the professional finish for scan data.

If the object exists and fidelity to it matters, scan. If you just need something that looks like that kind of object, generate — it is faster and the geometry is cleaner.
Yes, and it is the natural pairing: import the mesh into the remesh studio to reduce and retopologise it, retexture it, then render or print it.
