Sculptly

Sculptly is a web-based image-to-3D model tool: users upload a photo, and the tool generates a 3D mesh model from it. The official site explains that Sculptly sends only one image to the model—a second photo will not be read—so it is not a photogrammetry (multi-photo reconstruction) tool. After any purchase, models can be downloaded in GLB format, and any single purchase removes the attribution requirement from all models in your account (including already-generated ones). Two limitations to know before use. First, the side of the photo the camera did not capture is not observed—it is inferred by the model: it may look plausible, but it is not the real shape; after comparing results with real scans, users have reported that the model generates geometry out of thin air on invisible sides and deviates from the real object. Second, the official comparison page notes that meshes from this kind of single-photo reconstruction are often non-manifold and may have open boundaries, so slicers may reject STL files that look fine on screen; for uses that require precise fit with real objects or production, you should not rely on these results.
