Sculptly PNG to STL

Sculptly's PNG to STL converter is for flat designs: a name keychain, a badge with lettering, a sign or a silhouette on a plain background. It does not guess depth. It finds the pixels that differ from the background, follows their edge and raises that outline into a solid of the thickness you set, so every letter keeps the shape it has in your image. A transparent PNG skips the background step and uses its alpha channel. You set the design width and thickness in millimetres, the background cut-off, and optional extras: a backing plate that keeps loose letters attached, a 4 mm hanging loop, engraved detail lines, or invert to trace the light parts. The preview builds in your browser and the image is not uploaded. A print check flags strokes that are too thin and pieces that would fall off. Downloading the STL uses credits; downloading the same design again does not. It is not meant for photos of real objects; Sculptly's image to 3D generator covers those.
