SculptOK

Our verdict

Upload a photo or drawing and SculptOK's AI returns a grayscale depth map, with separate models for color photos, portraits and line art. A built-in lithophane and relief generator turns that map into an STL or OBJ with real settings for width, thickness, base, frames and text, and the same map works for laser 3D engraving and CNC carving. The free credits cover only a handful of watermark-free HD downloads, so regular use means a subscription, and portraits can still need touch-up.
