Image to 3D Model for 3D Printing

A photo records one side of an object. To make a 3D model from an image, an AI trained on large collections of 3D objects looks at your picture and predicts the full shape it most likely came from: the depth of the side you can see, plus the sides and back the camera never saw. What comes back is a textured mesh, a surface of triangles with the colors of your photo painted on, the same kind of file a 3D artist would hand you.

The front follows your picture closely. Everything out of view is a plausible guess, so picture to 3D model works best for objects whose back you can predict, such as figurines, toys, mascots and busts. A photo also carries no real-world size, so you choose the scale. AI 3D will cost 25 credits per model on Basic, 30 on Pro and 35 on Ultra. New accounts get 10 free credits, and plans start at $12.9 a month for 300 credits. Generation is opening soon.

You do not always need AI. If you want something to hold, stand on a shelf or play with, only a full AI model has the volume for it. If the picture itself is the point, a flat print often looks better and costs far less: a lithophane shows a portrait in full detail when a lamp shines through it, a relief turns a logo or drawing into a raised plaque, and a silhouette cuts the outline out at one thickness. Those three run in your browser, so your photo never leaves your device, and each STL costs 2 credits. Switch modes in the converter above to try the same image each way.

Download the model as STL for your slicer; paid plans also give you OBJ and GLB, which keep the color texture for Blender or a web viewer. Before slicing, check that the mesh is watertight, a closed surface with no holes or flipped faces, because a slicer can fill or drop parts of an open one. Then give it a flat base: if the underside is rounded or uneven, use your slicer's cut tool to take 1 to 2 mm off the bottom, or sit the model on a small round plinth so it has a solid footprint on the bed.

Set the size in millimeters, since the file has no real scale: 60 to 100 mm tall is a good size for a first figurine on a 0.4 mm nozzle. Parts thinner than about 0.8 mm (two nozzle widths), such as whiskers or an antenna, may not print, so thicken them or scale up. Use tree or organic supports under chins, arms and tails, and turn the model so supports land on its back rather than its face. If it is taller than your build volume or has long thin limbs, split it with the cut tool, add a flat joint or pins, and glue the parts after printing.
