This model was generated by PrintPal from the image beside it. Spin it and compare the full-color version with the plain STL a single-color printer gets.
Input: cottage.png, 1024 pxA busy desk diorama, with a spotted cap, door, lantern and pebbles on a grass base, still came out as a single printable body.

Each example is one AI-generated 1024 px PNG run through PrintPal's full-color image-to-3D at high detail, with no editing afterwards. Mesh checks were run on the raw download with trimesh. The preview is simplified to about 60,000 triangles so it loads fast; your download keeps full detail.
Before you start
Drawings are harder than photos for image-to-3D, because there is no lighting to read depth from: a line drawing is only outlines. The AI leans on what it knows about the subject, a dog, a robot, a dragon, to give it volume, which is why recognizable subjects convert better than abstract doodles.
Two things help a lot: color the drawing in with solid fills, and draw the subject from a slight angle rather than perfectly flat-on. If the first result drifts from the drawing, generate again or step up to Refined quality; on Pro, AI edits let you say "make the ears bigger" instead of starting over.

How to turn a drawing into a 3D model
-
1
Photograph or scan the drawing
Flat and square to the camera, in even light, with no shadow from your phone.
-
2
Upload it and sign in
Free account; the drawing comes with you.
-
3
Generate
Try two or three times; each run interprets the drawing a little differently.
-
4
Print it
Download STL, scale it to 60 to 100 mm and add a base if it needs to stand.
Tips before you print
Shoot it flat
Hold the phone parallel to the paper so the drawing is not keystoned, and crop to the drawing.
Fill with color
Solid colored areas give the AI shapes to work with. Pencil outlines alone come out vaguer.
Thicken thin parts
Stick legs and thin tails break when printed. Draw them chunkier, or thicken them in the model.
Plan a base
Figures from drawings often lean. On Pro, ask the AI to "add a round base", or glue the print to a coin.
From a phone photo to a printed object
Casual photos, not studio shots. Each one was generated on PrintPal and printed on a desktop printer.
