You want a small statue of your dog, your grandfather in his favourite chair, or the ceramic owl that broke last year. A 3D printed figurine from a photo is now a weekend project: an AI model turns the picture into a mesh, and a printer does the rest. The parts that decide whether it looks like a keepsake or a lump are the photo you start with, the base, and how thin the legs are.
This guide covers what is specific to figurines. For the general route from any photo to a print, including converting to STL and slicer basics, read how to print 3D images first.
Choose the photo for your 3D printed figurine
The model reads the outline of your subject and guesses the side it can't see. A figurine also has to stand up on its own, so you want a pose with a solid footprint.
Pets
A sitting or lying pet makes a far better figurine than one mid-run. Sitting gives you a wide, flat bottom and short, thick legs; running gives you four thin legs and a tail in the air, all of which have to be supported and can snap. Shoot from a three-quarter angle at the pet's eye level, so the model sees the face and one side. Long or fluffy fur turns into a lumpy shell, which looks fine once painted, but don't expect individual strands.
People
Use a full-body photo with the feet in frame and the arms a little away from the body. Arms pressed against the sides tend to merge into the torso. Faces are the weak point: at figurine size, a face is a few millimetres wide, and the likeness lives mostly in hair, clothes and posture. A person in a hat and a red coat reads as themselves far more than a perfect nose would.
Objects
Ornaments, toys and small sculptures are the easiest subjects, since they already stand up. Avoid glass and shiny metal; the model sees reflections instead of the surface.
- Plain background. If it's busy, cut the subject out with Remove Background.
- Soft daylight, no flash.
- Nothing cropped off: ears, tail, feet.
- Sharp focus on the edges of the subject.
Turn the photo into a 3D model
Upload the photo on the Image to 3D page. Generating spends plan credits; at the time of writing a run costs between 65 and 86 credits for the models below, and the Generate button shows the exact amount. For figurines:
- Hyper3D Rodin, with the format set to STL in Advanced, gives you a printable file without converting.
- Hunyuan 3D Pro takes extra back, left and right photos. Useful for an ornament on a turntable; hard with a pet that won't sit still for four shots. The extra views add 32 credits to its 81.
- Tripo H3.1 is the cheapest of the three, at 65 credits, for trying a few photos to see which one reads best.
Keep the textured GLB even if you print in one colour. You'll want it as a colour reference when you paint. If you need an STL from it, the free 3D model converter makes one in your browser.
Make it printable: base, scale and walls
Decide the size first
Open the STL in the STL viewer, which shows width, depth and height in millimetres and inches. Pick a real height now, because every other check depends on it. Bigger forgives thin parts but costs material fast: double the height and the volume goes up about eight times. For a first print, somewhere between a mug and a hand's height keeps the print short and the details readable.
Give it a flat base
AI models rarely come with a flat bottom. The underside is often rounded or ragged, because the photo never showed it. The quick fix is the cut tool in PrusaSlicer, Bambu Studio or OrcaSlicer: slice a few millimetres off the bottom so the figure sits flat. For a pet on four thin legs, add a round plinth in Blender and join it to the feet; the plinth also gives you somewhere to engrave a name.
Check the thin parts
Ears, tails, fingers, whiskers and ankles are where figurines break. On an FDM printer with a 0.4 mm nozzle, anything thinner than about 0.8 mm, two nozzle widths, is a gamble. Resin goes much finer: Formlabs' design specs give a minimum supported wall of 0.4 mm for the Form 2 and 0.2 mm for the Form 3, with their Clear Resin. If a part is under the limit at your chosen size, print bigger, thicken it in Blender, or accept that it might break.
Resin or FDM for figurines
| Resin | FDM (filament) | |
|---|---|---|
| Fine detail | Fur texture, facial features, small fingers | Softened; small features round off at a 0.4 mm nozzle |
| Layer lines | Hard to see | Visible, less so at 0.08 to 0.12 mm layers |
| Mess and safety | Liquid resin, gloves, ventilation, an alcohol wash and a UV cure | Little cleanup beyond removing supports |
| Big figures | Hollow it to save resin, with drain holes | Prints solid with low infill |
| Strength | Can be brittle in thin parts | Tougher, especially PLA+ or PETG |
Our recommendation: if you already own a printer, use it. A pet figurine at hand height prints well on FDM with tree supports and small layers, and the painting hides most of the lines. If you're choosing how to get it made, resin is the better medium for anything with a face, at the cost of a messier process. Read the safety sheet for the resin you buy, wear nitrile gloves, and print somewhere ventilated.
On FDM, orient the figure upright on its new flat base. Chins, bellies and outstretched arms will need supports. Tree supports (organic in PrusaSlicer) come off curved shapes with fewer scars. On resin, the usual approach is to tilt the figure so the supports land on its back or underside, away from the face.
Painting a 3D printed figurine from a photo
- Remove supports and sand the nubs. On FDM, a light sand of the most visible layer lines helps more than anything else.
- Spray a thin coat of primer. Grey shows flaws; black makes dark fur easier.
- Block in the base colours with acrylics, using the textured GLB from the generator open beside you as a reference.
- Run a darker wash over fur and folds so it settles into the recesses.
- Dry-brush a lighter shade over the raised parts. This is what makes AI-made fur lumps read as fur.
- Paint the eyes last, with the smallest brush you own. A glint of white in each eye does most of the work.
- Seal with a matte varnish.
Painting takes longer than the print. Budget an evening for a pet figure, and expect the first one to teach you more than this list can.
The short version
Pick a photo with a solid pose: a sitting pet, a full-body person with arms apart, a plain background. Only use people who agreed, never celebrities or copyrighted characters. Generate the model, set a real height in the STL viewer, cut a flat base, and check ears, tails and fingers against your printer's limits. Resin for faces and fine fur, FDM if that's what you own. Then prime, wash, dry-brush and paint the eyes last.
