Photo to Lithophane
Drop a photo and get a printable lithophane tile. Your picture's brightness becomes the panel's thickness, so light shining through the print brings the photo back. No modeling. No guessed detail. Just your picture translated into plastic thickness.
What converts best
- Portraits and pet photos are the sweet spot: a clear subject with good contrast glows beautifully
- Wedding, baby, holiday, and family photos make good keepsake prints
- Phone photos are fine when the face or subject is easy to see
- Very dark or washed out images lose detail, so favor even lighting
What you get in the download
- A 3MF with the panel and frame as separate objects, so a multicolor printer can give the frame its own filament
- A matched STL for broad slicer support
- A short README with the settings we use: white filament, 100% infill, and a vertical print
- The file is built from your photo brightness, so the result is predictable from the image you choose
How a photo becomes a lithophane
A lithophane works because light passes through thin plastic more easily than thick plastic. Bright parts of your photo become thinner. Dark parts become thicker. When you hold the print up to a lamp or window, the thickness recreates the picture in light and shadow.
That means the source photo matters. A face with clear light across it turns into a readable panel. A photo where the subject is lost in darkness turns into a muddy print. We have printed enough of these on our own machines to know the boring rule is the useful one: pick a photo where the subject is obvious before you ever convert it.
Why we print lithophanes vertically
The download is prepared for a vertical print because the layer lines carry detail better that way. A flat print can work for a rough test, but it usually softens faces and small features. Vertical printing asks more from bed adhesion, so the README points you toward a brim, full cooling, and a calm speed.
White PLA is the safest starting filament. Colored filament tints the photo. Transparent filament often looks tempting, but it can wash out contrast because too much light gets through. For gifts and family photos, a plain white or natural spool is usually the right call.
What to check before you upload
Crop the photo so the subject fills the frame. Avoid tiny faces in a wide scene. If the photo is dark, brighten it a little before upload. If the background is busy, choose a tighter crop. The converter can map brightness into thickness, but it cannot make a hidden subject clear.
After slicing, preview the first few layers and the full height of the panel. The frame should sit around the image, and the panel should stand up in the slicer. If you want to tune further, the lithophane print settings guide goes into layer height, infill, brims, and lighting.
Free to start. A couple of free generations, and you can churn more butter pats whenever you need more. No sign in required. Files delete within 24 hours unless you opt in to keep them longer.

Lithophanes, answered
What is a lithophane?
A lithophane is a thin 3D printed panel whose thickness changes with the brightness of a photo. Hold it up to light and the photo appears in shadow and glow.
What photos make a good lithophane?
Photos with a clear subject and good contrast work best. Portraits, pets, wedding photos, baby photos, and travel photos usually print well. Very dark or very flat images lose detail.
What filament and settings should I use?
Use white or natural filament, 100% infill, and a fine layer height such as 0.12 mm or less. Print vertically for the cleanest detail.
Is this AI image generation?
No. Your photo brightness becomes panel thickness. Nothing is invented, so the print stays faithful to the picture you uploaded.
Do I get a 3MF or an STL?
Both. The download includes a 3MF with the panel and frame as separate objects, plus a matched STL for slicers that prefer it.
