Glowprint: 3D Lithophane Maker

Turn your photos into glowing 3D prints.

A lithophane looks like a plain white carving until light shines through it. Then the thin parts glow, the thick parts stay dark, and your photo appears. Glowprint turns any photo into a lithophane for your 3D printer: a panel, a lamp, an ornament or a night light.

Choose a photo, pick a shape and watch it glow on screen before you print a single layer. When it looks right, export an STL, 3MF or OBJ file and send it to your slicer.

126 READY-MADE DESIGNS
Start from one of 18 categories, then change anything:
• Panels shaped as hearts, arches, ovals, stars, clouds and more, with stands to display them
• Lamps, lampshades, tealight lanterns and plug-in night lights
• Halloween pumpkins and skulls, Christmas ornaments, baubles and bells
• Photo globes, and box lamps with a different photo on each side

YOUR PHOTO, FRAMED RIGHT
• Take a photo, choose one from your library or open one from Files
• Crop, straighten and flip, then drag and pinch to place it in the shape
• Find the face and frame it in one tap, right on your device
• Line up several photos side by side, or put one on each side of a box lamp
• Add a name, a date or a quote in three lettering styles

MADE FOR LIGHT
• Auto-tone spreads your photo across the full printable thickness
• Fine-tune brightness, contrast, gamma and smoothing with a live histogram
• Filament presets for white PLA, grey PLA and natural PETG
• Preview it backlit, from candlelight to daylight, and move the bulb to see where it glows brightest

BUILT TO PRINT
• Every model is checked to be watertight before export
• Set your printer's bed size and nozzle, and anything too big or too thin is flagged
• Each design comes with print settings: orientation, infill, supports and brim
• See an estimated print time, triangle count and file size before you export
• Add frames, hook holes, hangers, lids, bases, stands and cable cutouts
• Exploded view shows every piece that prints on its own
• Print the frame or base in a second filament, or put a paper print behind the panel for colour
• A free thickness test strip calibrates your printer and filament
• A built-in guide explains how lithophanes print

PRIVATE BY DESIGN
No account, no server and no upload. Your photos and projects stay on your device unless you choose to share them.

SIMPLE PRICING
Designing, previewing and saving are always free, and your first export is included. After that, a project uses one credit the first time you export it. Exporting it again, in any format and after any change, is free. Credits come in packs of 1, 3 or 10 and never expire. If you print a lot, a one-time full unlock makes every export free on your iPhone, iPad and Mac. There is no subscription. A failed export costs nothing, and credits are kept in iCloud, so they follow you across your devices.

Also available for Mac.
