Glowprint: 3D Lithophane Maker
Photos to STL for 3D printing
Free · In‑App Purchases
Christmas is coming: turn a photo into a glowing ornament or lamp. New in 1.1: domes stand on a base, and the iPhone layout works sideways too. First export free.
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

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

MADE FOR LIGHT
• Auto-tone spreads your photo across the full printable thickness
• Fine-tune brightness, contrast, gamma and smoothing with a live histogram

BUILT TO PRINT

• 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.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Halloween: a jack-o'-lantern, pumpkin, skull, witch's hat and black cat. The faces and eye sockets are cut right through, so the light shines out.
• Domes can now stand on a base, so they sit upright instead of tipping forward.
• Redesigned for iPhone: the model gets more of the screen, and the light and view controls stay in sight above the panels.
• Turn your iPhone sideways: the model and panels sit side by side.
• A new Projects screen: your last project at the top, Favourites and Exported filters, sorting, and a menu on every project.
• Clearer Settings: your credits first, and build sizes for 11 common printers one tap away.
• Fixes: the credit balance shows its number again, and sheets no longer run past the edges of the iPhone screen.
