Make a curved or cylinder lithophane lamp

Wrap a photo around a full cylinder for a lamp shade or night light, or lower the arc to make a curved standing panel. Set the diameter, the height and the arc from 30 up to 360 degrees; the inside stays a smooth cylinder and the photo sits on the outside.

You can engrave or raise a name or date that wraps with the photo, preview it in 3D, and download the STL or matching lids and bases with a hole for the LED. Building and previewing are free and unlimited. Downloading the STL needs a free account, which comes with a few downloads a day; Supporters download without a daily limit.

Tips for a good print

  • Print it upright, exactly as it is modelled: a cylinder supports itself. Add a brim if a tall, thin one wobbles.
  • Use 100 % infill, a 0.10 mm layer height (0.08 mm for the finest detail), a slow speed of about 30 to 40 mm/s and the fan at 100 %. Any gap in the infill lets light leak through unevenly. The full table is in the guide.
  • Light it with a cool LED (a battery tea light or an LED puck), never a hot bulb: PLA softens at about 60 °C.

Frequently asked questions

What diameter should a cylinder lithophane be?

Choose it to fit your light: 70 to 90 mm suits a tea light or a small LED puck, and a wider shade suits a lamp fitting. Make the height about the same as the photo's proportions so faces are not stretched.

What is the difference between a curved panel and a cylinder?

Only the arc. At 360 degrees the photo goes all the way round as a closed lamp shade; at 120 or 180 degrees you get a curved panel that stands on its own.

Does a cylinder lithophane need supports?

No. Printed upright, the curved wall supports itself.

What infill and layer height should I use?

Use 100 % infill, a 0.10 mm layer height (0.08 mm for the finest detail), a slow speed of about 30 to 40 mm/s and the fan at 100 %. Any gap in the infill lets light leak through unevenly. The full table is in the guide.

Can I add a name or date?

Yes. Engraved text glows brighter than the photo; raised text looks darker. Choose the position, size and style before you preview.
