Your photo *

Your photo is only used to create your STL file.

Portrait 4:5. Sharp photos with good contrast and a clear subject work best.

mm

40–300 mm. The other side follows your crop (4:5), e.g. 300 mm → 240 × 300 mm.

How it works

  1. Upload a photo and choose the crop.
  2. Set size (up to 30 cm) and thicknesses – the live preview shows the plate lit from behind.
  3. “Download STL” – ready for your slicer.

We use the same algorithm as for our Geisterlicht (Beer-Lambert transmission model, tuned for white PLA). The file contains the image plate only.

Printing tips

  • White PLA, 100 % infill, print the plate upright or flat.
  • Layer height 0.1–0.12 mm, 0.4 mm nozzle.
  • Without light you see little – the image appears when backlit.
