What Is a 3D Printed Lithophane Lamp Shade?
A lithophane is a thin 3D printed panel that reveals an image when backlit. When you place it in front of an LED light, the varying print thickness creates light and dark areas, turning a regular photograph into a glowing picture. PrintPal's free lithophane generator lets you skip the CAD work and go straight from photo to print-ready STL.
How to Create a Lithophane on PrintPal
- Open PrintPal.io and navigate to the Tools section in the main menu.
- Find the Lithophane / Lamp Shade Generator in the tool list.
- Upload your picture — JPG or PNG works best. High-contrast photos with clear subjects (portraits, pets, landscapes) produce the most striking results.
- Adjust the settings: tweak thickness, layer height, image brightness/contrast, and the negative/positive toggle to preview how the image will look when lit.
- Toggle the "Make it a stand" option if you want a built-in base so the shade sits upright on a flat surface.
- Download the STL file and send it to your slicer.
Print Settings & Material Tips
- Material: White PLA or white PETG gives the cleanest light transmission. Avoid dark or translucent filaments.
- Layer height: 0.08–0.12 mm balances detail and print time. Thinner layers reveal finer image detail.
- Infill: 100% infill is recommended for lithophanes — any internal gaps will show through and distort the image.
- Walls: At least 3–4 perimeter walls help maintain structural integrity and consistent thickness.
- Speed: Print slower than usual (40–50 mm/s) to keep layer consistency across the varying thickness of the panel.
Lighting & Display Ideas
- Drop in a warm white LED strip behind the shade for a cozy nightlight effect.
- Use addressable RGB LEDs to cycle colors and create animated photo displays.
- Print a matching base with a slot for a USB-powered LED puck light for a clean, cable-free look.
Frequently Asked Questions
Is the PrintPal lithophane generator free?
Yes. The tool is free to use with no account required for basic generation.
What image format should I upload?
JPG and PNG are supported. Use the highest resolution available for sharper detail.
Can I use the lamp shade with any 3D printer?
Yes. The downloaded STL works with FDM printers that have at least a 180 x 180 mm build plate for standard shades.
Do I need supports?
Most lithophane lamp shades are designed to print without supports thanks to their gentle overhangs.
