HOW A LITHOPHANE WORKS
A photo translated into thickness and light
A lithophane represents an image with areas of different thickness. When a suitable print is lit from behind, thinner areas let more light through and thicker areas let less through, revealing the picture.
This tool turns image brightness into a flat-backed 3D relief. It exports geometry as STL; the file does not contain the original full-color photo as a texture.

CHOOSE A GOOD PHOTO
Start with a clear subject and tonal contrast
A focused photo with recognizable shapes and a useful range of light and dark areas gives the relief a better starting point. The final appearance still depends on scale, material, printer and backlighting.
Pets
Clear eyes, facial features and a recognizable silhouette help a pet remain easy to identify in the relief.
Travel and landscapes
Look for clear shapes and separation between light and dark areas. Dense scenery and tiny details may blend together.
Black-and-white photos and illustrations
High-contrast photos and simple artwork can work well. Color photos are also accepted; the tool uses their brightness information.
FIND A PRACTICAL SETTING
What the mesh detail control changes
Detail controls how finely the source image is sampled when building the relief mesh. It is an image sampling value, not a physical measurement or printer setting.
- •Lower values create a simpler mesh and can be useful for a quick first attempt; small features may be less distinct.
- •The default value of 96 is a practical starting point for balancing sampled image information and mesh complexity.
- •Higher values sample more image variation and create denser geometry. That can increase file complexity without guaranteeing a better print.
- •The available range is 24–128. It does not specify millimeters, nozzle size, layer height or photographic resolution.
FROM DIGITAL STL TO A PHYSICAL PRINT
Prepare and check the model in your slicer
Open the downloaded STL in your preferred slicer. Set the finished size there, then review thickness, orientation, mesh integrity and print settings for your machine. Light-colored or light-transmitting materials are commonly explored for backlit displays.
This tool creates a flat lithophane relief. It does not make a lamp, frame, enclosure, curved panel or complete display assembly. Test material and lighting before a final print.
PHOTO-INSPIRED PROJECTS
Ideas for a lithophane STL
Use a photo you have the right to process as a starting point for a personal print or display. For clear results, keep the main subject easy to recognize at the intended size.
Pet keepsake or memorial
Family portrait gift
Birthday or celebration memory
Travel and landscape memento
Small desk display
Wedding or anniversary keepsake
Frames, lamps and other lighting accessories are separate projects; this tool exports the flat STL relief only.
BROWSER-BASED CONVERSION
Create the relief locally from your photo
The browser uses the photo's brightness to build the STL geometry. This workflow does not ask an AI model to invent or reinterpret the image and does not submit the photo to an AI generation provider.

자주 묻는 질문
What is a lithophane?+
A lithophane is an image represented by different material thicknesses. When a suitable print is illuminated from behind, thinner sections transmit more light and thicker sections transmit less, forming a visible picture.
How do I turn a photo into a lithophane?+
Upload a PNG, JPG or WebP image, choose the mesh detail, and generate the lithophane. Download the STL, then inspect and prepare it in your preferred 3D printing software.
Which image formats are supported?+
The workspace accepts PNG, JPG/JPEG and WebP images up to 10 MB.
Can I make a lithophane from a color photo?+
Yes. The generator uses image brightness to create relief geometry. The downloaded STL does not preserve the full-color photo as printable texture information.
What photos work best?+
A focused photo with a clear subject, recognizable details and useful light-dark contrast is a good starting point. Very blurry, dark or low-contrast images may be harder to recognize.
Can I make one from a pet photo?+
Yes. Use a clear photo with recognizable eyes and facial features, choose a detail value, and generate an STL for a keepsake or display project.
Can I use a family portrait?+
Yes. Personal portraits can be converted into thickness-based reliefs. Check that faces are clear and large enough for your planned print size.
What file will I download?+
The tool exports an STL geometry file. It contains the relief mesh, not the original full-color photo or a color texture.
Is the STL ready to print immediately?+
Not necessarily. Inspect dimensions, thickness, orientation, mesh integrity and slicer settings for your printer before printing.
Can I change the lithophane size?+
The web workspace has no physical width or height control. Scale the STL in compatible 3D software or a slicer, and check how scaling affects thickness and printability.
Can I adjust the lithophane thickness?+
The current generator calculates thickness from image brightness using a fixed conversion. It does not offer separate minimum- or maximum-thickness controls.
What does Mesh Detail do?+
It controls how finely the source image is sampled to build the mesh. The available range is 24–128 and the default is 96. It is not a millimeter dimension, nozzle size or layer height.
Does higher detail always make a better print?+
No. Higher values create denser geometry, but the visible result also depends on the photo, print size, printer, material and slicing settings.
Can I create a curved lithophane?+
No. This workflow currently creates a flat-backed relief. It does not make curved, cylindrical, spherical or lamp-wrap designs.
Can this tool make a lithophane lamp?+
The flat STL can be a starting point for a separately designed backlit display. This tool does not create a lamp, enclosure, fixture or mounting system.
Do I need a 3D printer?+
You can generate and download an STL without owning a printer. To make a physical lithophane, you will need suitable printing equipment or a print service.
Which filament should I use?+
Light-colored or translucent filament is commonly explored for backlit lithophanes. Appearance depends on material, thickness, printer and print settings.
Can I make a full-color lithophane?+
This tool creates brightness-based geometry. It does not generate color layers or components for a specialized full-color printing workflow.
Can I preview the STL in 3D?+
Yes. After generation, the workspace displays an interactive 3D mesh preview that you can rotate. Use your slicer for print preparation and detailed inspection.
Does the preview simulate backlighting?+
No. The preview shows the STL geometry and does not simulate how light passes through a physical print. Material, thickness, printer settings and light source affect the final appearance.
Is the lithophane generator free?+
Local conversion does not deduct additional credits, but tool access requires a qualifying paid Create3DOnline account with a positive credit balance.
Is my photo sent to a server?+
The conversion processes the selected photo locally in your browser and does not send it to an AI generation provider. Account access checks are handled separately.
Can I use the lithophane commercially?+
Use the STL subject to the rights you hold to the source image and applicable terms. Upload only images you own or have permission to process.
How is Image to Lithophane different from Photo to STL?+
Image to Lithophane turns image brightness into a flat-backed thickness relief for a backlit photo project. Photo to STL uses AI-based reconstruction to estimate a three-dimensional object from a picture.
Does this work on Mac and Windows?+
The browser workflow is designed for compatible modern browsers on desktop operating systems. Performance depends on your device, browser and source image.
Does AI generate the lithophane?+
No. The tool uses image brightness and local geometry processing to create the STL from your photo; it does not generate new image content with AI.
