Creating Stunning Lithophanes with 3D Printing Techniques
Written on
Chapter 1: Introduction to Lithophanes
Lithophanes are captivating elements that can enhance your home decor or serve as thoughtful gifts for loved ones. These delicate creations, typically made from white PLA, reveal their beauty when illuminated from behind. The varying thickness of the material generates light and shadow effects that create stunning visual representations.
To craft your own lithophane, you'll need just two essentials: a 3D printer and white PLA filament. I recommend using the filament from Geetech for optimal results.
Section 1.1: Choosing the Right Image
The first step is selecting an image that will work well as a lithophane. Not all images are suitable; factors such as brightness, contrast, and color play a crucial role. Aim for high-contrast images with defined lines and edges. For instance, a person dressed in light colors against a white background may not be recognizable.
To guide you through the process, I'll demonstrate how to create a lithophane using the following image.

Subsection 1.1.1: Converting Your Image to STL
For this example, I recommend the Outer Curve shape, as it can stand alone and is suitable for vertical printing.
Section 1.2: Customizing Lithophane Settings
In the Settings section, you can modify essential properties of your lithophane:
- Maximum Size (MM): Defines the longest side of your model.
- Thickness (MM): Adjusting the thickness affects brightness and detail; thicker layers allow for more contrast but can obscure details in darker images.
- Border (MM): Adding a border can enhance the visual appeal.
- Thinnest Layer (MM): Determines how thin the image can be at its most delicate points to allow light to pass through.
- Vectors per pixel: This affects the quality of the image; a higher value creates smoother transitions. I typically set this to 4 for my FDM prints.
- Base/Stand Depth: Provides a base for the lithophane, though it may be unnecessary for the Outer Curve model.
- Curve: Relevant for flat lithophanes, allowing for custom diffraction settings.
After finalizing your settings, refresh the model preview and download the STL file.
Chapter 2: Preparing for Print
In this video, you’ll find a beginner's guide to creating lithophanes, complete with tips and tricks to enhance your experience.
To convert your STL file into GCODE, you'll use a software like Cura. Since each printer is unique, I can only share the parameters I used:
- Layer Height: 0.16 mm
- Outer Walls: 10
- Infill: 100%
Printing speed may vary by printer, but slower speeds generally yield better results for lithophanes, which require high precision.
Now, let’s print the lithophane using white PLA filament from Geetech.
The second video provides a comprehensive beginner's guide to creating 3D printed lithophanes, perfect for those just starting out.
Result and Conclusion
As your lithophane prints, you’ll notice the unique characteristic that emerges when backlit. Gradually, the final image will come to life.
I hope you found this tutorial enjoyable and inspiring for creating your own lithophanes.
