Top 3D Printed Lithophane Generators

Lithophanes are three-dimensional printed models that take 2D images and use the variation of material thickness along with backlight to show the detailed image through the material. The accessibility of 3D has led to the development of numerous tools for generating lithophane STL files catering to diverse user needs and printer capabilities. Below, I will go over seven top lithophane generators, each with their unique features for customization options like output quality in numerous applications, which are beneficial for anyone's workflow in this type of print.

● Output Quality: Produces quick STL files optimized for FDM printers, balancing speed and detail.

● Offline Support: Runs entirely in your browser, even without an internet connection.

Applications
 Great for quick-turnaround prints or simple projects. It’s best suited for users who want to get a lithophane ready with minimal setup and no extra software.

4. ItsLitho

Software URL: https://itslitho.com

Overview
 ItsLitho is a free, cross-platform tool with an intuitive interface and a powerful built-in image editor. It offers realistic previews, so you can see what your lithophane will look like before printing.

Technical Specifications

● Supported Model Types: Includes curved, flat, lampshade, and night light designs. Optional frames and holders are available too.

● Customization Options: Offers tools to adjust brightness, contrast, exposure, and cropping directly within the interface.

● Output Quality: Generates high-res STL files suitable for both resin and FDM printing. Includes a live model viewer for previews.

● Platform: Fully web-based—no login or account required.

Applications
 Perfect for users who want detailed image editing and accurate previews before slicing. It’s especially good for monochrome lithophanes where detail and contrast really matter.

5. Cura (Image Import Feature)

Software URL: (Built into Cura; no separate URL)

Overview
 Cura, the open-source slicer by Ultimaker, includes a basic image import feature that can convert JPEG, PNG, or BMP files into flat lithophanes. While simple, it’s useful if you want everything done within the same software you use for slicing.

Technical Specifications

● Supported Model Types: Only flat lithophanes are supported—no 3D shapes like cylinders or globes.

● Customization Options: Lets you set the max height (2.5–4 mm) and base thickness (0.3–0.8 mm). Aspect ratio is locked to the image. Some basic settings adjust contrast and edge sharpness.

● Output Quality: Creates decent-quality STL files for FDM printing, but you may need extra cleanup in software like MeshLab.

● Integration: Since it’s inside Cura, you can slice and print immediately—no need for a separate STL generator.

Applications
 Good for Cura users who want a fast, no-frills way to make flat lithophanes directly from an image.

Applications
 Best for users with Photoshop experience who want total control over image editing before exporting to a 3D modeler. Great for high-quality lithophanes with refined contrast and detail.

Feature Comparison

3D Printing Optimization

To achieve optimal lithophane quality, consider these technical parameters:

● Print Orientation: Print vertically to minimize bed wobble and enhance gradient detail, especially for FDM printers. For SLA printers, vertical orientation supports larger prints (up to 185mm x 145mm) and batch printing (up to 19 lithophanes).

● Layer Height: Use 0.1–0.12mm for FDM or 0.05mm for SLA to capture fine details. Avoid exceeding 0.2mm to prevent visible layer lines.

● Material Selection: White PLA is standard for monochrome lithophanes due to its light diffusion. CMYK filaments enable color prints but require precise calibration. For SLA, use white resin for high detail.

● Infill and Walls: Set 100% infill to ensure solidity and prevent infill patterns from affecting light transmission. In Cura, avoid infill overlap settings to maintain image clarity.

● Image Preprocessing: High-contrast, grayscale images yield better results. Use Photoshop’s editing tools or ItsLitho’s built-in editor to enhance contrast. For Cura and Lithophane.github.io, preprocess images externally for optimal detail.

● Slicing Parameters: Print at low speeds (40–60mm/s) to reduce vibrations. In Cura, select “Darker is Higher” and minimal smoothing (0–1) for sharp details. Disable infill overlap in slicers like Slic3r.

Conclusion

The 3D printed lithophane have already become a mature technology. It is a open-source technology that have many online web tools to make a image into 3D model that can be printed. The well-know 3D printer giant like Bambu Lab develop its 3D printed lithophane generator that add many new features in. As a important application filed of 3D printing, many 3D printer manufacture will integrate the 3D printed lithophane generator into its software in the future.
