1. Find Out the Name of Your 3D Printer
- Check the label or sticker on your printer (usually on the back or bottom).
- Look at the user manual or packaging.
- If you have access to the printer’s display or software, check the settings.
- If you’re unsure, send me a picture or description, and I might be able to help identify it.
2. Download and Install Cura
Cura is a popular slicing software used to prepare 3D models for printing. Here’s how to get it:
- Go to the Ultimaker Cura official website.
- Download the latest version for your operating system (Windows, macOS, or Linux).
- Install it by following the on-screen instructions.

3. Set Up Cura for Your 3D Printer

- Open Cura and select “Add a Printer”.
- If your printer model is listed, select it. If not, choose “Custom” and enter the specifications manually.
- Load a 3D model file (STL, OBJ, or 3MF format).
- Adjust settings like layer height, print speed, and infill.
- Click “Slice” to generate the G-code file for your printer.


4. Start Printing
- Save the G-code file to an SD card or USB (or send it directly if your printer supports Wi-Fi).
- Load the filament into the printer and ensure the bed is leveled.
- Start the print and monitor the first few layers for any issues.



How to Convert a JPG Image to STL Using Lithophane Websites
Lithophanes are 3D-printed images that reveal details when backlit. Converting a JPG (or PNG) image to an STL file allows you to create a 3D-printable lithophane. Below is a step-by-step guide to converting your image using a lithophane generator.
Step-by-Step Guide to Converting JPG to STL
Step 1: Visit a Lithophane Generator Website
There are several online tools for creating lithophanes. One of the most commonly used is Lithophane or ItsLitho . Open the website in your browser.

Step 2: Upload Your Image (JPG or PNG)
- Click on “Images” or “Upload” (depending on the website).
- Select the JPG file from your device.
- Wait for the image to load into the tool.

Step 3: Adjust Lithophane Settings
Most lithophane generators allow you to customize the shape, thickness, and resolution of the model.
- Select Shape: Choose from flat, dome, sphere, or other styles.
- Adjust Thickness: A thicker base creates more contrast.
- Set Dimensions: Adjust width, height, and depth according to your 3D printer’s capabilities.
- Preview the Lithophane: Check the model before exporting.
Step 4: Generate and Download the STL File
- Click on “Generate STL” or “Download STL” (this may take a few seconds).
- Save the STL file to your computer.
Step 5: Import into Slicing Software
To prepare the STL file for 3D printing:
- Open Cura, PrusaSlicer, or any slicer software.
- Import the STL file and adjust print settings (layer height, infill, supports, etc.).
- Slice the model and export the G-code for your 3D printer.
Step 6: Start 3D Printing
Load the G-code onto your 3D printer and begin printing. Use a light-colored filament for better contrast when backlit.
Conclusion
Converting a JPG to STL for lithophanes is easy with the right tools. By following these steps, you can turn your favorite photos into beautiful 3D-printed lithophanes that come to life when illuminated! 🚀
