Four steps. One precise STL
From raw image to multi-color print, our browser-based toolkit streamlines the entire 3D printing process.
Upload Image
Select your source image. Our engine analyzes contrast and geometry to prepare the data for multi-filament 3D printing.
Configure Tool
Adjust parameters for your specific keychain, plaque, or chip. Define layers, colors, and dimensions with precision.
Generate STL
Our browser-based processor compiles your settings into a high-fidelity STL file, ready for your slicer.
Send the file to your printer. Set colors. Watch your digital image transform into a physical, multi-color object.
