Convert BMP to Multicolor 3MF for 3D Printing
Convert uncompressed 24-bit and 32-bit BMP files into slice-ready multi-body 3MF archives. Perfect pixel-edge fidelity for pixel art, vintage sprites, and retro emblems.
BMP Bitmap to 3MF Slicer
Upload uncompressed BMP files. Exact pixel grid extraction retains razor-sharp retro edges, ideal for arcade sprites, crests, and engineering symbols.

Why Native .3MF Instead of Standard .STL?
Standard STL files collapse all colors into one single monochrome mesh, forcing you to spend hours manually painting triangles in your slicer. Our generator exports an open-standard 3MF archive with individual color objects and stepped Z-coordinates, giving you instant zero-effort AMS assignment.
From Your Image to a 3MF Model
Adjust your model in the browser, inspect the preview, and check the exported geometry in your slicer before printing.
Upload BMP Bitmap
Upload 24-bit RGB or 32-bit RGBA BMP images. Pixel data is processed raw with zero lossy compression.
Set Pixel Grid Extrusion
Scale pixel dimensions to your desired real-world size in millimeters and pick filament colors.
Export 3MF Package
Download the 3MF file with discrete solid geometries ready for multi-color 3D printing.
Image Processing and Model Export
Review the processing workflow and choose settings that match your artwork and printing requirements.
Lossless Pixel Grid Translation
Maps uncompressed BMP raster cells directly to 3D geometric prisms, preventing muddy smoothed corners.
Exact Palette Index Matching
Honors indexed BMP palettes and maps up to 6 distinct colors to Bambu Lab AMS filament spools.
Solid Multi-Body Architecture
Structures the 3MF archive with clean independent components instead of a single fused polygon mesh.
Z-Step Elevation Logic
Automatically staggers layer heights so different colors do not collide on the same horizontal plane.
Keyring Hole & Magnet Recess Ready
Compatible with keychain punchouts and recessed magnet cavities for wearable badges and fridge art.
Browser-Based Security
Processing runs locally in your browser with zero remote server exposure or telemetry.
Calibrated Production Parameters
Tested slicing recommendations for Bambu Lab X1C / P1S / A1, OrcaSlicer, and Prusa MMU3 systems.

How can I convert a BMP bitmap image into a 3MF 3D model?
Upload your uncompressed BMP file to ImageTo3DLab. The converter reads raw pixel matrix values, builds extruded vertical prism bodies for each discrete color tone, applies 0.4mm Z-steps to avoid coplanar collisions, and packages the model into a standard 3MF archive ready for Bambu Studio, OrcaSlicer, or PrusaSlicer.
Frequently Asked Questions
Why is BMP better than JPG for retro pixel art 3D prints?
BMP stores uncompressed raw pixels. JPG compression creates blurry gradients around sharp pixel boundaries, which forces image converters to guess edges. BMP yields 100% mathematically sharp pixel corners.
Can I print BMP sprites face down on a textured PEI plate?
Yes! Inverting the model to print face down transfers the textured PEI plate grain onto the front of your sprite, giving retro arcade art an authentic textured matte appearance.
