Unofficial Matter3D Printer Stress Test Cube
Think your printer is dialed in? Let’s find out.
This unofficial Matter3D stress-test cube is designed to push an FDM printer through a concentrated mix of challenging geometry. Expect overhangs, bridges, narrow openings, sharp transitions, fine details, corners, and large surfaces—all packed into one compact print.
It’s useful for testing:
Cooling and overhang performance
Bridging
Retraction and stringing
Dimensional accuracy
Corner quality and ringing
Layer consistency
Top-surface finish
Overall filament and profile tuning
Print it with your usual profile first and see where your setup struggles. Then adjust one setting at a time and print it again—the cube makes a fun benchmark for comparing printers, materials, speeds, temperatures, and cooling profiles.
Printing recommendations
Print in the supplied orientation
No supports—the unsupported features are part of the test
Use your normal layer height and baseline material profile
Avoid slowing everything down on the first attempt
Record your filament, temperature, speed, layer height, and printer so results can be compared
For the full challenge, print it exactly as you would any normal model. No special treatment!
Share your results
Post a Make and include your printer, filament, settings, and the areas that gave your machine the most trouble. Clean successes and spectacular failures are equally welcome.
