4-Material Toolhead Stress Test Snapmaker U1

4-Material Validation SquareThis is a small, checkerboard square for the Snapmaker U1 designed to force all four toolheads to be used equally during a print. It’s a fast way to make sure everything is functional and leveled before you commit to something bigger. Each toolhead does the same amount of work while only using about 9 grams of filament, including the prime tower. Check for gaps, offset issues, or bleeding between the nozzles. It's a quick way to confirm your printer is production-ready. Perfect for a first-run test or a post-maintenance check before you commit to a large multi-material project.
