Redefine multicolor and multimaterial printing with SnapSwap. Four independent, preheated toolheads let U1 switch colors and materials in just 5 seconds[1]—without all the cutting, purging, and wastefulness of conventional systems. Meanwhile, our precision kinematic coupling and mechanical locking system deliver accurate, dependable tool changes print after print. Print faster and more efficient—time after time.

Each color or material stays loaded in its own dedicated toolhead. Instead of repeatedly unloading, reloading, and purging filament through a shared nozzle, the printer swaps one complete toolhead for another in just 5 seconds. Paired with a compact CoreXY system that drives the active toolhead at speeds of up to 500 mm/s, this direct-swap mechanism helps deliver a more efficient multicolor and multi-material printing experience.

U1 uses steel-ball kinematic couplings to guide each toolhead into the same precise position, then secures it with a mechanical lock—no extra motors required. Tested for over 1,000,000 continuous swaps with zero mechanical failures, the mechanism is built to remain accurate and dependable through long-term use.

U1 automatically calibrates the XYZ offsets between all four toolheads, keeping their relative positioning within 0.04mm. Colors, materials, and support interfaces stay precisely aligned—without repetitive manual adjustment.

Pressure Advance adjusts extrusion timing as printing speed and direction change. By compensating for pressure buildup and response delay inside the nozzle, it reduces blobs, thinning, and uneven corners—producing smoother lines and cleaner, more consistent details.

Thanks to Input Shaping, the U1 achieves clean, highly‑detailed prints even at high speeds. Paired with auto mesh bed leveling that compensates for plate unevenness, it delivers consistent first‑layer outcomes with very little manual work required.
