Snapmaker U1 3D Printer

Snapmaker U1 3D Printer: four-toolhead multi-colour printing

The Snapmaker U1 3D Printer uses four independent toolheads instead of repeatedly feeding different materials through one nozzle. Its SnapSwap™ system changes toolheads in around five seconds, making multi-colour and multi-material work quicker while greatly reducing purge waste.

A 270 × 270 × 270 mm build area gives the U1 useful capacity for detailed models, functional parts and small production work. CoreXY motion supports toolhead speeds up to 500 mm/s and acceleration up to 20,000 mm/s², while pressure advance, input shaping and automatic calibration help maintain clean surfaces and accurate first layers.

Key features

• Four independent toolheads for up to four colours or materials
• SnapSwap™ tool changes in approximately five seconds
• 270 × 270 × 270 mm build volume
• Up to 500 mm/s toolhead speed and 20,000 mm/s² acceleration
• Automatic mesh bed levelling, toolhead offset calibration and flow compensation
• Flexible textured PEI steel build plate heated up to 100°C
• Four 0.4 mm stainless-steel hotends with temperatures up to 300°C
