The brief

Analyst view

• U1 raised $20.6M from 20,680 backers in 2025, the most-funded 3D printer on Kickstarter.
• Swaps among four separate print heads instead of purging one nozzle between colours.
• Says every U1 Kickstarter order shipped by 23 December 2025.

Technical approach

As reported

Tool changing

One head per material

The J1 (2022) had two independent extruders and the U1 (2025) four, each with its own nozzle rather than one shared one.

In-house build

Design to factory in Shenzhen
