Who is it for?Multicolor and multi-material hobbyists who want a true tool changer (four separate hotends, soluble supports, TPU and PLA in one print) for well under $1,000, and tinkerers who value Klipper-based firmware they can inspect and modify.
Key strengths
- Four real toolheads, almost no purge
Each filament has its own preheated hotend, and swaps take about 5 seconds. Multicolor prints skip the purge tower and filament waste of single-nozzle switching systems.
- True multi-material printing
Separate hotends mean PLA with PVA or breakaway supports, or rigid PLA with TPU, in one print. Single-nozzle multicolor systems handle these combinations poorly.
- Open, Klipper-based platform
Snapmaker has published its Klipper, Moonraker and Fluidd forks on GitHub, and Snapmaker Orca is built on Orca Slicer. There is already an active community firmware project. RFID filament recognition stays proprietary.
The Snapmaker U1 is a CoreXY tool changer with four independent, preheated toolheads. Each color or material has its own hotend, so a swap takes about 5 seconds and there is almost no purging. That makes multicolor prints much faster and far less wasteful than single-nozzle filament-switching systems. It has a 270×270×270 mm build volume, a 500 mm/s top speed, 300°C hotends and a 100°C bed. Calibration is automatic: XYZ offsets between toolheads (to within 0.04 mm), mesh bed leveling, input shaping and pressure advance. Snapmaker launched the U1 on Kickstarter in 2025 and it went on general retail sale on 10 April 2026 at $899. The US store currently lists it at $699 for Black Friday, but the base unit was showing as unavailable there at the time of writing. The U1 has an open frame. ABS, ASA, PA and PC need the optional $149 Top Cover, and fibre-filled filaments also need hardened steel hotends. Snapmaker has published its Klipper, Moonraker and Fluidd forks on GitHub, and Snapmaker Orca is based on Orca Slicer.
