Snapmaker is a Shenzhen company founded in 2016, built around machines that swap tool heads; its Original, 2.0 and U1 machines were launched on Kickstarter. It sells the U1, a CoreXY printer with four tool heads that change in about five seconds for multi-colour printing, and the Artisan, which combines 3D printing, laser engraving and CNC carving. Its buyers are makers, hobbyists and small workshops.

Founded: 2016 · Headquarters: Shenzhen, China · Ownership: Shenzhen Snapmaker Technologies Co., Ltd.; its main products were crowdfunded on Kickstarter · Website: www.snapmaker.com

Snapmaker is mostly open: the U1 runs Klipper with a local Fluidd interface and published source, and nearly every part is sold separately. Its proprietary hotends and RFID system are the closed parts.

Firmware and custom firmware
●●●●●		 The U1 runs modified Klipper, Moonraker and Fluidd. Snapmaker published its changes on GitHub under GPL-3.0 on 30 March 2026, about three months after Kickstarter deliveries finished. Firmware for the Snapmaker 2.0 and, since August 2026, the Artisan controller is also on GitHub under GPL. [1][2][3][4]
Local control and integrations
●●●●●		 The U1 runs Klipper, Moonraker and Fluidd on the printer and prints from Snapmaker Orca over Wi-Fi or from a USB drive, so other software can use Moonraker's documented API; Snapmaker publishes its Moonraker changes on GitHub. For the Artisan, Snapmaker documents its G-code commands and has Luban pass jobs from OrcaSlicer over the OctoPrint protocol. The Snapmaker app is for remote monitoring. [1][5][13][14][15]
Third-party filament, slicers and parts
●●●●●		 Third-party 1.75 mm filament works and the U1 is supported in OrcaSlicer, but its RFID filament recognition is proprietary and only reads Snapmaker spools, and its hotends are proprietary one-piece units. Snapmaker documents using Cura, OrcaSlicer and PrusaSlicer with its older machines. [1][6][7]
Repairs and spare parts
●●●●●		 Snapmaker's shop sells most U1 parts on their own, including the main board, heated bed, extruder motor, toolhead board, belts, fans and touchscreen, and its wiki has replacement guides such as the U1 XY motor. Hotends can only be replaced as a whole unit. [8][9][1]
Data and privacy
●●●●●		 Cloud features need a Snapmaker account. The privacy policy says personal data is stored on servers in the United States, may be shared with affiliates and third parties in China for some functions, and some data is kept for three years. [10]
Community and documentation
●●●●●		 Active forum and a wiki with detailed FAQs and guides, firmware and slicer sources on GitHub, and frequent public updates and livestreams during the U1 campaign. [1][2][11]
Pros
  • The U1's four-head tool changer wastes little filament on colour changes.
  • Klipper-based U1 with a local Fluidd interface and published firmware source.
  • Nearly every U1 part is sold separately, with replacement guides.
  • Has delivered all of its Kickstarter campaigns, the U1 ahead of schedule by its own account.
Cons
  • U1 hotends are proprietary one-piece units.
  • RFID filament recognition is proprietary and only works with Snapmaker spools.
  • U1 firmware source came after deliveries, at the end of a self-set deadline.
  • Personal data is stored in the US and may be shared with affiliates in China.
  • The U1 does not work with Luban, so owners of older machines need a different slicer.
Track record
  • August 2026: Snapmaker published the Artisan's Marlin-based controller firmware on GitHub under GPL-3.0. [4]
  • March 30, 2026: Snapmaker published its modified Klipper, Moonraker and Fluidd for the U1 on GitHub under GPL-3.0, on the last day of the deadline it had set itself. [1][2]
  • December 2025: Snapmaker says all U1 Kickstarter orders shipped by 23 December 2025, ahead of its schedule. It says it delivered all three of its Kickstarter campaigns. [12]
  • September 2025: The U1 Kickstarter raised $20.2 million from more than 20,000 backers by 30 September 2025, the most for any 3D printer on the platform. Snapmaker gives the final total as $20.6 million from 20,680 backers. [11][12]
