Metaform LLCMetaform LLC grew from a failed consumer 3D printer into a small manufacturer of compact 3D-printer hotends, led by a team that set out to solve the machine’s weak extrusion. The company machines and assembles its Pico Hybrid hotend in the USA, pairing a lightweight design with a nozzle system that can switch between PTFE-lined and all-metal setups. Its manufacturing approach keeps production in-house so the team can refine the design in response to printer users.
