Geeetech (HK GETECH Co., Limited, with its office at Shenzhen Getech Technology) is a Chinese 3D printer and filament maker that says it has worked on 3D printers since 2011. It made a long line of budget printers, from Prusa i3 kits through the A10/A20/A30, Mizar and Thunder series, and now sells the compact M1 and M1S for children and beginners alongside a large filament range.

Founded: 2011 · Headquarters: Shenzhen, China (company registered in Hong Kong) · Ownership: HK GETECH Co., Limited; China office Shenzhen Getech Technology Co., Ltd · Website: www.geeetech.com

Mostly open, with a caveat: the older printers came with published Marlin source and schematics, while the current M1 line has closed firmware but still runs locally with any filament and open slicers.

Firmware and custom firmware
●●●●●		 Geeetech published Marlin-based firmware source and board schematics for its earlier printers on GitHub (Geeetech3D) and its download centre, including open-source files for the Mizar S updated until 2024. For the current M1 and M1S it offers firmware binaries only; we found no source. [11][12][9][7]
Local control and integrations
●●●●●		 The M1 Mini prints from a TF card or over USB with no account. The M1S adds Wi-Fi and the Geeetech app for printing from its model library 'anywhere', a remote feature that runs through Geeetech's app. Geeetech documents no network interface for other software, and for these models it offers only firmware binaries. [4][5][8]
Third-party filament, slicers and parts
●●●●●		 Any 1.75 mm filament (PLA and TPU on the M1), and Geeetech publishes Cura and OrcaSlicer profiles for it. Nozzles and hot-end parts for the M1 are Geeetech's own, sold in its store. [4][7][10]
Repairs and spare parts
●●●●●		 Geeetech sells M1 parts (hotbed, nozzles, hot-end components, PEI plate) and posts videos on replacing the nozzle and the motherboard; schematics for older boards are published. [10][7][9]
Community and documentation
●●●●●		 A long-running wiki, a download centre with manuals, firmware, profiles and videos per model, and GitHub repositories. Independent coverage of the current M1 line is scarce. [13][6][11]
Pros
  • Inexpensive compact printers aimed at children and beginners.
  • Any 1.75 mm filament, with Cura and OrcaSlicer profiles published.
  • Spare nozzles, hotbeds and hot-end parts for the M1, plus repair videos.
  • Downloads (manuals, firmware) kept online for printers going back many years.
Cons
  • No published firmware source for the current M1 and M1S.
  • The M1S's remote printing runs through Geeetech's phone app; we found no privacy terms covering the app.
  • Small 100 x 110 x 100 mm build volume on the M1.
  • Little independent testing of the current models that we could find.
