Established in 2017, it sells its own large Klipper printers (T300 and T500), filament dryers and filament, and its store also resells Sovol products and, as an authorised distributor, Creality printers. The T300 is also sold in Sovol's own store.

Mixed, leaning open: Klipper printers with open filament and no cloud we could find, but no published firmware or configuration and very little documentation; support leans on the Sovol relationship.

Firmware and custom firmware
●●●●●		 The T300 and T500 run Klipper, which is open source, but we found no published firmware or configuration for them: Comgrow's GitHub organisation has no public repositories, and Sovol's Klipper fork does not name them. [3][8][7][10]
Local control and integrations
●●●●●		 The T300 and T500 run Klipper on a touchscreen; Sovol's T300 listing says it can be controlled remotely over Wi-Fi or printed from a USB drive. We found no Comgrow cloud service or account, but also no Comgrow documentation of its web interface or of Moonraker, so access for other software is unconfirmed. [8][11]
Third-party filament, slicers and parts
●●●●●		 Klipper takes G-code from any slicer, and we found no chipped spools or cartridges. Hardened nozzles are shared with Sovol printers (SV07, SV08), so parts overlap across the two brands. [5][6][11]
Repairs and spare parts
●●●●●		 Comgrow sells T300/T500 extruders, a hotend kit, nozzles, a PEI plate, the T300 screen and the T500 power supply; Sovol's store also stocks T300 parts. We found no repair guides. [5][6][8]
Community and documentation
●●●●●		 Little documentation of its own: Comgrow's site links to Sovol's wiki, which has only a store link for the T300, and we found no Comgrow forum or code. [2][9][7]
Pros
  • Large build volumes (300 mm and 500 mm cubes) on Klipper, with no cloud account we could find.
  • Shares a parent company and parts with Sovol, so nozzles and other parts overlap.
  • Spare extruders, hotends, nozzles and plates sold in Comgrow's store.
Cons
  • Very little Comgrow documentation; the site points to Sovol's wiki.
  • No published Klipper configuration or firmware for its printers that we could find.
  • Few independent reviews of the T300 and T500 from major outlets.
  • 3DJake, a large European retailer, lists the T500 as no longer sold.
