Two Trees (TwoTrees) is a Shenzhen maker of desktop fabrication machines, founded in 2017. It built budget 3D printers from 2018 (the Sapphire Pro and Sapphire Plus, and the Bluer) and launched the SK1, a Klipper-based CoreXY printer, at the end of 2023. By October 2026 its own stores sell CNC routers and laser engravers; the 3D printer section lists no printers, and only spare parts for the SK1 remain. Its printers were bought mostly by hobbyists who like to tinker.

Open in practice: the SK1 runs stock Klipper with no cloud, and the older printers ran Marlin. The weak spot is support rather than lock-in: Two Trees has moved on to CNC and laser machines, documentation is thin and some SK1 parts are hard to find.

Firmware i niestandardowe firmware
●●●●●		 Tom's Hardware found the SK1 runs unmodified ('vanilla') Klipper, which is open source and replaceable. For the older Sapphire printers, a GitHub account named TwoTrees-china published Marlin 2.0 source for their MKS Robin Nano board in 2020 (not updated since), and upstream Klipper ships configs for the Sapphire Pro and Sapphire Plus. [7][9][10]
Sterowanie lokalne i integracje
●●●●●		 Tom's Hardware found the SK1 runs vanilla Klipper: files and settings are reachable from a computer on the home network, files can also go by USB stick, and there is no cloud or phone app to use. Klipper's standard web stack, Moonraker, documents its API, so other software can control the printer locally. [7][16]
Filament, slicery i części innych firm
●●●●●		 Any 1.75 mm filament and any slicer (Cura and PrusaSlicer profiles come on the SK1's USB stick). But the SK1's hotend copies Bambu Lab's design with a small separate nozzle, which Tom's Hardware found hard to source. [7]
Naprawy i części zamienne
●●●●●		 Two Trees' store still sells SK1 parts: mainboard, heated bed, touchscreen, fans, PEI plate and power adapter, and it published a printable SK1 extruder kit on GitHub. Tom's Hardware found nozzles and hotends hard to find, and we found none listed in the store. [11][12][13][8][7]
Społeczność i dokumentacja
●●●●●		 Tom's Hardware called the SK1's documentation sparse. Two Trees has a wiki and a download page, now centred on its CNC and laser machines; beyond that, owners rely on upstream projects such as Klipper. [7][14][15]
Zalety
  • The SK1 runs stock Klipper: control it from a browser on your own network, with no account or cloud.
  • Open-source firmware, so the SK1 can be modified and tuned freely.
  • Common SK1 spare parts (mainboard, heated bed, touchscreen, fans) are still sold by Two Trees.
  • Works with any 1.75 mm filament and any slicer; Cura and PrusaSlicer profiles are included.
Wady
  • Two Trees no longer lists any 3D printer in its own stores; it now focuses on CNC routers and laser engravers.
  • Sparse documentation for the SK1, per Tom's Hardware.
  • The SK1's Bambu-style hotend and nozzle are hard to source.
  • Tom's Hardware found typos and wrong-language menus on the SK1 touchscreen.
Doświadczenie
  • luty 2026: By February 2026 the 3D printer page of Two Trees' US store listed no products; in October 2025 it still showed the SK1 (Internet Archive captures). In October 2026 the store sells CNC routers and lasers, plus SK1 spare parts. [5][6][4]
  • październik 2024: Two Trees published a redesigned SK1 extruder kit (filament cutter, consumable detection) on GitHub under GPL-3.0, with firmware and printable STL files. [8]
  • 2023: Two Trees introduced the SK1, its first high-speed CoreXY printer, at the end of 2023. [1]
