That's what plate swappers like these use: they take the finished plate off and slide a fresh one on. Without a kit, a G-code routine can push cooled prints off with the toolhead. For example: [JobOx](https://simplyprint.io/features/autoprint/jobox), [swapmod](https://simplyprint.io/features/autoprint/swapmod). ### Ways to automate it - [Push prints off with the toolhead](https://simplyprint.io/features/autoprint/push-off): On a bed slinger, a G-code routine can sweep the cooled print off the bed before the next job starts. - [Your own ejection G-code](https://simplyprint.io/features/autoprint/custom): Write the routine that clears your plate, and AutoPrint runs it after every print. - [A robot arm, or anything with an API](https://simplyprint.io/features/autoprint/api): Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system. - [Clear it by hand, keep the queue](https://simplyprint.io/features/autoprint/manual-mode): AutoPrint waits for you to mark the plate clear, then starts the next job. [How AutoPrint works](https://simplyprint.io/features/autoprint). AutoPrint comes with the Pro plan and up. ## Two Trees Bluer Plus specifications: bed size, print height and more ### Size - Build volume: 300 x 300 x 400 mm - Bed type: Square - Bed size: 300 x 300 mm - Max print height: 400 mm ### Printing - Motion system: Bed slinger - Max extruder temperature: 260 °C - Has heated bed: Yes - Max bed temperature: 100 °C - Number of nozzles: 1 - Toolheads: 1 - Direct drive: No - Probing tool / Auto Bed Leveling: Yes - Filament width: 1.75 mm ### Multi-material - Toolchanger or hotend changer: No - IDEX (independent dual extruders): No ### Connecting - Connectivity: SD card, USB - Supports serial printing: Yes - Shipped firmware: Marlin ### Files and slicing - Supported file formats: G-code (.gcode, .gco, .g) ### The printer - Printer manufacturer / brand: Two Trees - Printer model name: Bluer Plus - Made by a company from: China - Launched: January 2021 ## What filament can the Two Trees Bluer Plus print? Filament compatibility for the Two Trees Bluer Plus: the materials it can handle, judged from its hotend, bed, chamber and enclosure. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. | | PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). | | TPU & flexibles | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. | | ABS & ASA | With care | The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints. | | Nylon (PA) | With care | Possible with care - an enclosure and very dry filament are essential. | | Polycarbonate (PC) | Not ideal | Not recommended - PC needs very high hotend temps and an enclosed chamber. | | Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. | ### Best filament for the Two Trees Bluer Plus Filaments the Two Trees Bluer Plus prints well, Two Trees's own first, then the best known. - [Bambu Lab PLA Basic](https://simplyprint.io/filaments/bambu-lab/pla-basic): PLA, 190-230 °C - [Bambu Lab PLA Matte](https://simplyprint.io/filaments/bambu-lab/pla-matte): PLA, 190-230 °C - [SUNLU PLA](https://simplyprint.io/filaments/sunlu/pla): PLA, 190-230 °C - [Anycubic PETG](https://simplyprint.io/filaments/anycubic/petg): PETG, 230-250 °C - [Anycubic PLA Basic](https://simplyprint.io/filaments/anycubic/pla-basic): PLA, 190-230 °C - [Anycubic PLA Plus](https://simplyprint.io/filaments/anycubic/pla-plus): PLA, 190-230 °C - [Bambu Lab PETG Basic](https://simplyprint.io/filaments/bambu-lab/petg-basic): PETG, 230-260 °C - [Bambu Lab PETG HF](https://simplyprint.io/filaments/bambu-lab/petg-hf): PETG, 230-260 °C ## Compare the Two Trees Bluer Plus with similar printers - [Two Trees Sapphire Plus](https://simplyprint.io/compatibility/two-trees-sapphire-plus): Compatible, 300 x 300 x 330 mm, Also by Two Trees · Similar build volume - [Creality K1 Max](https://simplyprint.io/compatibility/creality-k1-max): Compatible, 300 x 300 x 300 mm, Similar build volume - [Prusa XL](https://simplyprint.io/compatibility/prusa-xl): Compatible, 360 x 360 x 360 mm, Similar build volume - [Sovol SV06 Plus](https://simplyprint.io/compatibility/sovol-sv06-plus): Compatible, 300 x 300 x 340 mm, Similar build volume - [Compare the Two Trees Bluer Plus with other printers](https://simplyprint.io/compatibility/compare?compare=two-trees-bluer-plus#choose) ## About Two Trees 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. - Founded: 2017 - Headquarters: Shenzhen, China - Ownership: Parent company: Shenzhen TwoTrees Holdings Co., Ltd. - Website: https://twotrees3d.com Openness: Mostly open (3.9 of 5) 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 and custom firmware (4 of 5): 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. - Local control and integrations (5 of 5): 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. - Third-party filament, slicers and parts (3 of 5): 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. - Repairs and spare parts (3 of 5): 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. - Community and documentation (2 of 5): 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. ### Pros - 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. ### Cons - 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. ### Track record - February 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. - October 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. - 2023: Two Trees introduced the SK1, its first high-speed CoreXY printer, at the end of 2023.
