Feature: 1. 【Multi-color Printing】The printer\u0027s 4in1 dual gear extruder modules support 2 types of printings--single color, multi-color, which will greatly enrich your 3D printing experience. You can also paint color on the 3D model in slicing software to convert it into a multi-color model. 2. 【Breaking-Resume Function】 Its smart sensor can automatically resume the printing job exactly at the same place where it has been stopped after power-off or filament breakage. This function totally drives away the hassle of repetitive and time-time consuming printing jobs caused by unexpected power outage. 3. 【New User Interface \u0026 Auto-leveling】The newly designed operation interface system greatly improves the user experience, the 4.3 inch TFT-LCD screen makes its operation clearer and simpler. With fast automatic leveling and printing size as large as 300x300x400mm (11.8x11.8x15.7in), it can print works that are applicable to various fields. 4. 【Stable and Quiet Printing】This 3D printer kit adopts a stable closed aluminum profile frame combined with the CoreXY motion structure, allowing the machine to achieve high-speed printing. In addition, the machine used ultra-silent motor drivers and silent fans, making it very quiet when working. 5. 【Quick Self-Assembly】The 3D printer is 70% pre-assembled, boasts a modular design that makes it easier to assemble, and swapping the wires in and out of the extruders a cinch.
