RESUME PRINTING FUNCTION - Creality Ender-3 3d printer equipped with super quiet printing designing, with smooth adjustable pulley, and if power is accidentally cut off during printing, accurate printing can be continued after power is switched on.With the power supply protection device and resume printing function, no need to worry about the accidental outage, avoiding the waste of filaments.

STABLE PRINTING ADVANCED CONFIGURATION - CNC machining of the Y-rail mounting groove to make sure precise positioning and keep the solid frame with the high-precision printing quality. And big hand twist nut makes the print platform easier to level.

MK8 TECHNOLOGY USED - The Ender 3 FDM 3D printer use the MK8 extrusion mechanism, a brand-new patented infrastructure that effectively reduces the risk of plugging and poor spillage and can print most of 3d printer filament on the market, such as 1.75MM PLA/ABS/TPU.

PARTIALLY-ASSEMBLED KIT - The lower base and all wiring completed in our factory. This kit style 3D printer comes with all tools included and is an excellent project for middle school and high school-aged students. The perfect gift to spark a lifelong love for science and engineering, and provide a deeper understanding of machinery and robotics!updated USB Port makes it more convenient.
