Features: High- 3D printer with ±0.1mm high printing accuracy, 220 * 220 * 250mm large printing size with one-piece structure, saving space but building the world. MK-8 extruder greatly reduces plugging risk and bad extrustion; and the hotbed can reach 110℃ in about 5 minutes to meet the needs of fast heating and printing. machining of Y-rail mounting to make sure precise positioning and keep the stable frame with high- printing quality. Adopts V-Socket linear bearing system and wheel moving parts, super noiseless and smooth printing performance; big hand nut make the print platform easier to level. Safely protected power supply and resume printing function, if the machine is shut down or power failure accidentally, it can continue printing after power on. Compatible with various 1.75mm printing filaments like PLA, ABS, TPU, etc; wide applications, can be used for product structure design, modeling, architectural design, parts manufacturing, etc. If you are interested, you can make a 3D printing and goggles, provide you with a safety guarantee for your family and friends.Download link of STL file of 3D printing and goggles: https://www.cxsw3d.comuploads2020025e43ce93d0d7a.zip Specifications: Plug: / / UK/ AU(Optional) Input: AC 100-265V 50-60Hz Output: DC 24V 15A 270W Modeling Technology: FDM(Fused Deposition Modeling) Printing Size: 220 * 220 * 250mm Printing Accuracy：±0.1mm Max.
