《BUYER NOTICE》Dear buyers, it's our honor that you choose our Creality refurbished 3d printer, we need you to pay attention to some things when you use the 3D printer:1️⃣Before you turn on the machine, we would like to ask you to make sure that the power cord is tightly plugged in, this can avoid the damage of the machine. 2️⃣Before you use the machine, we would like to ask you to prioritize the machine's leveling setting to avoid causing collisions between the nozzle and the print plate. 3️⃣Before you carry out a print job, we would like to ask you to insert the filament into the machine and set the 【feed in】, then carry out the print job when everything is ready. #Do not start the print job without inserting the filament! 4️⃣As this is a refurbished product, the machine body and printing plate may have slight scratches on some parts, but this does not affect the use. If you have any product problems that affect the use of the product please contact us in time, we will be the fastest and most professional advice to help you solve the problems arising from the use of the product.Rapid Printing: The Creality K1 3D printer is built for speed, reaching up to 600mm/s and 20000mm/s² Acceleration. Reaching 200℃ in just 40 seconds. That's 12 times faster than regular Fused Deposition Modeling 3D printers. Perfect for professionals and beginnersEffortless Auto-Leveling: Achieve perfect prints effortlessly with one-tap auto-leveling and dual cooling systems. The Creality K1's innovative design, including a large drum fan and simulated wind tunnel, ensures accurate leveling. An 18W turbofan allows unsupported printing of complex structuresSolid Unibody Frame: The G-sensor and die-cast frame parts of the Creality K1 eliminate ringing, ensuring steady printing. CoreXY structure, along with an auxiliary cooling fan, adds stability and vibration resistance even at high speeds. Z-axis control reduces layer lines for smoother 0.1mm detailed printsConnected and Carefree Control: Creality K1 can print via USB drive or WiFi. Creality K1 can be controlled or monitored* remotely from Creality Print or Creality Cloud APP/WEB. Also allowed when many K1 printers are online. Once the printing is complete or abnormal, a notice will be sent to your phone or PC.
