Based in 2015 and situated in Shenzhen, China, Anycubic has round 1000 workers and is now probably the most fashionable 3D printer manufacturers in the marketplace, with the corporate claiming it bought greater than 3 million printers in over 120 nations.
An Anycubic spokesperson was not instantly accessible for remark when contacted by BleepingComputer earlier as we speak.
