One of the current issues with 3D printing is that it can take some time to create physical versions of large or complex designs. Nexa3D's NX1 prints objects as much as 100 times faster than competitors, with printing speeds of about a centimeter in height every minute. It uses light on a certain type of resin to speed up the process. Topping up the resin seems a simpler task than with many other printers, as the NX1 uses a cartridge system instead of a manual refill process, which should help make owners' lives a little less messy.
