The Monoprice Joule 3D Printer DIY Assembly Kit is a full function, large scale 3D printer that you assemble yourself using the easy assembly and operating instructions. Assembly is a breeze with our easy to understand, step by step instructions, making this kit perfect for students and hobbyists who want to know more about how the printer works and how to maintain it properly. The large, 220 x 220 x 250 mm build area allows you to print larger objects or to print several smaller objects at the same time. The fast heating, carbon silicon glass print bed greatly improves model adhesion and the rigid, all metal frame greatly reduces vibrations, resulting in more successful prints with smoother layers. Menu navigation and operation is simpler and easier with the color 4.3" LCD touchscreen than with interfaces that buttons or knobs, like those found on many other 3D printers. Loss of power or accidentally unplugging the printer with a print in progress isn't a problem with the Joule 3D Printer. The auto resume function simply continues printing when power is restored, as if nothing had happened!
