There are plenty of interesting 3D printers available on the market these days. Not all of them have an impressive build volume though. The HotRod Henry Supercharged 3D Printer is different. It is a fast, accurate FFF/FDM with 50 microns layer resolution. It can print at speeds up to 450 mm/s.
This 3D printer has a max print volume of 350x350x600mm. The companion software has an augmented reality mode that lets you see your print before you even start. The machine has a touchscreen interface and prints a wide variety of materials. You can find it on Kickstarter.
