After seeing the printer in action, We have came away impressed. As many of you know the printer does not operate the same as other 3D printers. Most printers an extruder that will run on X,Y,Z axes, in the same typical way. However, the Orion Delta is a bit different. It has 3 vertical bars which have 3 robotic arms attached. They more in unison to print in the correct areas. The build sizes of these printers are huge relative to the smaller size of the printers.
