The computer and printer giant claims that the new 3D printing technology is 10 times faster than that in existing 3D printers.
HP Multi Jet Fusion technology is built on HP's knowledge in inkjet printing, inks and jettable agents. As with many 3D printing processes, HP Multi Jet Fusion starts by laying down a thin layer of powdered material across a build area. Then, the carriage containing an HP Thermal injet array passed from left-to-right, printing chemical agents accross the full working area. The technology uses a unique multi-chemistry process, including a fusing agent that is selectively applied where the particles will fuse together, as well as a detailing agent that is selectively applied where the fusing action needs to be reduced or amplified. As one example, the detailing agent reduces fusing at the boundary to produce parts with sharp and smooth edges.
