Lucas123 writes HP today announced an 3D industrial printer that it said will be half the cost of current additive manufacturing systems while also 10 times faster, enabling production parts to be built. The company also announced Sprout, a new immersive computing platform that combines a 23-in touch screen monitor and horizontal capacitive touch mat with a scanner, depth sensor, hi-res camera, and projector in a single desktop device. HP's Multi Jet Fusion printer will be offered to beta customers early next year and is expected to be generally available in 2016. The machine uses a print bar with 30,000 nozzles spraying 350 million drops a second of thermoplastic or other materials onto a print platform. The Multi Jet Fusion printer uses fused deposition modeling, an additive manufacturing technology first invented in 1990. the printer works by first laying down a layer of powder material across a build area. Then a fusing agent is selectively applied with the page-wide print bar. Then the same print bar applies a detailing agent at the parts edge to give high definition. The material is then exposed to an energy source that fuses it.
