the "Metal Jet" printer, which it calls the world's most advanced metal 3D printer. The printer uses one moving head to spread layers of fine metal powder, and another head to bind the powder together, building up a structure layer by layer. The metal is cured, excess powder is removed, and you end up with a solid, precise design. HP claims their 3D printer is "up to 50X" more productive than other metal 3D printers, while being more flexible and cheaper than other methods. HP will offer a metal 3D printing service in early 2019, while the printers themselves will be available "for under $399,000" in 2020.
