Metal 3D Printing has been around for decades but bringing it to the desktop has been difficult. Desktop Metal Inc., a Google-backed and $97 million funded company, plans to bring 3D Printing to the office with its two-pronged printing system. DM's printers can make objects out of hundreds of different alloys including steel, aluminum, titanium and copper.
DM has developed a new technology called “microwave enhanced sintering.” The 3D printers deposit layers of metal and ceramic powders that are mixed in a soft polymer. When the part is finished printing, it goes into a furnace where heat burns off the polymer and leaves a metal part. The pieces created by Desktop Metal machines can be separated by hand, making it much easier and safer than injection molding.
The in-office DM printer will cost about $50,000, and the furnace costing around $60,000, which will all be shipping in September. The production-scale printer starts at $360,000 and will come to market in 2018.
