Personal 3D printing isn’t the only industry that’s getting more crowded. Huge Japanese trading company Mitsubishi will begin selling a professional-grade metal laser sintering 3D printer in North America this month, 3Ders reports. The printer is made by Matsuura and starts at roughly $850,000. Laser sintering, which uses a laser to seal together powdered particles of a material, has yet to be adapted to the desktop, meaning large, professional machines like these are the norm.
