The team behind the seemingly gravity-defying Mataerial—a 3D printer capable of churning out designs on any surface, including a ceiling—stunned the tech community this week with its next innovation, the MX3D-Metal. Housed in an industrial robot arm, the MX3D-Metal prints in a variety of metals at a staggeringly quick rate. Though the machine prints at slower rates than its non-metal counterparts, its structures are said to be strong enough to be built upon. To compensate for different metals, the machine adjusts its temperature and pressure output. Expect to see more of the MX3D-Metal across various fields, from industrial design to architecture.
