New 3-D printer is 10 times faster than commercial counterparts

29.11.2017 | MIT | news.mit.edu

MIT engineers have developed a new desktop 3-D printer that performs up to 10 times faster than existing commercial counterparts. Whereas the most common printers may fabricate a few Lego-sized bricks in one hour, the new design can print similarly sized objects in just a few minutes.

The key to the team’s nimble design lies in the printer’s compact printhead, which incorporates two new, speed-enhancing components: a screw mechanism that feeds polymer material through a nozzle at high force; and a laser, built into the printhead, that rapidly heats and melts the material, enabling it to flow faster through the nozzle.

New 3D printer

The team demonstrated its new design by printing various detailed, handheld 3-D objects, including small eyeglasses frames, a bevel gear, and a miniature replica of the MIT dome — each, from start to finish, within several minutes.
