Super Fast SLA 3D Printer

This video is already a year old, but the technology is still young. SLA means Stereo Litographic Apparatus, a 3D printer that lifts UV-hardened plastic out of a resin bath. While common SLA is known since the 1980ies and was very expensive for the duration of the patent, and slow, because they used a UV laser hardening point after point, a company called Carbon (or, Carbon3D Inc) created a process where they use a DLP projector as used in beamers to project an entire plane at a time, accelerating the process so much it could be used in mass manufacture.

Plus, they offer a range of resins, resulting in different mechanical properties including flexible materials. The important advantage is that a designer traditionally prototypes with a 3D printer but must consider that mass production uses injection molding; limiting the range of geometries he can use in his design – this limitation is removed when mass production uses 3D printing as well.

The company already has a collaboration with BMW to explore use of their technology in mass production.
