The additive manufacturing industry is in a stage of constantly developing new ways to make parts additively. Here is one of the more recent innovations:
The ability to 3D print single micron resolution parts in mass quantities was a challenge until recently. Thanks to several technical innovations, however, it is now possible. The innovations that were needed came in hardware, software, and materials.
Nanofabrica is a developer of micro additive manufacturing platforms. The hardware the company uses consists of a digital light processor (DLP) but with adaptive optics. Once the image to be printed is projected through the DLP, the light then passes through the adaptive optics module. The optics module electronically controls focus, tilt, and astigmatism.
