While additive manufacturing is not typically considered a mass-production technology, the reduction in the size of electronics and optics — and the accompanying shrinkage of packaging — has made AM a viable production alternative for MEMS and optics housings for small to medium batch sizes. In addition to the precision offered by micro-AM, an intelligent use of our post-processes can increase the functionality of the packaging, for example by reducing stray light in the infrared, or by having integrated electrical conductors.
