SLS - Selective Laser Sintering
An additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal).
The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part.
After each cross-section is
in a few years or centuries, save under very exceptional conditions. In a relatively brief period the archaeological record is reduce to mere scraps of stone, bone, glass, metal, and earthenware. Still modern archaeology, by applying appropriate techniques and comparative methods, aided by a few lucky finds from peat-bogs, deserts, and frozen soils, is able to fill up a good deal of the gap.
