Ultra-fast laser-patterning computation for advanced manufacturing of powdered materials exploiting knowledge-based heat-kernels

The processing of powdered materials by laser processing has become quite widespread. One approach is to deposit a powder bed of material and to “flash” a pattern onto the bed in order to sufficiently heat up the material to sinter and/or fully melt the desired targeted pattern. This avoids rastering a single beam back and forth to produce the pattern. In order to adequately control the thermal fields that are induced by the laser pattern,simulation tools are needed to quickly ascertain the parameter setting needed, such as
