This work reports the temperature behavior associated with formation of new metal-polymer, intermetallic, and ceramic materials by Selective Laser Sintering. Here, experimental data produced from temperature measurements for inert as well as reaction powder compositions and the combustion wave front is reported. Analysis using an analog-digital-analog computer converter allowed some control of laser movement and hence some control of the exothermal reaction — in so doing it provided near optimum conditions for forming layered 3D articles.
