Physical characteristics of selective laser sintering of metal—polymer powder composites

An analysis was made of selective sintering of metal-polymer powder composites by laser radiation with the wavelength 1.06 {mu}m. The optical properties of the composites were investigated and their thermal conductivities were determined. A physical model of the sintering process was developed. This...

Zusammenfassung:An analysis was made of selective sintering of metal-polymer powder composites by laser radiation with the wavelength 1.06 {mu}m. The optical properties of the composites were investigated and their thermal conductivities were determined. A physical model of the sintering process was developed. This model is capable of predicting the thickness of a monolayer as a function of the composition of the composite and of the laser processing parameters.
