Polyamide 12 powder thermal conductivity varies with packing density and temperature, with inter-particle bonding being the primary factor influencing its performance in laser sintering. Temperature and time exposure are the most influential factors for deteriorating polyamide powder properties in the laser sintering process, affecting the quality of produced parts.

Laser sintering of polyamide 12 powder significantly impacts the microstructure and mechanical properties of sintered parts, with particle size distribution and crystallization temperature being key parameters in porosity formation. Using different ambient conditions and pretreatment can reduce the degradation of polyamide 12 powder in selective laser melting processes, resulting in better part properties. High-temperature flow properties of polyamide 12 powder deteriorate significantly, but agglomeration is excluded in the 100-140°C range, making it safe for laser sintering applications.
