The objectives of this paper are to review the techniques to prepare selective laser sintering polymer powder

including mechanical crushing

direct polymerization and solution techniques. Moreover

some novel powder preparation techniques including phase separation

microfluidic device

"swelling" crushing and water dispersion. In addition

the applications of different types of polymer powders were also discussed. Furthermore

the effects of powder particle size

morphology

particle size distribution On the performance of selective laser sintering process were summarized.
