Abstract
Selective Laser Sintering (SLS) is close to be accepted as a production technique (Additive Manufacturing). However, one problem limiting employment of SLS for additive manufacturing in a wide-ranging industrial scope is the narrow variety of applicable polymers.In the present work, a thermoplastic semi-crystalline polyimide powder was synthesized.. The shape, size and fractional composition of such powder were investigated by scanning electron microscopy. As a result, polyimide powders with a fairly narrow particle size distribution were formed. On the basis of the polyimide powder, samples were obtained in the form of films by the method of selective laser sintering (SLS). The mechanical properties of these samples were investigated depending on a laser energy density. The morphological study of the films cross-sections showed that monolithic sample having insignificant pores and irregularities in the structure was formed
