Лазерная модификация спеченных дисперсных порошков на основе железа

Abstract

The use of laser systems in the manufacture of complex geometric form is more and more popular. This happens because of the rapid prototyping systems such as selective laser sintering (SLS), drect laser metal sintering (DI.MS), selective laser melting (Sl.M), that allow not only the production of parts with complex geometric form, hut also to fast, cheap and effective restoration of damaged places of the pans. Despite the many advantages of the above mentioned technologies, details obtained on the basis of these technologies are characterized by different defects The laser beam main modes changing influence on the parts built by SLS was studied in the paper.
