The impact of metal powder recycling on the porosity of parts produced by Selective Laser Melting
 Sůkal, Jan ; Hudák, Radovan (referee) ; Paloušek, David (advisor)
Diploma thesis deals with the influence of recycling of powder steel 1.2709 on porosity of parts processed by SLM technology. Theoretical part of this thesis gives an overview of the influence of selected process parameters of this additive technology on the porosity of manufactured parts. The presence of pores in the material is the main cause of worse mechanical properties compared to conventionally manufactured materials. Since the advantage of this technology is the possibility of wasteless production, one of the possible causes of pore formation and degradation of properties of the powder material is due to standard recycling by means of sieving to remove the contaminants generated during the construction. This paper compares the porosity of parts produced by two different machines, analyzes the possible consequences of sieving on powder properties, establishes recommendations for setting the recycling process, and compares the degree of influence of process parameters on porosity.
