MATERIAL ANALYSIS OF TITANIUM ALLOY PRODUCED BY DIRECT METAL LASER SINTERING

摘要

This paper focuses on the testing of samples made by Direct Metal Laser Sintering (DMLS). This additive method is based on the continuous melting of fine layers of metal powder by laser beam. The paper focuses on the DMLS process description, analysis of the titanium alloys and experimental procedures. The experimental section is a structural comparison of the materials produced by hot forming and powder metallurgy (DMLS) using scanning electron microscopy (SEM) analysis. Results from the DMLS technology and conventional powder metallurgy are compared to show the advantages of the former technology.
