Abstract

A pure titanium (Ti) plate was fabricated by selective laser melting (SLM) in a vacuum. Ti is attractive materials for medical, aerospace, and automotive applications, because they have properties of biocompatibility, high corrosion and erosion resistance, and mechanical resistance, but forming complicated structures is challenging due to difficulties working the material. Although some studies have reported to form pores in SLMed samples due to spattering generated by laser irradiation, and there are few reports that investigate the details of the correlation between spatter and pores. Spatter results in an insufficient input energy to the powder bed because the laser is absorbed by the spatter particles. Consequently, technology to suppress the amount of spatter for SLM processes is needed. In this study, the quantitatively evaluation method for the amount of spatter was developed with high speed video camera while the SLM processes.
