Experimental investigation into the spatter particle behavior of maraging steel during selective laser melting

The quality of built parts by selective laser melting (SLM) relies on the comprehension phenomena that takes place during and solidification metal powder. scattering spatter particle as liquid SLM process affects layer consolidation powder bed in addition to surface part. present study is focused behavior maraging steel achieve a thorough understanding occur fusing particles are tracked using high speed imaging, effects parameters investigated. ejected from melt pool also physically chemically evaluated. results showed were classified being spherical or satellite types, according their scattered volumes; some larger than initial Most droplet formed around melted front pool; number was relatively low. roughness affected generation locations tracks particles, substrate wettability principal factor affecting behavior.
