Emerging metallic systems for additive manufacturing : in-situ alloying and multi-metal processing in laser powder bed fusion

While significant progress has been made in understanding laser powder bed fusion (L-PBF) as well as the fabrication of various materials using this technology, there is still limited adoption in the industry. One of the key obstacles identified is the lack of materials that can truly manufacture fu...
