RISBuild Orientation Effect on Geometric Performance of Curved-Surface 316L Stainless Steel Parts Fabricated by Selective Laser Melting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selective laser melting (SLM) is a powder bed fusion additive manufacturing technology that allows the production of high-performance metal parts with geometrically complex shapes, such as curved surface, can be used in ...
Directed Energy Deposition With Coaxial Wire-Powder Feeding: Melt Pool Temperature and Microstructure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, we developed a new additive manufacturing paradigm, coaxial wire–powder-fed directed energy deposition (CWP-DED), to enable the fabrication of metals or composites with high manufacturing flexibility and ...
Additive Manufacturing of 316L Stainless Steel by a Printing-Debinding-Sintering Method: Effects of Microstructure on Fatigue Property
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) technology has been broadly applied to the fabrication of metallic materials. However, current approaches consume either high energy or large investment that considerably elevates their entry ...
Ultrasonic Frequency Effects on the Melt Pool Formation, Porosity, and Thermal-Dependent Property of Inconel 718 Fabricated by Ultrasonic Vibration-Assisted Directed Energy Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic vibration-assisted (UV-A) directed energy deposition (DED) has become a promising technology to improve the as-built quality and mechanical performance of metal parts. Ultrasonic frequency, a critical parameter ...
Ultrasonic Vibration-Assisted Laser Engineered Net Shaping of Inconel 718 Parts: Microstructural and Mechanical Characterization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser engineered net shaping (LENS) has become a promising technology in direct manufacturing or repairing of high-performance metal parts. Investigations on LENS manufacturing of Inconel 718 (IN718) parts have been conducted ...
