【摘要】 The use of Additive manufacturing (AM) processes is growing across the manufacturing landscape and continues to gain more traction in the aerospace sector, where it is helping reduce weight, lower carbon emissions, cut costs and overcome supply chain challenges. One of the early adopters of additive manufacturing (AM) to manufacture parts was aerospace and it is still on the rise among manufacturers, as industry leaders use more composite and metal additively manufactured parts, which can provide lighter and stronger parts, and other benefits.

【摘要】 Advances in additive manufacturing are moving the technology in the direction of making production-ready parts. But before investing in 3D printing, take some time to understand the different types of equipment and materials. Once a novelty technology used by a few cutting-edge companies to make part prototypes, 3D printing, also known as additive manufacturing, is now considered a mainstream technology for the factory floor. A good fit for automotive, aerospace, and medical industries, 3D printing is also the perfect fit for customized work. 3D printing's early value proposition has always been its ability to shorten production development cycles, with designers and engineers using 3D printing to produce quick-turn prototypes. The technology and materials then evolved to take 3D-printed prototypes and use them in a functioning manner for testing. Now the industry is moving 3D printing into a production support role, leveraging the printers to make jigs, fixtures, or end of arm tools customized for a particular work process.

【摘要】 Multilayer deposits of 2319 aluminum alloy were made using the Tungsten Inert Gas (TIG) welding-based Wire Arc Additive Manufacturing (WAAM) technique. The effect of interlayer time interval (ITI) on deposits' microstructure and mechanical behavior is investigated. The microstructure of the ten-layer (all regions), twenty-layer (top), and forty-layer (top) deposits show that there are grains that are all equiaxed. But the middle and bottom parts of the twenty-and-forty-layered deposits comprised both columnar and equiaxed grains. The strength of the twenty-layer deposits with two- and five-minute interlayer time intervals are 217±5 and 237±5 MPa, respectively. In contrast, the forty-layer deposits recorded strengths of 247±5 and 258±5MPa, respectively. Therefore, the twenty- and forty-layered deposits fabricated at 5 min interlayer time intervals recorded better tensile properties.
