While 3D printing is well known for rapid prototyping, there is a high interest in advancing the method for lightweighting and reduction of complexity in assembly. This webinar will focus on the methods and materials for additive manufacturing beyond their current understanding and application. More popularly known as 3D printing, the distinction is that additive manufacturing is a broader term that encompasses "addition or fusion" of materials to create the object. This is in contrast to subtractive manufacturing that involves machining, lithography, or, in general, removal of material to generate the object. The advantages of additive manufacturing are described as well as the various methods currently available. Highlighting the limitations of materials and the challenges for high throughput is described. Possible applications in automotive lightweighting and high performance materials are discussed.
