Building the Future: Advances in 3-D Printing
The Joseph Priestley Society welcomes David Liu, scientist at the specialty chemicals and advanced materials company Arkema, and Kevin Turner, professor and chair of mechanical engineering and applied mechanics at the University of Pennsylvania.
The 3-D printing process builds a three-dimensional object from a computer-aided design model by adding material, such as liquid resin or powder grains being fused together, layer by layer. This process is also known as additive manufacturing. In the early 1990s, 3-D printing techniques were considered suitable only for the production of functional or aesthetic prototypes. Fast-forward 30 years, and the speed, precision, repeatability, and material range have increased to the point that 3-D printing processes are now used in commercial industrial production. One of the key advantages of 3-D printing is the ability to produce very complex shapes or geometries directly without need for a mold. Thus the technology also lends itself to mass customization, where items, such as running shoes, can be customized to an individual’s needs.
Turner will discuss advances in the basic understanding of mechanical design of materials and components made via additive manufacturing. Liu will detail some of the state-of-the-art developments in additive manufacturing for the industrial scale; he has spent the last few years developing polymeric materials specifically for this application.
