Title : Additive Manufacturing: Process Simulation Technology
Abstract:
Additive manufacturing (AM), also known as 3D printing, is a broadly used term to describe industrial processes by which three-dimensional objects are manufactured through: (1) A controlled deposition of powdered or liquid raw material; (2) Followed by an induced transformation into a solid state. Modern AM processes enable rapid prototyping of complex three-dimensional parts that is often not feasible using traditional manufacturing techniques. AM thus opens up new possibilities for design, technology, and innovation in many different fields of engineering and science. From a simulation point-of-view AM processes present a host of new challenges to the computational mechanics community. Predictive numerical results need to properly take into account a wide variety of challenging physics including: material transformations, rapidly moving energy sources, high temperatures, evolving surfaces, and proper convective and radiative boundary conditions. In this talk I will discuss AM and the associated simulation challenges and present some of our most recent numerical results.
