On-Site Speaker (Planned) Jason Walker
Abstract Scope Additive Manufacturing stands to transform sand casting as binder jetting can be used to create sand molds with unprecedented geometric complexity as well as with the inclusion of sensing capabilities. With printed sand molds, castings can be optimized in terms of the strength-versus-weight trade off. However, with an increase in design complexity comes a dramatic increase in complexity in terms of both the thermodynamics and chemistry of the casting process. One potential solution is to leverage the design freedom of CAD-based solid modeling to introduce cavities specifically for inserting sensors (Internet of Things) to enable the collection of a diversity of data on the casting. This presentation will discuss preliminary data from unprecedented levels of sensing and process monitoring through both wireless and wired sensors placed at strategic locations throughout a printed mold and potentially inside internal cores. Challenges include sensor survivability versus disposability and discrepancies between sensing and simulation.
