(Collection Care) A Workflow for 3D Modeling and CNC Cutting Object Mounts from Polyethylene Foam (10:50-11:00am)

Sometimes an object is difficult to mount (skulls) or so fragile that handling for mount-making can pose an unacceptable risk (cartonnage). Non-contact methods such as photogrammetry, laser scanning, or CT scanning can be used to make three-dimensional (3D) computer models without damaging the object, and then these models can be used as a starting point for programming robot cutting tools such as Computer Numerical Control (CNC) machines to cut exactly-fitting mounts from polyethylene foam. In this short presentation I describe a workflow used at The Field Museum in Chicago for machine cutting polyethylene foam storage and display mounts from 3D object files.
