Hi, I'm Kirk.
I run Pro/E/ Creo with Pro manufacture running 2 Techno routers and one large custom built CNC.
For work I cut samples of my packaging and component parts from Expanded foam, both Expanded Polypropylene (commonly seen in automotive applications) and Expanded polystyrene(commonly seen in packaging)
I'm currently using the machine to start to learn CNC for Aluminum milling which is much less forgiving than foam.
