My employer participated for the first time last year and we did again today. As the machinist in the R&D Shop, my machines and capabilities were part of the tour and demonstrations. Our visitors this time numbered 12 whereas last year we had almost 30 so with today's smaller group, explaining the technology and answering questions was just that much easier.
Here's what I handed out last year; a working part printed on our 3D printer. From the feedback I received today, some of the kids lost these to their fathers once the day was over back in '12......
This year we did something that we hoped was a bit more kid-friendly and less coveted by others in the household. Our CAD Designer, Eric, came up with this ball-in-a-cube. Both the adjustable wrench from last year and the ball have our company logo on them, hidden here to protect the innocent.
Our printer is an Objet 350, uses resin and UV curing to apply accurate layers of material to create models that are amazingly precise and toleranced. Printing entire assemblies, which is what the wrench above actually is, allows for some very accurate and working components, often already assembled as taken from the machine. It's an incredible tool for the development of medical instrumentation and I continue to be impressed with the problems that it helps us sort through.
