Mine was in 1999. My parents laboratory was having a family day so we got to go and see some of the work they were doing. I don't remember much about that day but I certainly remember their 3d printer. It was a FDM printer, and I think had a stationary build platform where x and y all moved together by raising Z, though I don't remember for certain. I remember it was LOUD! Old stepper motors and what not. The coolest thing they had printed was a putter head, and I remember being super impressed by that. I believe they were printing a skull while they were there. They were handing out these little pendants for the kids. I was worried I lost mine but managed to recover it this weekend. So what are your stories?
