Doesn't your lab needs some new equipment? https://www.youtube.com/watch?v=Z8MaVaqNr3U

Looks like that could be a really great way to get some of the unobtainium parts for our cars re-created. Several years back there was an article about (Jay Leno maybe) getting new heads made up for the Dusenbergs. The castings cost ~$40,000 each, and it seems that our skill in casting has gone down from the master craftsman on early generations. This kind of technology could make re-creating these parts much more reasonable

Neat, but I prefer what this guy is doing.

Our older 3D printer works like Billy's link. Only prints a plaster/glue mix but places it in a similar "sandbox" that you pull it out of after the print is completed. Kind of a neat idea but the machine is service-intensive and the company (Z-Corp) provides such poor service that we gave up on it. We just bought 3 new Makerbot Replicators (which use a somewhat different 3D printing method....with ABS only) for about half of what we paid for the one Z-Corp unit. We already have an older Makerbot. Parts and service are great. If you look on Thingiverse, you'll see lots of folks using their Makerbots to create simple, plastic car parts. ~HERE~ (https://www.thingiverse.com/thing:20028) is an example. I've done the old-time aluminum sand casting like Walt's video.....we did it almost every day when I was a high school metal shop teacher.

Hey Nial, I still have my cast piece for H.S. I think it was a flintlock pistol?

We may have had the same machine, we didn't use ours either. Glad to know you have casting experience, I'm starting to get set up now. I made up a bunch of redneck greensand from the creek bank and old clay pit. Red clay is everywhere, I wanted to see if I could use what was on hand. It rammed up nice, still needs a little work but overall I'm pleased. There's a German guy on youtube casting small water cooled heads in his garage. https://www.youtube.com/watch?v=_M0DxxlIK3I

Hey Nial, I still have my cast piece for H.S. I think it was a flintlock pistol?( LOL! (For other who may not realize, George was in my class back then). Actually, I have a cast piece that I made when I was a freshman in college. It's an ashtray and my family uses it as the "trophy" every year for our summer batting completion. Right now my brother's neighbour has it.
