text:  And once we find a part, we can do a 3D scan of it. We build a little bit more material than it needs so that we can end up printing it. And then we have to do a heat treatment process and then ultimately we machine it down to exactly what we want. Something I was very interested in, like not only can we do 3D plastic printing, which has been a hot topic lately, but just the fact that we can do a bunch of 3D metal printing in order to build parts is super useful.
