>Factoring a few thousand extra dollars in engine cost is easy. Totally get your point from the rest of the comment, but we could be seeing notably more expense from this. 2015-2017 I was working in a university research lab and we had an industry partner with a metal printer. They said a piece 10 inches long and 3 inches in diameter had an all-in cost of 5-8k, depending if it was steel or titanium. I never saw a detailed breakdown of the costs they accounted for, and hope we see these manufacturing costs continue to drop. There is a lot of challenge making the powder good for 3d printing. Tons of requirements around the size and shape - not being perfectly spherical, not being too long, etc. My understanding is this leads to much of the high material cost.
