Absolutely agree with you guys about the costs now, however sooner or later prices will go down, and print shops will be available almost everywhere, at least initially to do some plastic parts, like a new trunion, tanks, etc.. pretty much like this guys are doing right now at a reasonable hobbyst prices.

Maybe some years from now, this will apply for metal parts for turbine engines too.
