Just throwing this out there as I've jumped into research on the process (far from an expert)...Ive spoken to a few Big companies that Jay Leno deals with...the average cost I've encountered is $500 per vertical inch...that is not including the length(with a general consideration a first or singular part being roughly $1000 is a good base line)...It also depends on how many parts can be run at the same time on the tray which can reduce the cost of the additional items...so total cost is fairly pricey yet as this is a fairly new process in the metal printing. Competition and time will eventually reduce the cost, but not by much as plastic printing is still not cheap, but has come down slightly.
