The cost of the first (master) compared to the resin , was what I was looking at. I know that the rubber does not last for long , I just do not know how many parts can be poured before it is junk.
I also did not know that the warping was still a problem( I worked with SLA bottle models in 96) with the SLA printed parts. I was thinking that it would be closer to the same price for the printed part, thanks for the wake up call. So much for the parts getting cheaper the longer it is open to the public LOL .
I know how all the casting works but never made more than a few parts that way at work before. The most we ever did was 20 to 25 of the same part.
