Seen it and very impressed, thats where the idea started. I always thought the mold material needed to be metal. The problem is those 3d printers cost a fortune to buy and run. That mold likely cost more than a £1000 just to print and I doubt it will last more than a few cycles. Still very exciting tech in time I guess the cost will come down.

its not a bad idea,there are high temp tooling resins out there ,used in injection moulding, dies etc,im not sure how such a mould would fair with long term use but for the right job and concidering the prices some firms want for tooling,id consider it

When you say terrible do you mean because of the surface finish?
Cheers.
