I just have some pictures of printed positive moulds on hand and thought i would share them. printed in PLA on a Prusa printer.


second layer of spray filler


sanded to 800 grid


with tooling gel coat


finished mould (made with vacuum infusion) and the first part


first part close up. Finish straight out of the mould.


Another project with the bar and the lower mould have printed to get an accurate split line exactly in the center of the bar.


this is how the first mould have is made, then the lower part is removed and a composite mould is made instead.


And a close up of the finish. getting a really smooth finish and decent dimensional accuracy is really easy even with a relatively big layer height.

I hope this helps.
Cheers, Reto
