Group: Forum Members Posts: 74, Visits: 1.8K	Hello friends, I was studying making 3D impression moulds and sealing with epoxy resin to make carbon fiber parts in the Wet Layup + Vacuum Bagging or Vacuum infusion process. Has anyone done any 3D impression mould? What better material for printing? The composites will be cured at room temperature. Thanks!

How can i suppress the rising of curing resin temperature in order to avoid such a possibility ? Yes, entirely possible but depends on the resin system and layer thickness. I make most of my molds with vacuum infusion and with those slow resins it is typically not an issue even for a very sturdy mould. Otherwise you can always laminate in two goes or when hand laminating just wait a little in-between resin batches

ive done plenty of 3d printed tooling, if you are doing room temp wet lay then you can get away with PLA printed materials but you need to make sure they are properly sealed and released as Epoxy...

Thanks Scottracing, As it will be cured by ambient temperature the conventional materials will supply my needs well. Do you have any pictures of a 3D printed mould ? Thankful.

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....

This will help me a lot, for sure! Many thanks friend!

Hello! This looks very promising. I know it is old post but did not wanted to make new. Lester, can you comment on the finishing layers after 3D printed mold with filler is sanded? I suggest there....

what layer height did you use on the PLA print? And did you sand it prior to the first coat of primer? The finished part looks brilliant, is that a flax/hemp material you made the part from?

scottracing - 7 Years Ago

I usually print with a Layer height of 0.15 to 0.2mm and give it a light sand to get rid of small bumps where a new layer started and any things like that. Then usually two coats of heavy filler and....

0.15 layer height !!!! How many hours did it take you to print this bar mold ?

Nice to see some natural fibres being used. How does it compare stiffness wise? Most natural fibres seem very poor compared to more advanced composite fibres - albeit usually the environmental...

looks really good,we have been trialling some of the bcomp material at work and finding its not as good as it says on the tin,but i think for non structural applications like bodywork it should be...
