Will a vacuum cure epoxy?
Many have mentioned using the vacuum chamber for your mixture of resin+hardener. Even if you are using vacuum to infuse resin into your reinforcement , you still need to degas your resin after mixing in the hardener. For my epoxy resin, 10 minutes under vacuum pressure of -80 kPa works the best.

29” Hg of vacuum is sufficient for most applications. 2 mm of vacuum has been found sufficient for high volume production. Always use a large enough container to allow the material to rise under vacuum.
Vacuum Degassing
The container holding the resin should have enough headspace to accommodate three times the original volume of the resin. Vacuum is pulled to 29 inches of mercury. The air is sucked out of the resin which causes the bubbles to rise up and then collapse. This process typically takes a couple of minutes.
You CAN get rid of bubbles after your resin has dried.
Simply sand down the entire surface of your piece with coarse sandpaper, making sure you sand out the bubbles completely. Wipe away the sanding dust with damp paper towel, repeating as often as needed until the surface is clear of sanding residue.

You will need to use a pressure pot to create air-trap-free and bubble-free resin castings, something that is imperative to create clear resin casting. If you have air trapped in resin, and particular clear resin, it can create a cloudy color and you won't be able to achieve crystal clear castings.
