Pressure Pot vs Vacuum Chamber | Resin Dice Casting

In this video, I go over the differences in Pressure Curing Resin for Dice Making, vs using a Vacuum chamber to remove the bubbles in your resin. In essence …


  1. Why could you not feather it when vacuum chamber is going. Such as when the resin starts getting volatile you open the valve on the lid and let it go back down then close valve and repeat. Little tedious but oh well.

    Is it too thick and need to be a thin layer perhaps?

  2. I feel like it's also worth noting that your example used a simple form that allows the bubbles to rise straight out of the top of the mold. In many cases the mold will have air trapped inside that won't simply rise to the pour hole. It will expand and stay inside the complex form unable to rise out. Thanks for the video! so cool.

  3. If anyone is looking for a set like these super clear dice, check out Gamescience! they make precision sharp edge dice that are clear or coloured, and you can get them uninked!

  4. are pressure casted die more prone to cracking when put under heat? Those microscopic bubbles dont go away, so arent there a ton of microscopic pockets of high pressure bubbles?

  5. I know this is an old vid but I hope you (or someone else who knows) see this anyway: do you know if it's possible to use one of those pressure pots for cooking instead of this one or aren't they good enough?

  6. Thank you for this info, I had no idea about this. So have you checked to see how pressure pots work with silicone? If i dont have to get a vacuum chamber for now that would be great.

  7. Not sure if this has been asked:
    I'm just starting out and looking into getting either the pressure pot or vacuum chamber, and noticed you purposely mixed to make bubbles before this. If you warm the resin to reduce the bubble while mixing, then use the vacuum chamber. Would that decrease the overflow?

  8. I'm not a dice goblin and even I know you don't vacuum pull a mold. Vacuum pulling the resin ahead of time, then pouring it into the mold is a lot more convenient in my opinion than leaving the dice in a pressure pot. The pressure pot needs to be turned on the entire time while the resin is curing, and depending on what method you're using to keeping the pressure pot pressurized, it can be pretty loud. A vacuum chamber needs to be active for a few minutes, until the resin doesn't look like it's foaming anymore, and then it's ready to pour and you can just leave it over night.

    It's basically just the same process as a pressure pot, but instead of pouring first and putting in a pot second, you put it in a vacuum chamber first and then pour it.

  9. Thank you so much for this video! I'm searching for casting videos because I'm willing to do silicone casting. In this case, which one would be better to make solid silicone objects: the vacuum chamber or the pressure pot? Do you know it?

  10. Thank you so much to clarify this difference between the two.
    Do you recommend a small Pressure pot and pump combo that I can buy to create small objects?
    Most pressure pots I saw, assumes you already have an air pump.

    Thank you again.
