Hey yo, I have been struggling for some time to make a working dice vault silicone mold for resin casting, and through many iterations, I have made something that works quite well for me. Hopefully these jigs will serve you good as well.
Some important specs:
- Hex die slot width, from corner to corner - 29mm
- Magnet slot diameter - 8.3mm, made for 8mm magnets
- Dice vault diameter - 98mm
- Mold bottom diameter - 170mm (aka your pressure pot diameter should be bigger than that)
Molding instruction:
You can substitute moldwall with cardboard and all of the vents and regmarks with whatever you can find lying around. Additionaly, you can use plywood to create your own moldbottom and moldlid.
If you missed or decided not to use registration marks, during this step cut the registration keys in the silicone.
The casting process is simple enough - Apply resin release on the moldbottoms, moldlids and silicone parts. Mix and pour resing into both "deep" silicone molds (do you magic - dirty pours, glitter, petri dish, you name it). Cover the other silicone parts (flat lids) with a thin layer of resin. Pop dem bubbles. Fix mold pieces between moldbottom and moldlids with rubberbands. Twist and turn the contruption a little to squeeze excess resin out and make sure everything is snug and in place. Top the resin off into the center vent hole, you should see that you have excess coming from the secondary vent holes. Place everything into the pressure chamber and wait for results!
Tips and tricks:
- Although different parts of the model require both fdm and sla, you can alternatively substitute mold lid and bottom with wooden parts.
- Watch mold making process video by Robert Tolone.
- Use spray mold release on the inside of the vault, or it can easily rip.
- When casting, coat the lid mold with resin to avoid bubbles.
- To cut the funnel from the model when cast, use a big knife to avoid chipping the vault (preferably right after the cure time has passed aka while it is a bit soft).
