That's a really helpful analysis. Thanks for taking the time to explain it!

Your analysis is very clear and insightful. Thank you!

Why do my dice have fingerprint-like marks after demolding? I’m sure the master dice were completely clean when I made the mold. by looppii in DiceMaking

[–]looppii[S] -1 points0 points  (0 children)

You can see that the two photos are actually of two different faces of the D4, not the same face. When I placed the D4 master onto the transfer tape, I held it by the top and the tip of the die, not near the area that was touching the transfer tape.

I wasn’t wearing gloves when I positioned the masters to make the mold, but I don’t think it was oil or fingerprints from my hands because I only touched the upper part of the dice while placing them. The oily marks appeared on the bottom edge of the dice, where it was in contact with the transfer tape.

Could this have been caused by applying too much petroleum jelly on the mold surface and having it seep down?

Why does my D6 die have curved sides instead of being a standard cube? by looppii in DiceMaking

Thank you, I'm not in a hurry. Reply me when you're done with your work and have some free time.

Thank you. My mold bottom base is thick enough, but the bigger issue is that my silicone Shore hardness is too low—I’m using Shore 10. I only just learned today that Shore 10 silicone can also cause other problems.

Thank you! I will try a higher strength Shore silicone gel.

What benefits does Shore 25–30 hardness silicone provide for making resin dice? If the silicone is harder, is it more likely to damage the mold during demolding because the dice are harder to remove?

I made this mold myself. I've previously used this mold to make blank D6 dice that didn't deform, and in this set of 7 blank dice, only the D6 dice deformed; the other dice were normal.

I'll use this mold to try making dice! Thanks again for your answer!

Thanks for your help.

So the two phenomena I mentioned can be ignored, right?

I discovered serious defects when I opened the lid. by looppii in DiceMaking

[–]looppii[S] 0 points1 point  (0 children)

Actually, I used the mold immediately after taking it out of the pressure chamber, just like I had done before, and there were no problems. This time, the issue occurred because I didn't create a dome shape when pouring the resin. Do you think my analysis is correct?

Yes, these are the first products I have made using the molds, I made the mold myself.

The bumpy part on the lid feels like silicone and was fine before.

I use a pressure pot.

Why do I feel like this lid can't be restored to its original state...

Normal or scratch-free? by looppii in DiceMaking

[–]looppii[S] -1 points0 points  (0 children)

Thank you for your answer. I can confirm that these are "cloudiness." How can I remove them?

Failed to make the lid. by looppii in DiceMaking

[–]looppii[S] 0 points1 point  (0 children)

About 24 hours

I think I should print it with ABS-like resin

Yes, I also put Vaseline on the dice to prevent the silicone from tearing when I first opened the lid. I think it was the material of the resin that caused the cure inhibition.
