2. Choosing the best resin for dice

There are different types of resins available in the market.

When making resin dice, the thing to consider is the durability of the type of resin for the dice.

That’s because some may crack from drops while others might not hold up well in direct sunlight.

For example, an epoxy resin will last longer than polyurethane as it’ll resist cracking and yellowing.

The reverse is true with polyurethane which also has superior clarity. However, it doesn’t have much resistance against sunlight exposure.

3. Prepare the resin to pour into the silicone dice molds

When you’re making custom polyhedral resin dice, you can be creative with the desired appearance. This starts when you’re preparing the resin.

To mix the resin, mix the resin and hardener together at a 1:1 ratio. Do follow the ratio and instructions that are recommended on your resin kit.

Add a color agent while mixing if you want to color your DIY resin dice.

Most are easy to use, such as directly mixing in liquid resin pigments or colored mica powders.

You can mix multi-colored beads or colored glitter into the resin. This can be spread throughout the mixture to make a unique look for your resin dice.

Also, you can add small items into each resin die. You’ll insert them in the next step after pouring the resin.

Keep in mind that inserted objects will only be visible if your die is at least partially transparent.

Depending on the coloring agent you used, it’s possible to make a mix of transparent and opaque resin dice with color.

If you decide not to add coloring to your resin dice and only adding inserted objects, the resin dice will be transparent and your inserted items will be visible.

You can use the items above, or any dice-sized personal objects you have around the house to make your dice truly personalized.

4. Pour the resin into your silicone dice mold

Pour the mixed resin into your dice mold.

Make sure to fill the crevices thoroughly, as this could cause air bubbles.

Before letting it cure, you can use a heat gun to help get rid of any bubbles in the resin die casting.

Now is an important time to make sure everything is well settled in the dice mold.

If you have any items you want to insert directly into the dice, carefully do so with the help of toothpicks.

Resins tend to have strong odorous fumes, so make sure you are working in an area with good air ventilation. Open the windows or turn on the ventilation.

5. Let the resin dice cure

Let the resin dice cure for 48-72 hours or refer to the recommended time on your resin kit.

Do not rush the curing process. It is always better to go with the longer time when given a range.

With patience and care you can create beautiful custom dice in just a couple of days.

6. Demold and clean the dice

After allowing ample time for your dice to cure, you are ready to remove them from the silicone mold.

They should come out easily from the silicone molds.

If they are still sticky when you begin to remove them from the mold, they are likely not done curing. Removing them too early can ruin the cast, so patience is important.

Once you have successfully removed the cured dice from the silicone dice molds, you may need to clean them up.

Sometimes there will be extra resin along some edges of your dice. Carefully remove them with a Xacto knife.

Take extra care when doing this because a die that is not perfectly balanced will not roll properly.

After you’ve removed any extra material from the dice, you can use fine-grit sandpaper, followed by a finer grit sandpaper to make your resin dice smooth.

Congratulations! Your resin dice are completed and ready to roll!
