The standard dice molds consist of a set of 7 variations, these include:

  • D4: 4 sided dice in the shape of a triangle, which has only numbers 1 to 4 on the faces. There are 3 numbers on each face or surface. The numbers are arranged at each apex, and the number found on each apex is the same on all faces. When the dice are thrown, the number that is on the upright apex is the value you play with. This type of dice is not very easy to roll, instead it is thrown up in the air.
  • D6: 6 sided dice in the shape of a cube, this is the dice we are all familiar with. The dice has numbers 1 to 6, the total sum of the numbers on opposite sides adds up to 7.

  • D10: 10 sided dice, the shape of a kite. The two sharp corners of the dice are where the top and bottom points of the kite meet. This dice is usually numbered from 0 to 9, which will give you a total sum of 9 on opposite faces. But if numbered from 1 to 10, The total when adding the numbers on opposite sides is 11. Usually, all the odd numbers on the faces meet on one side by a point and even numbers meet on the opposite point surfaces.
  • D00: 10 sided dice, referred to as a Percentile Dice, as the result is calculated as a percentage of 100. This type of dice is usually used in pairs where one die is numbered from 0 to 9 and the other from 0 to 100 in divisions of 10. To differentiate between them, they are supplied in two different colors and are used mainly for roleplaying games.
  • D12: 12 sided dice, each face is in the shape of a pentagon. The total when adding the numbers on opposite sides is 13.

Mixing the Resin

How to make polyhedral resin dice? All the standard resin molds available are listed above and are all polyhedral dice, which means a dice that has multiple flat surfaces, all equal in size. There is a choice of resins available on the market. You will have to try them out to find out which one works best for you. For example, you can try EasyCast Resin or Art Resin.

Follow the instructions on the package, this ensures you only mix the quantity you need for your project. Pour your two-part resin into the disposable cups and mix using the spoon or other mixing tool.

The disposable mixing cups do not need to be expensive; you can make use of a medicine cup or use a paper cup. If you intend to make more than one dice at the same time, you will need to have the same amount of mixing cups available. The mixing spoon or utensil can be anything you have in your kitchen, as it can easily be cleaned after you have finished using it.

Mix the resin thoroughly and position your mold in such a way that when you pour it, the air does not get trapped in any of the depressions. Make use of a toothpick to help direct the resin into the hole. Once you have poured the resin into your mold, set it aside and allow to cure. Remember, the resin may have a strong odor, so make use of a respirator and work in a well-ventilated area.


Adding Glitter or embedded Items

Before you pour your resin, you must decide if you want to leave your dice clear or do you want to add something extra? You could add alcohol inks or mica powders to give your dice color. If you fancy glittery things, you could add some glitter to the resin. Remember, to always mix thoroughly before pouring. You could even embed a small figure or item to make the dice more personal.

Examples of objects to embed:

  • Small bracelet charms
  • Paper
  • Beads
  • Plastic items


Let it cure

Allow the resin to cure, which should take about 24 hours before you can handle the mold. A good test to see if your resin has cured properly is to check if it is hard and smooth to the touch. Depending on your resin, it could take 48 hours up to 72 hours for slow curing resin. If it is wet and sticky, your resin has not cured properly. This could be due to incorrect mixing of your resin or something that you added caused the resin not to cure correctly.


Demold your Dice

Once the resin has cured fully, you are ready to start demolding your dice casting. Remember, if it has not cured properly, it will still be sticky. If this is the case, you can put the dice casting into your freezer overnight and if the stickiness is gone by morning, your project is a success.

However, if it remains sticky, you have no other choice but to throw it away and make a new one. Be careful when you de-mold your dice so that you do not tear the silicone mold. You will not be able to use it again if you do.

Polishing and Finishing Touches

After you have successfully removed the dice casting from the mold, you may see a small amount of extra material still left along the edges of the dice. This extra material is called sprue and if you find this, it is a good sign. This means the polyhedral dice resin shrinks slightly while curing and your end product has perfectly formed.

If you fail to remove the sprue, you will soon discover that the dice cannot roll properly. Remove the sprue by making use of a utility knife or other sharp instrument. Your dice will still look slightly rough in that area, but you can use fine-grit sandpaper to sand it down until it is smooth.

We suggest using a P150-grit to start with. Sand your dice but be careful not to remove too much of the resin in the process. You need to continue with sanding, next using a P180-grit and then move on to a P220-grit. Continue with a P240-grit and so on until you are satisfied your dice is thoroughly clean and smooth.

To accomplish this type of finish, you will need to go all the way up to P3000 grit sandpaper, which will bring you to the final finish. To keep the dust to a minimum, you can use water between each sanding.

At this stage, although your dice is nice and smooth, it might still have a cloudy look. This is where you polish your dice, using a microfiber cloth and resin polish. You will then have a perfectly shiny finished product, which is ready to use. When using a polish, such as Headlight Cleaning Polish, make sure to follow the instruction printed on the bottle.   



How to make your own Dice Molds?

Prepare the area where you want to work and make sure there is nothing that will hinder your process. Next, you need to decide if you are going to make a 1-part or a 2-part mold for pouring purposes. For this article, we will be concentrating on a 1-part mold. If you want to dive deeper into mold making, also check out our mold making tutorial.

Instead of having one side open, the whole mold is sealed off. You will have an opening where you will pour the resin in when making your resin dice. You will have to have an original or a master dice, which can be an old dice you do not mind pouring silicone over.


Materials needed

  • Master or original dice
  • Silicone resin material
  • Cups or containers to place the original into
  • Cups or containers to mix your silicone in
  • Mixing spoon or tool
  • Plasticine or clay
  • Gloves to protect your hands
  • Goggles to protect your eyes when pouring, as well as when sanding.



Molding Material

You can use silicone rubber for your mold. Some advantages of silicone rubber include:

  • Silicone rubber is strong
  • It is soft and flexible
  • Serves as a releasing agent, allowing you to release your product easily.
  • The silicone is non-toxic and harmless, it is used for baking molds and baby pacifiers.
  • You can re-use it.

Mixing and pouring the Silicone

Take your master or original dice and heat the tip of an ordinary pin with the flame from a candle, then push the heated pin into one of the sharp corners of your master dice. Next, take your cup or container and put a small piece of plasticine or clay at the bottom of the cup. Place the tip of your master dice onto the clay. Ensure that the container you use is not too big, otherwise, you will waste silicone.

Next, mix the correct amount of silicone you need in your mixing cups. Make sure to follow the instructions on the packaging, as not all types of silicone have the same curing ratio and times. Pour the silicone into the cup over the positioned master dice, ensuring that it completely covers it.

Continue to pour until your silicone is about 5 mm above the dice in the cup. To complete this process, you need to remove any air bubbles that have been formed by lightly tapping the cup, which releases the air bubbles. Allow the silicone to dry, which should take about 24 hours. Remove your mold from the cup, you are now ready to go and make the resin dice of your choice.
