Variations of Resin Dice Molds

For regular resin dice, there are as many as seven different types of molds for the dice casting. The dice molds enable the formation of a polyhedral shape, in other words, a three-dimensional geometric with flat sides, pronounced corners and, linear edges.

In the game Dungeons and Dragons, the seven dice varieties make up a toolset. D4 up to D12 are used for assessing weapons, casting spells, attacking and, healing. D20 has the role of ensuring your chosen actions are complete.


D4: Tetrahedron Dice

Tetrahedron dice are four-sided, creating a pyramidal structure. Digits 1 through 4 appear on the surfaces, so each side has three digits. The numerals are placed at the apex of each pyramid side so that the same digit appears on each side. In playing these dice, the digit atop all sides is the number rolled. This die, due to its shape is more effectively tossed in the air than rolled on a surface.


D6: Cube Dice

The cube die is the most commonplace and frequently used in familiar games. This die features the numbers 1 through 6, one on each face. Opposite sides of the die make up the number 7. Cube dice in Dungeons and Dragons allot qualities to various personas.


D8: Octahedron Dice

This is an octagonal die with each side appearing as a triad. This die appears as though a pair of pyramids have been joined at their foundation. Each side has a digit between 1 and 8 and opposite sides add up to 9. Pertaining to Dungeons and Dragons this die evaluates harm caused by weaponry.


D10: Pentagonal Trapezohedron Dice

This particular die usually works with the percentile or D00 die. The 10 faced kite shape has the two endpoints where the peak and tip corners merge. This die has numbers 0 to 9 and the sum of the opposite sides adds up to 9. You would toss this die along with the percentile to obtain a numeric ‘percentage’.


D00: Percentile Dice

The percentile die is part of a pair of 10 faced dice that combine. This die will give you a percentage value out of 100. Each side of the die has a number from 00 up to 90 escalating in increments of ten. This die would be in a different color to the other 10 faced piece. To obtain a percentile, you toss both dice and combine the two results. If the dice rolled are both zero, then the worth equals 100.


D12: Dodecahedron Dice

This die has 12 pentagonal sides with the opposite sides adding up to 13. In Dungeons and Dragons, this die too is useful in determining damages.


D20: Icosahedron Dice

In the game Dungeons and Dragons, this die is the most common and well known. Featuring 20 sides, it is far bigger than the other dice. Each side creates an equiangular trigonal, with digits from 1 to 20 or 0 to 9, doubled. Opposing sides add up to 21.

Due to its shape, this die can be rolled the furthest. When playing Dungeons and Dragons this die confirms any action’s success or failure, these activities cover battles or ambushes and inspecting expertise and capabilities. Each merit on the die possesses a 5% possibility of success. The D20 is cast to strike, for example, you would then cast a second die to see the results of this attack. The second choice of die would take into consideration your weapon size.


D100: Zocchihedron Dice

This die is used as a novelty die as it does not typically form part of a seven-piece set. The 100 faced die was created by Lou Zocchi in the 1980’s and is roughly golf ball sized. This die is perfect for percentile rolling when used in role-play gaming.

How to Make Resin Dice with a Premade Mold

The art of how to make resin dice can vary, this depends on if you make use of a premade silicone mold or make your own. The following guide will explain how to make your own dice using a premade mold.



When learning how to make your own resin dice, some preparation is first required. You will need a clean, neat space in which to work, as resin projects may become quite messy. Your molds should be clean and properly dried and your tools and materials need to be close at hand as there will be limited time before the resin starts to dry.


Mixing and Pouring the Resin

Your first step in making your resin dice is to carefully measure and mix the resin. You will need to carefully follow the manufacturer’s directions, with regard to measurements and mixing time as the resin needs to be exact, in order for it to set.

  • Read the mixing ratio of resin to hardener and put each into a separate container.
  • Pour the resin along with the hardener evenly into a third container.
  • Using a skewer or stick mix the liquids well for 3-5 minutes or as recommended by the manufacturer. Be certain to scrape the bottom and edges of the container.
  • Should you wish to add a color, pour in a little bit of mica powder or alcohol ink at this point. Be careful as to how much you add, as this can affect the ratio of the solution.
  • Using a toothpick, modify the size of the hole in the mold. Pour the resin into the mold, the toothpick may help with the liquid going through the opening. Try to pour in the resin so as to avoid air becoming trapped in any crevices or indentations in the mold, as this may create bubbles.


Adding Decorations and Embedding Items

At this stage, you can decide to have either a clear dice, or incorporate color and decorations. Some people make dice to fit with the themes and characters in certain role-playing games. The following steps should be done before the resin is poured into the mold so that they mix effectively.

  • Colored mica powder or alcohol dye can be used to create rich, bright colors for your dice. The mica powders can achieve effects in metallic, glitter, pearlescent and many others.
  • You only need a small quantity, as these pigments are highly concentrated. Too much mica powder can leave your resin appearing cloudy and filmy.
  • You can get really creative with clear dice, like adding glitter, funfetti, dried flowers and so on to the colorless resin. You could embed little figures or trinkets to create a specific theme.



Before touching the mold, you will need to allow your resin dice to cure for at least 24 hours. If you tap the resin to check the process it should feel dry, silky and hard. If the resin is still tacky it will require more curing time. Different resin can set at different paces, anywhere from 24 to 72 hours as a result of the type of resin and the outside temperature. The resin may not set properly if the incorrect measurements have been used.

Should your resin remain unset, put it into the freezer to harden. You can then unmould the resin and throw it out as it can no longer cure any further.  If the resin is only slightly tacky, there is still a way to salvage your dice! Put the mold in the freezer for a night, then unmold the dice and put them in the oven at a very low temperature. This should reactivate the setting action.



When your resin dice cast has set and dried you are ready to demold or take the dice out of the silicone molds.

  • Be gentle in removing the molds, so as not to tear them, as they then have to be thrown away.
  • You may find that there is a superfluous substance around the edges. This is called sprue and makes up for shrinking that can happen during curing.
  • If you didn’t use a polished mold, your demolded dice may look opaque and misty. This will change in the final step.


Finishing Touches

You have just about completed learning how to make your own dice. Now for the final touches.

  • Firstly, the sprue needs to be removed as it makes rolling the die quite difficult. Use a small knife for this process.
  • As the sprue is removed, it leaves a rough edge; this can be smoothed by using fine sandpaper.
  • To polish your die’s surface, use sandpaper with 150 grit. Try not to sand away too much resin.
  • Following this, change to 180 grit sandpaper and then 220 grit. Increase the refinement of the paper until you are happy with the sleekness of the resin surface.
  • You may have to go as high as a 3000 grit sandpaper for your finished product. The die will be even and smooth, though it may still look a little misty.
  • Use water each time you sand to eliminate as much potential dust as possible.
  • Next, using a soft microfiber dishcloth and resin polish, polish your die to create a shiny, sleek surface.
  • You can use acrylic paint for fine work, including numbers or patterns on your dice.

When working with silicone, ensure that your workspace is neat and orderly. Decide if you are going to create a one or two- part mold, this will determine the pouring of your resin. The following paragraphs focus mainly on a one-part mold. Such molds have only a small opening, through which the resin is poured. Be sure to have an authentic die which you will use to make the mold.


Molding Material

A resin dice mold is best made from silicone as it doesn’t stick to materials like the resin, so easily releases the molded piece. The many advantages of silicone include:

  • The molds are reusable
  • It is non-toxic and safe for use
  • It is strong and durable
  • The molds are soft and malleable
  • It is an effectual release agent, therefore easily demolds


Mixing and Pouring the Silicone

Before mixing your silicone, your original die needs to be prepared. Heat the tip of a pin and push it into a corner of the die, then stick a piece of plasticine to the base of a container. Stick the top of the pinned corner of your master die into the putty, ensuring that it stays balanced and upright. Be careful not to use too large a vessel, otherwise you waste a lot of silicone.

  • When mixing your silicone, be sure to follow the instructions on the product, as ratios and setting times may differ. Mix both parts in a mixing cup.
  • Pour your silicone mix into the vessel with your master die, carefully covering the die without loosening it from the clay, pour until the silicone is about 5 mm above the die.
  • You then need to release any air bubbles by tapping the vessel gently.
  • Allow for the instructed curing time, usually about 24 hours to set properly.

For your first try, it may be easier to start by making an open-faced mold. For this method, use some putty to cover one side of the die, so that the plasticine is strong enough to stay up by itself, half an inch in height should suffice. You then put this into your container, pour the silicone and allow it to set.
