How to Make Resin Dice: A Complete DIY Guide for Tabletop Gaming

Creating your own resin dice is a rewarding craft that combines artistry with the thrill of tabletop gaming. Whether you are a Dungeon Master looking for custom sets or a hobbyist who loves unique accessories, making resin dice at home allows you to design dice that reflect your personal style. From glitter-infused numbers to translucent colors, the possibilities are endless.

This guide will walk you through the entire process of making resin dice, from selecting the right materials to demolding and finishing. You will learn about the essential tools, safety precautions, and techniques to produce professional-looking dice that are balanced and durable. Let's roll into the world of DIY resin dice.

What You Need to Make Resin Dice

Before you start, gather all the necessary supplies. The foundation of any resin dice project is a high-quality resin. For dice, a clear epoxy resin like the CRAFT RESIN Arts & Crafts resin 34 Oz is an excellent choice because it cures crystal clear and has a 1:1 mixing ratio that is easy to work with. You will also need silicone dice molds, which come in various shapes and sizes. A set of 3D Skull Resin Molds can add a gothic flair, but for standard dice, look for molds with sharp edges and precise numbering.

Other essentials include mixing cups, stirring sticks, a digital scale for accurate measurements, and safety gear such as gloves and a respirator. For coloring, you can use mica powders, alcohol inks, or even glitter. A heat gun or torch is helpful for removing bubbles, and a pressure pot is recommended for achieving bubble-free dice with perfect clarity. Finally, sandpaper in various grits and a polishing compound will help you finish the dice to a glossy shine.

• Always work in a well-ventilated area to avoid inhaling fumes.
• Use silicone molds specifically designed for dice to ensure sharp edges and proper numbering.

Step 1: Prepare Your Resin and Molds

Begin by setting up your workspace. Cover your table with a silicone mat or wax paper to catch drips. Place your dice molds on a level surface. If you are using a new silicone mold, wash it with mild soap and water to remove any dust. Dry it thoroughly. For the resin, carefully measure equal parts of resin and hardener by weight using a digital scale. Pour the resin into a mixing cup, then add the hardener. Stir slowly and thoroughly for at least two minutes, scraping the sides and bottom of the cup to ensure a complete mix.

If you want colored dice, now is the time to add your colorants. A small amount of mica powder or a drop of alcohol ink goes a long way. Stir gently to avoid introducing bubbles. For a marbled effect, swirl the color partially. Let the mixed resin sit for a few minutes to allow any bubbles to rise to the surface. You can then pop them with a heat gun or torch, passing the flame quickly over the surface.

• Use a slow, steady stir to minimize air entrapment.
• Test your color mix in a small amount of resin first to see the final shade.

Step 2: Pouring and Curing the Dice

Carefully pour the mixed resin into the dice molds. Fill each cavity slowly to avoid overflow. For dice with numbers, pour until the resin reaches the top of the mold. If you are using a mold with a separate lid, you may need to add a little extra resin to account for shrinkage. After pouring, use a toothpick or a thin stick to gently move the resin around the edges of the numbers to ensure they fill completely. This step is crucial for legible dice.

Once all cavities are filled, place the mold in a pressure pot set to 30-40 PSI for 12-24 hours. A pressure pot is not mandatory but highly recommended for eliminating bubbles that can ruin the dice. If you do not have one, you can let the resin cure at room temperature for 24-48 hours, but you may have more bubbles. After the initial cure, remove the dice from the molds. They will be slightly soft but should hold their shape. Let them cure for another 24-48 hours on a flat surface to fully harden.

• A pressure pot is the best way to ensure bubble-free dice.
• Do not rush the curing process; full hardness is essential for sanding.

Step 3: Sanding and Polishing Your Dice

After full cure, your dice may have a rough edge or a small sprue mark from the mold. Start sanding with a low-grit sandpaper, such as 400 grit, to remove any imperfections. Work your way up through 600, 800, 1000, and finally 2000 or 3000 grit for a smooth finish. Sand each face evenly to maintain the dice's balance. Use a sanding block or wrap sandpaper around a flat object to keep surfaces flat.

Once sanded, polish the dice to a high gloss. You can use a plastic polish compound and a soft cloth, or a rotary tool with a polishing pad. Apply the polish in circular motions until the dice shine. For an extra glossy finish, you can apply a thin layer of UV resin and cure it with a UV light. This step is optional but can give your dice a glass-like appearance. After polishing, clean the dice with a damp cloth to remove any residue.

• Sand in a well-lit area to see scratches clearly.
• Always sand in one direction to avoid swirl marks.

Tips for Perfect Resin Dice Every Time

Making resin dice takes practice, but a few tips can help you achieve professional results. First, always use a digital scale for measuring resin and hardener. Eyeballing the ratio can lead to sticky or brittle dice. Second, invest in high-quality silicone molds that are flexible and non-stick. This makes demolding easier and preserves the sharpness of the numbers. Third, consider using a pressure pot for bubble-free dice. It is a worthwhile investment if you plan to make multiple sets.

For unique effects, try layering different colored resins or embedding small objects like glitter, dried flowers, or tiny charms. However, ensure that any embedded items are fully encapsulated to avoid air pockets. You can also use a UV resin like the CRAFT RESIN 30g Bonding UV with Flashlight for small repairs or to add a glossy top coat. Finally, label your dice with the resin type and cure time for future reference. Happy crafting!

• Store leftover resin in a cool, dark place to extend its shelf life.
• Experiment with different color combinations to create custom sets for your gaming group.
