Ever wanted to make your own DnD resin dice? I finally gave it a shot using a Let’s Resin silicone dice mold—and while I’m still a beginner, I learned a lot along the way! In this step-by-step guide, I’ll show you how to make resin dice at home, what mistakes to avoid, and tips to improve your custom dice.

I’ve wanted to make resin dice for a long time, and I finally gave it a try! I’ll be the first to admit that I’m no pro (yet), but that’s exactly why I wanted to share this. Sometimes it’s easier to learn from another beginner because I’m making the mistakes so you don’t have to. I’ll keep updating this post with new tips and tricks as I get better, but if you’ve been thinking about making your own dice, this is your sign to go for it. Don’t be scared to try – it’s way more doable than it looks, and quite fun!

Instructions to Make Resin DnD Dice

Measure and Mix the Resin

Before you do anything, be sure to put on a mask and gloves and work in a well ventilated area. I also have an air purifier running (this one).

Then measure equal parts of Part A and Part B and add them to a mixing cup (this is the type I used – use code DANAB10CFT for 10% off). I used 100ml of each, but this was wayyy too much for this mold so you could probably do 50ml of each.

Note: It’s super important that they are the exact same amount – otherwise the resin will not cure properly.

Tip: Use a popsicle stick to scrape out the resin from the measuring cups.

Tip #2: Make sure the mixing cup you’re adding them to is 2x the size of the total volume of resin you’re using. For example if you’re using 50ml of each part, this is a total of 100ml so you want the mixing cup to be at least 200ml large. The bubble remover causes the mixture to expand and you don’t want an overflowing mess.

Add any color you’d like. It’s recommended that for your first set of dice, keep it to one color.

I made mine purple by adding mica powder at first (from this set). Then I wanted more depth to the color so I added purple alcohol ink as well (from this set) – use code DANAB10CFT for 10% off on both the mica powder and alcohol ink!

Stir it together for several minutes (~5 min). Be sure to wipe the sides to ensure it’s fully mixed.

You can also use an electric mixture, which I actually purchased after making this set of dice (this is similar to the one I have).

It’s recommended to be careful while stirring to avoid making bubbles, but if you’re using a bubble remover like I did (highly recommend and likely why mine came out decent) it’s not as big of a deal.

Use a Resin Bubble Remover to Remove Bubbles

Using a bubble remover is key to getting a decent set of resin dice. Bubbles are really what prevent you from being successful so I highly recommend investing in a bubble remover (this is the one I have – use code ABCRAFTY10 for 10% off!).

To use it, place the cup of mixed resin inside and push the top down. Then you just need to set the timer (generally between 5-10 minutes) by turning the front nob. Then press the start button.

It will automatically turn on and you’ll see it will start to bubble and then collapse.

To get any remaining bubbles on the top, use a heat gun.

Tip: Be careful with this – I stupidly had mine in a solo cup so when I used the heat gun I melted the cup – oops!

Fill the Dice Mold

Carefully pour the resin part way into each cavity of the mold. You want to fill it about 1/3 of the way full.

You want to basically get the bottom coated.

This is the mold I’m using – you can get it for 10% off with code ABCRAFTY10

Then you can use a toothpick or in my case a tiny spoon from a previous resin kit to push the resin into the bottom corners and smear it up the sides into any corners along the sides.

The goal is to remove any bubbles in the corners and to begin coating the sides so there aren’t bubbles.

Use a heat gun to remove any surface bubbles (this is similar to the one I have).

Note: The brand, Let’s Resin, specifically told me not to use a heat gun on the mold as it can damage it, so do this step at your own risk. I personally will continue to do this as the mold isn’t expensive and I’d rather have a better set of dice.

Then you can fill the molds all the way. You want to leave a bit of a dome, which will press into the top of the mold.

Tip: Lift the dice mold to check for bubbles. Use the toothpick to pop those bubbles or bring them to the surface.

Place the lid on, rolling it on slowly from one side to the other.

For this set I actually put the lid on directly without rolling it and it created bubbles on the top so this is definitely a “learn from my mistake” moment!

Let it Cure and Demold

Place a weight on top of the lid to ensure there is a tight seal. I just used the box of alcohol inks.

Then you’ll want to let it set for 24-48 hours (mine took 2 days). You want to make sure it’s completely hard before you demold them.

Tip: To make sure the resin has cured, I leave the mixing cup I used next to the mold to also cure. Then I can check whether the resin in the mixing cup has finished curing.

Once it’s fully cured you can then remove the dice from the mold. They should pop out pretty easily!

Sand and Polish the D20

One thing that’s weird with this Let’s Resin dice mold is the 1 face on the D20 is raised. It’s apparently a known issue, but for now that’s still how the mold looks.

The way to fix this is to sand it down.

Starting with a 1500 grit sandpaper, spray it with water and rub that face in circles on a flat surface. This allows you to wet sand, which prevents you from breathing in any resin dust.

Then repeat the process with finer and finer sandpaper (I received them from Let’s Resin, but here’s a set that could work). Next use the 3000 and then 5000 grits.

Paint the Numbers

Use acrylic paint to paint on the numbers (this set has a bunch of colors). You don’t have to worry about getting it outside of the numbers, it will easily wipe off the face.

Let it dry and then wipe off the excess with a paper towel.

I had to do two coats to make the numbers pop.

Tip: I recommend using a contrasting color so that the dice are easy to read. In my opinion, there’s no point to having a set of dice that is difficult to read.

Now your dice are ready to use!

If you make your own set, I’d love to see it! Tag me on Instagram @ab.crafty or share it in the community section of my channel!
