How do I make a resin mold?

Making your own molds for resin is easy. You can use items found around the house, or even make them from scratch using wood or metal.

You can also use silicone or rubber to make molds for resin, which are reusable and will last a long time with proper care.

Can you make your own mold for resin?

Yes! You can make your own mold for resin. A mold is a reusable object that is used to make copies of an original object.

Molds are made of materials that won’t be damaged by the resin and will hold their shape during use. There are many different types of molds, including:

  • Silicone rubber – great for making small items like jewelry or figurines
  • Polymer clay – great for making larger objects such as bowls or vases
  • Paper – good for creating masks or sculptures

What can you use to make a mold for resin?

  • Make sure you have a mold release. This will allow the resin to be easily removed from the original object.
  • Use wax paper and/or duct tape to create a smooth surface for your resin to adhere to when it hardens. For example, if you want to make a mold of an apple, you would put your wax paper or duct tape on top of a piece of wood and then put the apple on top of that layer (so it’s sandwiched between two layers).

Make sure it’s even-sized all around so that when you pour in liquid plastic, nothing sticks out too far or is too short compared with anything else (because this can cause air bubbles).

If there are any areas where there are scratches or imperfections in your model (like dirt), those areas will show up again in another form—but only if they’re deep enough!

What material is best for resin molds?

Resin molds are made from a variety of materials, including:

  • Plastic (such as polyethylene)
  • Rubber
  • Silicone rubber
  • Wood and composite wood products, like MDF and particleboard
  • Ceramic materials, such as clay and porcelain
  • Metal (aluminum is particularly good for making molds because it’s easy to cut into different shapes)

You can also use clays like plaster or paper mache to make your own molds. When you’re done with the mold, you can pull it off of its original object (like a piece of jewelry), then pour resin into it to create copies!

What will resin not stick to?

How can I use resin without mold?

You can use resin without a mold if you’re crafty and creative. A skilled crafter may be able to make a usable piece of art with only resin, but it won’t look as good as it would with the right mold.

Before attempting to create a piece of art or jewelry using resin without a mold, consider your experience level in crafting and the quality of the finished product that you want.

If you have never used resin before or don’t know how to work with glass and other materials involved in making jewelry, then it is probably best for you to start with something easier such as air drying clay or polymer clay instead.

How do I make my own molds?

You can’t just take two pieces of plastic and expect one to make a good mold, you need something called “casting material.”

There are many different types of casting material, but for this purpose, we will be using silicone. You can buy these at most hardware or craft stores in the mold-making section or online.

Silicone has two main components: the base which is white, and the catalyst which is clear (you won’t use any of this).

How do you make reusable molds for resin?

For each of these categories, there are several options. You can use silicone rubber molds, silicone molds, plaster molds, plastic molds (such as the kind that photographers use), rubber molds (the most common type), wax molds, and metal molds.

Wood and ceramics are also used for making resin molds. Last but not least you can make a mold out of paper.

Mold making materials vary in cost and durability:

Silicone: $$$$+ – High-quality silicone is more expensive than other types of mold making materials but will last longer with regular use.

Silicone is great for small parts because it’s flexible which means the finished piece will be flexible too! A good example would be jewelry pieces like rings or earrings made from resin casting kits.

Plaster/Paper Mache: $$$ – This material has been around forever so obviously it works well enough to still be used today!

It’s easy to work with but lacks flexibility so if you need something that’s going to bend then this might not be your best option unless your part has some give built into it already by being smaller than average size or having some sort of support structure added before casting time occurs.”

What can I use to make a mold?

There are many different materials you can use to make a mold, but some are better than others. Plaster is cheap, easy to work with, and effective for small items.

Silicone is a good choice if you need to make a lot of molds or need something that will last longer than plaster. Rubber works well if you want something flexible (like rubber) or something that’s hard and durable (like plastic).

Silicone and rubber molds tend to be expensive because they’re usually reusable many times over before they start losing their integrity; however, if you only plan on making one or two molds then it might not be worth the cost.


We’ve talked about how to make your own molds for resin, as well as what materials you can use. We hope this information has helped you figure out the best way to get started on your next project!
