Where do you mix resin?

Mixing resin is a very important part of the process, but it is also one of the most difficult parts to get right. This can cause problems for both you and your clients. Here are some of the things that could go wrong if you mix resin incorrectly:

  • You may end up with a weak cast or mold. When you make a mold or cast from liquid resin, it needs to be able to hold its shape without breaking once dried out. This means that if your mixture isn’t set up properly, chances are good that it won’t hold its form when dried out and hardened into an object.
  • The color might not come out right for you or for your client! If you’re making something like jewelry where color matters, then mixing up your own batch at home can create problems because there’s no way to get exactly what shade someone wants when they tell you what kind of jewelry they want to make unless they know how much paint goes into each bottle along with other factors like how thick it will be on their piece once finished

Where should I mix my resin?

When you mix resin, you should always be in a well-ventilated area. As you are mixing the product, it will release fumes that can cause headaches or nausea if breathed in.

The surface on which the product is mixed should be non-porous and flat so that no air bubbles form. It also needs to be cleaned easily because resin leaves behind a sticky residue that can become messy if not cleaned immediately after use.

The room where you mix your resin should ideally have good lighting so that you can clearly see what’s happening as it mixes up (or down) with water.

The temperature of the room should be kept at about 70°F so that it doesn’t freeze when mixing with water or become too warm when mixing with alcohols like denatured alcohol or ethanol alcohol; both are popular ways to thin out Epsom salt solutions before adding them into your molds!

What is the best way to mix resin?

While there are many ways to mix resin, the most common is with a stir stick. The best way to do this is by mixing thoroughly and ensuring you’re using the correct ratio of resin and hardener.

If you want to be extra careful with your steps, we recommend getting yourself a scale so that you can measure out each ingredient separately prior to mixing them together.

Once you’ve mixed your resin and hardener thoroughly, it’s time for another step: allowing them to sit for the appropriate amount of time before mixing again.

In general terms, most resins require about 24 hours after being mixed before they have fully cured. During this period of curing time, it’s important that no one touches or disturbs them (especially heat sources), as this will disrupt the chemical reaction process necessary for curing.

After 24 hours have passed without any disturbance from humans or pets in your home – especially warmth from cooking appliances – go ahead! Mix away!

What do you mix epoxy resin in?

The best way to mix resin is in a dedicated disposable mixing cup. These are available from your supplier, but you can also use plastic or glass containers that you have laying around.

Mixing sticks are made of metal and plastic and are available at most hardware stores and home improvement centers.

You might want to invest in some disposable gloves as well, so you don’t get the epoxy resin all over your hands while you mix it up!

How do you use resin mixture?

Before you can use the resin, you’ll need to mix it with a hardener. It’s important that you stir the two together for 2-3 minutes, making sure to scrape all the sides and bottom of your cup as you go.

If using a stick blender, set it for 60 seconds and keep mixing until all of your bubbles are gone. The mixture should be completely mixed within this time frame; if there are still large bubbles or streaks in your mixture after 60 seconds then continue stirring until they’ve all disappeared.

You’ll know when this happens because once mixed, resin will have a milky appearance instead of being clear like water or milk (though slightly thicker).

Can you mix different resins together?

You can mix different epoxy resins together and they will cure into a solid plastic. Epoxy comes in many different formulations, so you have to be careful when mixing different brands.

Some epoxies will not bond to polyester, while others will not bond with isopropyl alcohol. However, most epoxies can be mixed with each other without problems.

It also depends on the type of sanding that you want to do and what kind of results you are looking for in your finished product.

What should resin look like when mixed?

  • Be sure to mix your resin in a well-ventilated area.
  • The resin should be clear and not cloudy. It will look like water but have some viscosity to it (thickness). If there are any particles in the mixture, they should be small and round. They should not be stringy or clumped together into large lumps or chunks of material. If you can see anything other than those fine particles, then you need to use another batch of resin as this one is bad!
  • When mixing resins, do not make any sudden movements with your hand or stirring stick that could cause bubbles or air pockets within the substance itself; this will ruin your work as these can make paintbrush strokes unevenly applied when painting over them later on down the line (and trust me – nobody wants that!). Instead, try gently stirring around until no more bubbles appear before continuing on with mixing up another layer of pigments into each layer already applied before cleaning off excess pigment from the mixing stick onto a paper towel if needed then repeat the process until all layers have been covered sufficiently.”

What goes first resin or hardener?

The resin goes first. You will not be able to mix the hardener unless you have some resin in your container, so don’t worry about getting them mixed up at this point.

The instruction on the bottle will tell you when to add in your hardener, and usually, it’s just a matter of adding a little bit at a time until it looks like mayonnaise (a creamy texture).

Sometimes, however, depending on the type of project that you are making, you might need to use two different types of curing agents: one for “instant” cure and one for “bonder” cure. For example, if I am making something that needs to be cured overnight before I can use it (so basically anything bigger than 5-10lbs), then I need both epoxies together: one epoxy with no added hardener and one with an added catalyst that speeds up the process by several hours instead of days (or weeks!). This is called an “instant bonder”.


You’ve learned about the different types of resins and what types are best for each situation. You also learned how to mix resin and apply it to a surface. Now that you know all this, you can start creating your own 3D objects!

You should now be able to explain why resin is an important material for 3D printing, and how you can use it in your projects.
