When it comes to 3D printing filament, there are a few different types of resin on the market. In this post, we will be discussing the different types of SLA resins available and their applications. SLA resins are created using a process called stereolithography.

This type of 3D printing uses light to cure layers of liquid resin into solid objects. The light source is usually a laser, and the object is built up layer by layer until it is complete. There are a few different types of SLA resins available on the market, each with its own unique properties. Read on to learn more about the different types of SLA resins and their applications.

What Is SLA Resin?

SLA resin is a type of photopolymer that is used in stereolithography (SLA) 3D printing. SLA resins come in a variety of formulations, each designed for specific applications and material properties. The most common type of SLA resin is acrylate-based, which is available in both clear and opaque formulations. Other types of SLA resins include epoxy-based, silicone-based, and urethane-based resins.

Each type of SLA resin has its own unique set of material properties that make it better suited for certain applications. For example, acrylate-based resins are typically more chemically resistant and have higher heat resistance than other types of SLA resins. Epoxy-based resins, on the other hand, are often used for applications requiring high strength and stiffness.

When choosing an SLA resin for your 3D printing project, it is important to consider the specific properties that you need. Different types of SLA resins can be mixed together to create custom blends with specific material properties. This allows you to tailor the material to your exact application needs.

How To Choose The Right SLA Resin For Your Project:

When it comes to choosing the right SLA resin for your project, there are a few things you need to take into account. The first is what type of resin you need. There are two main types of SLA resins: photo-sensitive and thermal. Photo-sensitive resins are activated by light, while thermal resins are activated by heat. Each has its own advantages and disadvantages, so you’ll need to decide which is best for your project.

The second thing to consider is the curing time. Curing time is the amount of time it takes for the resin to harden after it’s been exposed to light or heat. Some resins cure very quickly, while others take much longer. Again, this is something you’ll need to take into account when choosing a resin for your project.

Finally, you’ll need to think about the cost of the resin. Resin can be quite expensive, so you’ll need to make sure that you choose a resin that fits within your budget. With all of these factors in mind, you should be able to find the perfect SLA resin for your next project!

Different Types of SLA Resin:

There are several different types of SLA resin that can be used for 3D printing. Each type of resin has its own unique set of properties that make it more or less suited for different applications.

The most common type of SLA resin is photopolymer resin. This type of resin is sensitive to light, which is used to cure it during the 3D printing process. Photopolymer resins are available in a wide range of colors and can be used to create parts with high accuracy and detail.

Another popular type of SLA resin is epoxy-based resin. Epoxy-based resins are not as sensitive to light as photopolymer resins, but they are more durable and have better heat resistance. Epoxy-based resins are often used for industrial applications where parts need to withstand high temperatures or harsh environments.

acrylic-based resins are another option for SLA 3D printing. Acrylic-based resins are similar to photopolymer resins in terms of color options and print quality, but they are more brittle and have less impact resistance. Acrylic-based resins are often used for prototyping and low-volume production runs.

Pros And Cons Of SLA Resin:

SLA resins offer several advantages over other 3D printing materials. They are strong and durable, making them ideal for parts that need to withstand high temperatures or constant wear and tear. SLA resins also have a very low shrinkage rate, meaning that your printed parts will be very accurate.

On the downside, SLA resins can be more expensive than other materials, and they require special equipment to print with (such as an SLA printer). In addition, because SLA resins are so strong, it can be difficult to remove supports after printing.


There are a few different types of SLA resins that can be used for 3D printing, but the most popular ones are PLA and ABS. Each type of resin has its own benefits and drawbacks, so it’s important to choose the right one for your project. If you’re not sure which type of resin to use, ask a professional or do some research online to make sure you’re using the best possible material for your needs.
