Imagine this: you have a great design idea for a product, accessory, or a decor item in mind and you want to see it come to life! You set up your 3D printer and are ready, but there’s one small problem. You don’t know which 3D printer resin is right for you. This might not seem like too big of an issue at first, but it is!

Believe it or not, but choosing the wrong 3D printer resin can lead to wrapped edge and brittle pieces. What does that mean? Well, you get a 3D design that falls short of your expectations and no one wants that to happen. So, in this article, we’ll look at what a 3D printer resin is and how you can choose the right one by understanding resin properties.

Let’s begin!

Understanding 3D Printer Resin

3D printer resin is basically a liquid material that’s composed of photopolymers. The material, upon reaction with light, changes into a solid. Different types of 3D printer resins, like flexible and water washable resin, are designed to be used in stereolithography (SLA), digital light processing (DLP), and LCD-based 3D printers.

Choosing A 3D Printer Resin Using Its Properties

As far as choosing the right 3D printer resin is concerned, you need to understand the different properties of the resin. Doing so is essential as it can help you make an informed decision that leads to the desirable results. The key properties of 3D printer resin include:

Thermal Properties

These are properties that come into play when your print or its final application is subject to heat. To consider thermal properties when choosing a resin you must comprehend what Heat-Deflection Temperature (HDT) and Glass Transition Temperature (Tg) are.

HDT is the temperature at which your chosen material begins to melt. So, if you plan on using the 3D print in a high heat environment, then choose a resin that has a higher HDT than its counterparts.

Tg is the temperature at which the resin changes from glass solid to a more rubber-like flexible state. So, if your prints need to maintain rigidity, you need to choose 3d printer resin with high Tg levels.

Mechanical Properties

These are properties that determine how durable, flexible, and strong your 3D prints are. All three of these factors are what determine how the resin will behave when it’s put under stress. A few critical things worth considering here include:

Flexural Strength – this property basically tells you the extent to which a 3D printer material can bend before it deforms. Therefore, if you want an output to be rigid, then you need to choose a material with high flexural strength.
Elongation at Break – to keep it simple this property tells you how much material can bend before it breaks. If printing something that needs to be flexible, you need to choose a resin with a high elongation at break.
Impact Resistant – this metric tells you the extent or severity of impact your 3D printer resin will be able to sustain. If your output is likely to be used in environments where the probability of impact is high, then choose a resin with high impact resistance.
Tensile Strength – this refers to the material’s ability of withstanding being pulled apart. Therefore, if you’re creating parts like that need to be durable and strong, then you should choose a 3D printer resin with high tensile strength.

Optical Properties

These properties, as the name suggests, are ones you should consider when it comes to the appearance of your 3D printed output, be it for functional or aesthetic purposes. Two of the most common aspects to consider here include color and transparency.

You have a variety of different options ranging from solid to subtle shades to choose from. When choosing a color, it’s important to consider how it will affect the functionality, not just the aesthetics. For example, lighter shades can help bring out intricate details, whereas darker ones can help mask internal structures.

For transparency, the 3D printer resin options that are available are designed to cure without clouding. This basically allows light to pass through your printed design while keeping distortion at a bare minimum. However, such resins may require more care as they can develop a yellowish shade or become clouded overtime.

Additional Resin Properties

When you’re choosing 3D printer resin, there are a few additional properties other than the ones mentioned above you need to consider. These include:

Biocompatibility – first and foremost, you need to determine if your 3D-printed parts will come into contact with skin during use. If they are, then you need to go for biocompatible resins. These are specifically designed to be used for purposes like surgical guides, dental models, wearables, and more.
Viscosity – this refers to how thick or thin the resin is. If you choose a thinner 3D printer resin, then you must know that while they are great for developing smooth and clearer surfaces, however, they’re also trickers to work with and require extra care.
Cure Time – before you begin 3D printing, know that cure time refers to the duration it takes for the resin to harden when exposed to light. While faster curating resins can speed up your printing process, if a resin cures too fast it can lead to brittleness in the output.

Apart from deciding which 3D printer resin based on their properties, you also need to consider their cost and availability. Both these factors can vary based on the properties and the amount of resin you choose to buy.

In addition, it’s better to stick with a reliable supplier. By doing this, you can ensure that the resin variants you buy are of the same quality as it can help maintain consistent performance from one batch to another.

Key Takeaways

Choosing the wrong 3D printer resin can negatively influence the quality of your output. When it comes to 3D printing, you need to consider various resin properties. Common examples of such include thermal, optical, mechanical, and more. By understanding and analyzing the 3D printer resin properties, you can make informed decisions and choose a resin that’s right for your specific needs!
