Is resin a strong material?

Well, it's true that most standard resins are relatively fragile compared to other 3D printing materials and are not recommended for stressed parts or for outdoor use, although there are strong and durable resins on the market that are specifically formulated for stronger applications, and they can be very strong. Resin is lighter in itself, but its material may be heavier than its stated shape. In addition, it is still much lighter than its counterparts, such as cast metal or stone, meaning Tough 2000 resin is the strongest and most rigid material in our functional family of strong and durable resins. Choose Tough 2000 resin to prototype strong, sturdy parts that don't need to bend easily.

Epoxy resin is a special substance with particularly strong properties. This resin is known for its chemical resistance and excellent adhesive qualities. If you need a very durable resin product, then epoxy is the best option to consider. Due to its strong finish and good adhesion qualities, this resin is ideal for a wide range of applications.

Safety Data Sheets (SDS) are current for all resin products and follow the latest government guidelines. Despite the limitations, there are many reasons why product teams would opt for SLA resistant resins instead of standard resins. Here is a complete breakdown of SLA resistant resins, plus some of the major brands of SLA resistant resins that product teams should consider using. Epoxy hardeners can be toxic, while epoxy resins are classified as irritants, so it's best to avoid getting the epoxy adhesive too far on the skin.

But if you make resin ornaments using molds other than traditional ornament molds, they can be heavier, since they would be a little bulky. Unlike epoxy, polyester is not weakened by UV exposure, so ultraviolet curing can be applied to polyester resin, eliminating the need to measure and mix catalytic chemicals. The main difference between normal resin and resistant resin is tensile strength, with a hard resin having approximately twice the tensile strength of normal resin. As such, standard resins are commonly used for projects where aesthetics are more important than performance.

When purchasing any type of resin, it's important to know that resin manufacturers sell their products predominantly to large industrial customers. In Tom's test, he used Elegoo transparent red ABS resin and Prusa garnet “Tough resin”, and the results speak for themselves. Therefore, resins come in a wide variety, ranging from thin layer coating resins to liquid casting resins to produce completely solid plastic components. So even if you wear large quantities, the standard size of resin jewelry would be lighter than a standard size metal jewelry in all respects.

Below is a brief summary of the main types of resins you can expect to find and what you should consider when using them. The results were not surprising at all because the standard resin measured 23.4 MPa, while the hard resins measured 46 MPa for Foamlab, 55 MPa for eSun and 44 MPa for Siraya Tech.
