University of Toronto researchers test short fiber composites in SLA 3D printing

3D printing is still relatively unknown, and as we look for the most affordable, rugged, and durable materials and components, mechanical performance issues abound. Now, researchers at the University of Toronto are studying the choice of short fiber composites for SLA 3D printing. Their findings were recently published in “Mechanical Analysis of Short Fiber Composites Fabricated by Inverted Stereography” by Ignace (Joe) Brada, a student in chemical engineering and applied chemistry.

Brada recognizes that many 3D printed components are not suitable for carrying applications due to lack of mechanical properties. To improve this problem, he combined glass fiber with acrylic for SLA printing. Brada has succeeded in increasing the modulus of elasticity but has challenged other aspects. He chose SLA 3D printing because there are many benefits to making a powerful prototype, although there are other issues, such as the amount of resin needed to fill the can (corresponding to the volume of the can), which can be cumbersome. It is also inconvenient to pour the surrounding resin to get rid of the partially cured material.
