The influence of nano and micro SiO2 particles on the mechanical behavior of 3D printed samples

Digital light processing (DLP)-based 3D printing employs projection light to polymerize materials to produce the pre-designed structures. However, in many cases, adjusting the mechanical properties is an option to use them in a wide range of applications. This study evaluated modulus, strength, and elongation at break of fabricated samples to understand the effect of adding fillers to the methacrylate resin. The results indicated that in all samples, using SiO2 fillers advanced the modulus and reduced the elongation at break compared to the pure sample.
