Additive manufacturing using commercially available 3D printers gives us the ability to quickly produce and iterate our designs. Since we are using these end use products, it is critical to understand the consequences of using such machines and associated materials. This week, we focused on understanding the effect temperature has on two types of common 3D printing filaments, PLA and PETG. PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) filaments are the most popular forms…
