The goal of this case study is to optimize the production of SLS suitable fine powders of sustainable biopolymers and directly assess their printability. Among the biopolymers, PLA is the most widely used in the Fused Deposition Modeling (FDM) hobbyist and enthusiast markets, whereas more invasive polymers such as PA12 are commonly used in Selective Laser Sintering (SLS), the most common 3D printing technology for the production of functional parts. A higher demand for biopolymers in the SLS industry is expected in the near future - following the general sustainability goals of all industries - as the technology allows for the production of more complex geometries and intricate details, as well as ad-hoc parts for the medical industry, where the use of biopolymers is already widespread.
