Multimaterial 3D printing of biocomposite materials

Résumé

Additive manufacturing is a promising and disruptive technology that is being applied in many industrial sectors, such as aeronautics, robotics, and bioengineering, because of the ease of use and high level of customizability that it offers. Additionally, biocomposite materials are being seen incorporated more frequently in industry because of favourable properties such as being recyclable, biocompatible, biodegradable, having low environmental impact, and comprising of naturally abundant materials. In this study, multimaterial 3D printing involving a PLA/hemp biocomposite and pure PLA was done, with the focus being on keeping the bulk of the part as the biocomposite material and adding a PLA covering to the outer surface to explore the compatibility of the two materials being printed together and the effect on the mechanical properties. Contact angle measurements and immersion testing were done to see the effect of the hemp biofiller on the way the PLA interacts with moisture and compression testing was done to compare the performance of the samples in a dry and wet state. Optical and x-ray imaging techniques were used to closely examine the final printed specimens and give insight to the results of the testing.
