Mechanical characterization of additive manufactured samples from biodegradable materials

Abstract

Abstract One of the biggest challenges facing engineers and designers in the field of additive manufacturing is to constantly develop and promote new products to meet the increasingly varied and demanding needs of customers. They must also “navigate” through a wide variety of technologies and materials available in order to determine the most appropriate solution for their application. The best and easiest way to determine if a particular technology or material is right for an application is to study and understand its behavior. This paper aims to mechanical characterize 3D printed samples from biodegradable materials through tensile, bending, and impact tests but also by determining the mechanical behavior in the dynamic regime and the tribological behavior (friction coefficient and wear). For the obtained results during the tensile test were performed a statistical analysis of the technological parameters’ influence on the output parameters (tensile strength, strain, and modulus of elasticity) and it has been developed and the optimization of these ones. The studied biodegradable thermoplastics were bioFila Linen, bioFila Silk and Fiber Wood which according to the highlighted results can be used in various fields of activity and can easily replacing polymers from fossil resources such as flexible filaments, high impact polystyrene, polypropylene, polypropylene reinforced with short glass fibers, polymers reinforced with metal or wood powder.</jats:p
