摘要

The demand for a novel and sustainable alternative materials for 3D printer filaments has been knowingly increasing. One alternative source for the filament is to reuse and recycle post-consumer plastic products, which is also a compelling approach to conserve energy and sustain the environment. Thus, this study is focused on the materials selection of virgin polymer resins and recycled post-consumer plastics for use in 3D printer filaments. A multi-criteria decision method of Elimination and Choice Expressing the Reality (ELECTRE) was utilized to determine the best materials for 3D printer filaments. The study has shown that the virgin low-density polyethylene (LDPE) and recycled polyethylene terephthalate (PET) are optimal materials as an alternative filament among other options such as virgin high-density polyethylene (HDPE), virgin PET, virgin polypropylene (PP) and recycled HDPE. Aside from the different options of the type of materials, the various properties considered in the calculation include tensile strength, melting point, glass transition temperature, melt flow index, coefficient of thermal expansion, and cost. Moreover, a redesigned breadboard was produced thru 3D printing using a recycled PET as filament source.
