In the Covid-19 pandemic, face masks are the main protective equipment from potential virus exposure. However, the use of single-use masks contributes to the accumulation of waste and has the potential to become the next threat. An alternative solution to avoid plastic contamination due to the use of masks is the technology of recycling mask waste into thermoplastic products, such as 3D Printingfilament products. The purpose of this study was to identify the thermal and microstructural characteristics of various types of disposable masks (surgical, duckbill, KF-94, and mixed masks) compared to conventional 3D printing filaments, namely Polylactic acid (PLA), Acrylonitrile butadiene styrene (ABS), and Polypropylene (PP). The mechanical properties test carried out is tensile strength. The results show that recycled mask materials can be used as an alternative to PP-based 3D printing filament raw materials. Mechanical testing and statistical analysis of Fisher's least significant difference (LSD) at a 95% confidence interval showed that the average tensile strength of duckbill and mixed masks were not significantly different from PP material, 30.23; 29.38; and 30,54 N/mm2 respectively.
