3D Printing has gained popularity over the years for its improved affordability and great versatility. There is a wide variety of 3D printing technologies and a wide spectrum of materials that could be 3D printed, ranging from metallic to nonmetallic. Fused deposition modelling (FDM) has emerged as the most common technology used in desktop/home 3D printers and it is most typically used for printing thermoplastics such as acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA). High density polyethylene (HDPE) is a thermoplastic widely used for packaging. The sheer availability of recycled HDPE (rHDPE) from used packaging encourages efforts to apply it in 3D printing, in particular FDM printing.
