 This research work came to develop Fused Deposition Modeling, FDM, Feet Stock Filament Wire from Recycled Low-Density Polyethylene, LDPE, with different particle sizes of SICK, UL-203 as reinforcement, and found that UL-203, based double particle size, DPS, reinforcement resulted in better mechanical properties and dimensional stability with improved surface hardness. The results were supported by SEM-based photomicrographs and DSC. This article was offered by Piyush Badi, Rupinder Singh, and IPS Ahuja.
