In the present scenario, 3D printing plays an important role in manufacturing engineering and product design and development. In terms of the quality of the product in the 3D printing process, the filament plays a vital role. At present, the majority of the 3D printing components are produced with commercial filament available on the market. The properties and characteristics are restricted by the availability of the filament on the market. A tailored filament gives a promising solution; hence, the present work on a tailored composite filament is fabricated and characterized by its tensile properties. The base matrix material is selected as ABS, and death snail shell powder reinforcement is considered. Reinforcement with and without hydrothermal decomposition is considered. The ABS, ABS with and without reinforcement are fabricated using a mini filament extruder, and the results are compared.
