ABSTRACT

Biodegradable materials have attracted much attention from researchers due to the pressing need to reduce enduring waste worldwide. Various 3D printed parts were designed and printed using polylastic acid (PLA) filament as feedstock. Various 3D printed electrical parts were designed and printed using polylactic Acid filament as feedstock. The parts were designed using Solid works and were printed using an FDM 3D printer. An experimental test was carried out on samples of the printed materials; Hardness, Differential scanning calorimetry, Tensile strength, Flexural strength, Density,Thermalgravimetric analysis and Fourier Transform Infrared Spectroscopy (Ftir) were determined from the experiment. Heating effect on PLA plastics affects the mechanical properties of the material produce. The results gotten from the experiment were compared with that of the standard values of each parameters. This development will solve two major problems; plastic waste management and production of locally manufactured 3D printing feedstock (which is presently the greatest challenge of 3D printing in Nigeria). This innovation is particularly useful to manufacturing firms and will reduce spare parts importation. Scraping of machines/equipment due to non-availability of parts will also reduce considerably. Thus, facilitating the achievement of sustainable development goals with respect to industry, innovation and infrastructure.
