成果简介	NOVELTY - Synthesis of organic three-dimensional (3D) filament for 3D printers involves (i) collecting food waste and placing in an anaerobic chamber, restricting oxygen supply, lowering temperature to prevent growth of bacteria and decomposition of food waste; (ii) draining excess water from food waste by a sieve installed at a bottom portion of chamber, following by addition of antioxidant for enhancing decomposition rate of said food waste, obtaining decomposed food waste; (iii) cutting decomposed food waste into small pieces, subjecting food waste to oven drying, sun drying, and UV drying for drying food waste, eliminating remaining water and bacteria from dried food waste; (iv) grinding food waste, obtaining powdered food waste, keeping powdered food waste in silica compartment, completely eliminating moisture and foul odor from food waste; (v) mixing a reinforcing agent in powdered food waste for a time duration in the range of 2-3 hours. USE - Method for synthesis of organic 3D filament for 3D printers. ADVANTAGE - The method prepares 100% biodegradability three-dimensional (3D) filament composed of food waste. The polylactic acid (PLA) provides mechanical strength to filaments and polyvinyl alcohol (PVA) imparts flexibility to filaments. The dye and fragrance imparts color and a pleasant odor to filament. The product breakdown over time without harming the environment and promotes the responsible waste management and eliminates the need of extended recycling processes. The strength and durability of the filament is enhanced due to the incorporation of a reinforcing agent (dried sugarcane waste) which improves the internal structure of the filament. DETAILED DESCRIPTION - Synthesis of organic 3D filament for 3D printers, which involves (i) collecting food waste and placing in an anaerobic chamber, restricting oxygen supply, lowering temperature to prevent growth of bacteria and decomposition of food waste; (ii) draining excess water from food waste by a sieve installed at a bottom portion of chamber, following by addition of antioxidant for enhancing decomposition rate of said food waste, obtaining decomposed food waste; (iii) cutting decomposed food waste into small pieces, subjecting food waste to oven drying, sun drying, and UV drying for drying food waste, eliminating remaining water and bacteria from dried food waste; (iv) grinding food waste, obtaining powdered food waste, keeping powdered food waste in silica compartment, completely eliminating moisture and foul odor from food waste; (v) mixing a reinforcing agent in powdered food waste for a time duration in the range of 2-3 hours, enhancing the internal strength and durability of the food waste, obtaining a mixture, and mixing poly lactic acid (PLA), polyvinyl alcohol (PVA), rosin, fragrance, and industrial dye with mixture, obtaining a thick solution, extruding solution through a nozzle at a pressure in the range of 8-12MPa and at 120-150 °C, and obtaining organic 3D filament.
