Design and Analysis of 3d Printer Using Reinforced Natural Fiber Filament

Mechanical Engineering

3D printer technology is commonly known as additive manufacturing.it is a process of creating three-dimensional (3D) object from digital model created using design software such as CAD and CREO, this digital model sliced in slicing software to generates G codes. These G codes command the printer how to move, printer speed, layer thickness and temperature of the extruder. Conventional filament like PLA and ABS are synthetic polymer pose an environmental challenge because of their non-biodegradable nature. in recent years, research have exploded the use of reinforced natural fiber filament such as jute, bamboo, hemp and flax. natural fiber obtains from animals and plant, giving sustainable biodegradable alternative to synthetic fiber. this natural fiber combines with thermoplastic polymer matrix mostly polylactic acid (PLA) with natural fibers like hemp, bamboo, flax. use of natural fiber reduces environmental impact, improve sustainability and provide unique surface aesthetic however this filament also possesses some challenges during printing such as nozzle clogging, uneven extrusion and increase wear on printing components also it reduces tensile strength, increase brittleness. Moisture sensitivity. Thermal stability of natural fiber filament is lower compare to pure polymer. It also shows the lower thermal degradation than synthetic polymers that constrains processing temperature during processing 3D printer. Current research in material science and engineering focus on developing fiber matrix compatibility through coupling agents, surface modifications, and the incorporation of nano-scale reinforcements using cellulose nanofiber It commonly used in textile and various industry. This research aims to design and analyze a 3d printer system optimized for reinforced natural fiber filament
