Design, analysis and fabrication of filament extruder

Additive manufacturing or popularly known as 3D printing is the latest 3D printing technologies that have been widely used by various big sectors such as manufacturing, healthcare, education, aerospace, electronics and small-scale industries including individual or home users for their finished product, sample or as conceptual design. 3D printing is a process in which products are made by using material such as plastic or metal by layering on one after the other, creating a three-dimensional object. This printing process will eventually create a waste material that is proven to contribute to our environmental pollution. The solution needed is to recycle the waste materials. However, currently, the recycling machine used for extruding this 3D printer filament is normally very expensive and large unsuitable for all places specifically for individuals, laboratory, university or small medium enterprise/manufacturer. Therefore, this project proposal's main objective is to design, analyze and fabricate a low-cost 3D printer filament extruder as proof of concept. The methodology used is to study existing models and redesign with computer-aided design software prior mechanical & electrical fabrication and commissioning. This project is expected to successfully build the low- cost filament extruder to recycle the 3D printing waste materials which may be helpful to our sustainable environment, minimize the filament consumption cost and affordable to individual or home users.
