Abstract

As the technology in this world has evolves rapidly, the 3D printing is not excluded from the growth as well as becoming one of the most postulate method in manufacturing process. Opposite to the standard manufacturing process which commonly is subtractive that produces a lot of waste, 3D printing is way friendly to the environment. Application of additive manufacturing method in 3D printing leads to less or no wasted materials. For this promising technology, it still developing especially when there are lot of open source medium for people to access and discover the 3D printing technology. There is always a problem in every human-made creation. As for 3D printing, consumption of plastic materials has significantly increase due to high demand in market. In order to minimize the negative impact of plastic waste to the environment, a study on designing an integrated 3D printer recycle machine is done. Engineering design method is used to formulate and develop new concept design. Identification of current problems on the existing recycle machine is done to make design improvement on the new recycle machine. For the guideline of developing the recycle machine’s design, preliminary result from three conceptual designs are used. There are three main components of the recycle machine which are shredder, hopper and extruder. For this study, its focus is on the hopper and extruder due to the objective on having success extrusion of filament. By using CATIA software, analysis has been made on the components and the assembled product. A prototype is built from 3D printed parts and reuse materials. Analysis of extruded filament was done for every 10 cm with minimum of 10 repetitions. Percentage of error for diameter of filament indicates 1.84mm diameter with 5.14% as the lowest error while diameter of 1.90mm with 8.57% as the highest error. So the objective to get below than 9% of percentage error is achieved and it gives hope for future improvement in this project of recycling waste of ABS polymer.
