Abstract

Additive manufacturing which also well known as 3D printing have been growing as a new trend in manufacturing technology and one of the main element in Industrial Revolution 4.0. However, the cost of the commercial 3D printers is expensive and mostly affordable by industries only. Hence, open source 3D printers have provided a low-cost alternative for the public to own a personal 3D printer. The objective of this project is to develop and construct a low-cost 3D printer. Besides, this project also aims to compare the performance of the developed 3D printer with the commercial 3D printer. Therefore, sample cubes are printed by both 3D printers as the specimens to be analysed. Several analyses have been conducted including surface roughness analysis, dimensional accuracy analysis and porosity analysis. The results shown the developed 3D printer is superior to the commercial 3D printer in term of surface roughness and porosity while inferior in dimensional accuracy. This shown the developed 3D printer have the potential to outperform the commercial 3D printer at a lower cost. Lastly, the improvement in dimensional accuracy is reported.
