| Summary: | Open-source 3D printer has been widely used for fabricating three dimensional products. However,
this technology has some drawbacks that need to be improved such as accuracy of the finished
parts. One of the factors affecting the final product is the ability of the machine to extrude the
material consistently, which is related to the flow behavior of the material inside the liquefier. This
paper observes the pressure drop along the liquefier by manipulating the nozzle die angle from
80 to 170 using finite element analysis (FEA) for polymethylmethacrylate (PMMA) material. When
the pressure drop along the liquefier is varied, the printed product also varies, thus providing less
accuracy in the finished parts. Based on the FEA, it was found that 130 was the optimum die angle
(convergent angle) for extruding PMMA material using open-source 3D printing. |
