Abstract

3D printing is a process of making three-dimensional solid objects from a digital file process created by laying down successive layers of material until the object is created. Many filaments can be used in 3D printing, one of which is PETG (PolyEthylene Terephthalate Glycol). PETG is a modification of PET (PolyEthylene Terephthalate) with added glycol at a molecular level to offer different chemical properties that provide significant chemical resistance, durability, and excellent formability for manufacturing. This study aims to find the most optimal parameter of surface roughness of PETG with different parameters of nozzle temperature, infill geometry, layer height and fan speed. Taguchi L16 (44), with four levels for each parameter, was used to determine the effect of each parameter. Each experiment was repeated five times to minimize the occurrence of errors. Based on the result, the effect of each parameter is nozzle temperature at 4.9%, infill geometry at 5.9%, layer height at 82.3%, and fan speed at 4.6%. Layer height has the highest effect on surface roughness, and other parameters have a low effect, under 7%. Research shows that the optimal combination of parameters is a nozzle temperature of 220 °C, infill geometry zig-zag, layer height of 0.12 mm, and a fan speed of 80 %.

Abstract

Liquefaction is a natural disaster that cannot be predicted. Therefore a simulation tool is needed to determine the characteristics of the disaster, so that it can be reduced. This simulation tool moves on the x-axis and y-axis with the drive system using a hydraulic system. The purpose of this research is to measure the vibration parameters that arise in the liquefaction machine. In addition, to analyze the vibration system that arises in the liquefaction machine on the x-axis and y-axis. And the analysis method used is experiment. This mechanism is designed in 2 levels using 6 rollers on each floor. The speed and acceleration of the drive mechanism are able to describe the true state of liquefaction.
