Abstract

Fused Deposition Modeling (FDM) is one of the most popular 3D printing technology that used at academic and business purposes due to the easiness of the manufacture process that it held. But, one of the most major problems that usually occur in the industry is the frequentness of damaged and deficiency on the result of printing, especially when it is printed using the ABS filament. Although, ABS is one of the filaments which has a lower cost compared to others, but has a bigger value per gram on the printing sectors compared to PLA filaments. It could be a good business prospect if it can be handled on the problems. Therefore, the knowledge on how to prevent the problems, and finding an efficiency on the various of infill pattern, would be one of the key of success in this industry. In this article, a research on finding optimum parameters against the time and quality of the product using the Taguchi method, and also ASTM D-638 is also needed to find the best infill pattern against the tensile strength that an ABS filament have on the mechanical properties. As a result, the parameters, nozzle temperature and bed temperature have a small impact on producing time, but have a greater impact on the quality of printing product. Besides, the infill pattern which has the biggest tensile strength on smaller density is Trihexagon. Meanwhile, the Lines infill has the biggest standard of deviation, which endure the most stress on the bigger density compared to Triangles and Trihexagon.

Abstract

Currently, many innovations are being made in developing a technology to facilitate human work. One of these technologies is the hydraulic cylinder. Hydraulic cylinders were created to facilitate human work, especially in the industrial sector. Hydraulic cylinder, using a liquid or so-called liquid fluid, to be able to make the hydraulic cylinder work. In the hydraulic cylinder components, there are cylinder axles, pistons and cover seals. In general, hydraulic cylinders can be used for wingboxes. A wingbox is a box on a truck, which can be opened from the side with the help of a hydraulic cylinder. This journal was created to study how the simulation of hydraulic cylinder components when working. The design method used is the reverse engineering method, where the components that have been designed are then simulation is made to find out how strong the component is in holding the load when the component is working. The simulation is carried out using the Autodesk Fusion 360 application to find out how strong the hydraulic cylinder works in bearing the load. The results of this method are obtained when the simulation results of the hydraulic cylinder have been obtained.

Abstract

Coolant Filtration Machine is one of the products of PT. Matahari Megah. The purpose of this machine is to recycle residual coolant fluid that has been used in the machining process. Coolant Filtration Machine is working through automation system which involves conveyor system controlled by sensors. The components involved need to be analyzed and calculated properly to work as designed. Hence, calculation for required electricity power to move the wire mesh conveyor used in this machine was done. According to the process, it was concluded that the required power is 60 Watt. A pair of sensors are mounted to control the movement of this conveyor are proximity sensors which monitor the water container and lever limit switch monitoring the paper holder system.
