The Effect of Parameters on the Process of Making Objects with Rapid Prototyping Digital Light Processing Technology on the Bending Stress

Abstract

The world is currently entering the era of the industrial revolution of 4.0. The era in which the occurrence of disruptive technology. The main purpose of this existence of the industrial revolution to create stability in the distribution of goods and necessities. Broadly speaking, there are some benefits that can be posed by the presence of the industrial revolution 4.0 is encouraging research, customization, and optimization. In addition, there are several challenges to be faced in the industrial revolution was the first IE 4.0 security, the second is the capital, and then a third that is employment, and the fourth is privacy. A method that can respond to these challenges is additive manufacturing using SLA-DLP 3D Printing. The making of objects utilizing CAD data that have been made in advance. This research aims to know the effect of object making process parameters with digital light processing rapid prototyping technology on bending stress. The parameters investigated is the layer thickness and the exposure time. Test specimens made of a material with liquid photopolymer resin refer to ASTM D 790 using SLA-DLP 3D Printer. Measurement results in data analysis using ANOVA design with type 2 factorial design model and level 1 factorial interactions assisted by software Design Expert trial version. The results of the ANOVA is known that factors significantly (α = 0.001), to effect of object making process parameters with digital light processing rapid prototyping technology on bending stress., that are the layer thickness=10%, exposure time=2%, interaction layer thickness and exposure time=87%.

The Effect of Parameter Process 3D Printer Technology Digital Light Processing to Geometric of Shaft

“…In the printing process, there are several parameters such as Layer Thickness, Exposure Time, Overhang Angle, Hatch Spacing, the Fill spacing, Hatch Overcure, Border Overcure, and the Fill Cure Depth. The Parameters are the crucial part for greatly effects of accuracy and strength level of each layer, therefore selection and setting of these parameters is very important [4]. In the world of machining, the functional characteristics of a machine component will be obtained after the component was assembled with its partner components, to get good functional characteristics the good geometric are needed [5], so the correct alignment and roundness can reduce vibrations and more efficient to use and extend the lifetime product.…”
