如今,众所周知,在船上,自由空间是一个溢价。不幸的是,船上的每个部件都有故障前的持续时间,和备件占用空间。当发生故障时,必须更换损坏的部件,以维持船舶的运行。开发3D打印机技术和特定材料技术,它已经成为可能打印一个备件,可以更换损坏。然而,由于危险环境(盐,湿度,湿度振动,等。),打印部件会改变其属性。电容和另外的介电常数是必须被监测的参数或度量,因为其直接影响打印部件材料结构。因此,本文旨在研究由于危险环境而改变填充模式和密度后,增材制造中的相对介电常数对印刷船舶备件的影响。实验,其中创建了三个成形材料样本,由以下设备组成,UltimakerS53D打印机,聚乳酸(PLA)和丙烯腈-丁二烯-苯乙烯(ABS)材料,和LCHM8018m。结果表明,PLA的相对介电常数变化在1.7778和2.8141之间,ABS的相对介电常数变化在2.1979和2.9989之间,取决于填充密度和图案。进行ABS的ANOVA测试以研究计算的介电常数如何与各种填充形状的填充密度相关。分数为:F=154.3773,Fcrit=5.1432,p=6.9269·10-6。PLA的ANOVA检验得到分数F=18.911,Fcrit=5.1432,和p=0.0022。
Nowadays, it is well known that on the ship, free space is at a premium. Unfortunately, every part on the ship has its duration before the failure, and the spare parts occupy the space. The broken part must be replaced when the failure occurs to maintain the ship\'s operation. Developing 3D printer technology and particular material technology, it has become possible to print a spare part that can replace broken. However, due to hazardous environments (salt, humidity, vibrations, etc.), printed parts change their properties. Electrical capacity and further dielectric permittivity is a parameter or metric that has to be monitored since it directly influences the printed part material structure. Therefore, this paper aims to research the impact of relative dielectric constant in additive manufacturing on printed ship\'s spare parts since infill patterns and density were changed due to a hazardous environment. The experiment, in which the three shaped material samples are created, consists of the following equipment, the Ultimaker S5 3D printer, Polylactic Acid (PLA) and Acrylonitrile-Butadiene-Styrene (ABS) materials, and LC HM 8018 m. Results show relative dielectric constant changes between 1.7778 and 2.8141 for PLA and between 2.1979 and 2.9989 for ABS, depending on infill density and pattern. ANOVA test for ABS is performed to investigate how the calculated dielectric constant relates to the infill density for various infill shapes. Scores are: F = 154.3773, Fcrit = 5.1432, and p = 6.9269·10-6. ANOVA test for PLA resulted in scores F = 18.911, Fcrit = 5.1432, and p = 0.0022.
