Abstract
Mechanical properties problems that are closely related to the strength of 3D printed products generally occur during the development of 3D printing machines, In which several components used are the results of additive manufacturing technology. The damages generally occur in the components that receive force and the damage is in the form of cracks and fractures. The focus of this study is to determine the effects of increasing the value of fill density on mechanical properties, especially tensile strength and strain with carbon fiber filament material. This study used an experimental method using two types of filament material: nylon carbon fiber and PLA carbon fiber with a diameter of 1.75 mm for each filament and a recommended printing temperature of 190-260°C. Both types of filaments were printed using a direct extruder type 3D printing machine with a build size of 180 mm x 180 mm x 180 mm and printing was carried out at atmospheric pressure and a horizontal printing area. The Universal Testing Machine carried out mechanical properties testing implementation related to tensile strength and strain. Based on the results of experiments and tests that have been carried out, the strain values are 16.970 – 26.681% and the tensile strength is 19.244 – 23.899 MPa for nylon carbon fiber filament material. Whereas the PLA carbon fiber filament material, the strain value is 7.673 – 15.546%, and the tensile strength is 18.580 – 24.552 MPa. Therefore, based on the test results, it is known that the fill density parameter value has an influence on the strain value and tensile strength so that it can be used as a reference in setting machining parameters.
与3D打印产品强度密切相关的机械性能问题通常发生在3D打印机的开发过程中,其中使用的几个部件是增材制造技术的结果。损伤通常发生在受力的部件中,并且损伤以裂纹和断裂的形式出现。本研究的重点是确定增加填充密度对碳纤维长丝材料的力学性能,特别是拉伸强度和应变的影响。本研究采用了一种实验方法,使用了两种类型的细丝材料:尼龙碳纤维和PLA碳纤维,每条细丝的直径为1.75 mm,建议印刷温度为190-260°C。使用构造尺寸为180mm x 180mm x 180 mm的直接挤出机型3D印刷机印刷这两种类型的细丝,并且在大气压和水平印刷区域下进行印刷。万能试验机进行了与抗拉强度和应变相关的机械性能测试。根据已经进行的实验和测试的结果,应变值尼龙-碳纤维长丝材料的拉伸强度为19.244–23.899 MPa。而PLA碳纤维长丝材料的应变值为7.673–15.546%,抗拉强度为18.580–24.552MPa。因此,根据测试结果,已知填充密度参数值对应变值和抗拉强度有影响,因此可以作为设置加工参数的参考。
