目前针对该开源型3D打印机打印产品的力学性能研究还相当的缺乏,无法满足工业或者受力部件的打印指导.本文为验证RepRap原型打印机或者其衍生版本打印机的真实受力环境可用性,对其打印的部件进行了基本的力学性能测试,从而得到能够反映其打印质量的拉伸强度、延伸率以及弹性模量,进而对该类型3D打印机用户提供打印标准及指导.根据实验结果,ABS和PLA材料打印试样的平均拉伸强度分别为28.2 MPa和58.1 MPa,所对应的平均弹性模量为1533 MPa和3500 MPa.通过与商用打印机打印试样的力学性能结果对比,可以明显看出开源型打印机不仅在结构建造上面具有可调谐,组装成本低的优点,并且其在力学功能性方面也有其可比较性.

At present, it is rare about the research on the mechanical properties about the 3D printed parts, which barrier its usage in engineering applications. In this study, based on the original RepRap and its variants, basic mechanical properties including tensile strength, elongation and elastic modulus, are quantified using realistic environmental conditions to pro-vide standards and guide for 3D printer users. According to the test results, ABS holds an average tensile strength of 28.2MPa and elastic modulus of 1533MPa, while those of PLA are 58.1 MPa and 5300MPa respectively. In the addition, the comparison with commercial printers clearly identifies not only open-source printers owns superior of low-cost, tuned and diversity, but also can be considered as mechanically functional as commercial ones.
