摘要: 以3D打印制造的汽车空调开关座样件为研究对象, 利用3D打印技术制作样件, 探讨3D打印样件在汽车零/部件新产品试制中的可行性。对比分析了3D打印样件与注射成型的工程样件(Off Tooling Samples, OTS)工艺流程的差异, 体现了3D打印样件的无模制造特点。参照QC/T 15—1992《汽车塑料制品通用试验方法》等有关国家及行业标准, 结合材料强度理论, 通过试验验证了3D打印样件的力学性能和耐温特性。分析试验结果, 找出了3D打印样件与OTS样件及常规ABS塑料在拉伸、弯曲和冲击性能方面的差异性。研究结果表明, 与OTS样件比较, 3D打印样件在拉伸、弯曲和冲击性能方面还存在一定的差距, 提出了3D打印样件用于新产品开发过程中的外观效果评估、工艺验证、尺寸及功能验证的建议。

Abstract: Taking the car air conditioning switch base sample by 3D printed as object, to make samples using 3D printing technology.The feasibility of the 3D printing sample in the trial-manufacture of auto parts new products is discussed.The difference of technological process between the 3D printing and injection molding Off Tooling Samples(OTS)samples is comparative analyzed, the characteristics of the model free manufacturing for 3D printing sample are reflected.Referring to relevant national and industry standards of QC/T 15—1992 “general test method for automotive plastics products”, etc.Combining material strength theory, the mechanical properties and heat resistance of the 3D printing samples have been verified by experiment.Analyzing the experiment results, the difference of properties in tensile, bending, impact finding was found between 3D printing samples and OTS samples as well as normal ABS plastic.The results show that, the 3D printing samples still have a certain gap in tensile, bending, impact compared with the OTS sample.Finally, 3D printing samples for appearance effect evaluation, process validation, size and function verification in the new product development process are proposed.

Key words: air conditioning switch base, 3D printing, OTS samples, process, performance test
