风洞模型传统上由高质量的金属材料加工而成;这种情况降低了测试不同几何变化或模型的可能性，因为它对应于增量成本。在过去的十年中，增材制造技术的质量一直在逐步提高，而成本一直在下降。3D打印技术的利用表明有可能提高风洞模型生产的成本、时间和灵活性。可能存在的缺点，在质量方面的模型整理，刚度和几何精度进行了调查，以了解生产技术是否能够提供一个合适的测试设备。此外，在打印过程中集成了用于稳定表面压力测量的压力孔，并且复杂三维大后掠机翼的生产已被选为目标。利用计算流体动力学工具来确认实验结果，根据最佳实践方法表征由前缘涡主导的流动模式。研究了实验数据的逼真程度，为科学研究所描述的流场。最重要的指导方针和可能的改进的洞察力，以及该方法的主要特点。
Wind tunnel models are traditionally machined from high-quality metal material; this condition reduces the possibility to test different geometric variations or models as it corresponds to incremental cost. In the last decade, the quality of additive manufacturing techniques has been progressively increasing, while the cost has been decreasing. The utilization of 3D-printing techniques suggests the possibility to improve the cost, time, and flexibility of a wind tunnel model production. Possible disadvantages in terms of quality of the model finishing, stiffness, and geometric accuracy are investigated, to understand if the production technique is capable of providing a suitable test device. Additionally, pressure taps for steady surface pressure measurements are integrated during the printing procedure and the production of complex three-dimensional highly swept wings have been selected as targets. Computational fluid dynamics tools are exploited to confirm the experimental results in accordance with the best practice approaches characterizing flow patterns dominated by leading-edge vortices. The fidelity level of the experimental data for scientific research of the described flow fields is investigated. An insight of the most important guidelines and the possible improvements is provided as well as the main features of the approach.
