背景：呼吸防护装置的主要功能是在环境和使用者之间提供完整的物理屏障。为了确保这一点，无论用户的个人面部特征如何，面罩与用户面部的密封性都是至关重要的。 目的：本研究的主要目的是评估使用 3D 扫描和 3D 打印技术开发适合用户面部人体测量尺寸的定制呼吸器的可能性，并评估这种定制设备的防护、使用和强度参数。 方法：市售双过滤半面罩类型选择 MP22/2 作为定制的基础型号。使用 ATOS Core 光学 3D 扫描仪对半面罩面罩进行 3D 扫描。同时使用手持式 3D 扫描仪 Artec EVA 对测试对象面部进行人体测量。然后使用 Geomagic Touch X 触觉设备将面罩的数字模型与用户脸部的形状进行匹配。采用选择性激光烧结技术从热塑性聚氨酯中打印出定制面罩。组装后，对呼吸器进行了测试，以确保其符合欧洲标准的要求。结果：事实证明，所开发的呼吸器非常适合使用者的面部，不会造成任何印记或皮肤刺激，并且在防护性、使用性和强度参数方面得到了积极的评估。结论：应用3D扫描和3D打印技术来设计和制造定制半面罩面罩是未来呼吸防护装置发展的可行选择。
BACKGROUND: The main function of respiratory protective devices is to provide an intact physical barrier between the environment and the user. To ensure that, a leak-tight fit of the facepiece to the user's face is essential, regardless of the user's individual facial features.OBJECTIVE: The main objective of this study was to assess the possibilities of developing customized respirators well fitting to the anthropometric dimensions of the user's face using 3D scanning and 3D printing techniques and to evaluate this custom-made device in terms of protective, usage and strength parameters.METHODS: Commercially available twin-filter half-mask type MP22/2 was selected as base model for customization. The 3D scans of the half-mask facepiece were performed using ATOS Core optical 3D scanner. Simultaneously anthropometric measurements of the test subject face were carried out with hand-held 3D scanner Artec EVA. Then digital model of the facepiece was matched to the shape of user's face using Geomagic Touch X haptic device. Customized facepieces were printed out with use of selective laser sintering technique from thermoplastic polyurethane. After assembling, respirators were tested for compliance with the requirements of the European standards.RESULTS: The developed respirators proved to be very well-fitted to the user's face, did not cause any imprints or skin irritations and were assessed positively in terms of protective, usage and strength parameters.CONCLUSIONS: The application of 3D scanning and 3D printing techniques for designing and fabricating customized half-mask facepieces constitutes a viable option for the future development of respiratory protective devices.
