In-operando fault monitoring during laser melting of metallic powders for advanced manufacturing

在过去的五年中，3D打印领域取得了巨大的进步，以促进快速原型设计和/或复杂零件的制造。我们的行业合作伙伴是金属零件3D打印领域的知名领导者，主要服务于航空航天领域的客户，因为他们需要高性能的组件，但只有非常低的制造量。**FusiA Impression 3D msamtal Inc.是加拿大复杂高性能金属零件增材制造的领导者，特别为航空航天领域设计。与我们的合作伙伴密切合作，我们建议设计，构建和测试一个定制的监控系统，安装在商用级3D打印机上。当激光诱导金属粉末熔化过程中出现错误行为时，该系统将寻求检测并提醒机器操作员。反过来，这些警报可用于(1)干预**并及时纠正过程异常和/或(2)完全停止打印过程并节省宝贵的机器时间。因此，视觉系统将直接安装在商用打印机上，以监控来自已内置视觉系统的实时摄像头馈送。使用这种方法，将不需要以任何方式改变打印机的硬件或软件。除了简单之外，这种方法还将使我们的解决方案**与更广泛的商业3D打印机兼容。反过来，这个附加组件可以帮助**显着提高金属3D打印解决方案的效率和竞争力。

In the last five years, tremendous advances were made in the field of 3D printing to facilitate rapid prototyping**and/or manufacturing of complex parts. Our industry partner is an established leader in the 3D printing of**metallic parts, mostly serving customers in the aerospace sector as they require high-performance components**but only very low manufacturing volumes.**FusiA Impression 3D Métal Inc. is a Canadian leader in additive manufacturing of complex high-performance**metallic parts, especially designed for the aerospace sector. In close collaboration with our partners, we**propose to design, construct and test a customized monitoring system to be mounted on a commercial-grade 3D**printer. This system will seek to detect and alert machine operators when faulty behaviors occur during**laser-induced melting of metallic powders. In turn, these alerts could be indicators used to either (1) intervene**and correct process anomalies in a timely manner and/or (2) to stop the printing process altogether and save**precious machine time.**As such, a vision system will be mounted directly on the commercial printer to monitor the live camera feed**from the already built-in vision system. Using this approach, there will be no need to alter the printer's**hardware or software in any way. In addition to its simplicity, this approach would also make our solution**compatible with a wider array of commercial 3D printing machines. In turn, this add-on could help**significantly increase the efficiency and competitiveness of metal 3D printing solutions.
