阿尔斯托姆是一家总部位于法国的滚动股票制造商，已采用FDM 3D打印技术Stratasys简化运输部门的备件生产。
One of the company’s most recent projects involved producing a set of emergency spare parts for Algeria’s Sétif Tramways, and additive manufacturing was the star of the show. Leveraging Stratasys F370 3D printers, Alstom was able to drastically slash lead times and save Sétif Tramways thousands in manufacturing costs, reducing downtime in the city’s 14-mile transport network.
“ 3D打印给我们的敏捷性对阿尔斯通作为一家企业至关重要，”阿尔斯托姆添加剂制造计划经理AurélienFussel说。雷电竞充值“在我们的客户依靠零件来维护运营的地方，拥有这种内部生产能力意味着我们可以绕过我们的传统供应链，并迅速，成本效益，以解决他们的需求。”
From 45 days to 48 hours
在发现其电车前大灯因水和碎屑的积累而受到内部破坏之后，塞蒂夫市接近了阿尔斯通寻求帮助。具体而言，该市的电车道需要定制的备件，以塞在电车的大灯组件中的小孔中，以防止进一步损坏。
Alstom将其专用的3D打印轮毂踢到齿轮上，启动了F370 FDM系统，并在短短48小时内设计了3D打印，并提供了十二个橡胶排水塞。使用传统的制造技术，这些零件通常需要大约45天才能生产。
此外，在这种情况下，使用3D打印还将Sétif的固定制造成本降低了约80％，从而节省了大约6,000欧元。这可以归因于缺乏工具，降低人工成本以及避免长期45天的交货时间来幸免的成本。
“We avoided the minimum three-week production lead-time typically required of traditional manufacturing methods and ensured the tram network’s operations were minimized,” adds Fussel. “For our transportation customers like Sétif, every minute of lead time within a network means lost revenue, so every minute we can win back when solving maintenance issues reduces that loss.”
物质选择的重要性
根据Alstom的巴塞罗那3D打印中心经理Jaume Altesa的说法，该项目的成功在很大程度上取决于Stratasys 3D打印技术的广泛材料能力。当涉及到运输等重工业的应用时，强大的3D打印材料具有应对高应力和其他极端条件所需的特性至关重要。
“Having production-grade materials is essential to providing our customers ready-to-install 3D printed parts for use on vehicles,” explains Altesa.
对于Sétif电车项目，Alstom采用了一种非常耐用的弹性材料，称为FDM TPU 92A。灯丝提供了柔韧性，耐磨性和耐撕裂性的结合，使其成为排水塞的理想选择。
“As we’ve seen during COVID-19, in some regards 3D printing has had its watershed moment, with more and more manufacturers embracing the technology to increase their production agility and reduce supply chain dependency,” concludes Yann Rageul, Head of Manufacturing Business Unit for EMEA at Stratasys. “As a longstanding customer of ours, Alstom is a shining example for these companies having pioneered the use of additive manufacturing for spare part production for many years.”
对于Alstom等公司，3D打印自定义替换零件而无需高成本或冗长的交货时间是一个改变游戏规则的能力。就在上个月，汽车公司戴姆勒AG及其服务品牌Omnipluscreated a mobile 3D printing center specifically for thedecentralized production of spare parts。The mobile container will be in operation at the BusWorld Home (BWH) service center in Hamburg, and can be transported by truck to any location.
沿着软件路线，法国国家铁路公司，SociétéNationaledes Chemins deFrançais（SNCF），最近宣布采用3D打印软件开发人员3您的敏捷PLM软件。In a bid to cut costs and streamline on-demand spare part production, SNCF will use the Digital Qualified Inventory platform to identify, evaluate, and store its additive manufacturing part data.
