Airbussubsidiary and global supplier of aircraft parts,Satairhas provided a U.S. airline customer with what it claims is the “first certified metal printed flying spare part.”
Satair开发了3D印刷的A320Ceo Wingtip围栏，该零件变得无法获得原始供应商，后者遇到了铸件的困难。雷电竞充值除了提高零件生产的灵活性外，还选择了由于有竞争力的成本和交货时间因素，因此还选择了添加剂制造作为替代制造方法。
“我们收到了替换零件的订单，我们的AOG采购部门转向增材制造团队寻求解决方案，” SATAIR HO Addive Manufacturing Felix Hammerschmidt说。雷电竞充值“经过短暂的预评估，该零件被移交给了空客的Rapidspares设计办公室。
“Using a new certification process they were able to re-certify the former cast part within five weeks and adapt it to titanium, which is a qualified airworthy additive manufacturing material.”
3D printing spare parts for aerospace
尽管SATAIR的A320CEO机翼围栏可能是第一个经过认证的金属印刷飞行备件，但在航空航天区域3D打印的其他地方已在原型和功能零件的设计和制造中使用了一段时间。
Earlier this year,Additive Flight Solutions（AFS），3D打印机制造商之间的合资企业Stratasysand Singaporian aircraft specialistSIA Engineering Company（siaec），received AS9100D Certification对于3D打印的航空航天零件。Stratasys的3雷电竞app下载D打印机也已由该领域的其他公司（包括英国的全球工程公司）利用GKN航空航天到reduce its production times，与航空航天专家一起IDECand prototyping service providerWehl＆Partner, who used a Stratasys 3D printer tocut the cost and material wasteinvolved with composite molding.
一月份，美国跨国航空巨头Boeing完成了第一次飞行的777 x飞机,powered by twin GE9X engines fromGE添加剂配备了超过300 3D打印零件. The new set of airplanes is expected to enter service in 2021.
空中客车本身对3D打印并不陌生，此前曾与Stratasys和Farsoon Technologies合作，making 3D printed plastics for civil aviation. Earlier this year, Airbus initiated a large-scale manufacturing project with researchers from theUniversity of Sheffield’sAdvanced Manufacturing Research Centre(AMRC). The researchers usedformlabs’3D printing technology to生产500个钻孔in two days, cutting the conventional lead time down by weeks.

3D printing the A320ceo wingtip fences
Satair’s A320ceo wingtip fences are installed in four different versions; starboard, port, upper, and lower, with these four parts referred to as a shipset. The printing of the wingtips took place at the Reference Manufacturing Shop in Airbus Filton, which was process qualified last year, with the build job for one shipset taking 26 hours.
After printing, the parts require various post-processing steps to become airworthy, and are supplied with EASA Form 1 certification approval. The first shipset was delivered to the airline earlier this year, making it the first operator with an Airbus metal 3D printed spare part.
与该零件的常规制造过程相比，非经常性成本降低了45％，使其对客户提供了更具成本效益的解决方案，并且交货时间大大缩短了。这款量身定制的3D打印解决方案还减少了该特定飞机的AOG（地面飞机）的可能性。
“Satair is leading the way in providing additive manufactured parts for the aviation aftermarket and we currently have more than 300 part numbers certified for the technology covering every Airbus aircraft famil type including tools and Ground Support Equipment,” said Bart Jeijnen, CEO of Satair. “With more than 7,000 A320ceo Family aircraft in service worldwide, the demand for this specific additive manufactured part is likely to increase and with this Additive Manufacturing supply chain now in place, we will be able to produce these parts within a shorter lead time.
“成功交付后，又有四个客户已经要求同一部分。”
Reijnen added that Satair had identified other titanium parts for which 3D printing could become a “more economical” way of production, citing higher flexibility and shorter lead times.
