China3D printing Net October 17th,More in deployment3D printingOf all the possible industries of aircraft, aerospace may be the most exciting.By reducing the weight of aircraft components, increasing the number of iterations, integrating components and reducing the number of parts, andmanufactureOther craftsCan’t makeComponents, 3D printing can have a real impact on aerospace.From rocket technology to civil aviation. Stratasys has a long history of manufacturing polymer aerospace components that are mainly used in military applications.We interviewed Scott Sevcik, vice president of the aviation business unit of Stratasys, and learned about aviation3D printingTechnology development. Sevcik is an aeronautical engineer who has worked for Lockheed for eight years and held various engineering, project management and business positions.Then worked in UTC Aerospace Company, managing 100 peopleTeam of engineers. Finally, he held a key position in Stratasys,Manage their aerospace business.
Sevcik’s expertise in polymers and metals used in aviation and aerospace3D printingThe prospects for components are full of enthusiasm.Now although he has becomeStratasys military customers behind the scenesWorkers, but stillI really like the days of working with Boom to develop a supersonic airliner.. Sevcik said that now compared toThe initial use of the Fortus system for simple tool processing has improved a lot.They are building their own factories and in order to speed up, they are beginning to deploy more widely3D printing. “
Starting from the initial tools, fixtures and fixtures were added to the project just like the work on certain parts of the Boom simulator aircraft.Now they are considering adding3D printingThe parts are placed on the actual model, and then placed on the Boom aircraft.On the test aircraft alone, there are more than 100 potential3D printingApplications, especially after the Boom team fully understands the technology.
Sevcik insists that “the maturity of additives is sufficient to meet the needs of aircraft prototypes, tools and certain parts on the aircraft, but many customers “see the risks of additives as an unproven technology. “Now, the industry is entering a different state.Especially for certain applications, the combination of Ultem 9085 and Fortus 900mc system used in aircraft has a high degree of maturity.
As an example of such parts,SevcikEnumerate “luggage box, bulkhead, panel”. The company also provided examples of parts flying on business jets, including mass-produced parts. Commuter aircraft parts, speaker enclosures and many other applications.
“About 15 years ago, Stratasys first ventured into the aerospace industry and then entered the cabin.Sevcik knows very little about Stratasys’ defense business lines. As we all know, the company has a strong defense foundation with Lockheed, NASA and other companies.The University of Dayton Research Institute (UDRI) has proven the repeatability of 900mc in military aviation.
andSevcikAnother thing to talk about is its Antero PEKK material. Sevcik said, “Because PEEK crystallizes so quickly,” it is particularly useful in the aerospace industry, but “through Antero, you can better control the crystallinity” to “manufacture large PEKK parts.” Antero is “best for outside the cabin Applications. “
In addition to machine sales, Stratasys has also entered the aviation market through its Stratasys Direct Service business and the AS 9100 certified Harvest division. Many OEMs have “15% in-house manufacturing processes, and the rest are outsourced to partners.” In this case, OEMs need multiple partners. This means that in some cases Stratasys will work with partners and compete with them on certain technologies. Stratays hopes to “support OEMs and help their partners and customers start production” in this way, so as to “meet the needs of OEMs and customers.”
