3D printing has played an important role in many industries over the past year, such as medical, education, and aerospace. It would take a very long time to list all of the amazing news in aerospace 3D printing in 2018, which is why we’ve chosen our top 10 stories for you about 3D printing in the aerospace industry and put them all in a single article.
Sintavia Received Approval to 3D Print Production Parts for Honeywell Aerospace
Tier One metal 3D printer manufacturer Sintavia LLC, headquartered in Florida, announced in January that it is the first company to receive internal approval to 3D print flightworthy production parts, using a powder bed fusion process, for OEM Honeywell Aerospace. Sintavia’s exciting approval covers all of Honeywell’s programs.
Boeing and Oerlikon Developing Standard Processes
Boeing, the world’s largest aerospace company, signed a five-year collaboration agreement with Swiss technology and engineering group Oerlikon to develop standard processes and materials for metal 3D printing. Together, the two companies will use the data resulting from their agreement to support the creation of standard titanium 3D printing processes, in addition to the qualification of AM suppliers that will produce metallic components through a variety of different materials and machines. Their research will focus first on industrializing titanium powder bed fusion, as well as making sure that any parts made with the process will meet the necessary flight requirements of both the FAA and the Department of Defense.
FITNIK Launched Operations in Russia
In 2017, FIT AG, a German provider of rapid prototyping and additive design and manufacturing (ADM) services, began working with Russian research and engineering company NIK Ltd. to open up the country’s market for aerospace additive manufacturing. FIT and NIK started a new joint venture company, dubbed FITNIK, which combines the best of what both companies offer. In the winter of 2018, FITNIK finally launched its operations in the strategic location of Zhukovsky, which is an important aircraft R&D center.
New Polymer 3D Printing Standards for Aerospace Industry
The National Institute for Aviation Research (NIAR) at Wichita State University (WSU), which is the country’s largest university aviation R&D institution, announced that it would be helping to create new technical standard documents for polymer 3D printing in the aerospace industry, together with the Polymer Additive Manufacturing (AMS AM-P) Subcommittee of global engineering organization SAE International. These new technical standard documents are supporting the industry’s interest in qualifying 3D printed polymer parts, as well as providing quality assurance provisions and technical requirements for the material feedstock characterization and FDM process that will be used to 3D print high-quality aerospace parts with Stratasys ULTEM 9085 and ULTEM 1010.
Premium AEROTEC Acquired APWORKS
Metal 3D printing expert and Airbus subsidiary APWORKS announced in April that it had been acquired as a subsidiary by aerostructures supplier Premium AEROTEC. Premium AEROTEC will be the sole shareholder, with APWORKS maintaining its own market presence as an independent company. Combining the two companies gave clients access to 11 production units and a wide variety of materials.
Gefertec’s Wire-Feed 3D Printing Developed for Aerospace
Gefertec, which uses wire as the feedstock for its patented 3DMP technology, worked with the Bremer Institut für Angewandte Strahltechnik GmbH (BIAS) to qualify its wire-feed 3D printing method to produce large structural aerospace components. The research took place as part of collaborative project REGIS, which includes several different partners from the aerospace industry, other research institutions, and machine manufacturers. Germany’s Federal Ministry for Economic Affairs and Energy funded the project, which investigated the influence of shielding gas content and heat input on the mechanical properties of titanium and aluminium components.
Research Into Embedded QR Codes for Aerospace 3D Printing
It’s been predicted that by 2021, 75% of new commercial and military aircraft will contain 3D printed parts, so it’s vitally important to find a way to ensure that 3D printed components are genuine, and not counterfeit. A group of researchers from the NYU Tandon School of Engineering came up with a way to protect part integrity by converting QR codes, bar codes, and other passive tags into 3D features that are hidden inside 3D printed objects. The researchers explained in a paper how they were able to embed the codes in a way that they would neither compromise the integrity of the 3D printed object or be obvious to any counterfeiters attempting to reverse engineer the part.
Lockheed Martin Received Contract for Developing Aerospace 3D Printing
Aerospace company Lockheed Martin, the world’s largest defense contractor, was granted a $5.8 million contract with the Office of Naval Research to help further develop 3D printing for the aerospace industry. Together, the two will investigate the use of artificial intelligence in training robots to independently oversee the 3D printing of complex aerospace components.
BeAM And PFW Aerospace Qualified 3D Printed Aerospace Component
BeAM, well-known for its Directed Energy Deposition (DED) technology, announced a new partnership with German company PFW Aerospace, which supplies systems and components for all civilian Airbus models and the Boeing 737 Dreamliner. Together, the two worked to qualify a 3D printed aerospace component, made out of the Ti6Al4V alloy, for a large civil passenger aircraft, in addition to industrializing BeAM’s DED process to manufacture series components and testing the applicability of the method to machined titanium components and complex welding designs.
Researchers Qualified 3D Printed Aerospace Brackets
Speaking of parts qualification, a team of researchers completed a feasibility study of the Thermoelastic Stress Analysis (TSA) on a titanium alloy space bracket made with Electron Beam Melting (EBM) 3D printing, in order to ensure that its mechanical behavior and other qualities were acceptable. The researchers developed a methodology, which was implemented on a titanium based-alloy satellite bracket.
