  Additive Manufacturing
“Components for prototypes and spare parts are better suited for SL processes, thanks to the benefits of free geometric design,” says Harald Eibisch, who works in Audi’s technology development department. “Also, the load capacity of components is comparable to parts made using traditional methods.”
Senvol Developing AM Software for Navy
Boeing and Oerlikon will use the data from this collaboration to support the qualification of AM suppliers to produce metallic components using a variety of machines and materials. The research will initially focus on industrializing titanium powder-bed-fusion AM and ensuring parts made with this process meet the flight requirements of the Federal Aviation Administration and Department of Defense.
Senvol, a New York City-based addi- tive-manufacturing (AM) services firm, has announced an effort to develop data- driven, machine-learning AM software for the U.S. Navy’s Office of Naval Research (ONR). Senvol software analyzes the rela- tionships between AM-process parameters and material performance. ONR’s goal, to have software assist in developing sta- tistically substantiated material properties, will reduce conventional material char- acterization and testing now needed to develop design allowables.
capabilities,” Wang continues, “we also have developed a computer-vision algo- rithm that analyzes, in real time, in-situ monitoring data. This enables us to detect irregularities and to begin quantifying the relationships between irregularities in the build and the resulting mechanical per- formance.”
“Our software capabilities will allow ONR to select the appropriate process parameters on a particular additive-man- ufacturing machine given a target mechan- ical performance,” says Annie Wang, pres- ident of Senvol. “This presents a unique opportunity to reduce the high level of trial and error currently required, which would save a tremendous amount of time
Boeing, the Chicago-based aerospace company, and Oerlikon, a technology and engineering group with headquarters in Pfäffikon, Schwyz, Switzerland, announced the signing of a five-year collaboration agreement to develop standard materials and processes for 3D metal printing.
The Bossard Group, the Switzerland- based provider of fastening solutions, engineering and consulting services, and smart-factory logistics solutions, has announced three partnerships that will gain it entry into 3D printing. The partners are Trumpf (laser metal fusion), German RepRap (fused filament fabrication) and Henkel (stereolithography). The partner- ships will allow Bossard to sell 3D industrial printers and related consumables (metal powder, filaments, etc.).

Bossard Group Enters 3D-Printing Market
“This agreement is an important step
toward fully unlocking the value of pow- der-bed-titanium additive manufacturing for the aerospace industry,” says Leo Christodoulou, Boeing’s chief technologist. “Boeing and Oerlikon will work together to standardize AM operations from powder management to finished product and thus enable the development of a wide range of safe, reliable and cost-effective structural titanium aerospace components.” Boeing currently has more than 50,000 3D- printed parts on commercial, space and defense products.
 Audi Commits to SLM Solutions’ AM Technology
“This program will drive the faster adoption of additive manufacturing in the rapidly growing aerospace, space and defense markets,” says Dr. Roland Fischer, CEO of the Oerlikon Group. “Work- ing together with Boeing will define the path in producing airworthy AM compo- nents for serial manufacturing. We see collaboration as a key enabler to unlocking the value that AM can bring to aircraft platforms and look forward to partnering with Boeing.”
Audi AG has announced that it is producing prototype parts and components on demand using SLM Solutions’ SLM 280 selective laser melting system. The machines create metal parts passed on 3D CAD data, including a water adapter for the Audi W12 engine.
“Manufacturing on demand is a vision for us to ensure an economical and sustainable supply of original spare parts, which are required less often,” says Dr. Alexander Schmid, after sales manager at Audi AG. “Regional printing centers would simplify logistics and warehousing.”
