China3D printingNet July 3, Wisconsin technology developer ADDere demonstrated its large-scale additive manufacturing capabilities by producing 5-foot-11-inch stainless steel turbine blades.leafThe film is produced during a 30-hour operation, and its error is within 0.5mm of its design thickness, which is an outstanding achievement of this technology.
Although the complex shapes were completed in record time, I think this part is spectacular, commented Scott Woida, President of ADDere.
ADDere is the additive manufacturing division of Wisconsin manufacturing company Midwest Engineered Systems Inc. (MWES).Its Directed Energy Deposition (DED) system was developed by MWES in 2017. As of February 2019, the company has used it as a metal3D printingService provision. High-strength alloys, including carbon steel, titanium, duplex stainless steel and super alloy Inconel, can all be processed by this technology.
As a system combination, ADDere currently has three machines (ADDere I, II and III), and the size of its structural components has increased from 40 x 40 x 20 inches (length x width x height) to 1575 x 310 x 75 inches and 1575 x 310 x 75 inch.
Except for a height of 5 feet 11 inches (61.32 inches in total), the model blade produced by ADDere has a width of 20 inches. The interior is hollow, with 0.5 mm wide side walls, and the structure weighs 135 pounds.

Through closed-loop on-site monitoring of the process, strict tolerances of the blades can be achieved. ADDere WALS control software also handles heating, cooling and melt flow parameters to prevent internal pressure.
“This is a very complicated process,” explains Pete Gratschmayr, ADDere’s vice president of sales and marketing. “The ability to maintain precise dimensions during 30 hours of metal heating and cooling, expansion and contraction, proves that the development of the software and control system of the ADDere system is very professional.”
About large-scale additive manufacturing
Large-scale additive manufacturing in metals has received attention from various industrial sectors because it can help reduce service and product delivery time and improve the performance of different systems.
Wire + Arc Additive Manufacturing (WAAM) is another example of technology applied to make some of the industry’s largest components. This year, Cranfield University and the commercial spin-off WAAM3D won the annual aviation/automotive application, using WAAM to produce a 2.5m x 1.5m rear frame for the BAE system Eurofighter Typhoon. WAAM is also the metal of choice in the maritime industry3D printingTechnology and applied to the production of 36,000 kg crane hooks of the famous WAAMpeller and Huisman.
The electron beam additive manufacturing (EBAM) of Chicago company Sciaky is another competitor for large-scale applications. Airbus has been studying the potential of Sciaky’s EBAM technology for many years, and the company recently confirmed that it will be part of a 4.2 million euro aerospace project led by IRT Saint-Exupéry in France.
Using DED Gratschmayr’s summary comment on the ADDere project added: “We are pleased to accept a large number of challenges to further prove the system.”
