威斯康星州技术开发商ADDere通过生产5英尺11英寸不锈钢涡轮机刀片的生产，展示了其大规模的添加剂制造能力。刀片的高度在一次30小时的运行过程中生产，可在其设计高度的0.5mm内保持公差，这是该技术的出色成就。
“While the complex shape was made in record time, the part is pretty spectacular in my opinion,” commented Scott Woida, ADDere President.
“The real story is being able to build such a large part on our system and stay so close to tolerances throughout the build is the most exciting aspect for us.”
保持> 0.5mm的公差
ADDere is the additive manufacturing division of Wisconsin-based manufacturing companyMidwest Engineered Systems Inc.（MWES）。它的定向能源沉积系统（DED）系统由MWES于2017年开发，截至2019年2月，该公司已将其作为一个金属3D打印服务。高强度合金，包括碳钢，钛，双链不锈钢和超合金inconel，这是该技术的处理。
As a system portfolio, ADDere currently has three machines (ADDere I, II & III) increasing in build part size from 40 x 40 x 20in (L x W x H) to 1575 x 310 x 75in and 1575 x 310 x 75in.
除了其高度为5英尺11英寸（总共61.32）外，Addere测量20的示范刀片宽。内部空心为0.5mm宽的侧壁，结构重135磅。
通过对工艺的原位监视，实现了刀片的紧密公差。ADDERE WALS控制SOFWARE还处理加热，冷却和融化参数，以防止内部应力。
“It’s a very complex process,” explains Pete Gratschmayr, VP of Sales & Marketing at ADDere. “Being able to hold dimension across 30 hours of metal heating and cooling, expansion and contraction, is a testament to how much knowledge has gone into the development of the software and control systems of the ADDere systems.”
Large scale additive manufacturing
金属中的大规模添加剂制造对各种工业领域都很感兴趣，因为它可以帮助减少服务和产品交货时间，并提高不同系统的性能。
Wire + arc additive manufacturing (WAAM) is another example of a technology being applied to make some of the industry’s biggest parts. This year, Cranfield University and commercial spinout WAAM3D won年度航空航天/汽车申请使用WAAM产生2.5m x 1.5 mBAE系统欧洲台风的后部框架。WAAM is also the preferred metal 3D printing technology of the maritime industry, and applied to the production of the famedWAAMpeller, and Huisman’s36,000公斤起重机钩。
来自芝加哥公司的电子束添加剂制造（EBAM）Sciaky是大规模应用程序的另一个竞争对手。空中客车一直在调查Sciaky的Ebam技术for several years, and the company recently confirmed that it would be part of a€420万欧元航空航天项目由...领着Irt Saint-Exupéry在法国。
使用DED Gratschmayr对Addere项目的评论总结说：“我们很高兴面对大型挑战以进一步证明该系统。”
