GE宣布它正在建造世界上最大的激光粉末床金属3D打印机。这台金属添加剂制造机目前称为“ Atlas”，其构建体积为1米立方体（1,000mm³）。
独家报道的3 d印刷行业April, Vice President and General Manager of GE Additive, Mohammad Ehteshami revealed the company was今年早些时。
The machine, currently a technology demonstrator, will overtake thecurrent leader Concept Laser’s XLine 2000Rwith a build envelope of 800 x 400 x 500 mm. GE去年获得的概念激光and has incorporated the German company’s laser expertise in developing the ATLAS.
由于该项目在过去两年中一直在开发中，in house expertise from GEwill also have been vital.
Aerospace application
公告是在the Paris Air Showand GE explains the machine is tailored for the aerospace industry. GE has already advanced the use of 3D printing in the aerospace industry使用Leap燃油喷嘴。
GE将在今年晚些时候在Formnext上更详细地揭幕Atlas项目。GE Addivity的Mohammad Ehteshami副总裁兼总经理解释了3D打印的潜力，用于航空航天应用程序的Atlas，
该机器将直径为一米的3D打印航空零件，适用于制造喷气发动机的结构组件和单式飞机的零件。该机器还适用于汽车，电力和石油和天然气行业的制造商。
According to GE, the ATLAS demonstrator machine is the result of two years of development with several prototype iterations. GE has recently publishedtwo patents relating to the acoustic monitoring of metal additive manufacturing machines。这些创新旨在提高金属3D印刷零件的可重复性和认证，并且可能已在这台新机器中实施。
Availability and release
GE reports it is hoping to deliver the first machines in late 2018. As Ehteshami says,
We have customers collaborating with us and they will receive beta versions of the machine by year’s end. The production version (yet to be named) will be available for purchase next year.
