《经济学人》报导， 通用电气航空集团(GE Aviation)收购了一家员工数仅为130人的公司Morris Technologies，该公司投资研究了航空发动机零件的3D打印技术，使用3D打印机器和激光烧结工艺，Morris公司可以一层层建造出数字化描 述的零件。零件打印的一大优势是节省材料，使用金属钢坯锻造零件必须根据零件形状削掉大量材料。3D打印的另一个优势是可以制造出更轻的零件，帮助飞机节 省燃料。许多制造商早就开始使用3D打印制造零件原型，它比传统模具制造更廉价和更具有灵活性。现在，这项技术已经为正式生产做好了准备。通用合资公司 CFM国际的LEAP喷气引擎将使用部分Morris Technologies的打印零件。

CONFIRMATION as to how seriously some companies are taking additive manufacturing, popularly known as 3D printing, came on November 20th when GE Aviation, part of the world’s biggest manufacturing group, bought a privately owned company called Morris Technologies. This is a small precision-engineering firm employing 130 people in suburban Cincinnati, Ohio. Morris Technologies has invested heavily in 3D printing equipment and will be printing bits for a new range of jet engines.Morris Technologies uses a number of 3D printing machines, all of which work by using a digital description of an object to build it in physical form, layer by layer. Among the 3D printing technologies used by Morris Technologies is laser sintering. This involves spreading a thin layer of metallic powder onto a build platform and then fusing the material with a laser beam. The process is repeated until an object emerges. Laser sintering is capable of producing all kinds of metal parts, including components made from aerospace-grade titanium.
One of the attractions of printing parts is that it saves material. Instead of machining components from solid billets of metal, in which much of it may be cut away, only the material that is needed to shape the part is used. Printed parts can also be made lighter than forged parts, which promises fuel savings.
Many manufacturers already use 3D printing to make prototypes of parts, because it is cheaper and more flexible than tooling up to produce just one or two items. But the technology is now good enough for it to be used to make production items too.
Among the components that Morris Technologies plans to print will be some used in the LEAP jet engine (pictured), which is being developed by CFM International, a joint venture between GE Aviation and Snecma of France. The LEAP engine is scheduled to enter service in the next few years on a number of short-haul airliners. More than 4,000 engines have already been ordered.
GE is buying Morris Technologies (which includes a sister company, Rapid Quality Manufacturing) for an undisclosed sum. GE sees the purchase as an investment in an important new manufacturing technology. “Our ability to develop state of the art manufacturing processes for emerging materials and complex design geometry is critical to our future,” said Colleen Athans, general manager of GE Aviation’s supply-chain operations.
Some people think additive manufacturing will overturn many of the economics of production because it pays no heed to unit labour costs or traditional economies of scale. Designs can be quickly changed, so the technology enables flexible production and mass customisation.
The GE deal is further evidence for those who believe that product innovation will increasingly go hand-in-hand with manufacturing innovation. So proximity of production and R&D will matter more. With GE Aviation based just outside Cincinnati, the firms are almost neighbours.《经济学人》报导， 通用电气航空集团(GE Aviation)收购了一家员工数仅为130人的公司Morris Technologies，该公司投资研究了航空发动机零件的3D打印技术，使用3D打印机器和激光烧结工艺，Morris公司可以一层层建造出数字化描 述的零件。零件打印的一大优势是节省材料，使用金属钢坯锻造零件必须根据零件形状削掉大量材料。3D打印的另一个优势是可以制造出更轻的零件，帮助飞机节 省燃料。许多制造商早就开始使用3D打印制造零件原型，它比传统模具制造更廉价和更具有灵活性。现在，这项技术已经为正式生产做好了准备。通用合资公司 CFM国际的LEAP喷气引擎将使用部分Morris Technologies的打印零件。

零件用于LEAP喷气发动机”，而不是直接“打印喷气引擎”吧？
SLS/SLM工成型艺本来就不是啥子特别新的工艺了。 就和电化学加工一样，有着应用的局限性。
这个跟王教授的东西是不是一个概念的？
这个3d打印技术现在只能打印模型吧，它对不但原料的有特别的要求，而且现在3d打印只能做个外形，产品的内部晶体结构没有办法做。
听起来好像和把大象放冰箱里一样简单
激光烧结工艺，Morris公司可以一层层建造出数字化描 述的零件。
打印的技术还是不行吧
零件吧。发动机想打印？再等几十年吧
北航和西工大都已经有这玩意儿了
并非不可能 现在科技发展那么块
这个现在不行吧？
个人猜测
是用来做测试机 验证形状的性能
而不能用于商业批量
发动机的性能要求太高了

翠花 打印一台轿车
太大的工业作品不指望.....考虑先打点钞票花花...............
不知道打印对材料有何要求？
