GE Additive—the additive manufacturing (AM) business of American multinational conglomerate General Electric (GE)—has revealed the prototype of a metal binder jetting (BJ) machine that it expects to challenge the need for castings.
The prototype, referred to as H1, can be used to print large parts in a range of materials, including stainless steel, nickel and iron alloys. Its aim is to eliminate the need for castings and therefore expensive tooling and molds. The company claims that this initial version of its machine is faster than any BJ machine on the market.
Mohammad Ehteshami, vice president and general manager of GE Additive, commented: ‘We see great demand for binder jet technology in the aerospace and automotive sectors. We are committed to accelerating the additive manufacturing industry and will continue to build on our strength in the laser and EBM modalities by developing and bringing new technologies to market. We have a progressive approach to innovation and product development. I challenged the team to develop this new machine in 55 days. They came in ahead of time with the process of concept to first print taking only 47 days.’
Further iterations of the machine are to be made in early 2018 and the first production machines shipped in mid-2018.
