The world of electron beam 3D printing is suddenly becoming larger. Whereas it was previously dominated by a single company, GE’s Arcam, there have been a number of new entrants as of late. One that has been

Germany’s pro-beam Group has partnered with 3D printing specialist FIT AG to develop additive manufacturing (AM) processes relying on electron beams. According to their recent framework agreement, they will “pool their know-how and create new technological opportunities through the resulting synergies.” This will include process, materials, and equipment for electron beam technology.

FIT AG is the German AM specialist that spun out Netfabb, one of the leading 3D printing software developers that was ultimately bought by Autodesk. With more than 25 years in the AM space, the company offers industrial 3D printing services and develops data preparation and 3D printing process technology.

pro-beam has been in the world of electron beams for over 45 years, specializing in welding, hardening, drilling and surface coating. More recently, the firm entered the AM space with both directed energy deposition (DED) and powder bed fusion (PBF) technologies.

“The respective expertise of the two companies FIT and pro-beam holds enormous potential,” says Dr. Thorsten Löwer, CTO at pro-beam, “to achieve a significant expansion of additive manufacturing applications using the electron beam.”

“I am convinced that this technology cooperation will produce important results,” explains Carl Fruth, founder and CEO of FIT AG, adding “We have some very specific ideas in mind that we can now tackle with pro-beam to achieve a market-ready technology solution.”

We’ve reached out to pro-beam to learn exactly what “very specific ideas” the company has in mind. Regardless, they are involved in a space that is currently becoming quite exciting. Companies like Wayland Additive and JEOL claim to address the existing issues faced by electron beam PBF, ensuring greater levels of repeatability and control. Meanwhile, there is Xi’an Sailong Metals in China and FreeMelt , the latter of which has an open architecture, making it more flexible for material and application development. All of these are operating under the shadow of GE Additive, which has the most established history and reputation in the space.

I am not aware of any other company offering electron beam-based DED, making pro-beam a first in the space. What advantages this technique has over other energy sources, such as plasma arcs, is hard to know and we’re hoping that pro-beam can enlighten us. This also makes pro-beam the only one electron beam 3D printer manufacturer tackling both DED and PBF, giving it the ability to produce both large and small parts and leverage the benefits of each. For DED, this might include the 3D printing of a much wider variety of materials, as well as the ability to combine them. PBF is valuable for highly detailed components with complex geometries. Collaborating with FIT AG will likely speed up any development the firm planned to do on its own, giving pro-beam access to an even broader understanding of the AM industry.
