FIT and EOS - Pioneers of Additive Manufacturing

April 20, 2021 | Reading time: 2 min

FIT was one of the first service bureaus to focus on rapid prototyping using 3D printing. Today the specialty supplier operates one of the largest additive manufacturing factories in Germany with 21 EOS systems.


Innovative companions for over 25 years

Carl Fruth first worked for EOS before founding FIT Additive Manufacturing Group in 1995, one of the first service bureaus to focus on rapid prototyping using the innovative technologies of 3D printing. Today, the company operates one of the largest additive manufacturing factories in Germany employing both polymer and metal systems from EOS.

Carl Fruth was the first applications engineer at EOS, and his ability to innovate played a key role in the company's success during its first phase of development. The engineering graduate began his career in 1992 at the then start-up EOS in Planegg near Munich. However, he always knew that he would become an entrepreneur.

In 1995, Fruth started with used stereolithography machines from EOS in his garage in rual Lupburg in Southern Germany. Two years later, he built his first manufacturing building nearby in Eichenbühl. Today, the FIT Additive Manufacturing Group employs 280 people and is a service provider for various components and end products. This is because Fruth does not rely solely on additive manufacturing but combines it with conventional processes such as injection molding and investment casting. For example, 3D printing is used to produce the tool and injection molding used to produce the component.


Our many years of cooperation have shown that EOS is a very reliable partner. With different applications, new challenges arise every day and we always receive great support from EOS.

FIT uses thirteen polymer and eight metal systems from EOS. The team runs seven EOS P 760, and in 2017, the company invested in four EOS M 400-4 systems. These are used primarily to manufacture products for the automotive, motorsports, medical and aerospace industries. “We see a particular strength of the EOS technology in the surface finish of the components”, emphasizes Fruth.

Just recently, in 2020, FIT added a system from AMCM's custom machine shop. "This system has a telecentric lens for particularly fine resolution, and we are currently analyzing this exciting technology as part of a research project," Fruth explains.

We have been supporting Med In Town in the development of a duplicatable Micro Factory that allows 3d printed medical devices to be manufactured in close proximity to medical care centers. Thanks to the great success of this initiative, the company is now in a position to expand internationally and diversify its field of activity.

Do We 3D Print or Additively Manufacture?

Since the beginnings of the industry we work in, the terminology relating to what we do has evolved in parallel the technology itself. As in many industries, the terminology was initially defined by the pioneering companies and innovators of the industry, then formed by users, media, and other influencers, before gradually being standardized.
