Who we are

We are diverse in the truest sense of the word. In every respect.


There were just five of us six years ago. We now number more than 100. And this figure is continuing to grow.


We are a unique mix of screen printing experts, engineers, assembly specialists, developers, programmers, mechanical engineers, material scientists, marketing wizards and financial experts who keep a close eye on the latter.

And we are all shareholders of our company. Of our Exentis. All of us. Without any exception. You will not find that anywhere else.

Our lawyers have told us not to write anything like this. It is possible that there is another company of a similar size with a comparable business model, in which all the employees have a stake, somewhere else in the world.

We do not believe that. But we believe in the uniqueness of Exentis and its technology, for the benefit of our customers.

That is why we have made this statement anyway.

Michael is our lead development engineer. Together with his team, he ensures that our 3D production systems deliver what our marketing wizards promise: high-quality production on a large scale.

He is also taking care of the ongoing development of our systems.
Our 3D screen printing experts are familiar with all the secrets of 3D screen printing.

And every day they are fascinated by the exciting possibilities that 3D screen printing technology offers. Just as we all are.
No component can be produced without some material, i.e. without a paste. Noémie and Latifa, our paste system experts, can turn almost any powder into a paste.

But it all comes down to having the right mixture. It is a science in itself. But not for Noémie and Latifa.
Gabriel is one of our project leaders. He supports our 3D community members – and all those who want to become one – from the initial application concept to its specific implementation.

With his Austrian charm and his reliable statements.
Christine heads the Legal & Compliance department. With her legal expertise and her maximum precision, she ensures that we do everything properly at our company. And she leaves nothing to chance.
Hector is one of our trainees. After spending a day to see how things operate, he immediately knew that he would like to launch his career at Exentis.

It is now hard to imagine the 3D screen printing team without him.
Carsten is responsible for our comprehensive patent portfolio, which forms the basis for granting exclusive long-term licenses to our customers. And he is further developing the portfolio on a continuous basis.
Uwe and his team handle the product management and configuration of our 3D systems, ensuring that our customers get exactly what they had in mind.
That is diversity in practice. Every day.
And that is what is moving us forward.

However, we are also absolutely united. We are determined to offer the users of our 3D technology platform, our 3D community members, unique value added.

And for the sake of completeness: Yes, we do have something like a Management Board and a Board of Directors. Some say unfortunately – others fortunately.
