Milan von dem Bussche - CFO and developer at QiTech Industries

Milan von dem Bussche

CEO & Finances
Finance & Development

Milan von dem Bussche

Milan has an overview of our projects (at least he pretends to). Developing new machines while doing something for the environment excites him.

At QiTech Industries, Milan designs and develops our machines and manages the finances (at least he does his best).
Luca-Tim ist bei QiTech unser Mann fürs Grobe – aber auch fürs Präzise. Ob Maschinenwartung oder Filamentproduktion: Luca hat für alles einen Plan – und wenn nicht, findet er einen. Sein Motto? „Das ist kein Problem, das ist ein Projekt.“

Luca-Tim Lauer

Operations Manager
Filament & machine production

Luca-Tim Lauer

Luca-Tim is our man for the rough stuff at QiTech - but also for the precise. Whether it's machine maintenance or filament production: Luca has a plan for everything - and if he doesn't, he finds one.

His motto? "It's not a problem, it's a project."
After working on his "Netucation" project, Paul is now back as a QiTech, turning our ideas into prototypes in record time. But anyone who only sees him as a brilliant inventor only knows half the truth. As our shopping adventurer, he knows better than anyone else in the team how to turn his gut feeling into spontaneous and sometimes expensive purchases that surprise us time and again.

Kim Louis Rübsamen is the head of our mechanical engineering production - and officially the man with the plan. Even if it sometimes seems as if the plan is only just being drawn up, Kim always delivers. While we are still discussing the best way to build something, he has long since planned it - and probably already produced it.

Konstantin Diegmüller

Where others see a challenge, Konstantin sees an opportunity for innovation. As the brains behind our special developments, he is already thinking about tomorrow's solutions today.

His current passion project is our new filament buffer.
His motto? "Talking is good, doing is better."

Christoph Eisenach

Marketing
Webdesign, SEO & Marketing

Christoph Eisenach

Christoph is our code alchemist. If his code doesn't work, he doesn't sleep, so basically he never sleeps.
But when his code does work, it's absolute magic.

Today, Chris is primarily responsible for the website of QiTech Industries.
Maxi Poser - Member of the production team of QiTech Industries

Alexandra Becker

Marketing
Social Media Management

Alexandra Becker

Alex and social media? It's like QiTech and innovative machines - inseparable.
In her free time, she doesn't just scroll through her Insta feed, she does research! - At least that's what she claims.

At QiTech , she lovingly takes care of our feed and always keeps track of everything between memes and marketing.

Noel Lieder

Marketing
Design & Branding

Noel Lieder

Noel creates, designs, rethinks and rebrands the graphics and brand of QiTech Industries. As an absolute deadline junkie, Noel has a talent to be hyper-efficient at night.

Apart from creating renders, mockups and animations, he is an passionate meme artist.

Tomoko Wiehler

Filament team
Filament production & material tests

Tomoko Wiehler

Tomoko is QiTech's self-proclaimed filament whisperer and regularly helps out with production.

She also pulls the strings in our material tests - almost as skillfully as our machines pull the filament.
Tomoko ist QiTech's selbsternannte Filamentflüsterin und hilft regelmäßig bei der Produktion aus. Nebenbei zieht sie aber auch bei unseren Materialtests die Fäden - fast so geschickt wie unsere Maschinen das Filament.
Maxi Poser - Member of the production team of QiTech Industries

Johannes Wetterling

Filament team
Filament production & process optimization

Johannes Wetterling

Johannes joined QiTech in 2019 as our first employee after spontaneously selling hundreds of key rings at a school festival.

Since then, Johannes has been managing our offices, running production and helping to develop new recycling processes.
Maxi Poser - Member of the production team of QiTech Industries

Maxime Donitza

Filament team
Filament production & process optimization

Maxime Donitza

During his school internship, Maxime quickly proved that he has a real talent for CAD and 3D printing.

Since then, it's hard to imagine QiTech without him - even if we sometimes wonder whether he likes our 3D printers a little bit more than us.

Edwin Massini

Head of Logistics
Deliveries & Warehouse

Edwin Massini

Edwin is QiTech's multi-talent: as a CAD designer, he used to turn our crazy ideas into precise 3D models. But because that got too boring for him, he now supports us with the logistics of QiTech Industries

When he's not busy in the warehouse, he probably sends parcels faster than the post office allows.
Kim Louis Rübsamen is the head of our mechanical engineering production - and officially the man with the plan. Even if it sometimes seems as if the plan is only just being drawn up, Kim always delivers.

Robin Krämer

Software
Programmierung der Control-Software

Robin Krämer

Where others only see lines, Robin sees the soul of the machine. He is the programmer of our control software and breathes life into our hardware with RUST.

He is driven by a fascination for code... or maybe just a lot of energy drinks?
