“all in” at ACTech means: having all, mastering all, giving all, maintaining all. That’s why we have always relied on in-house solutions. All casting and CNC machining processes related to rapid prototyping are carried out in-house, right up to the ready-to-install part. Our “all in” concept is the basis for our practice of controlling all production processes ourselves and for our ability to realise extremely fast cycle times. This makes us more independent, more reliable and faster than others. Ultimately, it is this concept in combination with our experience from more than 25,000 different prototyping projects that convinces our customers to go “all in” with us time and again.

Rapidest Prototyping

Welcome to the front-runner. Since 1995, we have been continually setting new standards for rapid prototype production in terms of both quality and speed. Employing innovative methods and technologies partially developed in-house, in conjunction with complete in-house management of processes and perfectly organized workflows. The results are high-precision, finished ready-to-install casting prototypes, produced in record time. Our customers around the globe, especially in the automotive, engineering and aerospace sectors, place great value on our technological advances and reliability. Speed is one reason our customers keep going “all in” with us.

Our new trailer is ready!

25 years of ACTech! A perfect occasion to produce new ACTech film material. Today we proudly present our new ACTech trailer.
Now see for yourself what is behind ACTech and what "all in" means to us!






In these challenging times, taking action is the only way to be proactive.
We at ACTech are committed first and foremost to protect our employees - their health is our top priority.

We are at your side for this challenge! 


Expansion of capacity

In December we expanded our capacity with a new ExOne S-Max Pro phenolic resin printer. This expansion contributes significantly to our fast and qualitative "all in" concept. The assembly work has been completed and the printer can start production now.
