3D Printing PEM

This project covers the technological development of a PEM printer (Paste Extrusion Modeling).

Our company acted as the central source of ideas, initiator and driving force behind the entire solution. Through targeted technological optimisation and engineering innovation, the polyurethane multi-component process was lifted to a new level of performance and efficiency.

The system is designed specifically for large-format additive manufacturing. The printer uses two-component polyurethane binders and processes a range of granulates with grain sizes of up to 2.0 mm. Depending on the mixing ratio and material, parts can be printed to cure either elastic or rigid.

What we doView services

SmartProduct Development

We conceive and develop novel cyber-physical systems and interactive platforms. From the first idea to market readiness, we combine hardware, sensors and software into intuitive solutions that create real value in industrial settings.

Process &Value Stream Innovation

Innovation is not confined to the end product. We examine your process management and optimise the value stream. Using intelligent, modern methods, we unlock efficiency reserves across your entire value chain.

SystematicProblem Solving

We analyse highly complex tasks precisely and, through agile prototyping and structured design, turn them into focused, working and innovative solutions.
