The 3D printing system EXT 220 MED manufactured by 3D Systems GmbH is used within the framework of DFG Project No. 554396778 for the additive manufacturing of polymer-based components using the fused layer modelling process.

In this process, a thermoplastic filament is melted in a heated nozzle and deposited layer by layer along predefined toolpaths onto a build platform, enabling the fabrication of three-dimensional structures directly from digital CAD models. The system is specifically designed for processing medical-grade high-performance polymers such as PEEK and allows the production of dimensionally accurate and mechanically resilient components through controlled process conditions and a heated build chamber.
