Ceramic X.0

High-precision micro-manufacturing of ceramics

Engineered ceramic materials are widespread in various industrial applications due to their unique properties. However, it is difficult if not impossible to produce micron-scale high-precision ceramic components with current manufacturing techniques. The main aim of this project is thus to develop novel micro-manufacturing techniques for high-precision, ceramic components based on polymer-derived ceramics (PDC).

Scope of Research Activities
1. Development of polymer-derived ceramics (PDC) materials suitable for micro-casting
2. Development of processes and devices to ...

Manufacture micro-molds,
Fill preceramic polymers (PCPs) into these micro-molds (micro-casting) and
Transform the material into PDC micro-parts by pyrolysis

3. Characterization of the ceramic micro-parts regarding in vitro biocompatibility as …

Pacemaker electrodes
Dental implants

Key Technical Problems to Solve

Increase the achievable precision of the ceramic micro-parts.
Find ways to overcome current issues in the manufacturing of high precision ceramics due to shrinkage.
Define PDC compositions leading to bright colored implant materials.
Develop a suitable 3D in vitro model and setup with electrical pacing capabilities to study the fibrotic encapsulation of PDC implant materials.
