Research & Development

Between practice and theory, we have extensive experience, broad scientific expertise, and connections, as well as a selected, interdisciplinary team of specialists at our disposal. With them, we follow a structured path to gain new insights in various development processes. To implement this, we utilize a wide range of modern manufacturing and analytical methods.

Additive Manufacturing, commonly known as 3D printing, has revolutionized the production of complex geometries with various materials. One of our focal points lies in the development of additive manufacturing of bioabsorbable magnesium and zinc alloys. The unique challenges posed by factors such as the reactivity and flammability of magnesium have prompted us to seek innovative approaches for its successful integration into AM processes.

Additionally, we are engaged in post-processing of additively manufactured components. Methods for surface treatment are developed to meet the challenges and requirements of this technology area.

Plasma-elektrolytic Oxidation

Plasma Electrolytic Oxidation (PEO) is an advanced surface modification process that enhances the properties of metals and alloys. By applying an electric potential to a component immersed in an electrolyte solution, a plasma discharge triggers electrochemical reactions, leading to the formation of a ceramic-like oxide layer. This layer can be individually tailored to your application in terms of thickness, composition, and structure, resulting, for instance, in improved corrosion resistance, wear resistance, hardness, and other desirable properties. The unique microstructure of PEO, including nanopores and crystalline phases, further contributes to its effectiveness. The PEO technology employed by Meotec is applied in various fields: medical technology, aerospace, propulsion technology, renewable energy systems, and is subject to continuous research and innovation.

Electropolishing

Electrochemical etching is a controlled and precise surface modification technique, where material is selectively removed from a metal substrate through electrochemical reactions. In this process, the metal is immersed in an electrolyte solution, and a direct current (DC) or alternating current (AC) is applied. This causes metal ions to be dissolved from the surface, enabling effortless processing of complex geometries.

Our technology is applied across various industries, particularly in the manufacturing of medical implants, the automotive industry, and the aerospace sector. It is also utilized for post-processing of additively manufactured parts.

Both technologies are integral components of our Engineered Systems portfolio and are accommodated within our automated manufacturing facilities

Our in-house analytics encompass all metallographic, chemical, optical, and mechanical characterization capabilities necessary to fully and independently handle development processes. With a wide range of analytical equipment and the expertise of experienced staff, we can respond promptly to individual customer or project requirements.

The combination of versatile manufacturing processes, process chains for the production of medically suitable materials or entire implant systems, and in-house analytics makes us an outstanding partner in the field of contract research.

The foundation of our company is science. Without thorough knowledge and testing, no product can reach market readiness.

Our partnership with RWTH Aachen University and FH Aachen University is reflected in numerous R&D cooperation projects. We have published our current projects under ‘News’.
