Reduction of Micro‐Motion at the Tapered Connection of Hip Endoprostheses with an Adapted Deep Rolling Process of CoCrMo Inner Tapers

Advanced Materials Interfaces, Volume 12, Issue 18, September 22, 2025.
The ball burnishing processes demonstrated a notable reduction of surface roughness, which in turn helps to reduce the formation of wear particles and is reflected in the significantly reduced wear rate. The torsional resistance in the range of micro‐motion (≈2 Nm) can be improved by implementing a ball burnishing process with augmented depth hardness.

Predictive Approaches for 3D‐Printing: Methods and Approaches for Polymeric Materials

WIREs Computational Molecular Science, Volume 15, Issue 5, September/October 2025.
3D printing shows great promise, but suffers from a restricted range of materials. We show how computational methods, from physics‐based to data‐driven methods, can streamline the development of new polymer materials. Developing integrated approaches offers future opportunities in autonomous discovery and design, harnessing 3D printing's full potential.
