Cells are very sensitive to their direct environment - they place high demands, for example, on ambient culture medium, adjacent cell types, and the properties of surrounding material parts. As a result, mechanical and ...
Density-Based Topology Optimization for a Defined External State of Stress in Individualized Endoprosthesis

Müller, P.; Gembarski, P.C.; Lachmayer, R. (Cambridge : Cambridge University Press, 2022)

Endoprosthesis are exposed to the risk of aseptic loosening. The design of the prosthesis shaft to achieve physiological force application is therefore of great importance. Additive manufacturing offers the potential to ...
Design Rules for Laser Beam Melted Particle Dampers

Ehlers, T.; Lachmayer, R. (Cambridge : Cambridge University Press, 2022)

By means of additive manufacturing, especially laser powder bed fusion, particle dampers can be integrated locally into structural components and thus significantly reduce component vibrations. However, detailed design ...
Designing a methodological framework for the individualization of prosthetic implants: a literature-based approach

Müller, Patrik (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023-09-20)

Despite the considerable advantages associated with product individualization, the utilization of standardized components prevails in medical devices like prosthetic implants. This is primarily due to the laborious and ...
