Further Development of the Design Process for Hybrid Individual Implants

Abstract

Additive manufacturing (AF) is characterised by a high degree of individuality and flexibility with regard to design and product layout. This enables the integration of different functions in a component. Due to these properties, AM has established itself in medical technology for the production of implants. Depending on the application, parameters such as resilience, biocompatibility and manufacturing restrictions play a varying role. So far, however, only limited research has been done on the design, manufacturing and application of hybrid implants (use of several materials). Although initial design and manufacturing guides exist, the problem of removing the hybrid implant from the shaping negative is hardly addressed.The aim is to analyse and evaluate an existing procedure for the design of hybrid implants depending on individual requirements and to further develop it regarding the removability from the shaping negative. In this context, the extent to which the adhesive properties between the elements can be influenced by design changes is to be investigated.

“…Furthermore, the design of large-area implants made of CPC is particularly difficult due to the fragile material behavior. Initial approaches to solving this problem demonstrate the realization of hybrid implant designs with a correspondingly load-bearing and bioactive material structure (Pendzik et al, 2023). Such a large defect therefore requires a load-bearing structure, which makes the implementation of a multiphase structure necessary.…”
