Enhancing the Mechanical Performance of 3D-Printed PEEK through Fused Filament Fabrication and Bioactivation Techniques

Introduction:

Additive manufacturing (AM) has revolutionized the production of physical models, enabling early fit and functional testing. AM techniques, also known as three-dimensional (3D) printing, involve adding material layer-by-layer to create complex structures. Polyetheretherketone (PEEK), a high-performance thermoplastic, has gained popularity in medical device manufacturing due to its biocompatibility and mechanical properties.

The Importance of Mechanical Performance:

However, the mechanical performance of 3D-printed PEEK depends on processing parameters, which can hinder its potential for custom-made implantable devices. The development of adequate approaches towards fused filament fabrication (FFF) parametrization is crucial in enhancing the mechanical properties of PEEK.

Bioactivation Techniques:

In addition to optimizing FFF parametrization, bioactivation techniques can improve the bioperformance of 3D-printed PEEK. Bioactivation involves using various methods to enhance the osseointegration of PEEK implants by promoting bone opposition.

Literature Review:

A review of available literature reveals that improvements in mechanical performance can be achieved through adequate FFF parametrization. Furthermore, different bioactivation techniques can be used to improve the bioperformance of 3D-printed PEEK.

In conclusion, this review highlights the importance of improving the mechanical performance and biocompatibility of 3D-printed PEEK for its potential in custom-made medical device manufacturing. The development of adequate approaches towards FFF parametrization and bioactivation techniques is crucial in enhancing the properties of PEEK. Further research is needed to fully understand the optimal processing parameters and bioactivation methods required to achieve improved mechanical performance and bioperformance.
