| Abstract Scope |
Polyetherimide (PEI) is an amorphous high-performance thermoplastic polymer with high thermal stability, excellent comprehensive properties, and biocompatibility. PEI parts can be sterilized using a variety of procedures because they can withstand temperatures higher than 200 °C. As a result, PEI is commonly used for patient-specific instruments (such as surgical jigs). By incorporating additives into the PEI matrix, it is possible to enhance the mechanical and osteointegration capabilities, which are required for implants and medical devices. Here we present our comprehensive investigation of the printability, mechanical properties, and biocompatibility of fuse deposition modeling (FDM) of novel composite based on PEI containing carbon fibers and hydroxyapatite, and their potential to serve as bone reconstruction patient-specific implants. This investigation includes the optimization of the printing parameters, the study of anisotropic mechanical properties, and in vitro testing of the interaction between the surface area of the printed parts and human osteoblasts (bone cells). |
