Manufacturing of metal-polymer composites for medical applications

Abstract

Purpose: The purpose of the article is to present the design and fabrication methodology of metallic scaffolds, with the shape and dimensions defined by the designer, coated with a thin layer of polymer. Design/methodology/approach: The methodology proposed covers Computer Aided Materials Design (CAMD), fabrication of metallic scaffolds using a machine for Selective Laser Melting (SLM), the deposition of a thin layer of polymers onto scaffolds using coldwork and hot-work polymerisers, as well as mechanical finishing. The strength of the newly developed metal-polymer composites to three-point bending was examined and their fractures were viewed with SEM. Findings: A fabrication method of implants in the form of scaffolds coated with a thin layer of polymer with the dimensions and shape closely matching the losses in a patient’s hard and/or soft palate. Practical implications: After clinical tests, a metal-polymer implant may be a very beneficial alternative for patients with palate losses using traditional prostheses until now. Originality/value: The individualised implants of palate pieces in the form of scaffolds coated with a thin layer of polymer, submitted for patent protection, do not have their counterparts, which is representing their originality.
