- PEEK is of significant interest to the aerospace industry due to its excellent thermomechanical properties but is difficult to 3D print due to its high viscosity which leads to poor layer-to-layer bonding and z-direction properties. Here we describe a novel approach to significantly improve printability of PEEK by exploiting the lubricating properties of IF-WS nanoparticles. Bombardier, partners on this EPSRC funded project (EP/N034783/1), wished to replace a machined metal bushing with a 3D printed part. We demonstrated that IF-WS2 improved PEEK printability, significantly reduced wear and increased impact performance paving the way for printing the bushing and other high-performance components.
