 This study investigates the influence of layer thickness and raster angle on the mechanical properties of 3D printed polyether ketone peak, and finds that the optimal properties are achieved at a layer thickness of 300 micrometers and a raster angle of zero degrees. The results show that the average tensile strengths of peak parts are 108% higher than those for acrylonitrile butadiene styrene ABS, while compressive and bending strengths are also significantly improved. However, the modulus of elasticity for both materials is similar, indicating that peak has superior mechanical properties to ABS in 3D printing.
