Reinforcement Layers Built with Multi-Degree-Of-Freedom Material Extrusion Additive Manufacturing Achieve Strength Enhancement

To improve weak interlayer bonding in material extrusion, we propose a six-axis printing strategy with designed core and reinforcement layers. Mechanical tests and SEM analysis confirm that adjusting layer ratio, raster angle, and fill rate significantly enhances strength.
