However, fabricating complex 3D composites has historically presented challenges due to their structural complexity. This study presents the Additive Preform Molding (APM) strategy, a novel hybrid manufacturing method that integrates additive manufacturing with overmolding to produce high-performance composite structures. APM optimizes the alignment of continuous fibers based on load requirements and enhances structural integrity, starting with the creation of semi-cured preforms. These preforms are precisely shaped into specific configurations and subsequently overmolded with an infusion of short fiber-reinforced epoxy, thus enhancing their mechanical properties and facilitating the design of intricate geometries. The versatility of APM is represented through fabrication of various bracket designs. Mechanical testing reveals a tensile strength of 1109.3 MPa, a tensile modulus of 103.5 GPa, a flexural strength of 854.7 MPa and a flexural modulus of 96.6 GPa, confirming its substantial load-bearing capabilities for high-performance applications.
