Additive Manufacturing/ 3D Printing Using Composites
Additive manufacturing, commonly known as 3D printing, has revolutionized composite production by enabling the layer-by-layer construction of intricate composite structures. In the realm of composites, additive manufacturing techniques allow for the creation of complex geometries with precise fiber orientations and resin distribution, optimizing material performance. This technology offers the flexibility to customize parts, reduce waste, and experiment with novel composite combinations. By depositing materials layer upon layer, additive manufacturing facilitates the production of lightweight, high-strength components tailored for specific applications in industries such as aerospace, automotive, and healthcare, pushing the boundaries of what's achievable in composite design and fabrication.
