Graphene-Enhanced 3D Printing: Advancing Functional Additive Manufacturing
Additive manufacturing (AM), commonly known as 3D printing, has revolutionized prototyping and production in multiple sectors. However, traditional filaments and resins often lack the electrical, thermal, and mechanical performance required for advanced use cases. Enter graphene, whose extraordinary properties are transforming 3D printing materials from passive structures into functional, intelligent components.
