3D Printing is a process of creating three-dimensional objects by adding material layer by layer, directly from a digital 3D model (usually a CAD file). It is one type of Additive Manufacturing, commonly used for prototyping, hobbyist projects, and small-scale production. 🏭 What is Additive Manufacturing (AM)? Additive Manufacturing is the broader industrial term for all technologies that build parts layer by layer using digital 3D design data. It includes 3D printing but also refers to advanced, high-precision, and industrial-scale techniques used in aerospace, automotive, medical, and tooling industries.
