3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. Additive manufacturing (AM) or additive layer manufacturing is the industrial production name for 3D printing, a computer controlled process that creates three. Additive manufacturing (AM), also known as 3D printing, is a transformative approach to industrial production that enables the creation of lighter, stronger parts and systems. What is Additive Manufacturing? · Additive · Manufacturing ( · (AM) is an appropriate name to describe the technologies that build 3D objects by · adding layer-upon-. Additive manufacturing is the official industry standard term (ASTM F2792) for all applications of the technology. The basics in Additive Manufacturing is rather than taking material away, it adds to it instead.
