Direct Digital Manufacturing Part One: What is Direct Digital Manufacturing

After 20 years, the future has become a reality. Additive fabrications technologies, which until recently have been relegated to rapid prototyping applications, have entered into the manufacturing realm. The use of additive fabrication processes is what differentiates direct digital manufacturing (DDM) from conventional manufacturing methods, and it is from these technologies that unique advantages and opportunities arise. Direct from 3D digital data, a component is manufactured—layer-by-layer—without machining, molding or casting.
