Definition and Brief History
Additive Manufacturing (AM), commonly referred to as 3D printing, is an advanced manufacturing process that builds objects layer by layer from digital models. Unlike traditional manufacturing techniques that involve cutting or subtracting material from a solid block, Additive manufacturing adds material incrementally, making it easy to achieve complex designs with minimal waste. This technology has revolutionized the way products are created, offering flexible design and customization.
According to research, the origin of additive manufacturing dates back to the 1980s when it was first developed for rapid prototyping, allowing engineers and designers to create and test product models quickly before mass production. The first 3D printer was introduced by Charles Hull in 1987, using a technique known as stereolithography. Over the years, the technology has evolved and expanded its applications beyond prototyping, becoming integral to industries like automotive, aerospace, medical, and consumer products. Today, AM enables the production of highly complex geometries, lightweight parts, and personalized items at a lower cost compared to traditional methods, making it a key innovation in modern manufacturing.
