Introduction to Additive Technologies
The term “additive fabrication” covers a wide range of technologies. They all rely on digital data to come with physical 3D models of objects. All of these technologies have a thing in common; they utilize layering of materials to come up with a final object. In most cases, the more layers that are used, the more an accurate representation of the data is made. These technologies are different from traditional manufacturing methods such as turning and milling. These methods rely on subtraction of material to come up with a final object.
