3D printing, or additive manufacturing, is the construction of a three-dimensional object from a conceptual design visual format to a much realistic replica.
This technique is used for a lot more than what we could envision.
3D printing, also known as additive manufacturing, creates three-dimensional components from CAD models. It mimics the biological process, adding material layer by layer to create a physical part. With 3D printing, you can produce functional shapes, all while using less material than traditional manufacturing methods.Each of these layers can be seen as a thinly sliced cross-section of the object.
3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
The result of the wider availability of 3D printing is that a huge number of industries are beginning to feel the disruption. As the 3D printing workflow empowers both individuals and organizations to take control of their own design and manufacturing processes, more and more use cases are springing up.
