Context of Deposit
3D printing, also known as additive manufacturing, is a manufacturing process which puts down layers of materials to create a three-dimensional object. 3D printers take information from digital files about where and how to deposit the materials. Based on this data, the technology brings new objects to life, using a wide variety of different plastics and metals. Within hours, the machines can produce more complex parts than can be made with more traditional manufacturing processes—and at a much lower cost.
