Additive manufacturing uses data computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, in precise geometric shapes. As its name implies, additive manufacturing adds material to create an object. By contrast, when you create an object by traditional means, it is often necessary to remove material through milling, machining, carving, shaping or other means.
Additive vs. Subtractive Manufacturing
3D Printing is also called additive manufacturing. Additive Manufacturing is when a raw material is placed, over time, one layer at a time, to build up a three-dimensional object.
Subtractive Manufacturing is where material is cut away from a solid material until the object that is desired is created. Wood carving is an example of subtractive manufacturing.
FDM 3D-Printer Assembly: (Ender Version 3)
In teams of three we assembled 3D-Printers in class. Through this we learned more about the makeup of the machines and the beginning processes like calibration and filament loading.
