Aeronaut Components makes a small aluminium bracket for a light aircraft. Each bracket is CNC machined from a solid aluminium block on the milling machine shown in Figure 3, with a rotating cutter removing material until the finished shape remains. The company makes the brackets in low volume and to a tight tolerance. A designer suggests that the brackets could instead be made by additive manufacturing, building each one up layer by layer from a 3D CAD model.
