Video: Step by Step AM for Aerospace
The above video from aerospace manufacturer Pratt & Whitney illustrates the additive manufacturing of a component for the PurePower geared turbofan PW1500G engine. Aside from the significance of this engine for the aerospace industry, the video is also valuable for its succinct depiction of the steps in the metal AM process. Fast-forward to the 1:20 mark to catch this step-by-step footage.
What makes a good metal powder for additive manufacturing? Case study data highlights the value of particle size and shape, powder flowability, and bulk density.
Bringing safety to the forefront helps to mitigate the risk of additive technology within a manufacturing environment.
GE Additive’s Ehteshami says, “To make these parts the ordinary way, you typically need 10 to 15 suppliers, you have tolerances, you have nuts, bolts, welds and braces.” With additive, “all of that went away.” The helicopter project is a detail in a story worth knowing.
