Video: Metal Additive Manufacturing, Step by Step
A video from Pratt & Whitney illustrates the steps needed to additively manufacture an aerospace component.
Aerospace manufacturer Pratt & Whitney has been using additive manufacturing for prototyping since the 1980s, but just recently began producing service parts using a metal powder-bed process. The components the company is building will be part of the PurePower geared turbofan PW1500G engine, to be used in Bombardier aircraft.
The video above illustrates the production process for one such component. Beyond the significance of the engine, the video is worthwhile for its succinct depiction of the steps involved in additively manufacturing a metal component, both before and after the actual build. Fast-forward to the 1:20 mark to catch this step-by-step footage.
Is additive manufacturing (AM) ready for production scale? The latest issue of Additive Manufacturing magazine highlights manufacturers who are succeeding with 3D printing for production right now.
Machining a large 3D-printed part for aerospace composite tooling is fundamentally different than manufacturing the part traditionally. Baker Industries knows this first-hand.
An engineering modification that would have been impractical or cost-prohibitive in the past is realized on a machine tool performing metal 3D printing and machining in the same cycle.
