Vision-Guided 3D Printing for Aircraft Blade Repair

One important application of metal additive manufacturing in the aerospace industry involves not making new parts, but repairing existing ones. Aircraft engine blades such as compressor and turbine blades are subject to wear. Historically these components have been repaired manually, through the work of a skilled welder, but 3D printing via directed energy deposition (DED), guided by optical measurement of the worn blade for generating custom program paths, offers the chance for an automated, unattended system to perform this repair operation. During a visit to Optomec's facility in Clover, South Carolina, I saw how additive manufacturing for aircraft engine blade repair works. This video shows DED of Inconel 625 applied in two different types of paths to repair the tips of a compressor blade and a turbine blade.

Amazing machine. I believe that's the trailing edge btw. 02:35

@AdditiveManufacturing Год назад

From Peter Zelinski: “You are right! The point about the needed strength of the material on the edge is still valid. But I said ‘leading edge’ when I was actually pointing at the blade’s trailing edge.”

Damn, that's so awesome

Yeah put "compessor" blade in title i was so confused thinking u where talking about the wings. Those blades must cost a fortune since u can afford such a revolutionary process

@shanegonzales Год назад

Think of the possibilities if DED and subtractive manufacturing processes for surface finish could be combined into one program at one machine.

is this a Direct Metal Laser Sintering (DMLS)??

@AdditiveManufacturing 3 месяца назад

No, the term DMLS refers to a powder-bed process. The process seen in this video is directed energy deposition, or DED. There is still metal powder as the raw material, but not in a bed. It is precisely deposited through a nozzle instead.

First

Yikes! "Shorter grains"? Turbine blades are single crystal casting, which gives them their extreme strength and thermal performance. Throw that broken blade into the scrap heap and melt it down and cast a new single crystal casting. I think this company has selected a business model that would be useful to Chinese manufacturers who have the reputation of inferior components because they cut corners and use simple physics where complex physics is essential.
