Printing a Functional Jet Engine

Posted June 19, 2015 12:00 AM by Engineering360 eNewsletter

Toy makers make toys. General Electric makes turbines. So it's not surprising that GE's latest proof of concept is a 33,000 RPM miniature jet engine created using direct metal laser melting. According to CNet, the foot-long engine is based on a design used for radio-controlled airplanes and actually works.

I don't understand DMLM ?

You mean 1 guy makes a drawing, then he engineers it, then he programs the computer, then he puts it together.

So, what do all of the other 99 people at the factory do ?

File for unemployment ?

Same as now. If you've watched "How It's Made", machines do all the skilled work. The human takes the piece off this machine and puts it on that machine, and maybe polishes it up to make it look nice at the end.

It's the same as any other company. They are all in management making sure the one guy doing his job understands how unimportant he is and how easy he is to replace.

The 3D prints for now, used for demonstration, so the client can have something to hold in there hand.

A friend that work at a company that designs and producing compressors use this for the compressor blades.

3D printing does have a ways to go yet.

But they are finding their niche, printing medical and dental devices as well as prosthetics.

Last year their stock was pretty strong, but 3 and 4 quarters of 2014 their stock fell about 50%-80%. In my opinion, they were over valued. But right now, I believe they are a little undervalued now. and should kick up a bit.
