Engine-ering porn

"Slick" doesn't come close my friend! AMAZING! :eek:

The video just blew me away. Truly engineering porn!

I am still just stunned at the 3D printing technology. It's like science fiction come true.

Thanks for the E-porn fix! :lol:

Part of that was filmed in my shop, I work right next to the guy with the large beard doing the borescope.

Some really awesome tech there

Cool, the 3D printing is what is going to allow us to build extremely large space habitats to move man off Earth. The smaller design trials can go to the asteroid belt and bring back the raw materials to build it with in orbit using 3D printing.

That just freaks me out! How cool is that! Seriously! :eek:

Like I keep saying, technologically there is nothing we can't achieve. The issue is always how we implement technology and dedicate resources.
 
I wonder if those planetary sets were a demo of what can be done in making "no assembly required" machines or if they are actual parts?

What is the stock symbol of that company?

And what "printers" do they use? What is the company name for them?

You have to buy the printer company stock through a French broker. However, GE will probably end up with it in the collapse of the Eurozone.
 
Makes sense, GE has been doing additive construction with Plasma Spray techniques for a long time. My buddy from back in the day who worked for them doing it in the 80s saved a compressor crank for me with it.
 
We've got a few 3D printers we use for development, but production items don't come out of them. We can use the items for testing, but would never sell them because they wouldn't hold up to the abuse. Works wonders for our development.

The process is called direct metal laser sintering. These guys make them, dunno if it's what GE is using.

The new GE LEAP and the Pratt & Whitney PW1000G engines both feature one piece titanium fan disks. I have no idea how they do it. Compare that to the 1970's inability of GE to cast just the hubs on the GE CF6 fan disk without the hard alpha inclusions which brought down United Flight 232 in Sioux City.

P&W has also stolen away Gulfstream's business from Rolls with their new PW800. It will be on the new Gulfstream 500 and 600 models.

Very cool.

Why didn't they show the bird ingestion test?

It almost seemed as if they were going too.
A clip of ducks flying as they are discussing the bird test.

I thought the ducks were about to get redirected into the blender for a brief moment.
 
That is very cool. I didn't know 3D printing of metal parts like that was possible.

Ok the secret is out....we've been 3d printing parts since the early
90's.....the only difference is that the materials have improved from plastics, to resins, to impregnated metals......

Is this an "impregnated metal" process, or is this basically laser welding on layer after layer? Those were fuel nozzles right? What impregnated materials exist that take that heat? If these are solid metal, heat resistant parts, that's a big deal.

I believe the sintering process produces a "green" part that requires further processing and heat treatment.

Sintering results in a solid metal form...the parts are the same as an assembled casting according to the video but formed in a manner impossible with discrete parts.

sin·ter
ˈsin(t)ər/Submit
verb
gerund or present participle: sintering
make (a powdered material) coalesce into a solid or porous mass by heating it (and usually also compressing it) without liquefaction.

That's what I took away from the video as well, these are a pure metal product, and light I would imagine as sintered metal products always are.
 
I can't find the link for it right now, but I read (actually skimmed due to lack of time) an article about a project to print human organs using 3D printers.

I believe that, but I hope it's not like the meat grown in a Petri dish.

I saw something like that come through my inbox.
 
ASU is working a capstone engineering project with Sandia Labs on using the technology for new applications, I am curious to see what they come up with.
 
I wonder how much they know about any potential weaknesses such a product might have. Maybe it's too early and later on they will find they have to change technique because ____ was causing ____ defects. It will be fascinating to follow.
I did hear they cannot do magnesium (I guess it would ignite) and chrome-moly (they did not say why).
 
Neat video. This is what stood out to me....
15 years of development and testing.... Wow... How would you like to be the one asking for approval on that project?

The job security would be nice once approved.

Quality control testing should answer that.
