3D Printing Flies High
10/15/2012

Paramount, a 3D Systems company, has made several non-structural flight hardware parts for Air Force fighter jets using its high-temperature laser sintering (HTLS) process. Shown here are a PEEK carbon fiber composite air duct (top), and technology demonstration parts (bottom) made of PEEK carbon fiber (black) and an unfilled PEEK (yellow).

3D printing in the field

Nice indepth account of how 3D printing is really changing the game when it comes to creating production parts from a wide variety of materials and in a much shorter time span. Beyond the implications in the aerospace applications you mentioned, Ann, the experimentation going on to use less expensive and more portable 3D printers in army applications, in the field, as a means of helping troops with extra parts they need or more significantly medical care is really exciting.

Thanks, Beth. The DoD's desire to make 3D printing accessible and useful for soldiers is apparently one of the main forces behind the formation of NAMII, the additive manufacturing initiative/consortium we covered: http://www.designnews.com/author.asp?section_id=1392&doc_id=251513

Seems like the dual forces of interest from the DoD and the commercial business sector could do a lot to advance the cause of 3D printing and additive manufacturing well beyond where it is today. Couple that with all the activity on the consumer front and you've got the real makings of a market.

I agree--the fact that 3D printing, in all its variety, is now on the radar of so many people and organizations bodes well, as does the spread of machines, and more and more materials, across the different market segments.

Nice article, Ann. I didn't realize that 3D printing had moved so far beyond creating prototypes and into finished parts. Quite impressive.

Another great article Ann. I like all of the new 3D methods and especially all of the new materials. It just keeps getting cooler!

Thanks, Cadman, glad you enjoy my blogs on this subject. I agree, the rate of advances has really sped up lately.

I really like the new materials. that's been my fascination with 3D printing thus far. The software advancements are good, but the materials determine what you can make. Wonder what's next?

One more thought. One thing that comes to mind to me, being an ex-machinist is the precision i.e. tolerances they can hold. I am betting they get better at that. You can print something all day long with whatever material, but if you can't hold certain tolerances then it isn't good for precision work.

I agree about tight tolerances. The fact that this technology is being used in commercial aircraft and medical applications speaks volumes about its success in achieving consistent, repeatable, very tight tolerances.

I couldn't agree more. I'm a little worried for some machinists out there. I can see these printers taking their jobs.

Then again, it should also create jobs. Instead of running a CNC lathe or mill, you run a 3D printer. It's a little weird to even think about.

That person would still need machining knowledge. At least knowledge of the measuring tools. I can see it as a trade school thing. Now instead of going for machining you go for 3D printing. I might be wrong, but it seems possible.

Ann, I just wanted to say. I know I go on and on about this 3D printing, but it just fascinates me to no end. We talked just a few months ago about materials and they are already here. Like you said, it's progressing very fast. I'm just really interested in this.
