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).
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.
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.
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.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
