NASA is using 3D printing to build engine parts for its next-generation Space Launch System. Shown here is the first test piece produced on the M2 Cusing Machine at the Marshall Space Flight Center. (Source: NASA Marshall Space Flight Center/Andy Hardin)
3D paper printers. 3D plastic printers. 3D metal printers. All create parts that are monolithic (granted, some 3D plastic printers can print two different types of plastic, or different durometers, but it's still plastic).
These are each steps into the future, where one machine will print multiple materials to make a complete item. A valve built complete with internal seals comes to mind.
Innovative idea for using the 3D printing process to make rocket components. Certainly part integrity needs to be tested, but in many cases, this process can make more complex parts for less cost with a faster delivery time. I expect this application of technology to grow in the future.
Even the best 3D printed part I have seen is not perfect. I would be hesitant to use anything "printed" in the propulsion sections of rocket tech where human life is involved. At least for now. It is a great first step on NASA's part. Perhaps their work will innovate the printing sector like their work has in many others.
I considered printing parts for a side company I did some work for, the quality I received was unsellable. This was after outsourcing to a company who had the latest. Perhaps in the future..
Ann, this is a great new process. If it works, it will be a great way to produce these complex parts. I wonder, though, whether they can eliminate all the welds. That would be great.
It is also good to see that there will be reuse of some of the existing rocket engine designs. After the Apollo program the Saturn 5 tooling was mostly lost. When the Shuttle was having problems NASA was in no position to use technology that had already been developed to fill the gap.
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.
