Strength

Ann, this is interesting news.  One question I would have is on the strength of the materials.  In general, machined materials are stronger than injection molded materials.  Of course, if the strength is enough for the purpose, then that is enough.  Then the speed of manufactur is all important.

Lou, the strength of the PM/sintered titanium powder metal parts produced by Dynamet has received approval from Boeing for use in structural aircraft parts, after a few years of testing. That news is pretty amazing on its own. The fact that Airbus has signed on to the Aeroswift aircraft structures project to help test selective laser-sintered titanium parts is another vote of confidence. It will be interesting to see what happens during that test phase.

Great article Ann. I always like learning about the new things they are doing with 3D printing. Titanium now, what's next? Keep the articles coming!

@naperlou: Selective laser sintering typically doesn't yield a fully-dense part, so the mechanical properties would be significantly inferior to those of a forging.  On the other hand, it has been shown that selective laser sintering followed by hot isostatic pressing can give mechanical properties equivalent to conventionally-processed titanium.

It seems like a good move for South Africa to go from an exporter of raw materials to a manufacturer of high-tech components.  Other developing countries could benefit from this example.

Ann, do we know how big the printer is, or how big the parts can be?

Chuck, I looked all over for build volume and printer size with no luck. The only clue is that it's designed to build components of large aircraft structures. I'm guessing several feet per side of build volume. Very large 3D printers exist in architectural apps for use with sand and soil and their build volumes can be 2m x 2m x 5m up to 6m x 6m x 2m, and even larger in the works.

Ann - thanks for offering the large size baths that are still being developed.  I had no idea that 3D makers were developing apparatus that large. 6 meters square-?  That's enormous. That's about 50 feet across diagonal; large enough to make a wingspan frame.  Wow.

Jim, note that those huge build volumes are for building architecture apps, not for aircraft. We don't know the build volume of the Aeroswift machine.

OK, noted;  do you know an example of the architectural Apps -?  I'm fuzzy on that, and wondering if it's a stretch between architectural and aeronautical ,,, ?

Jim, the architectural apps are for buildings. If you google "3D printed buildings" you'll find several different versions. Unless you want to make airplanes out of sand and cement, there's no relationship in products. But figuring out to make larger build volumes is, to some extent, a generic 3D printing problem, which is why I mentioned the larger build volumes of the architectural apps.

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
