Airbus, aerostructure manufacturer Aerosud, and the South African Council for Scientific and Industrial Research, are partnering to develop the biggest, fastest 3D printer possible for making titanium aircraft and satellite components.

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.
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.
@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.
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.
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.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
Nearly all the products in this latest crop of new adhesives target electronic and other components for consumer electronics and automotive assemblies. Some are alternatives to liquid adhesives, others are liquids that cure faster, and several stick well to multiple substrate materials.
