The materials have been costly, but the earlier machines were, too. Added to that, because items are produced one at a time the per unit cost tends to be higher than unit costs of a high-volume manufacturing process. And that's exactly why this technique is still limited mostly to specialty and race cars, not volume automotive manufacturing.
Direct Laser Sintering technologies as a means to help Unmanned Aerial Vehicles has definitely been on Design News' radar screen for a while and is a great application for this technology. We wrote about one of the first UAVs built with this method taking flight this summer--SULSA,the Southampton University Laser Sintered Aircraft, which was printed using the EOS EOSINT P730 nylon laser sintering machine.
Curious how expensive this process is. You mention aerospace, medical and dental, where high costs can presumably be absorbed. Given the durability and ease of assembly (by aggregating more subassemblies into one piece), DLS seems like it should have huge uptake in automotive, but I'm guessing at this point that it's just too expensive.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
