Karl--excellent post. If I may, is the material now available for any "additative" manufacturing process; i.e. 3-D printing, stereo lithography, etc etc. It certainly seems from your post the characteristics are very desirable and have definite applications. Just a thought.
Chain orientation in feedstock before machining can have a large effect on final dimensions. Machining top surfaces of extruded plate can cause internal stresses to release causing warp on a previously flat plate.
Mr Hebel has writtenn a useful article about the challenges found in machining some thermoplastics. All of the points that he made are certainly valid, and the suggested work-arounds will be helpful, no doubt.
But most of the challenges also exist when machining metal parts, except for the moisture absorbtion. The same tips apply when working to produce higher accuracy metal parts as well, although to a somewhat lesser extent. I just wanted to point that out to those who may need to give direction in the macchining of high accuracy parts.
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.
