Robert--Very informational. Excellent post. Am I correct in saying the Tg temperature is somewhat like the "triple point" for other materials? Would this be a decent analogy? Also, I'm assuming all adhesives have a Tg temperature. In looking at the adhesives I use and see used on a daily basis, we are very concerned that we apply adhesive to a part and adhere that part to a substrate before that adhesives "skins over". The only way for us to insure compliance with our customers "pull test" requirements.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
