mrdon, I kind of envy you in one way. You get to mold young minds. They have no preconceived ideas. When it comes to training in the work force, people come in thinking they "know it all". I have always been humble enough to know that every place is different and has a different way of doing things. I have taken on trainees that just refuse my help....they don't last long...lol It's really discouraging to see that. It is almost like they don't think I am trying to help them...I never did get it. I would see them struggling and try to help, and they would refuse. I was NEVER like that. That's the wrong way to be in my opinion. I think you learn where you can and you never stop learning. Some people seem to think they know it all, and they are the ones that fail.
mrdon, you did and then some. I appreciate it. People learn in different ways. I can just read a book, but some need another form. Well, that's why you're a teacher and I am not. I've trained in the work force, but never taught. I'll leave that to you guys. I bet it's very rewarding!
Cadman-LT, decision making will get even more complicated when third-party materials suppliers begin emerging, as Lux Research predicts is likely: http://www.designnews.com/author.asp?section_id=1392&doc_id=262205
Cadman-LT, What I found out in teaching engineering and technology to students is basically some folks have the ability to see complex subjects (ie math), thereby grasping the subject matter with little effort. Then, there are folks who learn by rote method requiring constant practice of the subject matter using reading and self-quizzing techniques for material retention. Last, there are folks who learn by building (tactile) stuff for visualizing the solution to the problem.
Belief it or not, Common Sense is not common in our society. One of the key elements to teaching is to relate the subject to the students' personal experiences. The result of this engagement technique is to allow learning the material through self discovery facilitated by the educator. The challenge for an educator is being able to make a quick assessment of the students in the classroom and to engage them based on some of the learning modes mention. I teach 4-1/2 blocks of electronics engineering tech courses and believe me, its educational entertainment at its finest! Hope I answered your question.
mrdon, I was wondering something that maybe you can answer for me...being a teacher. Years ago I borrowed some books from a network engineer. Basically they were about policies and directories. Everything I read was stuff I knew....not from books...it's just the way I taught myself. It just made sense to do things that way. I just couldn't understand why someone would have to read a book to know this. So my question is, do some people seem to understand tech better than others? What I read...to me...was common sense...but they had to write these books for a reason. Maybe it's like math, some people just "get it" and some don't.
Ann, good point. My first deciding factor HAS to be material....go from there. Also, there used to be only a few manufacturers, but now everyone is getting in the market. I see that as a good thing though as prices are dropping.
Cadman-LT, I agree. I tell my Electrical Engineering Tech students just because you puncha bunch a numbers into a calculator and press the enter key doesn't necessarily give you the correct the answer. The potential answer needs to be checked against the original problem for proper validation.
Cadman, there are so many different 3D printers for so many different applications and material sets, that it would take me about as long as it would take you to create a list--probably longer, since I don't know what you're looking for. I suggest you search on 3D printing/printers on the DN website. We have tons of articles about lots of printers and uses.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
