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.
It is a benefit so long as people still realize they need some engineering background. The flaw comes in when kids think why do I need to go to school for engineering when the computer does all the work for me.
I agree. I guess what I was trying to say was.....with the way things are going....you used to need an engineering background to design things....now anyone can do it.....I just hope kids still learn the fundamentals. It's kind of like what I mentioned about calculators, just because it can do the math for you doesn't mean you don't need to know what it's doing.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
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.
