Interestingly, Chuck, we were able to play a computer game even with punch cards. They had one game at the University of New Mexico. It was a Star Trek game. You had to avoid or kill Klingons. After you submitted your cards, you had to wait until the next day to find out whether you destroyed the Klingon ship, avoided it, or got killed by the Klingons. That was around the time of Pong.
Chuck, one of the biggest surprises to many people has been how much 3D printing of metal objects is going on and has been going on, for several years, especially in aerospace applications. And these are not just prototypes.
Charles , you are absolutely correct the way 3D technology is spreading every university should offer 3D printing courses with practical hands on experience to the students so that every student become familiar with this technology as 3D printing is the future technology every student should have knowledge about that . More institutes should offer this course in order to make the students well informed .
I'm glad to hear about this too--thanks, Rich. It makes sense that some of the first AM courses in US colleges would be about prototyping, not more complex production parts made with metals. Although Optomec's smaller metals printer, which we wrote about here http://www.designnews.com/author.asp?section_id=1392&doc_id=264842 is specifically aimed at university mechanical engineering and materials science programs.
Charles, I totally agree. In this day and age...if you are not on top of the technology, then you are behind it. You can't wait a year or two to get it, by then it's too late. It is almost so bad that you can't learn it fast enough. By the time you go through a year of college, what you learned is out of date. Crazy stuff.
Richard, great article btw. I am glad to hear they are teaching this. It is here to stay for sure and it is the future of prototyping. For them not to teach it would be a disservice IMO. The technology is cheap enough now for all universities to offer such programs. Thnaks for the article.
Richard, it's nice to know that NYU is offering a course in 3D printing. Some of the universities are very keen and fast to include the very latest technologies in their syllabus and starting certificate courses. I hope other universities will also follow similar models.
I, too, used punch cards in college, Rob. I would drop off my stack of cards to run my finite element models at the computer lab and come back the next day to pick up my printouts. Obviously, the idea of 3D printing wasn't even in the back of anyone's mind at that point. These days, colleges have to be quicker in offering new kinds of courses because the technology is moving so much faster today than it was in the punch card days.
Jennifer and Rob, When I was majoring in chemistry in college in 1969, we had to wait in line to use a new computer that read out our answers in Nixie tubes. It cost $5k - twice the cost of a car in those days, and it did what a scientific calculator on the store shelf hooks does today. But seriously, why did it take so long to develop 3D printing? Why so long from the Moog synthesizer to voice recognition? If I had been less lazy... The great thing about this class is that you could take just that one class and start a business. Of course you would have to stay ahead of technology. I recall that Wang Corporation thought word processing was the end of the journey.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
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.
