This item wasn't made using a 3D printer, but it will help those in less fortunate countries. Kodjo Afate Grikou, a 33-year-old in the African naiton of Togo, used his imagination, talent, and ambition to create the first 3D printer built entirely out of e-waste and scrap metal. He funded his project on the European social funding website ulule this year. The W.Afate project received more than $5,500. The printer cost him only about $100 to build. He hopes members of his community will print things like basic kitchen wares that aren't relatively available in West Africa. He also hopes that the printer will give young people hope and help answer the question "Why is Africa always lagging behind when it comes to technology?" (Source: Hackaday.com)
Yes, 3D printing has been around a while. Part of the recent explosion in interest in it stems from the name -- 3D printing. I wrote about stereolithography 20 years ago and there wasn't much interest in it. Similarly, the use of the terms "selective laser sintering" and "fused deposition modeling" didn't send anyone's heart racing, either. But the name "3D printer" captured the public's interest, and captured the interest of the mainstream press, even though many "3D printers" don't look like printers at all. The clever name will ultimately allow the world to consider it long enough to see the amazing things a that an FDM machine or SLS machine can do.
Thanks for the history lesson, Chuck. I've been wondering where this techology came from. It seemed like it popped out of nowhere. As well as being an attractive name, 3D printing clearly describes the object's function.
Good news, whic is that those expensive spools of plastic are not at all the only way to print with plastic. A mechanisation quite similar to a hot glue gun can dispense small drops of molten plastic, which can be from ordinary regrind plastic. LOts cheaper and available in a whole lot more places. And the mechanism may even be simpler than the feed for the plastic string stock. The main downside is needing to reload a bit more often. But extruding drops of melted regrind is a great way to make things indeed.
I think the prosthetic hand points to the future. Imagine if stem cells taken from your body could be grown and printed to form a new replacement body part that was genetically the same as the owner. There would be no rejection issues. I believe this will happen, just a matter of time.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Procurement actually means well. There is no question that procurement can do a better job of phrasing their questions or making connections between engineering’s goals and the processes underway. And if you are using the right deciphering code, the result can live up to -- or surpass -- your expectations.
If you are interested in adding FPGA technology to you engineering toolkit, grab some free tools and an evaluation kit and get started on your own FPGA project. It never hurts to expand your engineering toolbox, and FPGAs are only going to become more popular over the next few years.
