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)
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.
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.
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.
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.
Machine vision and video streaming systems are used for a variety of purposes, and each has applications for which it is best suited. This denotes that there are differences between them, and these differences can be categorized as the type of lenses used, the resolution of imaging elements, and the underlying software used to interpret the data.
As today’s product design cycles are held to tighter schedules and budget constraints, it’s becoming even more critical to consider human factors up front to catch and fix problems during the initial development stages, when it’s faster and less costly to do so. Overlooking human factors at the beginning of the design cycle could lead to poor user experience, a decrease in effective product performance, and an increase in safety risk to the user.
Plastic part manufacturers are always looking for ways to reduce cycle time and get more productivity out of their injection molding machinery. One of the longstanding constraints in injection molding production has been cooling time. Removing parts from the mold before they have cooled induces warping or shrinking. But wait time works against productivity.
Editor’s Note: This is part 1 of an in-depth look at six added-value opportunities -- adjacent to the aluminum extrusion option -- that OEMs can integrate to upgrade supply chain interactions from basic buyer-vendor transactions to critical collaborations on strategic, single-source solutions.
