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)
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Design for manufacturing (DFM) in mold production means that mold designers evaluate the manufacturability of their molds in the early stage of mold development by collecting all relevant information and applying it to their designs. They also have to consider many other factors, including flow balance, structural stress, and assembly tolerance, in order to ensure successful molding production.
Some adhesives provide strong structural bonds but take hours to fixture and attain handling strength. The technologies that offer the fastest cure do not bear loads or withstand stresses. A new class of adhesives aims to make both stick.
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.
