Why is Apple so successful with its new designs? Well, one answer is that it breaks the rules when it comes to injection molding. One of the basic rules taught to new industrial designers is to always leave a draft angle so molded parts can be easily slipped from a mold cavity. Apple’s Designer-in-Chief Steve Jobs said the heck with that, according to an article in the current issue of MIT’s Technology Review. Apple designs computer housings with zero draft. It costs more for special ejection, but Apple achieves a unique box-like look. It also means designers can pack more in the housing and money is saved on packaging and shipping costs. But concept is king at Apple. Apple also makes extensive use of a two-shot molding process it calls “double back”.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
