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”.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
