The rapid prototyping industry is growing a robust 32% a year, but has not realized the potential first envisioned when it emerged in the 1980s. Complexity and cost of ownership slowed its growth. It became almost cult-like with enthusiasts obsessing on fine details of machine technology. The industry needs to do a better job of reaching out to design engineers. It could be a perfect fit. Many engineers, particularly in the medical device industry design what they need, and then have to make compromises because of manufacturing constraints. The additive fabrication developed originally to make prototypes now has the potential to bust those constraints wide open because no molds are used and complex internal geometries are easily achieved. I’m thinking, for example, of jaws made for surgical instruments. Now, they are often injection molded from powder metal. New additive technology now allows parts such as jaws to be from laser sintering with internal channels of almost any design. Sure there are some drawbacks: less than perfect surface finish out of he machine, weak industry-wide standards, and lack of closed loop machine controls. But this is a marriage waiting to happen.
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.
