One or two technologies will dominate the additive manufacturing market in a few years, says David Reis, CEO of Objet Geometries of Rehovot, Israel. Determining factors will be similar to those that are important in two-dimensional printing, says Reis. They include: part size, speed, productivity and price. Critical factors in productivity are output in a given period of time, and extent of manual labor involved in the production. Reis made the comments in a press conference at Euromold in Frankfurt, Germany.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
NASA's JPL and Caltech have achieved the mind-boggling feat of 3D printing multiple metals in a single end-part, grading from one alloy to another. They've also developed a method for combining metals with carbon fiber composites in end-production parts.
