Company develops new fiber-reinforced wood, concrete ink for 3D printing
Even though 3D printing is an emerging market and technology, aside from Defense Distributed’s gun, it seems like it has hit a plateau. You can make little or somewhat-bigger-than-little figurines, teacups and mugs that often have leaks, or fragile parts — such as gears — that you can include in a working item, but might quickly wear down. One of the things holding 3D printing back is the material used to print objects. A San Francisco-based company, Emerging Objects, has created new printing materials that aren’t just plastic, but composed of wood, concrete, and even salt. For the uninitiated, normal 3D printing is additive. A nozzle (or nozzles) squirts out a material — usually some kind of plastic in a gooey state — and meticulously dumps layers of plastic onto a base, following the schematics of a preset model. Emerging Objects has developed a wealth of new materials, such as paper (made from recycled newsprint) as well as a printable salt material.
