3 D Printing & Additive Manufacturing

By combining biology and 3D printing, Lawrence Livermore National Laboratory (LLNL) scientists have created a reactor that continuously produces methanol from methane at room temperature and pressure.

In conventional 3D printing, a nozzle scans across a stage: depositing drops of plastic, rising slightly after each pass, and building an object in a series of layers. A new "on-the-fly" prototyping system from Cornell University allows the designer to make refinements while printing is in...

Researchers from Washington State University and the Department of Energy's Oak Ridge Laboratory have created a tunable shape-memory polymer. The shape-shifting plastic can “remember” its original shape and return to it after being deformed with heat or other forces.

Engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama, unboxed some special cargo from the International Space Station on April 6: the first items manufactured in space with a 3D printer.

Given NASA's unique needs for highly customized spacecraft and instrument components, additive manufacturing, or 3-D printing, offers a compelling alternative to more traditional manufacturing approaches."We're not driving the additive manufacturing train; industry is," said Ted Swanson, the assistant chief for...

The 3D printing industry has new offerings today, specifically cheaper, easier-to-use hardware and online marketplaces filled with predesigned files. MakerBot, for example, recently announced a new one-button MakerBot Mini. Files can be sent directly to the compact printer from a mobile phone or tablet...

Ideally, the concept of "on demand" shouldn't limit itself to pay-per-view movies. If 3D printers were widely available in every household, consumers could quickly "demand" and fabricate specialized food and other objects at the touch of a button. Scientists in the emerging field of "bioprinting" are even attempting to make it...

Cool Polymers Xyloy™ is an injection-molded zinc/aluminum alloy processed in conventional plastic injection-molding equipment and molds. The Xyloy technology enables 3D netshaped metal parts right from the mold. Xyloy requires no carriers or binders, and — unlike die-cast metal parts — imposes no...
