Get Ready: 3D Printing Will Explode Next Year, When Key Patents Expire - Christopher Mims Here’s what’s holding back 3D printing, the technology that’s supposed to revolutionize manufacturing and countless other industries: patents. In February 2014, key patents that currently prevent competition in the market for the most advanced and functional 3D printers will expire, says Duann Scott, design evangelist at 3D printing company Shapeways. These patents cover a technology known as “laser sintering,” the lowest-cost 3D printing technology. Because of its high resolution in all three dimensions, laser sintering can produce goods that can be sold as finished products. Whenever someone talks about 3D printing revolutionizing manufacturing, they’re talking about the kinds of goods produced by, for example, the industrial-grade 3D printing machines used by Shapeways.
IBM invents ’3D nanoprinter’ for microscopic objects Illustration: a hot tip triggers local decomposition and evaporation of chip substrate material to etch patterns (credit: Advanced Materials) IBM scientists have invented a tiny “chisel” with a nano-sized heatable silicon tip that creates patterns and structures on a microscopic scale. The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that scans the surface of the substrate material with the accuracy of one nanometer. Unlike conventional 3D printers, by applying heat and force, the nanosized tip can remove (rather than add) material based on predefined patterns, thus operating like a “nanomilling” machine with ultra-high precision. IBM scientists have invented a tiny “chisel” with a heatable silicon tip 100,000 times smaller than a sharpened pencil point. Using this nano-sized tip, which creates patterns and structures on a microscopic scale, scientists etched a magazine cover in less than two minutes onto a polymer.
Nasa tests 3D-printed rocket engine fuel injector 15 July 2013Last updated at 08:24 ET Nasa says 3D printing could one day be used by astronauts to make replacement parts Nasa has announced it has successfully tested a 3D-printed rocket engine part. The US space agency said that the injector component could be made more quickly and cheaply using the technique. Deltaprintr - A simple, affordable 3D Printer! by Deltaprintr We engineered the Deltaprintr to be simple, efficient, and affordable. We want as many people as possible to be able to get their hands on this exciting new technology without having to sacrifice quality or user-friendliness. SIMPLE - Using a 3D Printer shouldn't be a hassle. We designed our printer so that it requires minimal set-up, and so that there's effectively no long-term maintenance.
markus kayser: solar sinter 3D printer jun 28, 2011 markus kayser: solar sinter 3D printer ‘solar sinter’, a solar-powered 3D printer by markus kayser, utilizes the abundant desert resources of sun and sand to manufacture products How to make big things out of small pieces MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child’s construction toy. The new material, the researchers say, could revolutionize the assembly of airplanes, spacecraft, and even larger structures, such as dikes and levees. The new approach to construction is described in a paper appearing this week in the journal Science, co-authored by postdoc Kenneth Cheung and Neil Gershenfeld, director of MIT’s Center for Bits and Atoms.
Explainer: What Is 4D Printing? Additive manufacturing – or 3D printing – is 30 years old this year. Today, it’s found not just in industry but in households, as the price of 3D printers has fallen below US$1,000. Knowing you can print almost anything, not just marks on paper, opens up unlimited opportunities for us to manufacture toys, household appliances and tools in our living rooms. But there’s more that can be done with 3D printed materials to make them more flexible and more useful: structures that can transform in a pre-programmed way in response to a stimulus. The green 3D printing materials we’ve been waiting for There’s no denying that 3D printing has moved beyond the laboratory and into the mainstream. We’ve seen 3D printed body parts, electronics, and toys. Although the technology has quickly become quite sophisticated, the materials used in 3D printers have been slow to catch up. Though the idea of print-you-own has big green implications, there’s nothing earth-friendly about an uptick in plastic junk floating around the planet.
Continuous liquid interface production of 3D objects Additive manufacturing processes such as 3D printing use time-consuming, stepwise layer-by-layer approaches to object fabrication. We demonstrate the continuous generation of monolithic polymeric parts up to tens of centimeters in size with feature resolution below 100 micrometers. Continuous liquid interface production is achieved with an oxygen-permeable window below the ultraviolet image projection plane, which creates a “dead zone” (persistent liquid interface) where photopolymerization is inhibited between the window and the polymerizing part. The audacious plan to end hunger with 3-D printed food - Quartz Uber is slavery…Uber will add to traffic congestion…Uber destroys the savings of cab drivers… Hold the litany. Is this the incumbency speaking? And my name isn’t Marie Antoinette. I might get in trouble for this, but I’d like to add a drop of customer experience into the boiling broth of opinions about Uber.
