Imprimantes 3D Dimension, prototypage et fabrication rapide, impression 3D. Newton 3D, une imprimante 3D métal disponible début 2014. Des maisons de 200m2 imprimées en 3D pour 4 300€ Il n’aura fallu qu’un seul jour pour fabriquer la première maison par impression 3D et c’est dans la ville de Shanghai que cela s’est passé il y a quelques semaines.
C’est la société Shanghai WinSun Decoration Engineering Co qui est à l’origine de ce baptême dans l’industrie de la construction et explique travailler depuis plusieurs années sur la machine et les matériaux de construction. L’imprimante 3D développée par le groupe chinois est imposante, elle mesure 32 mètres de long, 10 mètres de large pour 6,6 mètres de hauteur et permet de réaliser des murs en seulement quelques heures.

This Robot Can Print A Bridge Out Of Sand. Using soil or sand and some solar power, this little robot can 3-D print the walls for a single-story house or even a bridge in the middle of the desert.
“We wanted to use robotics to solve problems that can’t be solved by traditional construction methods,” says Petr Novikov, who built the printer along with Inder Shergill and Anna Kulik as a thesis project in 2012 at the Institute for Advanced Architecture of Catalonia. They decided to tackle the challenge of building in drylands and desert areas, where construction materials are limited and labor is especially difficult because of the heat. The design uses local materials, prints everything on site so there's no transportation involved, creates no waste, and is low-cost. It's somewhat similar to Markus Kayser's Solar Sinter, which also prints using sand. But this robot can use soil as well, making it more versatile, and it's also much smaller, so it's easier to move around. "I'm still working in the field," he says.

Fast 3D printing with nanoscale precision. 285-micron racecar (credit: Vienna University of Technology) Printing three dimensional objects with very fine details using two-photon lithography can now be achieved orders of magnitude faster than similar devices in a breakthrough by Vienna University of Technology (TU Vienna) researchers.
The 3D printing process uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a hardened line of solid polymer a few hundred nanometers wide. This fine resolution enables the creation of intricately structured sculptures as tiny as a grain of sand. “Until now, this technique used to be quite slow”, says Professor Jürgen Stampfl from the Institute of Materials Science and Technology at the TU Vienna. This progress was made possible by combining several new ideas. Faster printing for large objects too “The resin contains molecules, activated by the laser light. 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.

Printrbot sells its entry-level Printrbot Simple for $399, or $299 unassembled.
The model earned Make's endorsement as best value. Solidoodle has four models that range from $599 to $999. At the intermediate price point, Cube printers, made by Stratasys' rival 3D Systems, start at $1,299. 3D Systems doesn't have its own retail shops but sells Cube printers at Staples. (Read more: 10 hot gifts for the gadget lover) No matter the make or price point, consumers need to be aware that 3-D printers are tools, said Anna Kaziunas France, digital fabrication editor of Make magazine.
"Right now they're tools for people who want to make things," said Kaziunas France. Terry Wohlers, president of consulting firm Wohlers Associates, expects that makers and hobbyists will continue to drive sales, while average consumers will go to stores to have products printed. "We believe there is a consumer market and a very big one for the technology, but it won't be machines running at home," he said. Shapeways - Make & Share Your Products with 3D Printing.

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. 3D printing.
