3D printers print ten houses in 24 hours. SHANGHAI, April 25, (Xinhua) -- A private company in east China recently used a giant printer set to print out ten full-sized houses within just one day. The stand-alone one-story houses in the Shanghai Hi-Tech Industrial Park look just like ordinary buildings. They were created using an intelligent printing array in east China's city of Suzhou. The array consists of four printers that are 10 meters wide and 6.6 meters high and use multi-directional automated sprays. The sprays emit a combination of cement and construction waste that is used to print building walls layer-by-layer. Ma Yihe, the inventor of the printers, said he and his team are especially proud of their core technology of quick-drying cement. This technology allows for the printed material to dry rapidly. Ma, who has been designing 3D printers for 12 years, said the new technology is cost-effective and environmentally friendly. "But with the 3D printing, we recycle mine tailings into usable materials.

" Pao on Monday took to Reddit to address an issue that flared up over the weekend after the company fired a popular administrator, and used the opportunity to say sorry for problems that date back years. Meanwhile, an online petition launched three weeks ago calling for her resignation now lists more than 190,000 signatures, just shy of the 200,000 milestone. That number represents about 1 percent of the nearly 164 million visitors Reddit tallied in June, 3 million of whom logged into the service.
Reddit said more than 36 million accounts have registered on its service. In her post, Pao acknowledged missteps reaching back "over the past several years. The Change.org petition accuses Pao of ushering in "a new age of censorship" on the community-curated news site and adds that some users worry that Pao will "run Reddit into the ground.

Les incroyables promesses de l’impression 3D - Innovation produits. En quelques trimestres, l’imprimante 3D, née dans les années 1980, est passée du statut de curiosité à celui de machine utile dans le monde professionnel, y compris dans la construction.
Revue des possibilités. Imprimer une… maison. Gutenberg en perdrait son latin. Et pourtant, c’est ce que certains prétendent réaliser un jour au moyen de machines comme celles du Britannique D-Shape, de l’allemand Voxeljet, ou encore des grues-portiques robotisées de « contour crafting » imaginées par le professeur Khoshnevis de l’USC (University of Southern California).
Un peu futuriste, certes, mais pas tant que cela si l’on en croit le designer François Brument (voir ci-dessous). En attendant, ce qui est bien réel, c’est l’engouement mondial pour les imprimantes dites « 3D » : 55 000 unités vendues en 2013, 49 % de plus qu’en 2012 selon le cabinet de conseil spécialisé Wohlers Associates.
