En passant des matières plastiques au béton à prise rapide, l’impression 3D ouvre des perspectives inouïes à l’architecture et au secteur de la construction. Et la présence d’une imprimante 3D sur chantier n’apparaît plus si incongrüe. Il fallait s’y attendre. Depuis quelques années déjà, l’imprimante 3D, conçue pour produire en trois dimensions des corps dessinés en CAO, sert à réaliser maquettes et modèles, voire des œuvres d’art à l’échelle 1:1. Au lieu d’appliquer de la matière en plan, elle dépose à chaque passage de la matière en épaisseur, en montant d’un cran lors du passage suivant.

Voici deux exemples en vidéo de projets qui mettent en oeuvre du béton à prise rapide et qui rend la présence de telles imprimantes sur les chantiers désormais possible. 3D CONCRETE PRINTING, Royaume-Uni En Angleterre, le Centre de recherche Process innovants et construction de l’université de Loughborough travaille sur une imprimante appliquant du béton (3D Concrete Printing). 3D printers | 3D models | Rapid Prototyping | voxeljet. China building world's largest 3D printer to construct houses. June 25, 2014 A Chinese company wants to print entire houses using 3D printing. Qingdao Unique Products Develop Co Ltd, a local maker of 3-D printers, has unveiled the world's largest 3D printer last week at the 2014 World 3D Printing Technology Industry Conference and Exhibition held in Qingdao. This massive 3D printer has a build volume of 12 m x 12 m x 12 m.

According to Wang Hong, company's founder and CEO, the company has spent the last 6 months developing this giant printer. It weighs more than 120 tons and was assembled using cranes and other machines. The giant 3D printer is currently placed in the High-tech Zone of local 3D Printing Industrial Park and will be open to the public. One notable advantage of this new printer is its use of graphene glass fiber reinforced plastic as 3D printing materials, which is light weight, strong, corrosion-resistant, and environmentally friendly. 3D House Printer.

Jun 9, 2014 Arup, an engineering and design firm in UK, claims to have come up with a method for designing and 3D printing critical structural steelwork components for use in buildings and complex projects. "Arup engineers are pushing the boundaries of 3D printing to take the technology firmly into the realm of real-world, hard hat construction. " said Arup's Salomé Galjaard. Using the latest 3D printing techniques, or more accurately, 'additive manufacturing', the Arup team created a redesign of a steel node for a light weight structure that they say will make construction cheaper and less wasteful. "By using additive manufacturing we can create lots of complex individually designed pieces far more efficiently. " commented Galjaard. "This has tremendous implications for reducing costs and cutting waste.

The traditional method of manufacturing these steel nodes is still cheaper to produce today, but Arup expects that "this will change in the short term. " Images by David de Jong via Arup. DIY Mud-Brick Machine Builds Life-Sized, LEGO-Style Blocks. Rammed earth structures make great use of local and sustainable construction materials, but pressing and curing each layer can be tough to do for small-scale contractors or do-it-yourself types. Hence, this ingenious portable hydraulic press from MecoConcept, which can pump out finished blocks in thirty seconds right on site.

Set on wheels, the brick-making machine can be moved along as needed, requiring only one person to work it at a time. Styled after LEGOs, each pressed-mud building block is shaped with bumps and grooves on each surface for easy stacking and side-by-side placement. Seismic-resident, stackable up to two stories, these simple bricks pack a lot into a small unit. The device itself is in early-phase limited production, available for rent or sale (at least in France), ? And potentially very practical for certain kinds of projects (imagine: simple backyard sheds, emergency shelters and the like).

Fun Reminders of Childhood: Concrete Building Blocks | doyoulovewhereyoulive.com. How many times have you thought about the fun times you had with the world-renowned Lego bricks? And how many of you still enjoy playing with the little building pieces? Lego blocks have been around for decades and apparently, it was high time that real building blocks stepped up. The interlocking concrete bricks were hand cast to resemble a standard 2×4 LEGO building block and remind everyone about the great time they spent during their childhood pretending to build amazing structures.

Some architects might even consider this an exceptional gift, just like any other Lego fan. Use them to constantly remind yourself of the joys of a carefree childhood or give them away as presents to whomever you feel would enjoy them most. The concrete bricks are all unique due to the features of the material. Ready for more amazing design ideas? Click here to connect with Freshome on or on.

QuaDror / Home. 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. Aucune photo n’a toutefois été dévoilée pour le moment.

Le matériau d’impression utilisé est également innovant et éco-responsable, il s’agit d’un béton composé à base de ciment et de fibre de verre, issus de déchets de construction. Les dix maisons imprimées en 3D mesurent 200 m2 chacune pour un coût de seulement $4800, soit environ 4300€ ! Copyright photos www.news.cn. New photos of 10 'green' 3D-printed houses in Shanghai, built in 24 hours. April 14, 2014 In a first, a Chinese company has advanced the science of 3D printing by printing 10 houses entirely out of recycled materials, in just under a day. Earlier this month after we posted "10 completely 3D printed houses appear in Shanghai, built under a day", some commentors are complaining that the 3D printed house looks strange and that isn't real 3D printing. We don't see what their problem is. The parts, such as frame, wall were printed separately. The parts dry quickly and can then be used to assemble to a complete house.

This week the company behind the 3D-printed houses, Shanghai WinSun Decoration Design Engineering Co revealed more photos showing off the concept. 3D printed wall 3D printed frame An enormous 3D printer, measuring 32-meters long, 10-meters wide, and 6.6-meters high, was used to print each of the structural components of the houses. WinSun said the team finished the design of the special printer several years ago. L'imprimante 3D qui peut construire une maison en 24h. IMPRIMANTE 3D - En juin 2013, le blogueur américain, Randy Nelson estimait qu'il faudrait 220 ans pour construire une maison avec une imprimante 3D. Behrokh Khoshnevis, professeur à l'université de Californie du Sud, pense pouvoir faire mieux avec Contour Crafting, une machine capable de construire une maison de 225 mètres carrés en 24h (voir ci-dessous).

Un véritable gain de temps, d'argent et de moyens pour les constructeurs immobiliers. "Il s'agit juste, explique Behrokh Khoshnevis, de faire évoluer l'impression 3D classique à l'échelle d'un immeuble. " Comment marche cette merveille de technologie? C'est assez simple, Contour Crafting, utilise un système d'impression 3D classique, mais à plus grande échelle.

Le projet, actuellement en phase de test, a séduit la NASA qui à long terme envisage de l'utiliser lors de futurs voyages spatiaux. Maisons, desserts, jouets ou bien armes à feu, l'imprimante 3D sait décidément tout faire. Folding Concrete?! Flat-Pack Building Blocks of the Future. This may be the biggest invention since that long-standing, still-universal staple of the construction industry: the red clay brick.

A single identical unit, multiplied by four, forms a rigid structural element – stack these and set them side by side, and you have nothing short of a material revolution. Watch the videos to fully see how these function! Created by Dror Benshetrit after years of toying with related geometries and building methods, this super-simple, gravity-driven block system has as many applications as one can imagine. It could be used for short-term emergency shelters, on the one hand, or to hold up bridges for the long haul on the other. Think: Buckminster Fuller domes for the 21st Century. Uniform in shape and size, each pair expands outward to provide stability like (and require less space than) a conventional building block – they are symmetrical on both sides, but joined together are beyond tough to topple.

So how high can they go? Matériel pour construire en terre crue.
