En passant des mati\u00e8res plastiques au b\u00e9ton \u00e0 prise rapide, l\u2019impression 3D ouvre des perspectives inou\u00efes \u00e0 l\u2019architecture et au secteur de la construction. Et la pr\u00e9sence d\u2019une imprimante 3D sur chantier n\u2019appara\u00eet plus si incongr\u00fce.<\/span><\/p>\n<\/div>\n

construction et imprimante 3D<\/span><\/h1>\n

Il fallait s\u2019y attendre. Depuis quelques ann\u00e9es d\u00e9j\u00e0, l\u2019imprimante 3D, con\u00e7ue pour produire en trois dimensions des corps dessin\u00e9s en CAO, sert \u00e0 r\u00e9aliser maquettes et mod\u00e8les, voire des \u0153uvres d\u2019art \u00e0 l\u2019\u00e9chelle 1:1. Au lieu d\u2019appliquer de la mati\u00e8re en plan, elle d\u00e9pose \u00e0 chaque passage de la mati\u00e8re en \u00e9paisseur, en montant d\u2019un cran lors du passage suivant. <\/span><\/p>\n

Voici deux exemples en vid\u00e9o de projets qui mettent en oeuvre du b\u00e9ton \u00e0 prise rapide et qui rend la pr\u00e9sence de telles imprimantes sur les chantiers d\u00e9sormais possible construction et imprimante 3D.<\/span><\/p>\n

\u00a0imprimante 3D en Angleterre\u00a0<\/span><\/h2>\n

En Angleterre, le Centre de recherche Process innovants et construction de l\u2019universit\u00e9 de Loughborough travaille sur une imprimante appliquant du b\u00e9ton (3D Concrete Printing). <\/span><\/p>\n

Les dimensions n\u2019atteignent pas celles d\u2019un b\u00e2timent encore, comme le projet de l\u2019universit\u00e9 de Californie du Sud (voir ci-dessous). Le Centre d\u00e9veloppe des process permettant de mettre en \u0153uvre des \u00e9l\u00e9ments de construction complexes de mani\u00e8re automatis\u00e9e, afin d\u2019offrir \u00e0 la conception architecturale une libert\u00e9 jusqu\u2019ici limit\u00e9e par les techniques artisanales et leur co\u00fbt. <\/span><\/p>\n

On obtient, ainsi, des \u00e9l\u00e9ments d\u2019une r\u00e9sistance \u00e9quivalente \u00e0 95 % de celle d\u2019un b\u00e9ton banch\u00e9. Le cabinet d\u2019architectes Norman Foster Partners, avant-gardiste de la conception 3D dans l\u2019architecture, participe \u00e0 ces d\u00e9veloppements de la construction et imprimante 3D.<\/span><\/p>\n

\u00a0l’impression 3D aux USA<\/span><\/h2>\n

Dans une dimension adapt\u00e9e \u00e0 la r\u00e9alisation de structures classiques telles qu\u2019une maison \u00e0 deux niveaux, le d\u00e9partement de l\u2019universit\u00e9 de Californie du Sud, dirig\u00e9 par le professeur Behrokh Khoshnevis franchit le pas en 2011 : ce n\u2019est d\u00e9sormais plus une mati\u00e8re plastique, mais un b\u00e9ton \u00e0 prise rapide qu\u2019applique leur imprimante. <\/span><\/p>\n

Cet institut a con\u00e7u un \u00e9quipement qui, mont\u00e9 sur rails dispos\u00e9s de part et d\u2019autre d\u2019un chantier, devrait imprimer une maison jusqu\u2019\u00e0 R+1 d\u2019un seul tenant en 24 heures. Le process est appel\u00e9 \u00ab Contour crafting \u00bb. Il appara\u00eet que la Nasa investit actuellement dans ce proc\u00e9d\u00e9 et les premiers prototypes devraient voir le jour cette ann\u00e9e. <\/span><\/p>\n

Cette d\u00e9marche appara\u00eet comme la plus adapt\u00e9e \u00e0 la construction actuelle. De par ses composants assurant une prise rapide, le b\u00e9ton ne n\u00e9cessite plus de banchage pour le coulage. C\u2019est le trac\u00e9 de la buse distributrice, parcourant les \u00e9paisseurs des parois par passages successifs, qui y d\u00e9pose un cordon continu de b\u00e9ton liquide.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
