Chattanooga company hopes to break ground on 3-D-printed house this year

  3-D printing in architecture is growing—literally. Once limited to models and small pieces, the technology has recently been adapted to large-scale projects, like the world’s largest 3-D-printed concrete bridge in Shanghai, a stainless steel bridge in the Netherlands, and walls for U.S. military barracks. An Austin-based company has even begun selling plans for 3-D-printed

Swiss researchers develop high-tech floor that minimizes concrete use

Global construction continues to steam ahead, even while seemingly mundane building materials (like sand) become rarer and more precious, and construction industry’s carbon dioxide emissions contribute to global climate change. The building industry seems to be demanding new solutions, but scalable alternatives remain scarce. Enter the Block Research Group at ETH Zurich. The group, which is

Flexible 3-D-printed cement stretches the possibilities of concrete

Concrete is a ubiquitous building material, applied to the bulk of contemporary construction projects. While the sedimentary aggregate is commonly used due to its impressive compressive strength, it remains a brittle material subject to damage or failure during extreme environmental events such as earthquakes. In response to this inherent weakness, a team of researchers based out

Neri Oxman’s Fiberbots autonomously build human-scale structures

The MIT-based Mediated Matter Group, founded by architect and designer Neri Oxman, is well known for its groundbreaking explorations at the nexus of 3-D printing, design, and what Oxman refers to as “material ecology,” a term that covers projects ranging from a CNC-fabricated scaffold coiled with silk thread produced by 6,500 silkworms to a solid wooden chaise adorned

U.S. Army Corps of Engineers tests 3D-printed concrete barracks

A research team within the U.S. Army Corps of Engineers recently 3D-printed full-scale concrete walls in an effort to create quick-to-assemble barracks for field housing, according to Engineering News Record. The project, named Automated Construction of Expeditionary Structures (ACES), aims to engineer structurally efficient and safe concrete barracks with precast roofs and 3D printed walls. In their latest tests, they were able

This experimental concrete roof is half the weight of its peers

A research team led by Jamin Dillenburger, an assistant professor at ETH Zurich, has recently produced and installed a concrete ceiling shaped by 3D-printed sand formwork. Dubbed the “Smart Slab,” the 1000 square-foot ceiling is significantly lighter and thinner than comparable concrete ceilings. According to ETH Zurich, Dillenburger’s research group “developed a new software to fabricate the formwork elements,

The world’s largest 3D-printed structure unveiled in Nashville

On July 18th, Chattanooga-based architectural fabricator Branch Technology unveiled the world’s largest 3D-printed structure, a bandshell pavilion measuring 20-feet-tall and 42-feet-wide. The pavilion was first announced in Cambridge, Massachusetts during MIT’s 2018 International Association for Shell and Spatial Structures. The structure is located in Nashville’s emerging smart-city neighborhood, OneC1TY. Reported by Architect Magazine, the carbon

Brooklyn’s New Lab goes big with a tech hub for urban entrepreneurs

Meet the incubators and accelerators producing the new guard of design and architecture start-ups. This is part of a series profiling incubators and accelerators from our April 2018 Technology issue.  Located in a former shipbuilding space at the Brooklyn Navy Yard, New Lab is an 84,000-square-foot collaborative tech hub dedicated to entrepreneurs working on scalable technologies and products. New Lab supports companies in nine
