ETH Zurich researchers develop robotic process for impact printing earth materials

2024-09-23T12:32:00-04:00

Researchers at ETH Zurich have introduced a new robotic 3D printing method for cement-free low-carbon materials for a circular economy.

Using a technique called 'impact printing,' the team demonstrated a mixture of excavated materials, silt, and clay that was less dependent on additives for its structural strength due to the high-velocity deposition process. Their aim was to "increase the cost competitiveness of sustainable building materials through efficient and automated production."

Princeton researchers develop concrete 3D printing method inspired by ancient fish scales

2024-09-05T08:00:00-04:00

Researchers at Princeton University’s Engineering School have developed a method for 3D printing concrete with improved crack resistance. Taking inspiration from fish scales, the team led by assistant professor Reza Moini claims their design increases resistance to cracking by as much as 63% compared to conventional cast concrete.

Princeton’s method drew inspiration from the double-helical structures that form the scales of an ancient fish lineage named coelacanths. The resulting design sees concrete arranged into individual strands, with robotic 3D printing used to weakly connect each strand to its neighbor.

“The researchers used different design schemes to combine many stacks of strands into larger functional shapes, such as beams,” Princeton explains. “The design schemes rely on slightly changing the orientation of each stack to create a double-helical arrangement (two orthogonal layers twisted across the height) in the beams that is key to improving the material’s resistance to ...

Why is technological progress still lagging in the building trade?

2024-05-27T11:00:00-04:00

Overall, across Europe and the US, stuff is still built in a pretty manual fashion - not very different to the way it would have been built 100 years ago [...] Construction is a bit of a digital laggard compared with many other industries. It's been slow to adopt digital in the widest sense

Consultant Sam O’Gorman and other experts speak to the BBC about the confounding gap between digital technology and the analog process for delivering residential architecture. Interesting projects mentioned are the University of Maine Advanced Structures and Composites Center’s attempts to develop the world’s largest 3D printer and the UK firm Automated Architecture (or AUAR)’s plan to create a network of ‘micro-factories’ capable of producing pre-assembled six-story timber design for just £250,000 ($320,000 USD) using robots.

IAAC/WASP team creates ‘solid and expressive’ 3D printed wall made from earth

2023-02-13T13:17:00-05:00

Barcelona’s IAAC has collaborated with Italian 3D printing company WASP on the creation of a 3D printed earthen wall. The element was printed from a mixture of clay and rice fibers, with interlocking timber beams providing support for stair and floor structures.

The 15.7-inch-thick wall was printed in 40 hours using 70 cubic feet of material. Printed in horizontal layers with voids left for the placement of cantilevering timber elements, the team describes their method as one that can “confer both solidity and aesthetic expressivity.”

The prototype was printed using WASP’s modular 3D printing system titled ‘Crane WASP.’ The machinery is composed of a main printer unit that covers an area of 538 square feet by way of a radial mechanical arm, similar to the operation of a traditional construction crane. The Crane WASP system has also been used to deliver the Mario Cucinella-designed TECLA raw earth home which we reported on in 2021.

Funding flows to construction technology start-ups

2019-07-24T09:36:00-04:00

Funding in US-based construction tech startups totals just $196.5 million across 44 deals halfway through 2019. Still, $192.6 million across 44 deals is still significantly lower than the $1.274 billion raised by US-based construction startups in the first half of 2018.

The bustling world of construction technology start-ups is off to a slow start in 2019, as mid-year funding statistics point to a marked drop in investment for these insurgent companies over 2018's blockbuster year, Crunchbase reports.

Whether or not 2018's record investment, including Katerra's $865 million haul, was a one-time fluke remains to be seen. Either way, that's not stopping funders from supporting companies like Rhumbix, a San Francisco-based field data-capturing platform that helps builders go paperless on the job site, which recently received a $14.3 million in new investment.

Trevor Zimmerman, managing partner at investment firm Blackthorn Ventures, told Crunchbase, “Today, foreman and laborers have supercomputers in the form of smartphones in their pockets,” adding, “That’s enabling companies like Rhumbix to bring efficiency gains to construction that other sectors, like manufacturing, were able to access over a decade ago with desktop computers.”

TyBot: a robot invented for tying steel reinforcement bars in construction

2017-11-16T13:47:00-05:00

Tybot is a robot recently invented that can tie together steel reinforcement bars saving time and reducing risk in construction projects. Thousands of joints must be tied before pouring the concrete, however this step has traditionally been labor intensive, hazardous, and a cause for major delays in the building process.

This robot is the first offering from the firm Advanced Construction Robotics (ACR) launched by construction firm boss Steve Muck and robotics expert Jeremy Searock. The machine only requires transportation and setting up the frame using the existing infrastructure, which can be done in half a day's work. TyBot is then ready to go to work, often at night, needing only one worker supervising it in operation.

Efficiency-enhancing drones could dramatically reduce construction costs

2016-09-27T13:32:00-04:00

According to this Fortune article, it's estimated that the construction industry wastes billions of dollars annually in poorly organized and distributed materials, a practice that could be eliminated with omnipresent flying drones. The trick is to create software that can process what the drones see on each construction site into data that humans can quickly comprehend and efficiently implement. Autodesk is investing in developing software and hardware that can convey this information, which may dramatically cut construction costs (and perhaps make architects rethink how they bill for projects).
