BIG debuts new 3D printed mycelium structure at Scandinavian industry summit

2024-10-25T16:24:00-04:00

A new design from BIG made using 3D printing and mycelium additives is being showcase at a manufacturing summit for industry stakeholders in Scandinavia. The firm says it is "aimed at exploring new ways to reduce spatial and material waste through additive manufacturing and bio-based materials."

I AM MSHRM came together as part of a collaborative effort between the Danish AM Hub , MDT A/S, Naturpladen.

The result, they say, is a rapidly deployable and can be assembled in modular components made from recycled plastic and then filled in with the mycelium additive. This element makes their erection possible without the need for scaffolding. This method likewise reduces the overall volume of printed material, replacing it instead with the mycelium composite in such a way that "significantly lower[s] the overall carbon footprint" according to the firm.

MIT team creates 3D-printed glass bricks for reusable construction

2024-09-21T12:31:00-04:00

MIT engineers have created 3D-printed glass bricks that could offer a new approach to construction with sustainable and reusable materials. These interlocking bricks, which offer similar strength to concrete, are designed for circular construction, allowing buildings to be disassembled and reassembled at the end of their life cycle.

The team, led by Assistant Professor Kaitlyn Becker and former MIT researcher Michael Stern, developed the glass bricks using a custom 3D printing technology from MIT spinoff Evenline.

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.

Researchers use cellulose and algae to create 3D printed architectural material

2024-02-09T13:46:00-05:00

Researchers at Chalmers University of Technology in Sweden have published their study into how materials made from nanocellulose and algae can be used as sustainable architectural materials. The research, conducted in collaboration with the Wallenberg Wood Science Center, “shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods,” according to the team.

Nanocellulose, molecules consisting of hundreds or thousands of carbon, hydrogen, and oxygen atoms, are already used in biomedicine to 3D print scaffolds for tissue and cell growth but have never been used in an architectural material. The researchers, therefore, mixed nanocellulose fibers and water with an algae-based material called alginate to produce a 3D printable material with architectural uses in mind.

Termite mounds hold secrets for energy-efficient buildings, researchers find

2023-05-30T10:58:00-04:00

Researchers have uncovered a methodology for reducing energy consumption in buildings by studying the structure of termite mounds. Led by Lund University’s Dr. David Andréen and Nottingham Trent University’s Dr. Rupert Soar, the research suggests that the properties of lattice networks in termite mounds, known as an ‘egress complex,’ can be copied to optimize the interior climate of buildings.

“Here we show that the ‘egress complex’, an intricate network of interconnected tunnels found in termite mounds, can be used to promote flows of air, heat, and moisture in novel ways in human architecture,” said Andréen about the study, which was recently published in Frontiers in Materials.

With OpenAI’s new 3D model tool Shap-E, text-to-3D printing may soon be a reality

2023-05-10T12:11:00-04:00

OpenAI, the company behind AI applications such as ChatGPT and text-to-image tool DALL-E, has unveiled a new model that allows users to generate 3D objects from text or images. Named Shap-E, and available for free on GitHub, the tool generates 3D objects that can be opened in Microsoft Paint 3D and converted into STL files for use in 3D printers.

Unlike ChatGPT and DALL-E, Shap-E does not operate over an online application and is instead downloaded onto a PC for local use. The tool works in three modes: a ‘text-to-3D’ mode that uses text prompts to generate models, an ‘image-to-3D’ mode that turns a 2D image into a 3D object, and ‘encode-model’ which takes an existing 3D model and transforms it into another model.

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.
