ETH Zurich’s 3D printed sculpture oscillates between ‘opaque boundary’ and ‘transparent curtain’

2024-03-14T12:06:00-04:00

ETH Zurich has unveiled a 6.5-foot-tall lightweight shell fabricated from 3D printing.

Named 'Fluid Forms,' and created by the institution’s Digital Building Technologies group, the structure seeks to showcase “an innovative robotic additive manufacturing method that enables the printing of doubly curved thin shells more efficiently.”

The design of Fluid Forms was inspired by the Costa minimal surface, which belongs to a family of shapes that minimize area for a given boundary, resulting in a geometry with strong structural properties. In contrast to horizontal plane printing, the fabrication process sees the print paths align to principal curvature directions, which, according to the team, reduces the need for external support and enhances the precision and surface quality of the curved surface.

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.

MIT researchers develop rapid 3D printing process with liquid metal

2024-01-30T12:40:00-05:00

News is circulating about a novel method for 3D printing liquid metals that was developed by researchers working at the Massachusetts Institute of Technology (MIT) Self-Assembly Lab.

The invention can print furniture-sized components using molten aluminum and a ceramic nozzle graphite printer. They say their discovery works without re-melting the recycled materials, as is the case with many current technologies. It resembles a small furnace into which book-sized blocks of the material are fed. The technique, called liquid metal printing (LMP), creates material that is durable enough to withstand CNC milling and other steps in the post-design delivery process.

ETH Zurich researcher develops 3D printed insulation foam using recycled materials

2023-12-01T11:48:00-05:00

ETH Zurich has published details of new research into lightweight building components produced using 3D printing. Led by doctoral architecture researcher Patrick Bedarf, the Airlements project centers on cement-free mineral foams derived from recycled industrial waste.

Working within the institution’s Digital Building Technologies group led by Professor Benjamin Dillenburger, Bedarf’s project emerged from a doctoral thesis on lightweight insulating construction elements, and how complex shapes could be manufactured with fewer material inputs. Bedarf ultimately deployed a sustainable insulation material produced by the ETH spin-off FenX using recycled industrial waste.

FenX’s mineral foam material is mostly made from fly ash, a waste product from industrial blast furnaces. Bedarf’s process then deploys 3D printing to shape the material into bespoke building parts without the need for formwork, which is traditionally only partly reusable and more time-consuming.

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.
