ETH spin-offs sweep the board at Venture Awards

30-Jun-2025 - Six spin-offs of ETH Zurich were among the 18 finalists in this year’s Venture Awards. Three of them won in their respective categories, and three came in second. The Grand Prize went to spin-off MyNerva. The MedTech company MyNerva clinched the Grand Prize worth CHF 150,000 at the Venture Awards ...

3D printed reactor core makes solar fuel production more efficient

Using a new 3D printing technique, researchers at ETH Zurich have developed special ceramic structures for a solar reactor

31-Oct-2023 - In recent years, engineers at ETH Zurich have developed the technology to produce liquid fuels from sunlight and air. In 2019, they demonstrated the entire thermochemical process chain under real conditions for the first time, in the middle of Zurich, on the roof of ETH Machine Laboratory. These ...

ETH Zurich researchers want to make salt printing marketable

They have also come up with a name for their start-up: “Sallea”, a portmanteau of “salt leaching”.

06-Oct-2022 - Materials scientists Nicole Kleger and Simona Fehlmann have developed a 3D printing process for creating salt templates that they can fill with other materials. One area of application is the creation of highly porous lightweight metal components. The two Pioneer Fellows are now trying to ...

Applying the butterfly principle

Researchers have created artificial colours by 3D printing certain nanostructures inspired by those of a butterfly

11-Feb-2022 - For their new technology, scientists in the group of Andrew deMello, Professor of Biochemical Engineering, drew inspiration from butterflies. The wings of the species Cynandra opis, native to tropical Africa, are decorated with brilliant colours. These are produced by extremely intricate regular ...

3D printing approaches atomic dimensions

A new electrochemical technique makes the production of complex metallic objects at the nanoscale possible

22-Nov-2021 - In recent years 3D printing, also known as additive manufacturing, has established itself as a promising new manufacturing process for a wide variety of components. Dr Dmitry Momotenko, a chemist at the University of Oldenburg, has now succeeded in fabricating ultrasmall metal objects using a new ...

Printing complex cellulose-based objects

27-Mar-2020 - Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher cellulose content than that of any other additively manufactured cellulose-​based parts. To achieve this, they used a ...

Honey, I shrunk Michelangelo's David

Researchers in Zurich have reproduced Michelangelo’s David as a miniature in metal

02-Jan-2020 - There he is, standing upon his pedestal: David by Michelangelo. A world-​famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-​meter original, but of pure copper. It was created using 3D printing ...

Glass from a 3D printer

27-Nov-2019 - ETH researchers used a 3D printing process to produce complex and highly porous glass objects. The basis for this is a special resin that can be cured with UV light. Producing glass objects using 3D printing is not easy. Only a few groups of researchers around the world have attempted to produce ...

3D printing of silicone components

22-Aug-2019 - ETH spin-off Spectroplast has developed a method to make silicone products using a 3D printer. The young company now plans to bring to market customised medical products such as hearing aids, breast prosthesis for breast cancer patients and eventually even artificial heart valves. Their ultimate ...

The stiffest porous lightweight materials ever

13-Dec-2018 - Researchers at ETH have developed and manufactured a family of architectures that maximises the stiffness of porous lightweight materials. It’s practically impossible to develop stiffer designs. 3D printing and other additive production techniques make it possible to manufacture materials with ...
