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 ...

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 ...

Copper deposition to fabricate tiny 3-D objects

21-Jan-2016 - Scientists at ETH Zurich have developed a new method of 3D microprinting. This can be used to manufacture even tiny, partly overhanging structures easily and in a single step. One day, this could pave the way for the manufacture of complex watch components or microtools for keyhole surgery, for ...

Nanowalls for smartphones

07-Jan-2016 - Researchers at ETH Zurich have manufactured transparent electrodes for use in touchscreens using a novel nanoprinting process. The new electrodes are some of the most transparent and conductive that have ever been developed. From smartphones to the operating interfaces of ticket machines and cash ...
