3D-Printing — Lightweight Materials Inspired by Nature

Inspired by natural cellular structures, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (Seas), the Wyss Institute for Biologically Inspired Engineering at Harvard University, and MIT have developed a new method to 3D print materials with independently tunable macro-and microscale porosity using a ceramic foam ink.

Eager eye: The 3D camera detects the exact position and layer height of the pens by scanning the complete top layer in the bulk box after each pick of the robot. This image allows the pens to be taken out of the box with high-level precision. (Lukas Gojda/Fotolia.com, Schubert Packaging Systems, [M]-Sahlmüller)
Packaging Solution

Automated Handling of Sensitive Products with Novel 3D Technology

In order to expand its capacities and modernise its packaging line, those responsible for the location of a large biotechnology firm in the Netherlands were looking for a new system to pack vials and pens in different configurations. Automating this small-component packaging task would open up the possibility of increasing efficiency and saving production costs. At the same time, the chosen packaging solution needed to offer a high level of flexibility and precise handling.

The image, created with OPT, shows the pancreas of a healthy mouse. The individual pancreatic islets have been color-coded and their exact volume and 3D-coordinates can be precisely determined throughout the pancreas. The exocrine pancreatic tissue (in grey) has partly been digitally removed.  (Ulf Ahlgren)

3D Visualisation: New Tool in Diabetes Research

Swedish scientists have developed datasets that are able to map the three-dimensional distribution and volume of the insulin-producing cells in the pancreas. The visual and quantitative data of this development could become a valuable reference resource for diabetes researchers. The Umeå University researchers are publishing these datasets in the Nature Research journal Scientific Data.

The laser printing technique: by printing copper and gold in turn, the gold helix initially is surrounded by a copper box. Etching the copper away, results in a free standing helix of pure gold. (University of Twente)
The Netherlands: 3D Printing

Printing Pure Gold Microparts

Thanks to a laser technique that ejects ultra-tiny droplets of metal, it is now possible to print 3D metal structures, not only simple ‘piles’ of droplets, but complex overhanging structures as well: like a helix of some microns in size, made of pure gold. Using this technique, it will be possible to print new 3D micro components for electronics or photonics.

Nanostructured Tubes Could Make Water Electrolysis More Efficient and Flexible

Working together with external partners, chemists, materials scientists and chemical engineers at FAU have developed an innovative microcell for water electrolysis. They hope to replace standard plate electrodes used to split water into oxygen and hydrogen with compact, nanostructured tubes. They aim to simplify production, increase flexibility of use and avoid the need for expensive precious metals.
