3D printing stem cells to transform neuroscience

3D printing, also called additive manufacturing, has become widespread in recent years. By building successive layers of raw material such as metals, plastics, and ceramics, it has the key advantage of being able to produce ...

Electron beam melting gets brittle metal into shape

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high-temperature furnaces, or the fusion ...

Ultrashort peptides go a long way for tissue engineering

A new automated process prints a peptide-based hydrogel scaffold containing uniformly distributed cells. The scaffolds hold their shapes well and successfully facilitate cell growth that lasts for weeks.

Direct 2D-to-3D transformation of pen drawings

Pen drawings can allow simple, inexpensive and intuitive two-dimensional (2D) fabrication. Materials scientists aim to integrate such pen drawings to develop 3D objects. In a new report now published on Science Advances, ...
