Programmable structures from the printer

Researchers at the University of Freiburg and the University of Stuttgart have developed a new process for producing movable, self-adjusting materials systems with standard 3D printers. These systems can undergo complex shape ...

Research team turns up the heat on 3D printing inks

A process that uses heat to change the arrangement of molecular rings on a chemical chain creates 3D-printable gels with a variety of functional properties, according to a Dartmouth study.

Multi-material, multi-photon 3D laser micro- and nanoprinting

Multi-photon approaches provide printing rates of up to about ten million voxels per second. Multi-photon-based 3D approaches structure matter with a resolution approaching sub-micrometer and nanometer feature sizes. Such ...

Novel materials: Sound waves traveling backward

Acoustic waves in gases, liquids, and solids usually travel at an almost constant speed of sound. So-called rotons are an exception: their speed of sound changes significantly with the wavelength, and it is also possible ...
