Either fast or precise – both cannot be achieved in the production of the finest polymer structures with the laser. Or maybe they can? Combining stereolithography and multiphoton polymerization should make it possible: Scientists at the Fraunhofer Institute for Laser Technology ILT are developing a machine for high-precision, cost-effective 3D construction technologies using both methods. On November 1, 2018, Fraunhofer ILT and its project partners launched the project “High Productivity and Detail in Additive Manufacturing through the Combination of UV Polymerization and Multi-Photon Polymerization – HoPro-3D”, which is funded by the European Union and the state of North Rhine-Westphalia.

Lasers with ultrashort pulses in the picosecond and femtosecond range are often referred to as ultrafast lasers. They are known for their ultra-precise ablation and cutting results. Unfortunately, processing with such lasers takes time. To address this issue, a new research project, funded by the European Commission, aims to make material processing with ultrafast lasers up to a hundred times faster.

Elucidating the Atomic Mechanism of Superlubricity

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
