AM simplifies optical fibre production

Researchers at the University of Southampton’s Zepler Institute are set to investigate additive manufacturing techniques for fabricating optical fibre.

If successful, the process could help create complex fibres for high-power laser applications and the telecoms and medical industries.  

The team aim to simplify the production of optical fibre performs from which a fibre is drawn, and creates intricate internal structures such as bandgaps. This is currently one of the most difficult stages in the production of optical fibres.

LZH develops method for repairing diamond-edged blades

The Laser Zentrum Hannover (LZH) and the Institut für Werkzeugforschung und Werkstoffe (IFW) in Remscheid have developed a mobile, laser-based process chain for gluing the cutting segments onto a diamond saw blade and removing them subsequently without causing damage.

The processing of natural stone such as marble or granite is usually done with saw blades with hard-wearing, diamond cutting segments. When these are damaged or worn, the cutting segments have to be replaced.

Emissions analysis for laser processed plastics

Scientists from Laser Zentrum Hannover (LZH) and Kunstoff Zentrum SKZ, Würzburg have compiled information on the emissions being released when laser processing plastics. The centre said this was crucial in guaranteeing the safety of the operators and the environment. The results are now available from the Safety Technology Group at the LZH or as part of the laser safety database on the institute’s website.
