EOS and GF Machining Solutions have entered a strategic partnership that will combine conventional and additive manufacturing processes
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.
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.
A 3D printed, platinum thruster chamber has passed a ‘baptism of fire’ when being hot tested by Airbus Defence and Space for the European Space Agency (ESA) in a world first
Microelectromechanical systems (MEMS) have been made available to the laser welding and cutting markets due to a new mirror coating developed by the Fraunhofer ISIT and IWS groups
TWI and the University of Cambridge have created the world’s smallest weld in thermoplastic material. The research could satisfy industry calls for welds in plastics below 10μm.
As part of the EU’s HALO project (High power Adaptable Laser beams for materials processing), scientists at the Fraunhofer Institute for Laser Technology ILT are working on distributing a laser beam’s intensity in a way that meets the highest quality requirements for laser cutting, while conserving resources
A new laser welding technology that creates safe contacts between temperature-sensitive battery cells has been developed by the Fraunhofer Institute for Laser Technology (ILT)
As the result of a Research Executive Agency (REA) funded project, Fraunhofer ILT and partners have found that Ultra-short laser pulses can modify material surfaces to allow easier adhesion of metal powder from a low-pressure cold gas jet.
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.
Matthew Dale explores some of the latest technology for manipulating and measuring the beam, including a multi-spot optical module for laser brazing and a contactless beam analysis device
Moving to very high power lasers for welding metals, like aluminium in car production, has some big benefits, as Greg Blackman finds out
