continues to demonstrate increased flexibility and adoption across a diverse range of applications. Most noticeably, it is becoming ‘smarter’ and more adaptable, allowing manufacturers to achieve more optimal processing while switching between different parts and batch sizes without having to completely redesign a production line. For example, AI is being increasingly
"The laser beam itself is being delivered and monitored with increasing levels of sophistication"
integrated as one of the key tools for automating complex tasks such as sensor parameterisation and process monitoring. Both are key to achieving closed-loop laser materials processing, where laser systems adjust their parameters on the fly using sensor data to achieve optimal processing at the workpiece. Positive results are already being observed in applications such as welding and additive manufacturing, where AI is not only helping to lower the number of defects occurring during processing – reducing material wastage – but also helping automate processes further. The laser beam itself is also being
delivered and monitored with increasing levels of sophistication, aided by innovative laser sources, new wavelengths, adaptive, multi-focal beam delivery optics and multi- sensor process monitoring solutions. Data-informed, intelligent laser systems
delivering beams in the infrared, blue and green wavelengths will be vital to address
the lightweighting and electrification efforts underway in the automotive sector. 3D printers are now seeing widespread
uptake for serial production among both automotive and aerospace manufacturers to further bring down the weight of parts. More and more certified parts are emerging with re-designed, optimal topologies achievable only through the flexibilities offered by additive manufacturing. These printers are also gaining AI, process monitoring and multi-laser functionality to better produce these lightweight parts. There are efforts to incorporate lasers delivering visible wavelengths into such printers to produce electrically conductive, lightweight parts made from reflective metals such as copper. Last, but certainly not least, the
accelerating development of increasingly higher-power ultrafast laser sources is another cause for excitement in our field that, when combined with emerging beam-splitting technologies, facilitate high-throughput surface treatment and cutting applications. With them, the creation of functionalised surfaces with tailored electrical, reflective, hydrophobic/philic and tribological properties becomes achievable at rates feasible for a range of critical industrial applications.
