In the quest for on-demand, smart, sustainable, and decentralised manufacturing, digital servitisation offers high-quality, flexible production with quick turnaround times. However, this approach faces a hurdle: the lack of comprehensive methodologies. The EU-funded Lasers4MaaS project is stepping in to change this. Building upon the advancement of dynamic laser beam shaping to an 'all-in-one' laser welding tool with immense potential for servitisation, Lasers4MaaS introduces a six-point strategy to reconfigure, connect, control, predict, improve, and ensure compliance in manufacturing. With demonstrations in sectors like automotive, aerospace, food packaging, and renewable energy, this project aligns closely with Green Deal goals. A consortium of academic and industrial partners will bridge technology readiness levels and advancing standardisation.
