In a lecture at the EPIC event, Micorelleus explained their achievements in high-quality industrial engraving, focusing on micro engraving for moulds and tools.
They are world pioneers offering a femtosecond five-axis laser service called cold laser ablation. It involves ultra-short laser pulses—a femtosecond is 10−15 second, that is one quadrillionth of a second, or 0.000,000,000,000,001 second.
So, what impact does femtosecond laser have in vehicle lighting?
The characteristics of cold laser ablation enable Microrelleus to offer new possibilities in prototyping: microstructuring, texturing or engraving over any material, and mold microstructuring absolutely burr-free, with very sharp edges and high-quality surface finishing on PMMA and PC prototypes, both for functional and design purposes. Before, with conventional technology, it was not possible to obtain such high quality detail in prototypes.
Microrelleus can create microstructuring for light purposes such as changing light direction, broadening light angle, amplifying light intensity, creating new texturing possibilities for light diffusion or even micro-optics. All these possibilities are applied by Microrelleus in an industrial manner because they work on moulds and tools in five axes, so all these new possibilities are applicable over any 3D shape.
