Conventional laser technology primarily addresses 2D-structures, e.g. flat metal sheets, wood panels. However, 3D –objects are far more sophisticated than flat ones. Consisting of multiple uneven surface layers, processing of such objects is a difficult undertaking which involves precise operation and control of multiple axes and handling systems.
LASHARE has developed a way to level up, goingfrom 2D to the third dimension. Complex 3D-Strucutures are found in a variety of products, such as the interior of a car, household appliances, or consumer electronics. The main obstacle for traditional laser systems is the processing of large workpieces with 3D –shapes; conventional beams are unable to reach very complex and remote parts because of a limited operating range and small beam diameters that make precise positioning a very difficult task.
LASHARE overcomes this issue by offering a very flexible and precise laser tool. Contrary to conventional 2D- laser tools, our laser beam can circle around the object during the texturing process (the process of creating permanent marks by using a laser beam), enabling it to reach every possible location on the workpiece, and exceeding the working range of every 2D-System.
The challenge we are tackling in LASHARE is to control the combined motion of the beam delivery system and the workpiece with respect to distortion of the motifs and positioning tolerances, so that even complex surfaces can be processed continuously. This enhances the continuity and uniformity of textures and provides a perfect customer perception.

Modern products possess ever more surface features, which require modern high-tech tools in the manufacturing process. Laser technology is predestined for the creation of fine structures, due to its contactless, tool-free handling. Therefore, laser surface structuring, which spans from ablation and scribing to engraving, can be used in almost every industrial manufacturing process, e.g. automotive, cellphone and TV production, photovoltaics and even coin minting.
A major application area for laser surface structuring is the production of thin-film organic photovoltaics and organic LEDs (OLED). Utilizing laser technology instead of conventional production methods offers not just higher precision and flexibility but also a very eco-friendly production, because of lower energy demands and less consumption of chemicals.
Laser surface structuring can be applied in large-scale mass production as well as for small and medium batch sizes. Its cost-effectiveness and the advantage of creating individualized structures, give companies a very powerful tool at hand.
By megawatt pulses at picosecond duration a layer from a material surface is vaporized without any thermal effects on the remaining material. The effect can be increased by applying multiple, ultra-short pulsed laser beams, which allow a contact-free and micrometer-precise (1/1000000th of a meter) removal of material without damaging surrounding areas.
This innovative laser-based technology demands particular requirements on optical components and design methods. Especially, the realization of simultaneous processing of multiple workpieces is not yet state-of-the art, but LASHARE is working on this and more.
