LLT.tube – FULLY AUTOMATED, MATERIAL FRIENDLY & µm-ACCURATELY LASER MICROMACHINING

Challenges in manufacturing and processing fine or precision tubes are complex. Especially high-tech industries such as medical technology, sensor technology or optics, expect not only high precision but also gentle treatment of sensitive and cost-intensive materials, as in the case of stents or hypotubes.

LLT.tube was developed to meet these expectations. Due to the use of an ultrashort pulse laser, the heat-affected zone and the associated thermal stress on the material are minimal, as are the feasible dimensions of the cutting or drilling contours. The material retains the desired properties and residues such as melt are avoided.
