A dual-laser tube cutting platform for endovascular devices — femtosecond and fibre source, rotary axis with on-centre and off-centre kinematics, galvo scanner for secondary processing, wet and dry cutting modes. Five distinct process configurations on one machine architecture. Custom HMI development with recipe management, vision-based alignment, and operator-guided workflows. Led from first specification through process development, software integration, FAT, and installation at the launch customer. The system runs in medical device production today.
Co-development of a 3-axis femtosecond machine with scanner and cutting nozzle as interchangeable processing heads — for flat substrates or tubes. Rotary axis as optional module for tubular workpieces. All three linear axes German-made with < 5 µm accuracy. From system architecture through process integration to production qualification.
Laser welding validation across multiple part geometries from one design family. High volume of test parts for first qualification. Machine concept included part logistics upstream of and within the welding station, with inline quality assurance via vision system.
Batch processing of watch components across materials — from stainless steel to yellow gold. Custom fixture design, vision-based individual part alignment, and per-part laser programme generation. Nanosecond ablation for high-precision engraving on delicate surfaces. Process developed and qualified from first trials through parameter optimisation to series production integration.
Laser-induced periodic surface structures — structural colour without pigments. Process development using a polygon scanner at 240 W picosecond source and 800 m/s scan speed. Started at a research institute as a multi-year development programme. Not every process starts in an OEM laboratory — and not every solution exists as a commercial machine, standard or customised. Research institutes provide the environment for high-risk process development where everything needs to be rethought from scratch.
