Objective
- Microstructuring using short-pulse and ultra-short-pulse lasers in order to produce 2½D and 3D micro-structures
- Processing of flat and rotationally symmetrical components and freeform surfaces
Approach
- Picosecond lasers at 532 nm and 12 ps pulse length and fiber lasers at 1064 nm
- 5-axis positioning system for 3D laser ablation on 3D surfaces
- Generation of high-accuracy microstructures in dimensions < 10 µm
- Achievable surface roughnesses Rz < 1 µm
- Laser remelting of surfaces as a finishing and polishing process
Development objectives
- Production of precise, periodic microstructures to influence the tribological behavior
- Implementation of optical and haptic properties of functional surfaces
- Production of microstructure components as well as die and mold-making for hot stamping and injection molding
Benefits
- Production technologies for surface functionalization and microstructuring
- Highly flexible process for a wide range of materials
- Potential for process combination (EDM, micro-machining)
