Surface functionalization and microstructuring using laser systems

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)
