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)
