Abstract
Current laser cladding technologies have limited resolutions of about 50 μm. A new solution has been developed within the project ‘Nanomicro’ to improve the spatial resolution. The ‘micro hollow laser beam system’ and a deposition system for highly focused metal micropowders are innovative parts within a high-precision 3D micromanufacturing laser cladding platform. We demonstrate, here, a new hollow laser sintering concept that is aiming on more efficient laser cladding and manufacturing of highly precise and functional parts in the range of a few microns.
