Application: Post-processing of an object obtained by direct metal laser sintering (Patent ID: US20230321727A1)

The patent by Koninklijke Philips NV describes a method and system for treating the surface of an object created through direct metal laser sintering to achieve a smooth surface suitable for medical imaging systems. The method involves post-processing the object with surface optimization technology to reduce surface roughness, measuring the roughness, and determining if it meets specific conditions. The surface optimization technology includes techniques like sand blasting, electro polishing, and laser polishing, among others, to remove grains attached to the surface.

Furthermore, the patent outlines specific conditions for the post-processing surface roughness range, requiring it to be smaller than the initial roughness range by a factor of at least two and smaller than the maximum grain size of the metal powder used in sintering. The system for implementing this method includes a surface optimization unit, a measurement unit, and a determination unit to ensure the surface treatment meets the specified conditions. Overall, the invention aims to improve the surface quality of objects, such as X-ray anti-scatter grids made of materials like tungsten or molybdenum, by effectively removing surface imperfections left by the sintering process.
