METHOD FOR PRODUCING LASER-SINTERING METALLIC COLLOID

摘要

To provide a laser-sintering metallic colloid, and to provide a method for producing the same.SOLUTION: A laser-sintering metallic colloid is formed by dispersing metallic material powder uniformly on a polymer comprising bisphenol A ethoxylate (BPA-EO), xylene, and polyoxyethylene fatty acid ester. The laser-sintering metallic colloid of this invention is to be provided directly in a region to be repaired of a workpiece when applied to 3D printing, whereby it can solve such problems as blowing away powder due to conventional 3D printing, eliminates the need for additional installation of a powder-collecting system, reduces the usage and waste of a metal powder, and reduces a processing cost.SELECTED DRAWING: None
