摘要
Provided is a method capable of enhancing the quality (interlaminar strength, void reduction) of a lamination shaped article and using a high-heat resistant resin, and which has low cost and good quality and does not use a process window, and enhances release properties of a support. A laser powder shaping method for fabricating a lamination shaped article, the method having a step for providing a powder material as a thin layer and a laser irradiating step for irradiating the provided powder material with a laser and thereby sintering or melting the powder material, the laser powder shaping method characterized by having a step for performing a surface modification treatment for generating or increasing the number of oxygen functional groups in a region irradiated by the laser before or after the step for providing the powder material, or before or after the laser irradiation step.
