Abstract: A powder shaping method comprises: providing a powder on a target surface; providing a laser beam to illuminate the powder so as to form a pre-treated powder; and providing an energy beam to illuminate the pre-treated powder for enabling a shaping process. In addition, a powder shaping apparatus comprises a base, a target surface, a powder supply unit and an energy beam source system. The target surface is disposed on the base and can be fixed or moved on the base. The powder supply unit provides a powder on the target surface. The energy beam source system has a laser source and an energy source, the laser source provides a laser beam to illuminate the powder to form a pre-treated powder, and the energy source provides an energy beam to further illuminate the pre-treated powder to make a shaping process.
