Three-dimensional printing kit with polymer and fusing agent
The patent US12070899B2 describes a three-dimensional printing kit that includes a specialized powder bed material composed of various polymer particles, such as polyamide and polystyrene, along with optional inorganic fillers like alumina and titanium dioxide. A key feature of this kit is the inclusion of a redox-active inorganic salt, which can react with specific metal cations to produce water-insoluble colored pigments. The fusing agent, which consists of water and an electromagnetic radiation absorber, is designed to selectively apply heat to the powder bed material, facilitating the fusing of polymer particles during the printing process.
Additionally, the patent outlines a method for creating three-dimensional printed objects by layering the powder bed material and applying the fusing agent. The process involves exposing the layers to electromagnetic radiation, which activates the absorber to generate heat, thereby fusing the polymer particles. The method also allows for the incorporation of the redox-active inorganic salt to create colored pigments upon exposure to target metal cations. The claims further specify the composition and proportions of the materials used, ensuring versatility and effectiveness in the three-dimensional printing process.
