The invention discloses a 3D printer based on liquid-solid chemical reaction deposition and operating methods thereof, comprising a sealed forming chamber, a powder container, a forming container, a powder spreading mechanism, and a three-axis linkage mechanism in the sealed forming chamber. The three-axis linkage mechanism moves a nozzle in the sealed forming chamber according to a movement path planning of a control system of the 3D printer. A liquid supply device is provided outside the sealed forming chamber. The liquid supply device contains a gel-like reactant. The nozzle is a liquid nozzle. The liquid nozzle communicates with the liquid supply device through a following conduit. Through the phenomenon of solid deposition produced by chemical reaction between gel-like reactant and powder substance, following the digital model of the required part, and according to the processed movement path, the liquid nozzle is controlled to move in a selected area and continuously ejects gel-like reactant to have chemical deposition reaction with base powder substance. After layer-by-layer cumulative stacking with existing 3D printing additive manufacturing equipment, and after solidification, the entire part is finally formed.
A 3D printer based on liquid-solid chemical reaction deposition, comprising a sealed forming chamber (8), a powder container (14), a forming container (16), a powder spreading mechanism, and a three-axis linkage mechanism in the sealed forming chamber (8);
