The invention discloses a method for manufacturing an iron-based amorphous sensor probe by laser melting three-dimensional shaping. The method comprises a step of preparing an alloy ingot and making amother alloy ingot into amorphous powder by using a gas atomization technique, a step of drawing a corresponding stereogram according to a sensor probe by using CAD software to obtain a CAD model, astep of starting a metal 3D printer, a step of hanging the amorphous powder as a consumable in a material bar, a step of performing platform leveling on the metal 3D printer, a step of slicing and generating an executable file by using slicing software, a step of starting printing through the metal 3D printer, and a step of shoveling the model by using a shovel to obtain the iron-based amorphous sensor probe. The method plays an important role in enriching the theory of magnetic monitoring and early warning of mine support, improving the safety of production in the coal mining industry and promoting the application of an iron-based amorphous alloy material and has a great theoretical value and potential economic benefit.
