The invention relates to a near-infrared responsive scaffold for promoting bone defect repair, and a preparation method and application thereof. The scaffold is a polylactic acid scaffold containing Ti₃C₂Tₓ, prepared by fused deposition modeling 3D printing using polylactic acid filament containing Ti₃C₂Tₓ. The preparation steps are: S1: Add Ti₃C₂Tₓ to polylactic acid filament raw materials, mix uniformly, feed into a twin-screw extruder for granulation to obtain polylactic acid filament pellets, and dry for later use; S2: Feed the dried pellets into a drawing device, set drawing parameters for drawing, and dry to obtain polylactic acid filament containing Ti₃C₂Tₓ; S3: Use a 3D printer with the Ti₃C₂Tₓ-containing polylactic acid filament as printing material, set printing parameters for 3D printing to obtain the Ti₃C₂Tₓ/polylactic acid scaffold. The raw materials are simple, low-cost and biosafe.
