The invention discloses an additive manufacturing material and a blade additive manufacturing technique using the same. The additive manufacturing material is formed by mixing iron-based self-fluxing alloy powder and titanium carbide powder in proportion. The mass percent of the iron-based self-fluxing alloy powder is 40-60%, and the mass percent of the titanium carbide powder is 60-40%. The blade additive manufacturing technique using the additive manufacturing material comprises the following technological steps that the mixed powder is ground, drying is conducted, a blade is subjected to polishing and rust removal, oil dirt is cleaned away, coaxial powder feeding is conducted, and lasers illuminate the blade to form a reinforcing layer. The additive manufacturing material and the blade additive manufacturing technique using the same have the advantages that the thickness of the reinforcing layer made through additive manufacturing is uniform, the surface quality is excellent, the structures are compact and uniform, the hardness is high, the abrasion resistance is high, and defects such as pores and cracks are avoided; the hardness of a cutting edge can reach HV 1000 or over, the abrasion resistance of the additive manufacturing material is 3-4 times that of a matrix, and the service life of the blade is 10 times or over that of a traditional tool; the import volume of high-end steel can be reduced, the manufacturing cost of high-end tools is reduced, and the market competitiveness of the high-end tools is improved.
