Copper-based shape memory alloys Cu-13.5Al-4Ni-0.5Ti with high relative density, high strength and high hardness are fabricated by selective laser melting (SLM). The microstructures are characterized and the tensile properties at room temperature and 300 ℃ are evaluated, respectively. The results show that the maximum relative density of 99.5% is obtained when the laser input energy is 110 J·mm -3. The lath martensite extending in parallel in the microstructure of the sample grows across the melting tracks and the average grain size is about 43 μm, The grain size of the SLM-fabricated sample is smaller than that of the casting sample. The average tensile strength and percentage elongation after fracture of the SLM-fabricated sample are (541±26) MPa and (7.63±0.39)% at room temperature, respectively, and the tensile strength is increased to (611±9) MPa at 300 ℃, and the percentage elongation after fracture is increased to (10.78±1.87)%. The SLM-fabricated alloy shows a good application potential in the high temperature fields.
