At present paper the existence of the shape memory effect in the porous titanium nickelide (NiTi intermetallic phase, named as nitinol), which was synthesized by the Selective Laser Sintering/Melting (SLS/M) processes are described. In order to characterize the particularities of phase-transformation behavior the scanning electron microscopy with EDX and X-ray analysis were used. The phase structure content, thermal dependences of electrical resistivity are presented depends of laser influence parameters. At porous nitinol the electrical resistivity peaks and humps are corresponded to the start and finish temperatures of the transition from the austenite to martensite phase and back and should be used for Shape Memory Effect (SME) estimation. Advantages and disadvantages perspectives of bio - MEMS fabrication from this porous material are discussed.
