Notes:
A novel variant of the three-dimensional printing technique has been developed and usedto manufacture NiTi parts. Instead of metal powder the process uses granules, which consist of amixture of metal powder and organic binder. These granules are spread on a working table. Then asolvent is dispensed with a printer head to consolidate a selected area of the granule bed and thetable is moved down. The "solvent on granule" printing process is repeated until a threedimensionalgreen body is obtained. The green part is finally debinded and sintered to obtain adense and fully metallic part. NiTi parts have been successfully produced by this technique withdensities of about 95% of the theoretical density. Detailed information on the microstructure hasbeen obtained by X ray diffraction. Sintered parts exhibit shape memory effect, which has beenmeasured during thermal cycling under tensile stress
