    摘要： A fully curable jettable composition having a viscosity less than 30 cps at a temperature within the range of 15° C.-180° C. comprising (i) at least one low viscosity reactive resin; (ii) at least one higher viscosity resin having a viscosity greater than twice that of the low viscosity resin and a functionality of greater than or equal to 2; (iii) at least one curable toughener, (iv) at least one initiator for the polymerisation of the resins, and (v) at least one stabiliser for delaying the curing of the resins of the composition. The composition can be jetted from piezo electric printing heads under the control of a computer program to form a multi-layered article, for example, a three dimensional article, in which the adjacent droplets merge and are cured homogeneously together.
