1. A method of fabricating a three-dimensional object, comprising:

  • a) depositing a particulate composition in a defined region, said particulate composition including;

    i) from 70 wt % to 99.9 wt % of polymeric particulates, andii) from 0.1 wt % to 10 wt % of a polymerization initiator;

    b) jetting a liquid phase binder onto a predetermined area of the particulate composition to form a layer of polymeric cement in the predetermined area, said liquid phase binder including;

    i) from 70 wt % to 90 wt % of polymerizable monomers, andii) from 0.1 wt % to 10 wt % of a polymerization accelerator;

    c) repeating steps a) and b) such that multiple layers of polymeric cement are formed that are bound to one another.
