Abstract

A method for indirect additive manufacturing of an object, the method comprising: (i) separately feeding a powder from which said object is to be manufactured and either a difunctional curable monomer according to Formula (I) or an adhesive polymer binder into an additive manufacturing device; (ii) dispensing selectively positioned droplets of said difunctional curable monomer or adhesive polymer binder, from a printhead of said additive manufacturing device, into a bed of said powder to bind particles of said powder with said difunctional curable monomer or adhesive polymer binder to produce a curable preform having a shape of the object to be manufactured; and, in the case of the difunctional curable monomer, (iii) curing said curable preform to form a crosslinked object.
