Abstract
Manufacture of a 3D object by a printing method that enables the use of several reactive materials sequentially. A laser-enhanced jetting-based 3D printer forms successive layers of reactive compositions on one another and the first and subsequent layers are allowed to crosslink between the printings to ultimately form the 3D object. Additional reactive compositions may be printed prior to the crosslinking. The crosslinking may be effected by heating, with or without a catalyst, and post printing curing may be employed after the 3D object is formed.
