Abstract: Methods of making multilayer systems comprising a sealant layer by extruding a coreactive sealant composition are disclosed. The methods can be used to fabricate multilayer systems in which individual layers have different cured properties. Individual layers can also have an inhomogeneous concentration of one or more constituents within a layer. The multilayer systems can be made using three-dimensional printing that facilitate the use of a wide range of coreactive compositions.
