Claims16
-26. (canceled)
A method of three-dimensional printing an object comprising:
- (a) extruding a coreactive composition, wherein,
- the coreactive composition comprises a first component comprising at least two first functional groups and a second component comprising at least two second functional groups,
- the second functional group is reactive with the first functional group;
- and
- at least one of the first functional group and the second functional group comprises a saturated functional group;
- and
- (b) building a three-dimensional printed object;
- wherein extruding comprises forming an extrusion wherein the extrusion is characterized by a cross-sectional profile having an inhomogeneous material composition.
