Abstract
Objects produced by conventional three-dimensional printing methods are often incompletely consolidated and are not easily repaired. Printing compositions to address this issue can include a solidifiable matrix and a microwave absorber dispersed in the solidifiable matrix. The microwave absorber can be a plurality of carbon nanostructures containing a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another. Methods for processing a three-dimensional printed object can include: providing a three-dimensional printed object formed from a printing composition containing a solidifiable matrix and a microwave absorber dispersed in the solidifiable matrix, and applying a focused input of microwave radiation to the printed object at one or more locations. Applying the microwave radiation heats the microwave absorber at the one or more locations and promotes consolidation of the printing composition within the printed object.
