Abstract
The present disclosure relates to a binding agent for printing a 3D green body object. The binding agent includes from about 0.3 wt % to about 3 wt % multi-functional carboxylic acid having a weight average molecular weight range from about 100 MW to about 1,000 MW, from about 2 wt % to about 20 wt % a (meth)acrylic latex binder, from about 10 wt % to about 40 wt % solvent package including from about 3 wt % to about 40 wt % of a coalescing solvent, and from about 40 wt % to about 88 wt % water. The weight percentage ranges are based on total content of the binding agent.
