Abstract: A three-dimensional printing formulation can include polymeric powder. The polymeric powder can include high aspect ratio composite particles including glass fibers coated with an encapsulating polymer in an amount from about 5 wt % to about 80 wt % based on a total weight of the polymeric powder, and low aspect ratio filler particles in an amount from about 20 wt % to about 95 wt % based on a total weight of the polymeric powder. The high aspect ratio composite particles can have an aspect ratio from about 7:1 to about 30:1 and the low aspect ratio filler particles can have an aspect ratio from 1:1 to less than 7:1.
