A polymer composition containing a polyoxymethylene polymer having low shrinkage characteristics and/or an expanded processing window is disclosed. The polymer composition is particularly well suited for use in three-dimensional printing systems, such as printers that use filament fusion technology. The polymer composition, for instance, can be a feed material in the form of a filament or polymeric pellets. The feed material can be placed in a printer cartridge for insertion into a three-dimensional printing system. In accordance with the present disclosure, a polyoxymethylene polymer is combined with one or more dimensional stabilizing agents for dramatically improving the processing characteristics of the polymer.
