Abstract
The disclosure relates to sintering compositions that can be used in three-dimensional printing or additive manufacturing processes. The sintering compositions generally include one or more metallic iron-containing powders and a minor amount of a boron-containing powder as a sintering aid. Sintered models or products formed from the sintering compositions have substantially improved density and surface roughness values relative to models formed without the boron-containing powder.
