Abstract
In one aspect, waxy build material inks are described herein which, in some embodiments, exhibit desirable print quality and associated mechanical properties for three-dimensional printing applications. A build material ink, in some embodiments, comprises 20-40 wt. % rosin component, 5-35 wt. % non-polar wax component, and 40-65 wt. % alcohol wax component comprising one or more waxes of the formula (CnH2n+1)OH wherein n is an integer from 15 to 40. In another aspect, a build material ink comprises a eutectic mixture including rosin component, a non-polar wax component, and an alcohol wax component comprising one or more waxes of the formula (CnH2n+1)OH wherein n is an integer from 15 to 40.
