Abstract: Compositions for additive manufacturing applications are described herein which, in some embodiments, impart flame resistant and/or flame retardant properties to articles printed or formed from the compositions. The compositions may also impart desirable mechanical properties to the articles. In some embodiments, a composition comprises a sinterable powder or a thermoplastic polymer in an amount of 10-99 wt. %, based on the total weight of the composition, and an expandable graphite component in an amount of up to 20 wt. %, based on the total weight of the composition. In some instances, the expandable graphite component is in its free form or encapsulated in material.
