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 oxygen-deprivation additive in an amount of up to 25 wt. %, up to 15 wt. %, or up to 10 wt. % based on the total weight of the composition. The oxygen-deprivation additive comprises at least one of (a) an organophosphorus component, (b) a heptazine or melamine-derived component, and (c) a polymeric organobromine component.

Abstract: Compositions for additive manufacturing applications are described herein which, in some embodiments, provide improved printing properties. In some embodiments, a composition comprises a primary build material in an amount of 10-99.9 wt. % and an asphaltite additive in an amount of up to 6 wt. %, based on the total weight of the composition. In some cases, the asphaltite additive comprises a solid hydrocarbon-based mineral or a solid organic material formed primarily from hydrocarbons and found in an oil-bearing sedimentary basin, such as gilsonite.

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 intumescent additive in an amount of up to 30 wt. %, based on the total weight of the composition. The intumescent additive comprises a phosphinate component and at least one of (a) a heptazine or melamine-derived component, and (b) a proton donor component.
