An article includes at least two contiguous layers containing a composition that includes a branched polycarbonate, optionally a linear carbonate-containing polymer, and 0 to less than 5 weight percent filler. The composition is characterized by an average mole percent branching of 0.06 to 2.4 mole percent, which is calculated as 100 times moles of branched carbonate units in the branched polycarbonate divided by the sum of moles of linear carbonate units in the branched polycarbonate and the optional linear carbonate-containing polymer. The composition is further characterized by a melt flow rate of 1 to 20 grams per 10 minutes, determined according to ASTM D1238-13 at 300°C and 1.2 kilogram load. Also described is a method of additive manufacturing utilizing the composition. |
