| description | A filament for use in forming a support structure in fused filament fabrication i an amorphous, thermoplastic resin further comprising Bisphenol Isophorone carbonate units and Bisphenol A carbonate units, wherein the Bisphenol Isophorone carbonate units, are 30 to 50 mole percent of the total of Bisphenol A carbonate units, and Bisphenol Isophorone carbonate units in the resin, and wherein the resin has a Tg from 165°C to 200°C.The composition used to form the support filament exhibits a desirable combination of filament formability, printability, lack of significant oozing from the printer nozzle and good ease of mechanical separation from the build material at room temperature after printing. |
