Summary: | There is disclosed a filament deposition modelling filament for manufacturing an object, formed from a feedstock material comprising one or more polymeric material selected from:i) a polymeric material (A) having a repeat unit of formula -O-Ph-O-Ph-CO-Ph- Iand a repeat unit of formula -O-Ph-Ph-O-Ph-CO-Ph IIwherein Ph represents a phenylene moiety; and/orii) a polymeric material (B) having a repeat unit of formula -X-Ph-(X-Ph-)nX-Ph-CO-Ph- IIIand a repeat unit of formula -X-Y-W-Ph-Z- IVwherein Ph represents a phenylene moiety; each X independently represents an oxygen or sulphur atom; n represents an integer of 1 or 2; Y is selected from a phenylene moiety, a -Ph-Ph moiety and a naphthalenyl moiety; W is a carbonyl group, an oxygen or sulphur atom, Z is selected from -X-Ph-SO2-Ph- -X-Ph-SO2-Y-SO2-Ph-and -CO-Ph-. |
