description A print-head assembly (150) for effecting fused deposition modelling, comprising of a pair of extruder blocks (40a, 40b), each respectively adapted to receive a thermoplastic filament (30a, 30b), and respectively extrude the thermoplastic filament (30a, 30b) such that the thermoplastic filament material is in heat transfer communication with a thermal block (20). The thermal block (20) including a heating element (22) that serves to heat and increase the temperature of the thermal block (20) to a temperature sufficient to cause phase change of the pair of thermoplastic filaments (30a, 30b). The print-head assembly further including a pair of nozzles (10a, 10b) that are rendered in fluid communication with a respective thermoplastic filament (30a, 30b), each nozzle (10a, 10b) of the pair of nozzles (10a, 10b) differing in diameter, with the nozzle (10a, 10b) having a larger diameter being utilized for low accuracy bulk infilling operation and the nozzle (10a, 10b) having a smaller diameter being utilized for relatively accurate infilling operation.
