Disclosed is an improved extruder head for a fused filament fabrication 3D printer. It would be beneficial with a thinner nozzle diameter and higher extrusion speed without slippage in the feeding mechanism. The proposed improved extruder head enables extrusion of thinner extruded material at a higher extrusion speed without any slippage in filament feeding mechanism, thereby allowing higher overall building speed of the 3D printer with high quality build. Higher feed-rate of the filament material is achieved by increased usable friction between pinch wheel and filament by increasing the grippable area of the filament. This is done by feeding the filament into the feeding mechanism at an angle different to the outlet angle and routing it around the pinch wheel, back supported by a plurality of support rollers, so that the filament is in frictional contact with the pinch wheel along a greater part of its circumference, thereby increasing the surface contact area between the pinch wheel and the filament. Owing to non-slippage of the filament feeder, nominal volume of extruded material is exactly the same as desired volume with high filament feeding rate. Due to compact feeding mechanism, total mass of extruder kept small enough to enable higher acceleration of the printing nozzle resulting higher printing speed. Owing to horizontal loading of the filament material, feed roll can be mounted just above the extruder for smooth filament supply and compact size of 3D printer.
