Figure 1
The schematic illustrates a dual-extruder continuous fibre reinforced 3-dimensional-printing system with separate Matrix filament and Fibre filament spools feeding independent extruders mounted on a movable print head. The Matrix extruder deposits polymer matrix material while the Fibre extruder deposits reinforcing fibre material onto the print bed. A Cooling fan is positioned beside the extrusion area. Layered printed matrix layer and printed fibre layer structures are shown beneath the extruders, demonstrating alternating composite deposition. The x-axis and y-axis movement directions are indicated near the print head assembly, and vertical movement is represented by a double-headed arrow above the extruders.A schematic diagram of the Markforged® Mark Two FFF printer
