This invention relates to a filament guide and nozzle replacement method which includes a fused deposition modeling 3D printer extruder having a filament feeding mechanism, a heating block unit, a motor configured to operate the feeding mechanism, and a detachable integrated filament guide and nozzle unit module. The method comprises the steps of detaching the detachable integrated filament guide and nozzle unit module from the heating block unit to prevent disassembling the heating block unit; disconnecting the detachable integrated filament guide and nozzle unit module from the filament feeding mechanism; connecting another detachable integrated filament guide and nozzle unit module to the filament feeding mechanism; and attaching the other detachable integrated filament guide and nozzle unit module to the block unit. |
