Xcalibur Replacement Barrel & Screw


SKU: RBSXCAL Category:


It’s common to be extruding different types of polymers in rotation – in which case you’ll need a clean barrel each time to ensure the resulting filament is pure and of the best quality. The best way to do this is to rotate barrel & screws between sessions.

Xcalibur Screw


  • 300mm long (400mm total), with a gradient of 130mm to 200mm, 5mm channel depth and a 23° pitch.
  • Three-stage screw increases the barrel pressure as the material mixes and passes along the length.
  • Incredibly hard-wearing and robust, making it ideal for extruding even the most abrasive materials such as carbon fibre/metal composites.
  • Rear assembly uses a deep groove thrust bearing to negate any backward pressure from the screw
