The dual-extrusion Ultimaker 3D printers, the Ultimaker 3, Ultimaker S5, and Ultimaker S3, utilize silicone nozzle covers across the bottom of the tool head which protects the articulating hotends, helps keep hotend temperatures stable, and covers the bottom from filament backflow. Over time, these silicone covers will wear out and need to be replaced, so additional covers are now available! Sold as a pack of 5 silicone nozzle covers
Over time, the silicone nozzle cover on your Ultimaker S5 or Ultimaker 3 3D printer will undergo normal wear and need to be replaced. This is an important regular maintenance task that will protect you and your Ultimaker 3D printer. The function of the silicone nozzle cover is to contain the heat of your 3D printer's hotends so that temperatures remain steady for optimal 3D printing filament flow and smooth 3D print results. Additionally, the silicone nozzle covers contribute to clean prints and minimal maintenance by helping to protect the hotends against any potential filament backflow.
