ITEM NAME:Slice Engineering Hot Block For Description: These socks will keep your nozzle clean and free of burnt on blackened plastic. They don’t just keep the nozzle clean, but also keep heat inside the , and off the print. Heat-resistant, non-stick silicone material: That will repel build-up of molten plastic, helps with sticky materials like Co-Polyesters and filled materials that like to build up on nozzles. A huge boost in temperature stability: Particularly if you use high airflow cooling around the nozzle to cool the print, the additional cooling combined with reduced radiation of heat from the block and nozzle to the print really boost the ability to print great overhangs and bridges, all while keeping the temperature extremely stable. Heat Insulator: The sock also acts as an insulator for the print head, it will reduce heat up time and help maintain a constant temperature during printing. Specification: Material: Silicone Size: 40x30x30mm Item Type: Mosquito Silicone socks Function: Heated Block Package Includes: 1 piece of mosquito silicone socks Note: Since silcone is non-stick, your print head will remain clean and it prevents filament from sticking to the heater block or nozzle.
