A pack of 3x high temperature non-stick silicone socks for the E3D Volcano and other HotEnds also using a Volcano-style heater block with thermistor cartridges. They will not properly fit the older screw-washed clamped thermistor-style Volcano heater block.
These socks will keep your heater block clean and free from burnt and blackened plastic. They don’t just keep the block clean, but also keep heat inside the HotEnd and off your print.
Made of a heat-resistant, non-stick silicone material our socks will repel build-up of molten plastic. This really helps with sticky materials like co-polyesters and filled-composite materials that like to build up on nozzles.
These socks also offer 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 heat radiation from the block to the print really boost the ability to print great overhangs and bridges, all while keeping the HotEnd temperature extremely stable.
The covers simply push onto the front of the HotEnd with no disassembly - they will be a tight fit when first pushed on cold. When hot the silicone will expand to the correct size to fit the hotend snugly. The elastic material will fit all nozzle sizes in the range from 0.4mm to 1.20mm.
These Volcano socks come in a pack of 3 because while they are durable they don’t last forever. Depending on what materials you print and how much abuse they get they eventually wear away, although this design has a much improved life expectancy than the first generation.
