This is Micro Swiss All Metal Hotend kit for Wanhao Duplicator 6. This upgrade includes a modified thermal barrier tube and modified nozzle with modified cooling block. Thermal barrier tube is made from 2 different materials. The lower thermal break is made from stainless steel, and the less warm upper part is made from aluminum. Stainless steel used to be used for thermal break because it offers low thermal conductivity, and aluminum used to be used for the upper portion because it has a lot better thermal conductivity, to carry away any heat from the filament. All metal hotend will allow you to print at much higher temperature then conceivable with original PTFE lined one. Another benefit of an all metal hotend design is more consistent melt chamber keep watch over. Throughout slow extrusion rate, in PTFE lined hotend, transition zone from solid to molten plastic has a tendency to creep upward creating more stringy prints. With all metal design a transition zone is all the time constant, being located right at the heat break. With fast extrusion rate, PTFE tube doesn’t have enough thermal conductivity to properly melt the entire plastic coming out. On original extruders that limitation happens around 60 mm/s, depending on nozzle size. All metal hotend solves this problem, plastic is surrounded by thermally conductive nozzle all over its length.
