Micro Swiss All Metal hot end upgrade for Wanhao Duplicator 6 comes with a CNC machined slotted cooling block. The dramatically improves the heat dissipation on the cold side of the hot end which improves the performance of the hot end as well as improve print quality. The All metal hot end is a lot more durable than the PTFE hot ends and provide cleaner prints. This is a drop in replacement for the extruder on the Wanhao Duplicator 6 to improve your print performance.

Micro Swiss deliver precision that surpasses your highest expectations for custom-machined components with tolerances as low as .0002 (2/10,000) of an inch.

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 colder upper part is made from aluminum. Stainless steel was used for thermal break because it offers low thermal conductivity, and aluminum was used for the upper portion because it has a lot better thermal conductivity, to carry away any heat from the filament. All metal hot end will let you print at much higher temperature than possible with original PTFE lined one. Another benefit of an all metal hot end design is more consistent melt chamber control. During slow extrusion rate, in PTFE lined hot end, transition zone from solid to molten plastic tends to creep upward creating more stringy prints. With all metal design a transition zone is always constant, being located right at the heat break. With fast extrusion rate, PTFE tube doesn't have enough thermal conductivity to properly melt all the plastic coming out. On original extruders that limitation happens around 60 mm/s, depending on nozzle size. All metal hot end solves this problem, plastic is surrounded by thermally conductive nozzle throughout its length.
