All Metal Hotend with SLOTTED Cooling Block for Duplicator 6

This is Micro Swiss All Metal Hotend kit for Wanhao Duplicator 6 with the following improvements: Slotted Clamping system No set screw to ding and damage thermal tube Significantly better heat transfer (this is a big one!!!) Easier disassemble and adjustments Precise control on bore diameter Micro Swiss All Metal Hotend Kit Features: 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 hotend will let you print at much higher temperature than possible with the original PTFE lined one. Another benefit of an all metal hotend design is more consistent
