welcome to my store ge-th2009 Description Please note:This is a 0.5mm nozzle for 1.75mm filament J head hotend.If you want to change the size of it,please contact us as soon as possible. The Bowden principle The Bowden cable lets you reduce the moving mass of the extruder and thus allowing faster controlled motion, less shaking of your machine, less energy use and importantly: faster printing! Normally the mechanism that drives the filament into the hot end (where it melts) is directly on top of the extruder. This creates problems of balance and oscillations with faster motion which you can see in your printing results and hear and feel when your machine is shaking. If the filament drive mechanism is placed on a non-moving part of the 3D printer, it can be pushed into a tube. PTFE (Teflon) is useful because it is slippery: it has little friction with the plastic.This limits wear and loss of energy. The tube's other end is connected to the extruder's hot-end. The concept of using a Bowden cable as guide was suggested and pioneered by Ed Sells. The main advantages All metal enables working with Polycarbonate up to 300 degrees Celsius and with future materials that require higher working temperatures beyond those supported by plastic extruders and hot end. Tested with PLA, ABS, polycarbonate, nylon and PVA. Features The J-head is assembled with 100K NTC thermistor and Cartridge heater,NOT heat resistor.Check the following specifications for the assembled heater. Materail: Stainless Steel,PVC,Nylon Voltage: 12V Power: 30w Wire Length :1m Heater size: 6 x 15mm(D*L) To make your printing easier,a 30x30mm 12VDC cooler fan is assembled for heat dissipation. The inner diameter of the bowden feed mouth is 4mm to print with 1.75mm filament,and 6mm to print with 3mm filament.
