welcome to my store Description 1.J head hotend 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. Cartridge heater Materail: Stainless Steel, PVC, Nylon Voltage: 12V Power: 30w Wire Length :1m Heater size: 6 x 15mm(D*L) 3.Thermistor MF58 B-value:3950K±3% Resistance:100Kohm±1% Thermal time constant in air:≤7Sec Operating temperature:-40℃ to +300℃ Dissipation constant in air:2.1mW/℃ 2.Nozzle drill cleaner These extruder nozzle drill cleaners are powerful tools that any 3D printer owner must have. As blocks happen a lot during the printing, extruder nozzles must be cleaned from time to time to ensure flowing printing and you will find it difficult to get access to the inner of the nozzle. These drill cleaners are here to help you. The drills are made of Tungsten steel, hard and thin enough to get into the nozzle and extract the blocked filament. There are 4 types of drills of 0.3mm, 0.35mm, 0.4mm and 0.5mm suitable for nozzles of 0.3mm to 0.5mm. Please note that the color of the rubber band on the drill cleaner is random. With these precision drill bits, you will certainly extend the life of your nozzle keep producing better models. 3.MK2A heatbed New high quality Heatbed MK2a PCB for Reprap Mendel and similar machines.
