Description: Uses an extrusion head of the all-metal structure, suitable for 1.75mm supplies of equipment, pipes with the new structure. The installation of a Teflon tube that supplies a better solution in the extrusion process to heat the material issues, therefore it belongs to the latest extrusion head structure. Heating / thermocouple: 12V heating / thermocouple / thermistor. SGS heating tube with 40W, such as special needs, can reprovision thermal resistance thermistor maximum heating temperature is 280 degrees, while the thermal galvanic temperature can exceed 300 degrees. If there is no special account, default 12V, 40W heating tubes, and heat resistance. Specification: Model: i3d-002 Size(length and breadth): Approx. 11x9x7.5mm / 0.43x0.35x0.29inch Material: Metal Weight: 400g Extrusion nozzle: 0.4,0.3,0.2 optional (default 0.4mm) Probably parameters: motion shaft speed: 40mm / Nozzle flow rate: about 24cc / h Print Material: 1.75mmABS or PLA. Stepper: 42 stepper motor, Fan: cooling fan default working voltage 12V. Voltage: extrusion head heating voltage 12V, 4.8-6 ohm resistor Package Includes: 1 Piece 12V/0.4mm Single Printer Head Note: Different displays may cause the color of the item in the picture a little different from the real thing.
