Take the most frequently used Method of printing in market, its device structure is simple, cheap, is most commonly seen 3D printing equipment.Conventional
Adopting chemical polymerization thing 3D printing moulding material, including ABS, PLA, PC, PVA, nylon etc. more.Physics due to chemical polymerization thing
Characteristic is limited, and plastics 3D printing part usually cannot be directly as machine components or functional device.
Add nanometer conductive material, such as ultra-fine carbon dust, Nano metal powder, CNT（MWNTs) and Graphene etc., protecting
Significantly improve wearability, hardness and the heat stability of thermoplastic resin in the case that card 3D printing quality is unaffected, have simultaneously
The functions such as standby antistatic, electromagnetic shielding and conduction.Abroad, U.S.'s 3D printing technique company Graphene 3D Lab develops
A kind of Graphene/PLA conduction consumptive material, its specific insulation is 1 Ω cm, diameter 1.75 mm.The Functionalize of the U.S.
Company has manufactured a kind of CNT/PLA conduction consumptive material, and its specific insulation is 0.75 Ω cm, and diameter has 1.75 mm and 3
Two kinds of mm.America Instrument company also provides for a kind of conduction ABS consumptive material, and diameter is divided into 1.75 mm and two kinds of 3 mm.
Domestic have not yet to see conductive consumable product.
Because the addition of conductive nano agent needed for the conductive printing consumables of preparation is often larger, material can be made to become fragile, extend
Property be deteriorated, thus affecting production and the use of conductive 3D printing consumptive material.At present, there is not yet composite material conductive characteristic can be taken into account
With mechanical property solution.
