Bottom level position, minitype motor driving drive idler wheel rotation, and driving idler wheel drives driven roller rotation by the connection of flexible strand
Turn, flexible strand passes through left charging basket and dips melt/solution, and conductive receiver plate reaches predetermined position, and thimble passes through the mobile sliding block of thimble
It is moved to the lateral position of setting, thimble moves down, and flexible strand ejects protrusion, the colored melt that protrusion dips/molten by thimble
Liquid forms jet stream, jet stream cooling and solidifying or solvent volatilization solidification between conductive receiver plate and thimble under the action of high voltage electric field,
It deposits and on the molded solid that is bonded on conductive receiver plate, it is remaining in flexible strand during flexible strand continuous operation
Melt/solution is extruded under the turning effort of left squeezing roller and right squeezing roller after entering right charging basket and concentrates on right material
In bucket, the print procedure of other setpoint colors is same as described above, forms the colored jet stream deposition of the point of multiple setpoint colors
Combination, the purpose of printing predetermined plane is realized, then by the movement from up to down of lifting slider control conductive receiver plate, by face
Printing；Thimble is lifted up, and flexible strand is since elasticity restores linear state, and protrusion disappears, and jet stream disappears, and stops printing, repeatedly
It repeats the above process, finally printing obtains the product of setpoint color required precision；When melt/solution volume in right charging basket is super
When crossing setting value, micromotor rotates round about, and driving idler wheel reversely rotates, and driven roller is reversed under flexible strand drive
Rotation, flexible strand dip melt/solution from right charging basket and are printed, and remaining melt/solution is in left charging basket in flexible strand
It is trapped；Left charging basket and right charging basket can individually feed.
Colour 3D printing device of the present invention is moved by the transverse shifting of control thimble and the front and back of conductive receiver plate
The deposition position for carrying out controlled level direction jet stream is moved, the deposition process of a setpoint color jet stream in plane is carried out, by multiple
Independent deposition process realizes the deposition of different composition color jet streams on two-dimensional surface, and then realizes that the entirety of setting two-dimensional surface is beaten
