The three-dimensional printer of fusion technology is used to be melted simultaneously to plastics as material and mostly by single nozzle using prefabricated plastic cord
Extrusion, completes the shaping of workpiece, generally, a kind of material or a kind of color can only be used for single model.
To print colors or the Single-issue of material, existing three-dimensional printer also has some improvement projects.
The first improvement project is to be fixed on using multiple hot junctions in three-dimensional printer movable platform, defeated using a variety of wire rods
Enter so as to realize multi-color printing, because multiple hot junctions are fixed in three-dimensional printer movable platform parallel, distance between nozzle be present,
This distance needs accurate measure and is corrected in software, otherwise can bring colour superimposition during multi-color printing.More
It is multiple to be arranged on conplane shower nozzle due to alignment error in nozzle system, there is not probability in the shower nozzle of work and print
Model produce and scratch, may damage model and shower nozzle when serious.In three-dimensional printer in use, not inside the shower nozzle of work
The plastics of thawing may be still suffered from, bring the spill and leakage of plastics, contamination model.Importantly, this scheme can not be realized very
Color three dimension printing in positive meaning.The color of printing is still limited by the wire color of input.
Second of improvement project is using the hot junction of customization, is directly inputted to using a variety of consumptive materials in shower nozzle and finally used
One shower nozzle extrusion, realize the colour mixture of a variety of different consumptive materials.This programme must insert the consumption of three kinds of colors simultaneously when in use
Material, otherwise it can cause to block at trunnion due to melting the backflow of consumptive material.Due to the three-dimensional printer using fusion sediment technology
In normal work in order to avoid consumptive material spill and leakage contamination model, it is necessary to shower nozzle not extruded material when to consumptive material carry out pumpback, should
Operation can be performed largely in the shaping of a model, possess the geometric form of complexity yet with the customization hot junction of this programme
Shape, resistance is increased, so as to increase required extrusion dynamics and weaken the validity of consumptive material high speed pumpback, easily caused
Consumptive material remains, and weakens the beneficial effect that pumpback originally can be brought, at the same in design in use, pumpback set it is improper easily bring it is stifled
Plug.In addition in nozzle carry out colour mixture when, because colour mixture chamber is small, easily occur colour mixture it is uneven and cause extrusion color can not
Control, that is to say, that although the effect of colour can be exported, color can not be controlled accurately.Therefore, the program is inconvenient for use, easily stifled
Plug, unstable, the uncontrollable drawback of color limit it and applied in production.

Follower in example one is similar, including material feeding seat 71, feeding driving wheel, feeding driven pulley and feeding motor 7, feeding motor 7
Output shaft passes through material feeding seat, and feeding driving wheel can be directly installed on the output shaft of feeding motor 7, and feeding motor 7 drives and sent
Expect driving wheel, feeding driven pulley is rotatably connected on material feeding seat, and feeding gap is formed between feeding driving wheel and feeding driven pulley,
Stock support 71 is provided with feeding mouth and feeding port, and the discharging direction of the feedstock direction of feeding mouth, feeding gap and feeding port exists
On same straight line.Due to directly using wire consumptive material 9, therefore feeding port can be connected directly with hot melt chamber 4.
In above-described embodiment, feeding assembly sets four sets, can increase and decrease the number of feeding assembly in actual product as needed
Amount, and can also be needed to select the tricks of feeding assembly specific works according to colour mixture.Because different feeding assemblies can be single
Solely control, therefore the feed speed of the consumptive material of different colours can be controlled to mix different color of objects, according to different ratios
Example, which can mix, obtains nearly all color.
In addition to above preferred embodiment, the utility model also has other embodiments, and those skilled in the art can root
It is variously modified and deforms according to the utility model, without departing from spirit of the present utility model, the utility model all should be belonged to
Scope as defined in the claims.
