Description
Technical field
The present invention relates to 3D printing technique field, and in particular to a kind of colour 3D printer nozzle.
Background technology
3D printing, is one kind of rapid shaping technique, it be based on digital model file, with powdery metal or
Plastics etc. can jointing material, come the technology of constructed object by way of successively printing.According to its molding mode and material can be used
Difference can be divided into selective laser sintering (SLS), fused glass pellet technology (FDM), stereolithography technology (SLA) and
Layered manufacturing technology (LOM), wherein fused glass pellet technology (FDM) have flexible and changeable, and engineering property is good, safeguard it is simple,
Cost is low to wait remarkable advantage, therefore the technological development is extremely rapid, and FDM technology is widely used in the whole world at present.
The material of FDM techniques is usually thermoplastic, and such as wax, ABS, PC, nylon are fed with filiform, and material is in nozzle
Interior heated fusing, nozzle is moved along part section profile and filling track, while the material of fusing is extruded, and material is solid rapidly
Change, and bonded with the material of surrounding.When if desired printing using powder or granular material, then often need to redesign cartridge nozzle
Put and integral replacing, so there are the shortcomings that the design cycle is long, cost is higher, and nozzle integral replacing is time-consuming and laborious, extremely not
Just.For FDM technology, although existing more nozzle types can print colored consumptive materials to a certain extent, each spray
Respectively there are the PLA or ABS plastic of a kind of color in head, plastics are before nozzle is extruded and the not up to mixing of real meaning, therefore beat
It is after print nor really colored, and multi-nozzle 3D printer is expensive, it is complicated, it is unsuitable for being widely popularized.
The content of the invention
Present invention seek to address that existing 3D printer be difficult to realize single nozzle colour print, cannot compatible different shape consumption
The technical problem of material.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：

The internal diameter size of outside diameter and the nozzle match, be connected with power set on the top of the screw rod；Squeezed in the mixing
Go out chamber outer wall and be equipped with heating unit；
The feed pieces are at least two groups, are removably mounted equidistant on the side wall circumference of the housing,
Be equipped with feed cavity in the feed pieces, the upper end of the feed cavity is connected with exterior feed mechanism, lower end with it is described
Mixing extruder chamber is connected.
Preferably, the feed pieces are conduit type feed pieces, its feed cavity is the conduit to match with Filamentous consumptive material
Type.
Preferably, the feed pieces are funnel type feed pieces, its feed cavity be for powder or graininess consumptive material into
The funnel type of material.
Preferably, material level sensor is equipped with the charging cavity wall of the funnel type feed pieces.
Preferably, the feed pieces and the side wall of the housing are installed in 30~60 degree of overturning angles.
Preferably, the feed pieces are four groups, and the side wall circumference in the housing is removably mounted equidistant
On, the feed pieces and the side wall of the housing are installed in 45 degree of overturning angles.
Preferably, four groups of feed pieces correspond respectively to the charging of red, green, blue, black four kinds of color consumptive materials.
Preferably, the power set on the screw rod top are stepper motor.
The beneficial effects of the present invention are：
1. setting multiple feed pieces on nozzle, each feed pieces correspond to the charging of different colours consumptive material, Duo Zhongyan
The consumptive material of color can carry out mixing toning in mixing extruder chamber, really realize the colour print of single nozzle, overcome existing
The technical problem that single nozzle can only carry out the printing of solid color in technology, colour print need to be using multiple nozzles to realize.
2. feed pieces are designed as two kinds of conduit type and funnel type, Filamentous consumptive material and powder, granular consumptive material are respectively used to
Charging, using different consumptive materials when, only feed pieces need to be replaced, without redesigning and replacing whole spray
Head so that single nozzle can compatible a variety of consumptive materials, reduce the cost of 3D printing, use and to replace feed pieces more square
Just, fast.
