According to the method, the printing efficiency can be greatly improved, and high application value is achieved.
Description
Technical field
The present invention relates to a kind of rapid three dimensional printing forming field, be specifically related to a kind of many shower nozzle high speed FDM model Method of printing fields.
Background technology
In recent years, along with the development of science and technology, 3D printing technique more and more receives the concern of people, 3D printing technique be known as a kind of lead third time the industrial revolution revolutionary technology.3D printing technique can be described as again and increases material manufacturing technology or RP technique, belongs to the one of advanced manufacturing technology.The general implementation process of 3D printing technique of broad sense is: first by three-dimensional modeling design software or three-dimensional reverse technology, three-dimensional modeling data needed for acquisition, the model obtained is carried out to format conversion and carries out data restore, imported in 3 D-printing software again, through 3 D-printing software hierarchy slicing treatment, obtaining the discrete synusia data message of model, by piling up shaping to the successively printing of each single layer data, thus obtaining the threedimensional model exemplar of final printing shaping.
Existing 3D printing technique mainly can be divided into: selective light curing technology (SLA), Selective Laser Sintering (SLS), molded through three-dimensional printing technology (3DP), Laminated Object Manufacturing (LOM) and melted extrusion modeling technology (FDM), wherein FDM technology due to its machine and moulding material price relatively cheap, be developed rapidly in recent years.
FDM technology, mainly adopt low melting point filamentary material as shaping raw material (as: ABS, PLA plastics, nylon etc.), utilize Electric heating that silk material is heated to molten condition, under the control instruction driving that controller sends, machine movement is coordinated to extrude melted material as required, form a layer cross section of workpiece after cooling, after one deck is shaped, shower nozzle brings Forward highly, carry out lower one deck coating, so successively pile up and form 3 D workpiece.
The technological principle of melted extrusion modeling technology determines it and can only carry out print job by single shower nozzle at one time, and the print quality of model entirety will be ensured, the wire vent aperture of shower nozzle can not be too large, to which results in but its shaping time cost is larger, it is applied widely and defines restriction.
Summary of the invention
Goal of the invention: the flying print of implementation model, promotes 3D printing effect.
Technical scheme:
1) a kind of many shower nozzle high speed FDM model Method of printings of the present invention, for the deficiency that existing FDM Method of printing shaping efficiency is low, adopt the flying print of many nozzle structures realization to model, promote printing effect.
2) for realizing flying print, the region high in the complicated required precision of model local shape needs to adopt meticulous shower nozzle to print, simple at model local shape or in regular geometric shapes region adopts thick bore shower nozzle to print, and the shower nozzle of moderate bore can be adopted to print in other region.
3) need to analyze model data file for realizing above function, specific model slice algorithm is adopted to carry out hierarchy slicing to model, according to the difference that model local fine degree requires, be cut into the synusia data that thickness differs, and as required synusia data distributed to the shower nozzle of different bore.
4) according to above Slicing Algorithm criterion, the slice of data of shower nozzle to the different-thickness of model switching different bore as required prints, and after having printed, carries out the printing of next synusia data on this basis.
5) constantly 4 steps are repeated, until complete the printing of model.
Beneficial effect:
A kind of many shower nozzles high speed FDM of the present invention model Method of printing, adopt the shower nozzle of multiple different bore, print on demand is carried out to the region that the different fineness of model requires, under the prerequisite ensureing precision, shorten the time that model prints greatly, improve the efficiency of printing, for printing, large-scale modelling effect is particularly evident.
The present invention is innovative product that is original, that have independent intellectual property right.One provided by the present invention many shower nozzle high speeds FDM model Method of printing, greatly reduces the time that model prints, improves shaping efficiency, especially for the printing of large-scale model.The method has good application prospect.

Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is further illustrated.
In 3D print procedure, first need the acquisition carrying out model, the acquisition process of model can be divided into forward to obtain and reverse acquisition, and the acquisition process of forward is generally use Three-dimensional Design Software to carry out the production process grown out of nothing; Reverse design process uses triplex scanner to scan already present model, thus obtain the data of model and carry out necessary amendment, finally obtains model data.
The model data that above two kinds of methods obtain generally all needs to transform its form, and carries out diagnosis and the reparation of model parameter, makes it meet the form input requirements of 3D print software.
For final obtained qualified model data, according to the demand of the inventive method, need to carry out the thickness such as non-section to it, the method be different from universal model etc. thickness section.Fig. 1 is the thickness slicing delamination schematic diagrames such as sphere model is non-, in sphere model 4 slicing processes, between spheroid mid portion slicing layer, graded is smaller can be cut into thick slicing layer 3, in the process of spheroid cumulative printing shaping gradually, between slicing layer, graded is obvious gradually, slicing layer can not be too thick, so this region slicing layer is thicker slicing layer 2, between the top area slicing layer of ball, graded is fairly obvious, and the section of this region is all thinly-sliced lamella 1.
The synusia data cut are sent to print control unit, and the shower nozzle that different slicing layer distributes to different bore prints by the difference of thickness by controller.The printing head of thinly-sliced lamella 1 correspondence is small-bore shower nozzle 6, and the printing head of thicker slicing layer 2 correspondence is larger caliber shower nozzle 7, and the printing head of thick slicing layer 3 correspondence is heavy caliber shower nozzle 8.Fig. 2 is the structure diagram of printer printing head 5, and heat block 9 provides a material to reach temperature needed for molten condition, it has three shower nozzles be respectively: small-bore shower nozzle 6, larger caliber shower nozzle 7 and heavy caliber shower nozzle 8.
When carrying out model and printing, printing head 5 carries out print on demand operation according to the automatically switch shower nozzle of corresponding bore of the thickness of section by the profile of current slice layer, complete after current layer prints, then with it for lower one deck printing is carried out in bottom surface, and constantly repeat this print procedure.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should be appreciated that; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by its equivalent of appending claims.
