Description
Technical field
The utility model relates to three-dimensional printing technology field, particularly a kind of three-dimensional printer.
Background technology
3 D-printing prints also known as 3D, belongs to the one of RP technique, and it is a kind of based on mathematical model file, uses moulding material, is carried out the technology of constructed object by the mode of successively stacking accumulation.Past 3 D-printing is often used in modeling in the field such as Making mold, industrial design, existing just gradually for the direct manufacture of some products.First the process of 3 D-printing is by CAD (CAD) or the modeling of computer animation modeling software, again the threedimensional model " subregion " built up is become cross section successively, obtain machining path according to analysis cross section information again, thus instruct printer successively to print.
As the Typical Representative of three-dimensional printing technology, shaping (the i.e. FusedDepositionModeling of FDM, fused glass pellet) be a kind of accumulation by melted material superposition and form the technique of three-dimensional entity model, general employing is curing molding method successively, make the resin after printing become solid layer by layer, thus produce three-dimensional contouring product.Common moulding material comprises ABS, PLA etc.It is generally the moulding material by the printhead upper end input wire toward three-dimensional printer, the moulding material of wire is through the high-temperature fusion in printhead, the filamentary material of about about 0.1 ~ 0.2mm is extruded from printhead outlet, then this filamentary material according to program, be arranged on molding seat regularly, thus realize three-dimensionally shaped.
Along with the progress and development of society, the fast-developing every field also having progressed into social life of three-dimensional printing technology, a three-dimensional printer can adopt multiple material to print, such as, use the three-dimensional printer of ABS material, material such as the materials such as nylon that some also can be used close with ABS print.In addition, the material of multiple color can be adopted when three-dimensional printer prints directly to print colored 3D solid.
In use, moulding material generally can be contained in forming material magazine, and moulding material box is arranged on the magazine installing rack of three-dimensional printer, is provided as shaped material by discharging opening to 3 D-printing head.From printhead filamentary material out, be approximately the high temperature of 200 degrees centigrade time in printhead, when spraying from printhead, the temperature of filamentary material is reduced to consistent with environment temperature.When filamentary material is arranged on molding seat, because the temperature of filamentary material and the temperature of molding seat there are differences, filamentary material is made not to be attached on molding seat well.Print the filamentary material from printhead high temperature fused state out when just starting, may local temperature be there is too high, cause existence can not fracture of wire well, occur the situation of wire drawing.In follow-up print procedure, owing to there is the impact of collodion silk internal and external temperature difference, threedimensional model can not entirely in layer be stacked up, and easily cause the threedimensional model finally printed to there is the situation such as layering, distortion, molding effect is stable not.
In prior art, have people to arrange the seal casinghousing surrounding type body in the surrounding of 3 D-printing main body, seal casinghousing adopts dismountable structure, and seal casinghousing arranges heat-insulation layer, thus realizes the heat insulation function in print procedure.But this technical scheme still existing defects, namely the size of seal casinghousing needs customization in advance.If the height of seal casinghousing self is less than the height of object to be printed, object to be printed exceeds the surrounding of the part of seal casinghousing owing to not having the insulation effect of seal casinghousing, still there will be the phenomenon such as layering, distortion, affects molding effect.If the height of the seal casinghousing self of customization is very high, or freely assembled, although its heat insulation function can be ensured, there is the problem that cost is higher, splicing is inconvenient.
