Detailed description of the invention
By particular specific embodiment, presently filed embodiment being described below, those skilled in the art can be by this explanation Content disclosed by book understands other advantages and effect of the application easily.
Refer to Fig. 1 to Fig. 5.It should be clear that structure depicted in this specification institute accompanying drawings, ratio, size etc., the most only in order to Coordinating the content disclosed in specification, understand for those skilled in the art and read, being not limited to the application can be real The qualifications executed, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the tune of size Whole, under not affecting effect that the application can be generated by and the purpose that can reach, all should still fall in skill disclosed herein In the range of art content obtains and can contain.Meanwhile, in this specification cited as " on ", D score, "left", "right", " middle " and The term of " one " etc., is merely convenient to understanding of narration, and is not used to limit the enforceable scope of the application, its relativeness It is altered or modified, is changing under technology contents without essence, when being also considered as the enforceable category of the application.
Existing, in order to prevent the oxidation of metal dust during laser sintered metal dust in 3D print procedure, it may be desirable to The inert gas such as nitrogen, argon gas it is filled with in the cavity of printing objects, relatively costly.The application provides a kind of 3D printer, this 3D The cavity of printer is vacuum environment, to replace the existing technical scheme being filled with inert gas in cavity, can not only keep away Exempt from printed material at high temperature to aoxidize, it is also possible to reduce cost.
Referring to Fig. 1, the 3D printer 1 of the application is internally provided with the cavity 101 of printing objects, and a vavuum pump 102 sets It is placed in described 3D printer 1, and connects with described cavity 101, for taking the gas in described cavity 101 away to make described cavity Vacuum environment is formed in 101.The quantity of described vavuum pump 102, position, and with the connected mode of described 3D printer 1 at this Application does not limits, is not developed in details at this.
Particularly, apply this 3D printer can also directly print the vacuum solid of hollow, thus avoid printing Go out after object again by its evacuated complicated technology.For example, general vacuum cup needs through shell processing stream Big and small tens steps such as journey, inner casing work flow, shell inner casing assemble flow complete, and its purpose is that to be produced Excellent vacuum layer, thus reach the effect of heat-insulation and heat-preservation.It should be noted that utilize the 3D printer of the application to produce Vacuum cup, owing to being one printing-forming under vacuum conditions, so without considering its bubble-tight technological problems, more Add without technological problemses such as the gases in consideration its vacuum layer of extraction, significantly avoid loaded down with trivial details making step, thus reach Improve the purpose of production efficiency.Printing step is referred to: first, utilizes the modelings such as Maya, Solidworks, 3DMax, ZB soft Part sets up the three-dimensional stereo model of the vacuum cup of design；Then, successively printed by the 3D printer of the application Arrive.
It addition, the application also provides for multiple solid, the inside of described solid is hollow cavity, the inside of described hollow cavity For vacuum environment.It should be noted that described solid can be utilize the materials such as plastics, resin, metal to complete after again Extract air therein and obtain, it is preferred that directly printed by the 3D printer that above-mentioned cavity is vacuum environment and obtain.Described The shape of solid can be that spheroid, spheroid, polyhedron, centrum etc. are variously-shaped, the most such as: spheroid, cube, on four sides Bodies etc., it is preferred that for the three-dimensional shape that cube, tetrahedron etc. are made up of plane, arc is elected on its each surface respectively as Face, so that the most circumscribed contacting with other solids when, i.e. contact area minimizes.Contact area reaches Little, advantageously reduce the transmission of heat.
In one embodiment, described solid is no longer above-mentioned single solid, but by many sub-solids and use Assembly in the connector composition connecting the plurality of sub-solid.It should be noted that the concept of this lining solid is For the concept of assembly, the technical characteristic of sub-solid it is of course possible to the technical characteristic phase of above-mentioned single solid With.
Referring to Fig. 2 to Fig. 4, in one embodiment, described assembly 2 and 2 ' including: non-touching N number of 1/N geometry Body, described connector is preferably solid sphere, is positioned at the center of described assembly.In fig. 2,1/N solid be 1/8 hollow very Empty spheroid 201, described assembly 2 is formed " big spherosome " by 8 1/8 hollow vacuum spheroids 201 and solid sphere.At figure In 4,1/N solid is 1/8 hollow vacuum cube 202, described assembly 2 ' be by 8 1/8 hollow vacuum cubes 202 and " the big cube " of solid sphere composition.Particularly, as shown in Figure 3 and Figure 5, contacting with each other to reduce by each sub-solid The heat-conducting effect of Shi Fasheng, is mutually non-touching between sub-solid with sub-solid, and the contact point i.e. volume of connector is little Volume in each described sub-solid.The volume of connector is the least, and the distance between sub-solid is the least, more desirably prevents heat The conduction of amount.
Accepting above-mentioned, the solid of the application can use as insulation filler, and its quantity can be one Or multiple, its type can be the combination of same shape, can also be difform combination, and concrete selection can basis The shape of thing to be filled determines.Such as, as shown in Figure 6, thing to be filled is the interlayer 6 of thermos cup.Traditional thermos cup interlayer 6 Being intended to carry out vacuumizing process, complex process, cost are high.Present the application replaces, by the insulation of the application Filler, such as, the described assembly 2 that multiple diameters are less is poured in this interlayer 6, due to the inside of assembly 2 each described For vacuum, so the interlayer 6 after Tian Chonging just can reach the effect of vacuum layer, operation is very easy, and production efficiency can be significantly Promote, and this insulation filler can also recycle, not only environmental protection, advantageously in reducing cost.
In addition, the application provides multiple cool-bag, such as: incubator, thermos cup, incubation canteen etc., Yi Jiyi Plant 3D printer.The chamber wall of described cool-bag, described 3D printer are double-deck for the cavity wall of the cavity of printing objects Structure, is filled with insulation filler as above in the interlayer that described double-decker is constituted, thus reaches heat insulation guarantor The effect of temperature.
In sum, the 3D printer of the application, solid and insulation filler, there is reduction cost, be easy to life The multiple advantages such as product, effectively overcome various shortcoming of the prior art and have high industrial utilization.
The principle of above-described embodiment only illustrative the application and effect thereof, not for limiting the application.Any ripe Know the personage of this technology all can without prejudice to spirit herein and under the scope of, above-described embodiment is modified or changes.Cause This, have usually intellectual such as complete with institute under technological thought without departing from spirit disclosed herein in art All equivalences become are modified or change, and must be contained by claims hereof.
