Abstract
The invention provides a gas atmosphere-type 3D (Three Dimensional) printing box. The gas atmosphere-type 3D printing box comprises a printing box, a box door, gas atmosphere tanks, an inlet control valve, an outlet control valve and a suck-back resistance device, wherein the printing box is used as a shaping space for 3D printing; the box door is peripherally sealed with sealing rubber strips, so that closure of the printing box during work is ensured; the gas atmosphere tanks are used for storing gas for use; the inlet control valve and the outlet control valve are separately arranged on an inlet pipeline and an outlet pipeline of the printing box and are sued for adjusting gas flow; the suck-back resistance device is arranged at an outlet of the outlet pipeline and is used for preventing suck-back of the gas; the multiple gas atmosphere tanks are arranged for storing the gas; and the gas can be nitrogen and argon, helium and other inert gas, and can also be oxygen, hydrogen and other reaction gas. By adopting the gas atmosphere-type 3D printing box disclosed by the invention, 3D printing can be performed under the protection of nitrogen, argon, helium and other inert gas, so that purity of forming product materials is ensured; and 3D printing can also be performed under the protection of oxygen, hydrogen and other reaction gas, so that the gas is reacted with the printing materials to generate new materials, and accordingly the range of the 3D printing materials is broadened.
Description
Technical field
The present invention relates to 3D printing device field, particularly relate to a kind of atmosphere formula 3D and print casing.
Background technology
3D printing technique, also known as increasing material manufacturing technology or 3D rapid shaping technique, originate from the eighties in 20th century, a kind of based on mathematical model file, adopt dispersed material (liquid, powder, silk, sheet, plate etc.), manufactured the technology of any complex structure by successively cumulative mode.Current 3D prints and generally carries out in atmosphere, but for some materials, as metal, is easily oxidized in atmosphere, have impact on the purity of the composition of products formed.In addition, the material that current 3D prints mainly comprises the materials such as the plastics such as ABS, PC, PA, PLA, photosensitive resin, rubber, stainless steel, titanium alloy, pottery, concrete, and current printing technique only can choose single printed material when each printing, the range of application limiting 3D printing serious like this, patent of invention (application number: the 3D printer 201410102591.3) proposing many components reaction curing materials, widened the scope of printed material to a certain extent, but it is only limitted to the material that reacts in atmosphere.
Summary of the invention
For prior art Problems existing, the present invention proposes a kind of atmosphere formula 3D and print casing, 3D printing can be carried out under different atmosphere, improve the purity of products formed material, expand 3D and print the scope that can utilize material.
In order to solve the problems of the technologies described above, technical scheme of the present invention is
Print casing, as the molding space that 3D prints, two relative side box bodies are provided with import and export pipeline;
Cabinet door, is sealably arranged on described printing casing;
Atmosphere tank, for storing gas used;
Import and export control valve, be separately positioned on described import and export pipeline, for adjusting gas flow;
Suck-back device, is placed on the exit of described outlet conduit, for preventing the suck-back of gas.
Described atmosphere tank can have multiple, stores multiple gases.
Described gas can be nitrogen and the inert gas such as argon gas, helium, also can be that oxygen, hydrogen etc. can react with the raw material in described printing casing the reacting gas generating and print material therefor.
The invention provides a kind of atmosphere formula 3D and print casing, 3D printing can be carried out under the protection of nitrogen and the inert gas such as argon gas, helium, ensure that the purity of products formed material; Also can carry out under some reacting gas such as oxygen, helium, gas and printed material react, and generate new material, thus have widened the scope of 3D printed material.

Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Embodiment
Refer to shown in Fig. 1, a kind of atmosphere formula 3D prints casing, comprising:
Print casing 1, as the molding space that 3D prints;
Cabinet door 6, surrounding sealing joint strip 7 seals, the closure of printing casing during guarantee work;
Atmosphere tank 2, for storing gas nitrogen used;
Import and export control valve 4 is separately positioned on printing casing 1 and imports and exports on pipeline 3, for adjusting gas flow;
Suck-back device 5 is placed on the exit of outlet conduit 3, for preventing the suck-back of gas.
Specific works of the present invention is as follows:
Before printing, close cabinet door 6, open the switch 8 of atmosphere tank 2, adjustment imports and exports control valve 4 to suitable nitrogen flow, and the air in casing 1 is all discharged, and makes to print casing 1 inside and is full of nitrogen, carry out 3D printing afterwards; Print in casing 1, be placed with the material of printing, can adopt existing 3D printing technique that finger is printed to required object, specifically arrange, this is not restricted; In the process printed, need the bubble effusion situation of observing in suck-back device 5, prevent the refluence of gas, after printing shaping terminates, closing switch 8, closes and imports and exports control valve 4, open cabinet door 6, takes out printing shaping product.
Described atmosphere tank has multiple, stores different gas respectively.
Above-mentioned gas can be the inert gas such as argon gas, helium, also can be that oxygen, hydrogen etc. can react with the raw material in described printing casing the reacting gas generating and print material therefor.
Above-listed detailed description is illustrating for possible embodiments of the present invention, and this embodiment is also not used to limit the scope of the claims of the present invention, and the equivalence that all the present invention of disengaging do is implemented or changed, and all should be contained in the scope of the claims of this case.
