Reaching 100%, part machinery performance is suitable with Forging Technology gained；
3) use has the laser instrument of high power density, with the laser beam processing metal that hot spot is the least so that process
Metal parts there is the highest dimensional accuracy (reaching 0.1mm) and good surface roughness (Ra 20～40 μm)；
4) the least due to laser spot diameter, therefore the laser energy density of metal bath is the highest so that use single component
Metal powder layer manufacture part and be possibly realized, and alternative metal powder layer kind is expanded the most significantly；
5) it is suitable for the workpiece of various complicated shapes, is especially suitable for inside and there is complicated abnormal shape structure (such as cavity, three dimensional network
Lattice), the complex part that cannot manufacture by traditional method；
The 3D printing device of application SLM technology is in part print procedure, and laser irradiates metal dust layer by layer, generates metal
Molten bath, metal inevitably generates a part of bulky grain oxide in fusing, process of setting, and this part bulky grain aoxidizes
Thing needs to enter cleaning system together along with protective gas, is collected by filtration.For the ease of metal dust preparation layer by layer with
Print the recovery of metal powder layer, working chamber's base plate usually can be designed to a kind of structure with big plane pit,
This structure is highly detrimental to bulky grain oxide and enters purification recovery device suction powder groove, thus by filtration, purification.If it is this kind of
Bulky grain oxide does not enter circulating purification system together along with protective gas, and remains in laser forming district, because of its thing
Reason, chemistry, material behavior are widely different with metal powder layer, if be again irradiated with a laser sintering, may result in part
Shaping failure.
Utility model content
Cannot be filtered only completely into inhaling powder groove for solving the bulky grain oxide when applying SLM technology to carry out 3D printing
The defect changed, this utility model spy provides a kind of band bulky grain oxide to reclaim the 3D printing device of guider.
The technical solution of the utility model is as follows:
A kind of band bulky grain oxide reclaims the 3D printing device of guider, including formation cylinder, is arranged in formation cylinder

Structure, wherein the step upper end of side base plate is provided with suction powder groove, and the step corner of this base plate is provided with guide part；Other one
It is provided with inlet channel on the sidewall of side base plate.During the 3D printing device of application SLM technology prints part, laser beam
To irradiate metal powder layer, and generate metal bath, metal inevitably generates a part of big in fusing, process of setting
Grain oxide, in this programme, inlet channel is provided for inputting the noble gas of protectiveness in working chamber, it is to avoid metal exists
Reacting with other gases under high temperature, bulky grain oxide will enter under the effect of noble gas together with noble gas simultaneously
Enter to inhale in powder groove and be collected by filtration.Owing to existing base plate is ledge structure, the turning recess of step is easily piled up substantial amounts of
Oxide particle, in this programme guide part be provided for fill base plate turning recess, beneficially bulky grain oxide with
Protective gas enters inhales powder groove, it is to avoid what bulky grain oxide affected part in remaining in laser forming district finally shapes effect
Really.
For this utility model is better achieved, described guide part is tilting structure, and angle of inclination is less than 45 °.We
In case, guide part is that tilting structure and angle of inclination are less than 45 °, it is possible to serves bulky grain oxide and preferably guides work
With, it is ensured that bulky grain oxide is effectively sent in suction powder groove and is collected by filtration.
In sum, Advantageous Effects of the present utility model is as follows:
1, the turning recess being provided for filling base plate of guide part, beneficially bulky grain oxide is with protective gas
Enter and inhale powder groove, it is to avoid bulky grain oxide affects the final forming effect of part in remaining in laser forming district.
2, inlet channel be provided for inputting the noble gas of protectiveness in working chamber, it is to avoid metal at high temperature with
Other gases react, and bulky grain oxide will enter suction powder groove under the effect of noble gas together with noble gas simultaneously
In be collected by filtration.
3, guide part is that tilting structure and angle of inclination are less than 45 °, it is possible to serve bulky grain oxide preferably
Guiding function, it is ensured that bulky grain oxide is effectively sent in suction powder groove and is collected by filtration.
