Specific embodiment
By that the present invention should will be more fully appreciated together with the detailed description below that institute's accompanying drawings are read.Herein
The middle specific embodiment for disclosing the present invention；However, it should be understood that revealed embodiment only has the exemplary of the present invention, the present invention
It can embody in a variety of manners.Therefore, specific function details disclosed herein is not interpreted as limiting, but only
It is construed to the basis of claims and is construed to teach those skilled in the art in fact any appropriate detailed
Representative basis using the present invention in different ways in embodiment.
With reference to shown in Fig. 1, powder sintered 3D printing system, including horizontal work top 1, the shaping that can move up and down
Workbench 5, powdering disk roller 6 and the confession material cylinder 4 of 5 both sides of forming worktable and rewinding cylinder 3 are divided into, powdering disk roller 6 is displaced into
For between material cylinder 4 and rewinding cylinder 3, after one layer of powdering and sintering is completed, forming worktable 5 declines one layer of depth of section.
It is corresponding to the demand of powder with formed product for powder amount for material cylinder 4 during formed product.
During formed product, due to the variation of sectional area, cause different layers different to the demand of powder, in order to save
The use of powder can carry out the supply of powder corresponding feed for material cylinder with every layer of demand to powder, the correspondence at this,
It is that confession under directions powder amount increases as demand increases, and is reduced as demand reduces.
In one embodiment, material cylinder is provided with driving device, which can move up and down that powder is promoted to go out
Cylinder, by the displacement moved up and down to control the quantity of every layer of discharging, driving device is controlled by microcontroller, and microcontroller is to be formed
Product carry out three-dimensional modeling, and the pre-stored data per formable layer, pass through the thickness to every layer of powder（Thickness can be preset）、
And the sectional area of this layer can accurately calculate demand of this layer to powder, and the demand then is corresponded to driving device
Displacement.
In one embodiment, driving device can be cylinder, for control accuracy, or motor and feed screw nut's
Combination.
In the technical solution, forming worktable is arranged in moulding cylinder 2, and bottom is connected with power set.Power set
It can be cylinder, or the combination of motor and feed screw nut.
With reference to shown in Fig. 2, in the first embodiment, for every layer of material cylinder for powder amount with the sectional area size of every formable layer
And it synchronously increases or reduces.
In the technical solution, each layer for powder amount is required to change the changes in demand of powder with this layer, specifically
Ground when demand is big, needs to increase supply on demand for powder amount；When demand is few, need to reduce confession on demand for powder amount
Should, it avoids wasting.
In this case, for powder amount simply as demand synchronously changes, and and it is non-required how many and accurately provide how much, it is actual
In operating process, supply generally can be larger than demand, and the amount beyond part can be a fixed value of setting,
It is exactly that each layer of confession is seasonable, supplies the amounts of certain values more, ensures the needs of sinter molding.
With reference to shown in Fig. 3, in a second embodiment, using n-layer（Positive integer）As a unit, wherein n >=2, every
It is identical for powder amount for material cylinder in a unit.
In the technical solution, during formed product, molding number of plies quantity is often very big, is needed between adjacent two layers
The difference of powder amount is wanted almost to can be ignored, therefore considers the interim difference for supplying powder.
With reference to shown in Fig. 4, in the third embodiment, certain value a can be set（Sectional area）, in the sectional area of formed product
In variation tendency, the difference d of maximum and minimum value for sectional area during same tendency, should if meeting d≤a
It is identical for powder amount for every layer of material cylinder during tendency.
Same tendency at this refers to the process of ascendant trend or the process of downward trend.
In the technical solution, it also is contemplated that be during formed product, if the sectional area of fruit product is in certain layer
Its variation is little between number quantity, then every layer can be kept in the excursion identical to supply powder amount.
If d ＞ a, during the tendency of the sectional area, meet one of following conditions for powder amount：
（1）, for every layer of material cylinder for powder amount and the proportional relation of sectional area of the formable layer（Embodiment one）；
（2）, using n-layer as a unit, wherein n >=2, it is identical for powder amount for material cylinder in each unit（Embodiment
Two）.
In one embodiment, the depth of section that forming worktable declines every time is identical.
In conclusion the present invention for powder amount with the variation of shaped article sectional area adaptive change, can realize
The accurate supply of powder, avoids the waste of powder, substantially reduces cost.
