Description
Technical field
The present invention relates to a kind of 3D printers with gradient powder-supply system, belong to material increasing field.
Background technique
Functionally gradient material (FGM) refers to the different material of two or more performance, by the composition and knot that change these materials
Structure gradually changes it without interface, and the material formed.This novel design of material thought of functionally gradient material (FGM), once proposition,
Cause the great attention of countries in the world material science worker immediately and it be unfolded to study, main preparation methods have powder at
Type, physical vaporous deposition (PVD), chemical vapour deposition technique (CVD), plasma spraying, electrocasting, galvanoplastic, self- propagating are high
Warm synthetic method etc., these methods are required to complicated technique or equipment, lack easy preparation method, are limitation function gradient materials
Expect the major reason further developed.
With the fast development of 3D printing technique, extensive concern is obtained with the research that 3D printing method carries out functionally gradient material (FGM),
If patent CN104923787A describes a kind of 3D printing method of functionally gradient material (FGM) structure, using a set of power spreading device and a set of paving
Powder spray head realizes the mixing of two kinds of materials, and makes powder material forming using laser.Powdering spray head in the invention uses gas
Powder feeding can generate the effect of power to powder existing in forming platform when dusting, the powder in forming platform is caused to be dispelled,
Under the influence of one layer of powdering, the final component gradient control and size Control for influencing part.Patent CN104439243A is described
A kind of laser 3D printing preparation method of metal gradient material passes through the powder group in control powder feeder by the way of dusting
Point ratio, achievees the purpose that control metal gradient, it using laser cladding method, invent the parts size precision of preparation compared with
Difference.Patent CN106735214A describes the 3D printing device and 3D printing forming method of a kind of Functional Gradient Materials, adopts
With two hoppers, need which kind of material just by that corresponding hopper delivery powdering.Patent CN108213425A describes a kind of use
Mix uniformly distributed method and device in the powder of gradient material component 3D printing, the two patents be single layer be homogenous material or
Uniform composition material is not the material continuously changed proportionally, and the uniformly distributed step of powder mixing is many and diverse.
Patent CN108480630A describe it is a kind of based on selective laser melting process prepare functionally gradient material (FGM) device and
Method, the device include laser scanning galvanometer and the powder-storing machine set gradually from top to bottom, meal mixer, powder-wiping plate, workbench, with
Phase realizes that horizontal plane along the change of gradient perpendicular to powdering direction material composition, only emphasizes that powder-storing machine outlet at bottom is rectangular
Shape, powder-storing machine section or in double anti-triangles or in three symmetrical triangles or be in four combined triangular shapes, but its none it is accurate
Powder feeder unit, not can guarantee various powders volume ratio always as required, it is quantitative always accurately drop into meal mixer, like that
Just be difficult to realize horizontal plane along perpendicular to powdering direction material composition ratio be always it is constant, just not can guarantee forming height
The ratio of material composition is constant or consistent on direction, in this way to the design of functionally gradient material (FGM) and research, to functionally graded material
Development and application have an adverse effect.Thus it is guaranteed that two or more powder volume ratio always as required, quantitative always
It accurately drops into meal mixer, guarantees each powdering layer horizontal plane along the change of gradient ratio perpendicular to powdering direction material composition
Example is constant such a gradient powder-supply system always and develops a kind of 3D printing with such gradient powder-supply system
Machine just seems very urgent.

Shown in reference picture 1, Fig. 2, which illustrates the arrangement of the 3D printer embodiment complete machine with gradient powder-supply system
Figure, using front and back powdering, powder-supply system has preceding blanking system more than workbench, before moulding cylinder, falls after having behind moulding cylinder
Material system, is the discharge port of the accurate feeding device of gradient powder-supply system between moulding cylinder and rear blanking system, moulding cylinder just on
Side is the optical systems such as galvanometer, laser, beam expanding lens, and entire mechanism is placed in seal case, in the course of work in seal case
It is filled with inert protective gas, inert protective gas is recycled after dust separation system.Before processing, first by each accumulator
Filling up required powder, seal case is closed and filling with inert gas, and moulding cylinder rises to work top, scraper to starting operating position,
It is between rear blanking system and accurate feeding device discharge port, reaches required process conditions and start to process, moulding cylinder decline
One thickness, feeding system powder supply is primary, powder is paved with moulding cylinder upper surface by powdering system driving scraper, then laser
It starts to work with galvanometer, carries out precinct laser sintering processing.
Shown in Fig. 3 to Fig. 9, this is that there are two the embodiment that accumulator, powder organiser have a partition, Fig. 3 for a kind of band
It is shown be the powder feeder of embodiment piston on have wide strip grooves channel as powder organiser, in pan feeding state, two
The powder of a accumulator is divided into two regions by powder organiser, and falls into the corresponding region of the strip grooves of loader piston
In, since strip groove width is identical with powder organiser groove width, the volume ratio of two kinds of powders in slot will not be changed, then, supplied
The piston of powder device moves in X direction, arrives position as shown in Figure 4, and powder reaches at accurate powder feeder outlet charging conduit in piston, warp
Mixer make two kinds of powders in outlet X-direction component be it is uniform, be in vertical X axis direction it is different by design gradient, then
It falling on workbench, powdering system drives scraper that powder is covered with moulding cylinder upper surface, it is covered with this layer of powder of moulding cylinder upper surface,
Component is consistent in X direction, is by design component consecutive variations or change of gradient along vertical X-direction.
Fig. 5 to Fig. 6 is similar with Fig. 3 Fig. 4, and difference is, the slot wide as powder organiser on powder feeder piston
In channel, have in powder organiser partition guarantee that the powder of each accumulator is fallen into so as shown in figures 7 and 9
In respective slot, guarantee that volume ratio is more accurate.
Certainly, and so on, two or more powders also may be implemented.In the embodiment shown in fig. 10, powder is illustrated
In organiser there are two partition, there are three accumulator, the case where three kinds of powder gradient mixings, and powder organiser may be implemented
Strip slot can be rectangle frame as shown in Figure 10, also allow non-rectangle frame as shown in figure 11, in powder organiser some every
Plate can be straight baffle as shown in Figure 10, be also possible to folded plate or curved slab.
Above-described is only the preferred embodiment of the present invention.It should be pointed out that coming for those of ordinary skill in the art
It says, under the premise of not departing from the principle of the invention and core concept, several modifications and improvements can also be made, be also considered as belonging to this
The protection scope of invention.
