Specific embodiment

In embodiment and attached drawing, element that is identical or playing phase same-action can be respectively equipped with identical appended drawing reference. Shown element and its mutual size relation are not to be taken as perspec-tive in principle, more specifically in order to preferably may be used It is illustrative and/or for a better understanding, each element can by overstate thick ground or large determine size in a manner of show.

Fig. 1 to Figure 14 is particularly depicted in increasing material manufacturing, especially corresponding coating method and equipment and the prior art Method in known aspect and relationship.

In particular, Fig. 1 shows the schematic cross sectional views or side view of equipment 30.Equipment 30 includes construction platform 2.The building Platform 2 is preferably provided in powder bed or powder 1.In order to construct component by corresponding powder bed method, excellent choice of powder is to structure The manufacture face HF of Jianping platform and/or the layer (not being explicitly illustrated in Fig. 1) having been built up carry out coating.It is equipped with applicator thus 32, the applicator can be guided on suspension 31 or correspondingly be moved by the suspension.Applicator 32 for example can be by machine Device control.Preferably, applicator in order to carry out new powder coating along the direction of motion or coating direction BUR (seeing below) when It is preceding to be directed through manufacture face HF from left to right, and new powder bed is coated herein.Then for example can by means of laser or Electron beam exposes according to desired geometry, melts and solidifies new powder bed.

Fig. 2 shows the schematic plans of the equipment in Fig. 1.Limit the arrow of coating direction BUR and applicator direction BR Fig. 1 and Fig. 2 should be currently particularly suitable for.

It can be seen that in Fig. 2, applicator 32 extends along manufacture face HF (referring to Y-axis).Applicator 32 can have roller, scrape Knife, scraper plate, brush or other suitable design schemes.

Fig. 3 shows component 10, and the component is arranged on for example conventional construction platform 2.According to the side based on powder bed Method, the usually successively decline during increasing material building component 10 of construction platform 2.This is carried out preferably via descending device 20.

The component further includes seamed edge or seamed edge profile 11.

Fig. 4 shows the schematic plan of component or corresponding construction platform in Fig. 3.It especially can be seen that, the component It is arranged or is oriented relative to construction platform 2, so that seamed edge 11 is parallel to the seamed edge orientation of construction platform 2.If set according to this Mode, applicator 32 (referring to fig. 2) are set, such as manufacture face HF is horizontally moved through according to coating direction BUR, wherein the system The face HF of making can equally be limited by the layer having been built up, to coat new powder bed, then applicator is at a time The seamed edge 11 of component 10 is encountered (referring to indicating applicator face or coating with its entire width (the applicator face BF in referring to fig. 2) The dotted line of device).When the process repeats layer by layer during constructing the component and then coating defect can spread or increase, this It can cause non-uniform coating result or coating defect in sizable degree.

In order to solve this problem, such as can be arranged on construction platform 2 according to the view of Fig. 5 and Fig. 6 or orientation member 10.It is for example shown in Fig. 6, the profile or seamed edge 11 of component 10 are not parallel to the lateral edges orientation of construction platform, and therefore It is not parallel to coating direction BUR orientation.Therefore, applicator (referring again to the dotted line in Fig. 6) can only encounter component 10 first One corner 13 or vertical seamed edge, however described coating defect hardly occurs.

Fig. 7 shows the schematic side elevation of another component 10.The schematic plan of the component is shown in FIG. 8.

The component 10 especially has first area B1.First area B1 can be the matrix or base regions of component 10. Second area B2 is also constructed and drawn on the B1 of first area.Second area B2 for example can be functional area.

Shape to both first area B1 and second area B2 rectangular-shape.However, first area B1's and second area The seamed edge profile (referring to appended drawing reference 11) of B2 is torsionally arranged opposite to each other according to the geometry of the individual of component 10, so that The lateral edges 11 of first area B1 and the lateral edges 11 of second area B2 are not parallel.

In order to enumerate specific example, component 10 can be turbo blade, and wherein first area B1 indicates root of blade, and Second area B2 for example indicates actual blade.In this component that is complicated, being especially non-cuboid, seamed edge profile edge Component building direction (from bottom to top) variation so that in order to avoid the shortcomings that currently mentioning in coating, it is necessary to find use In the compromise proposal of orientation of the component 10 on construction platform 2 (referring to Figure 13 and Figure 14 more hereafter).

When the component 10 in Fig. 7 is for example arranged on construction platform 2 according to Fig. 9 and Figure 10, applicator 32 is for example first The corner 13 (referring to Fig.1 0 in dotted line) of the first area B1 of component 10 can be encountered again, and the applicator is from left side along coating Direction BUR carries out coating (referring to Fig.1 0) to manufacture face HF.In the later point of building, i.e., when the building has advanced into directly When to second area B2, the seamed edge 11 of second area can be encountered with the entire width of applicator 32 again.

If component is oriented according to Figure 11 and Figure 12, the process on the contrary, and the first area B1 of component 10 rib Side 11 can be coated device 32 and bump against and cause corresponding coating defect, although the coating defect is in order to construct second area B2 It can be eliminated.

Figure 13 shows described set-up mode of the component 10 on construction platform 2, at least very big according to the set-up mode The described coating defect during increasing material building is prevented in degree.This especially such case because when applicator according to When coating direction BUR moves through manufacture face, the seamed edge of first area and the seamed edge of second area are all not parallel to applicator face BF or the orientation of applicator 32 (referring to Fig.1 4 in dotted line).

The extension of region B1, B2 shown in Figure 13 highly preferred is equivalent to single cured layer (referring to Fig.1 in 3 Appended drawing reference 12) several times, the layer equally shows with dotted line.

However the component according to shape complexity increasing material manufacturing unrelated with corresponding technical field, wherein being led in the technology These components are used in domain, are found as this compromise proposal being shown in FIG. 14 is often difficult or even can not , once because single layer is several times cured on the construction platform, can hardly subsequently change component relative to The orientation of construction platform.

Figure 15 to 18 describes solution according to the present invention, the solution allow for example from the beginning and with The initial orientation of corresponding component independently solves the problems, such as coating defect.

Figure 15 shows the schematic side elevation or cross-sectional view of equipment 50 according to the present invention.Equipment 50 according to the present invention is same Sample includes construction platform 2.Equipment 50 further includes suspension 61, and applicator 60 is suitably coupled in a manner of movable or is moveable On the suspension.According to the view of Fig. 1, equipment 50 is preferably configured as the powder for will be used for increasing material manufacturing by means of applicator 60 Last layer or powder synusia are applied on the HF of manufacture face.This preferably as shown according to coating direction BUR from left to right into Row.

Construction platform 2 is preferably circular, and the corresponding diagrammatic top such as in Figure 16 in equipment 50 is as shown in the figure.

According to the present invention, construction platform 2 and/or the rest part of equipment, including what is be made of suspension 61 and applicator 60 Cladding apparatus can be moved around pivot center DA.In particular, construction platform 2 and remaining component can preferably surround independently of one another Pivot center DA movement or rotation.The design scheme can be realized during increasing material manufacturing to component or each for the structure The adjustment of the orientation of the layer (being not explicitly shown) of part building, so that the applicator face BF of applicator 60 is not preferably entire wide along it Degree (referring to Fig.1 6 in Y-axis) is encountered on the seamed edge of corresponding component and preferably not always in the same area along seamed edge On.

With the difference being shown in FIG. 16, cladding apparatus, i.e. suspension 61 and applicator 60 can preferably pass through suitable side Formula completely moves downwards and again up from construction platform 2, so that when the powdered base material to coat again is (referring to Fig.1 in 6 Appended drawing reference 1) preferably not with manufacture face HF contact when, carry out such as rotation of the construction platform 2 relative to coating equipment.It is no Then, this may result in undesirable powder particles (eddy motion) and equally damages manufacturing quality.

It according to Figure 15, Figure 16 and Figure 17, currently proposes and describes according to the method for the present invention, the method, which solves, to be worked as The preceding coating problems being directed to.

Method and step b) describes the applicator direction BR for the powder bed to newly apply relative to detected seamed edge The orientation of profile 11 is different from so that increasing seamed edge 11 and applicator direction BR formation that is material building or increasing the layer 12 of material building 90 ° of angle.Correspondingly, angle [alpha] is shown in FIG. 16, which is preferably different from 0 ° and 90 °, especially it is greater than 20 °, and And show the relative rotation between the seamed edge profile 11 and coating direction BUR of layer 12.Applicator direction BR can with it is described Coating direction BUR consistent (referring to figs. 1 to Figure 16).

Mentioned orientation can be implemented as so that particularly by make applicator and/or Coating installation relative to seamed edge wheel Exterior feature 11 or the rotation of component 10 are to change applicator direction BR.

Alternatively or additionally, in order to change the orientation and applicator direction unfavorable for coating result of component, building Platform rotates preferably together with the element structure being disposed thereon when necessary relative to applicator direction.

Corresponding orientation can equally be realized as follows: especially for newly applying and then cured layer is wanted to implement structure The change of part design.

Preferably realize orientation layer by layer and based on calculating according to the present invention, it is described to calculate by being used for increasing material manufacturing structure CAD the and/or CAM data of part or the data therefrom derived assist.

Preferably, according to the present invention, after the layer 12 in each building for component 10 according to or by detecting to check, Whether seamed edge 11 is different from 90 ° of angle (referring to α) with applicator direction BR formation, and wherein again fixed in negative To applicator direction BR.

In some cases, and not always or for all seamed edge regions or seamed edge point it is possible that especially in circle Profile in the case where, all the points of seamed edge or its tangent line and applicator direction BR, which are formed, is different from 90 ° of angle.

However, if the part as big as possible of many points or corresponding seamed edge correspondingly forms not with applicator direction BR 90 ° of different (limited) angles are same as, then the problem of being also able to solve according to the present invention.

In the case where the seamed edge profile of round or ellipse, applicator direction BR preferably layer by layer, i.e., each building Layer, change or " continuing to rotate " during increasing material and constructing the component, so that existing along the seamed edge profile " adversely " setting On always other or successively different points on the profile or seamed edge, this means, point finally referred on seamed edge or position Solving the problems, such as according to the present invention still occurs in the place of setting.

The alternative solution that described method is especially proposed in Figure 18 and Figure 19, is set by according to the present invention Applicator standby and being shown in FIG. 18 is realized.

In the view of Figure 18 and Figure 19, pass through applicator or the design scheme of Coating installation, applicator direction BR such as institute Coating direction BUR described in the deviation shown.
