Summary of the invention

It is an object of the present invention to provide a kind of devices of increasing material manufacturing three-dimension object, wherein improves building material Application particularly construct the distribution of material.

The purpose is creatively realized by device according to claim 1.Advantageous embodiment of the invention be limited to from Belong to claim.

The device of described in the text is a kind of by means of continuous selective layering consolidated powder shape building material (" building material Material ") layer carry out the device of increasing material manufacturing three-dimension object (e.g., technical component), building material can by means of energy source as can Beam (particularly, laser beam or electron beam) is measured to consolidate.Corresponding building material can be metal, ceramics or polymer powder. Corresponding energy beam can be laser beam or electron beam.For example, corresponding device can be and wherein be performed separately building material Application and construct material consolidation device, such as selective laser sintering device, selective laser melting device or selection Property Electron beam melting devices.Alternately, the continuous stratification that building material can be executed via at least one jointing material selects Property consolidation.Jointing material can use corresponding applying unit and apply, and for example utilize suitable energy source (such as UV light source) Irradiation.

The device may include the several functional units used during its operation.Exemplary functional unit is processing Room, irradiation apparatus and flowing generate equipment, and irradiation apparatus is adapted to selectively irradiate placement using at least one energy beam Layers of build material in the process chamber, flowing generates equipment and is adapted to generate, and there is given flowing property (e.g., to give flow model Line, flow rate etc.) and at least partly flow through the flow of gaseous fluid of process chamber.Flow of gaseous fluid is flowing through processing The unconsolidated particles shape building material (smog or cigarette particularly, generated during equipment operation can be inflated while room Mist residue).Flow of gaseous fluid is usually inert, that is, is usually inert gas (e.g., argon, nitrogen, carbon dioxide etc.) stream.

As previously mentioned, the device includes applying unit the present invention relates to a kind of device of increasing material manufacturing three-dimension object, apply Unit, which provides, applies element, and using element is applied, building material can be transmitted to building plane and be distributed in building plane. The present invention is based on following thoughts: applying unit is adapted to control and applies the rate of application that element is moved across building plane, wherein Applying unit is adapted to apply state modulator rate of application according at least one.For (e.g., from charging module) transmission " new " Material is constructed, new building material is provided in increasing material manufacturing processing, applying unit makes application element be moved across building plane. For example, the charging plane for the charging module that new building material can be arranged applies before building plane on applying direction Element is moved to be transmitted to the plane from the new building material of charging planar pickup and by building material along applying direction, via Application element (equably) is distributed in the plane.

Therefore, the present invention is based on following thoughts: limiting the application speed for applying the rate of element mobile (crossing building plane) Rate can be changed, to directly affect the application quality for the building material being applied in building plane.Particularly, if applying matter Amount does not meet the quality requirement of restriction, for example, the building material in building plane is not distributed suitably, then can reduce application speed Rate.Due to the control of rate of application, particularly, reduce rate of application, can more uniformly be distributed building material, thus with utilization Apply building material with the mobile identical application element of relatively high rate of application to compare, realizes higher application quality.It changes Yan Zhi can be suitable for the rate of application for being suitably distributed building material to move application element.On the other hand, as quickly as possible The mobile element that applies is without lowering application quality, to ensure to reduce the overall processing time of increasing material manufacturing processing as much as possible.

Then, applying element can slowly and as quickly as possible move depending on needed for, to realize the application matter limited It measures and is quickly accomplished increasing material manufacturing processing, particularly, each application step as much as possible.For example, if with the charging of restriction The factor, which executes, applies step, which, which limits, provides the amount for the building material being applied in building plane, and does not meet The application quality of restriction, then can reduce rate of application, to realize the application of the building material for the application quality for meeting restriction.Separately On the one hand, rate of application can be increased, until detecting the attenuating for applying quality, to ensure that fast application structure can be found Construction material and suitably conform to apply quality between compromise.Thus, especially it not will increase application matter in the increase charging factor Under the situation of amount, quality can be applied in improvement with power-assisted by reducing rate of application.Therefore, it is possible to substantially reduce not solid in application processing The waste of structure construction material, and application quality can be improved.

The first embodiment of device according to the present invention, applying unit may include control unit or can be with control units Connection can connect, and control unit is adapted to control rate of application.Control unit can be constructed as or be interpreted as internal or external Control unit, wherein control unit can be the internal control unit of applying unit, or be configured to outer outside applying unit Portion's control unit, and can connect or can connect with applying unit.Control unit is adapted to generate or send corresponding (control) Signal can move application element based on the signal.

Particularly, rate of application can be limited via control unit.It is possible that respectively, applying parameter and being sent to control Unit processed or control unit, which receive, applies parameter, wherein control unit is adapted to based on application state modulator rate of application.Example Such as, if the application quality for applying the applied layer that parameter instruction has the attenuating for applying quality or building material does not meet restriction Application quality, then thus control unit can control or regulate rate of application to ensure apply the building material in building plane The application quality of material meets the application quality of restriction.

Building plane is moved across in order to make to apply element, it is preferable that applying unit includes driving unit, especially horse It reaches, driving unit is adapted to preferably according to from least one received signal of control unit, and driving applies element to apply speed Rate crosses building plane.Thus, applying unit may include driving unit, and driving unit interacts with element is applied so as to apply Canadian dollar part is moved across building plane, building material is transmitted and be distributed in building plane.For example, applying element can construct For rake or the coating machine element of similar rake, particularly, coating machine scraper applies element and moves in charging plane to pick up New building material simultaneously makes to construct material from charging planar movement (push/pull) to building plane, wherein building material (equably) Distribution constructs the mew layer of material to be formed on constructing plate or previous application (and partial consolidation) layer for constructing material.According to control Unit is sent to the control signal of driving unit, and adjustable or control applies the application speed that element is moved across building plane Rate.

As previously mentioned, rate of application has a direct impact to quality is applied, because the distribution for constructing material in building plane is (special Not, construct plane in construct material conforming layer application) depend largely on apply element building plane on move Rate.Therefore, rate of application can be reduced to the rate of application of restriction, via the rate of application, may be implemented increasing material In manufacture processing there is currently circumstances and under the conditions of construct the application of material and meet the application quality of restriction.

Preferably, applying unit can be adapted to automatically control rate of application.For example, applying unit can receive (that is, base Sent in confirmable application parameter via control unit) to induction signal, as will be described below, wherein can be based on Apply the automatic control that parameter executes rate of application.Lower if receiving and applying quality, can be determined by control unit Corresponding application parameter, wherein can control driving unit, so that reducing the rate of application for applying element, thus to ensure to apply The building material being added in building plane is suitably distributed.Rate of application can also be increased, until determining that applying quality attenuating is Only, wherein high rate of application and the compromise appropriate applied between quality can also be automatically found.

For example, applying unit can be adapted to execute calibration procedure (test applies) automatically, wherein can find for increasing The best rate of application of condition present in material manufacture processing, wherein material can will be constructed with the rate of application of restriction and applied To building plane.Rate of application can be lowered, until reaching the application quality of restriction, alternatively, applying unit can be adapted to At increase rate of application, until detecting that applying quality lowers.Therefore, in two ways, can detecte application element can To be moved across the maximum rate of application of building plane, and wherein still conform to the application quality limited.Therefore, it is possible to automatic Find the compromise reduced between processing time and the processing quality for realizing restriction.Thus it is possible to based on that can determine and control is applied Rate of acceleration and execute test apply.Of course, it is possible to rate of application determined by being verified in entire increasing material manufacturing processing, for example, At defined intervals or randomly.

As previously mentioned, the rate of application for applying element and being moved across building plane can be controlled according to parameter is applied.It applies Add parameter that can limit the condition for executing and applying processing, which directly affects or describes the condition for influencing to apply quality, Therefore, directly affect or describe whether rate of application is suitable for applying building material under those qualifications.Generally, facilitate Or description or influence any parameter of the application quality of application building material in building plane are all used as applying parameter, Or it may be embodied in and apply in parameter.

Particularly, apply parameter can be, or particularly may include building material application quality and/or particle it is big The physically or chemically ginseng of the type and/or building material of small and/or building material particle size distribution and/or building material Number, particularly, humidity.Therefore, applying parameter and can be to apply quality or can be associated, and applying quality for example can be via Respective sensor detects or determines, as will be described below.Therefore, the control that quality executes rate of application can be applied with direct basis System, wherein for example, can detecte application quality, and therefore, if it is determined that apply quality and lower, then reduce rate of application.Also The rate of application for applying element can be controlled according to the type of building material used in handling in increasing material manufacturing, for example, making Use metal or ceramics or synthetic material as building material.Can also be different between different types of material, such as aluminium And/or steel and/or titanium, and on the specific distribution behavior for these materials that will be applied in building plane it is different.

Additionally or alternately, can make to apply the granular size and/or building material that parameter includes building material Particle size distribution.The granular size of building material used in increasing material manufacturing processing largely influences building material and exists Construct behavior when applying in plane.Equally, the particle size distribution of material is constructed, that is, having different size, (e.g., particle is straight Diameter) variable grain presence also influence construct material distribution behavior.For example, with building material granule it is larger or building material Material is compared comprising the particle size distribution with a high proportion of bulky grain, and building material granule is smaller or building material includes tool There is a high proportion of short grained particle size distribution that can more uniformly and/or more easily be distributed in building plane.

In other words, with use the particle size distribution comprising big building material granule or comprising a high proportion of bulky grain The application step of building material compares, if building material is comprising (relatively) small building material granule or comprising at high proportion Short grained particle size distribution then can increase rate of application.Vice versa, if used building material includes Big building material granule or the particle size distribution comprising high proportion bulky grain, then can reduce rate of application to ensure still to accord with Close the application quality limited.

Apparatus of the present invention can be advantageously improved in can be set and be adapted to determine that at least one applies parameter order really Member.As previously mentioned, applying parameter can be, or it may include the application quality for constructing material and/or granular size and/or structure The particle size distribution of construction material and/or the type for constructing material.It can be set according to this embodiment of the apparatus according to the invention really Order member applies parameter for determining.Accordingly, it is determined that unit can determine application parameter, wherein can be (special to applying unit Not, to control unit) identified application parameter is provided, wherein it can be executed based on identified application parameter and apply speed The automatic control of rate.

Preferably, determination unit can be, or, it is preferable that determination unit may include at least one optical sensor, Particularly, CCD or cmos sensor, it is preferable that camera.It is applied accordingly, it is determined that the optical sensor of unit can be used to determine Add parameter, as previously described.For example, the image of the available building material of applying unit is to export the granular size for constructing material And/or particle size distribution.The type of building material can also be exported via determination unit, as previously described.Structure can also be obtained Whether (particularly, constructing the previous applied layer of the material) image in Jianping face, and the application of export building material meet limit Fixed application quality.

For example, following determinations can be executed: whether the last applied layer for constructing material suitably covers building plane, realizes The thickness degree limited, alternatively, whether can see each section of object to be manufactured by last applied layer.It can also export, Whether the previous applied layer of building material is uniformly distributed, alternatively, the building plane not applied suitably with the presence or absence of building material Region.According to the application parameter for exporting or determining via determination unit, the control of rate of application can be executed, as previously described.

Preferably, applying unit can be adapted to apply building material again according at least one application parameter, particularly, With identical or different rate of application.For example, the previous applied layer of building material can be obtained via determination unit, wherein such as Fruit determination unit determines that the previous applied layer of building material is not applied to the application quality for meeting restriction, that is, building material is uneven It is distributed in building plane evenly, then applying unit can apply the layer of building material again, for example to fill building plane Gap.The application again of the layer of building material can be executed with identical or different rate of application, wherein applying unit is (especially Ground, control unit) rate of application can be adjusted or controlled according to parameter selection is applied.

Other preferred embodiment of the apparatus according to the invention, applying unit can be adapted to flat for object and/or building Differently control applies at least two regions (at least two regions of the identical layer for the building material particularly, to be applied) in face Rate.Thus, applying unit can change the rate of application of building material during applying step, wherein building material is in structure Applied at least two regions in Jianping face with different rate of application.For example, charging plane and building plane can also be changed Between rate of application.Thus, applying element can be in charging plane than moving faster in building plane.Certainly, Multiple regions can be limited, wherein with independent rate of application is mobile can apply element in side on each zone.

Particularly, at least two regions can be located in the identical layer for the building material to be applied, wherein can also make to apply Unit is added differently to change rate of application for two different layers of building material, wherein for example, in each of two layers Rate of application can be uniformly selected or differently select at least two regions of layer.For example, can be in building plane At least two regions between distinguish, for example, about for these regions restriction application quality.Therefore, it is possible to have There is at least one region of relatively high quality requirement, therefore, it is necessary to the rate of application in the region is accordingly controlled, and In another region required not comprising high quality, rate of application can be increased, apply building material required time to save, To reduce overall processing time as much as possible.

About previous embodiment, at least one region can be the area to be irradiated in increasing material manufacturing processing of building plane Domain, and at least one other region can be the region that do not irradiate in increasing material manufacturing processing of building plane.Thus, it can Differently to control rate of application at least two regions, wherein a region will be irradiated and another in increasing material manufacturing processing One region not irradiated in increasing material manufacturing processing.Then, opposite for the quality requirement in the region of the building plane to be irradiated It is higher, because to be irradiated in this region in increasing material manufacturing processing and with this fixing structure construction material, and handled in increasing material manufacturing In other regions that not irradiate do not force this quality requirement because not irradiate building material in such a region.Therefore, Rate of application can be differently adjusted at least two regions, to ensure to fit in the region to be irradiated in increasing material manufacturing processing Locality meets application quality, and can increase rate of application in the region that do not irradiate in increasing material manufacturing processing, is applied with saving Add the time in step.

Applying unit can be further adapted to the control charging factor, and the charging factor limits: to apply the structure that step provides The amount of construction material.As previously mentioned, the charging factor, which limits, provides the amount for the building material being applied in building plane.For example, can be with Setting charging module, building module and overflow module in increasing material manufacturing equipment, wherein charging module includes feed compartment, new Material is constructed to receive in feed compartment to apply in increasing material manufacturing is handled.Module is constructed to provide for receiving via charging module Building material and increasing material manufacturing processing in carry object, according to by via charging module provide building layers of material and Continuously construct object.Overflow module is adapted to receive extra building material from building plane, wherein.Apply element constructing From charging planar movement in plane, extra building material is transmitted to the overflow module that can receive it.

By the control charging factor, offer can control via the transmission of application element and to be distributed in structure via element is applied The amount of building material in the face of Jianping.It is adjustable to apply the suitable of building material in building plane by changing the factor that feeds The amount of material is constructed necessary to layer, wherein the amount of extra building material can also be reduced.Therefore, it is possible to control charging because Son is to realize the amount of extra building material wasted in increasing material manufacturing processing and sufficiently high with ensure can be in applying step Apply the compromise between the charging factor of the appropriate layer of building material.Further, it is also possible to according to (for example, true via determination unit Fixed) the application state modulator charging factor, as previously described.

Another embodiment of device according to the present invention, applying unit can be adapted to input based at least one user to control Rate of application processed.Thus, user can select (e.g., via user interface) or adjustable rate of application.For example, user can be with The visual inspection of the applied layer of building material is executed, and adjusts rate of application according to the result of visual inspection.Then, Yong Huke To directly affect increasing material manufacturing processing, for example, the rate of application for applying element is directly controlled, for example to reduce overall processing time Or improve the application quality that building material is applied in building plane.

In addition, the device is by means of continuous stratification elective irradiation the present invention relates to a kind of applying unit for device And the layer of fixing structure construction material comes increasing material manufacturing three-dimension object (particularly, foregoing apparatus of the present invention), constructs material Layer can be consolidated by means of energy source, which includes applying unit, and applying unit is adapted to flat in building via element is applied Applying building material on face, wherein applying unit is adapted to control and applies the rate of application that element is moved across building plane, In, applying unit is adapted to apply state modulator rate of application according at least one.
