當由本說明書或該等請求項引用時,以下的術語會被理解為係指以下的意義。單數形式「一」、「一個」、和「該」的意思是指「一個或多個」。術語「包括」和「具有」旨在具有相同的包容性意義,如同術語「包含有」。 When referenced by this specification or the claims, the following terms are understood to mean the following meanings. The singular forms "a", "an" and "the" are meant to mean "one or more." The terms "including" and "having" are intended to have the same inclusive meaning as the term "includes".
使用一積層製造系統,一三維物件可透過建構材料的一個或多個連續層其部分的固化來被產生。該建構材料可以是基於粉末的而所產生物件的該等屬性係取決於該建構材料的類型和所使用之固化機制的類型。在一些實例中,固化的實現可以使用一種液體粘合劑來化學式地固化建構材料。在其他的實例中,固化的實現可透過把能量暫時性地施加到該建構材料。這可以,舉例來說,涉及一聚結劑的使用,其係一種材料,當一適當量的能量被施加到 建構材料和聚結劑的一種組合時,可致使該建構材料聚結和固化。在其他的實例中,固化的其他方法可被使用。 Using a laminate manufacturing system, a three-dimensional object can be created by solidification of portions of one or more continuous layers of the construction material. The build material can be powder based and the properties of the resulting article depend on the type of build material and the type of cure mechanism used. In some examples, the implementation of curing can use a liquid binder to chemically cure the build material. In other examples, curing can be achieved by temporarily applying energy to the build material. This can, for example, involve the use of a coalescent, which is a material when an appropriate amount of energy is applied to A combination of building material and coalescent can cause the building material to coalesce and solidify. In other examples, other methods of curing can be used.
然而,一些積層製造系統的設計可能,舉例來說,無法提供足夠的靈活性和速度。舉例來說,當建構材料需要再次填充或該系統需要清理時,列印的連續性可能難以維持。此外,在列印作業之間可能會有時間延遲。再者,在一些實例中,這些系統可能需要有高度使用者互動的設計,諸如處理建構材料和清理。 However, the design of some laminate manufacturing systems may, for example, not provide sufficient flexibility and speed. For example, the continuity of the print may be difficult to maintain when the build material needs to be refilled or the system needs to be cleaned. In addition, there may be a time delay between print jobs. Moreover, in some instances, these systems may require highly user-interactive designs, such as processing construction materials and cleaning.
因此,本發明內容提供了建構模組,其可移除式地可插入至一種積層製造系統。該模組化設計可以,舉例來說,藉由在同一時間允許不同類型的建構模組被插入,諸如不同尺寸和/或多個建構模組,來提供多功能性。該模組化設計還可以透過允許更快的使用和在繼續使用該系統的過程中具有較少的中斷來使高生產率變得可能,舉例來說在連續性的列印作業之間會以很少或沒有時間延遲的方式來完成。該建構模組可被提供有一殼體,其中一建構腔、建構材料腔、和/或馬達可被提供用於該等腔的移動。這種設計可以允許一建構模組可更快速的清理,當它被移除時。該建構模組也可以容易地於一積層製造系統被插入和移除。 Accordingly, the present disclosure provides a construction module that is removably insertable into a laminated manufacturing system. The modular design can provide versatility, for example, by allowing different types of building blocks to be inserted at the same time, such as different sizes and/or multiple building blocks. The modular design also enables high productivity by allowing for faster use and less disruption in the continued use of the system, for example between successive print jobs. There is little or no time delay to complete. The construction module can be provided with a housing in which a construction cavity, a construction material cavity, and/or a motor can be provided for movement of the chambers.

For example, in FIG. 2g, a single construction module 214d has a length along the y-axis direction such that when it is inserted into the system 200, the entire y-axis length of the receiving volume 212 can be filled. In Figure 2f, a plurality of building blocks 214a-c having a smaller length along the y-axis direction can be aligned along the y-axis direction to collectively fill the entire receiving volume 212. Thus, in Figure 2f, the construction chambers and support members of the construction modules 214a-c can be arranged in columns. Moreover, in Figure 2f, construction modules having different lengths are illustrated, for example, the build modules 214a-c have different lengths relative to each other.

在圖2a所示的該實例中,該化劑分配器268有一在該x軸方向的長度使得它能夠以一種所謂的頁寬陣列配置跨越該支撐構件236或336在該x軸方向的整個寬度。在一實例中,這可透過多個列印頭的一種適當的佈置來被實現。在其他的實例中,一具有一噴嘴陣列的單一列印頭可 被使用,該噴嘴陣列具有一長度使得它們能夠跨越該支撐構件236或336的寬度。在其他的實例中,該化劑分配器268可以具有一較短的長度,其無法使它們能夠跨越該支撐構件236或336的整個寬度。 In the example shown in Figure 2a, the developer dispenser 268 has a length in the x-axis direction such that it can span the entire width of the support member 236 or 336 in the x-axis direction in a so-called page width array configuration. . In an example, this can be accomplished by a suitable arrangement of multiple printheads. In other examples, a single printhead having an array of nozzles can Used, the nozzle arrays have a length such that they can span the width of the support member 236 or 336. In other examples, the dispensers 268 can have a shorter length that does not enable them to span the entire width of the support member 236 or 336.
該分配器268可以被安裝在一可移動的滑架上以使其可沿著該所示的y軸雙向地移動過該串一個或多個支撐構件236或336的整個長度,如圖箭頭270所示。這使得可用一單次遍歷即能夠把聚結劑的選擇性遞送橫越過該等支撐構件236或336的整個寬度和長度。 The dispenser 268 can be mounted on a movable carriage such that it can move bi-directionally across the entire length of the string of one or more support members 236 or 336 along the illustrated y-axis, as shown by arrow 270. Shown. This allows selective delivery of coalescing agent across the entire width and length of the support members 236 or 336 with a single pass.
應當被注意的是,本文所使用的該術語「寬度」係一般用來表示在平行於圖2a-e中所示之該等x和y軸的平面中的最短尺寸,而本文所使用的該術語「長度」係一般用來表示在該平面中的該最長尺寸。然而,將被理解的是,在其他的實例中,該等術語「寬度」和「長度」係可互換使用。舉例來說,在其他的實例中,該化劑分配器268可具有一長度,其致使它們能夠跨越該支撐構件236或336的整個長度,而該可移動滑架可雙向地移動橫跨該支撐構件236或336的寬度。 It should be noted that the term "width" as used herein is generally used to mean the shortest dimension in a plane parallel to the x and y axes shown in Figures 2a-e, and as used herein. The term "length" is generally used to mean the longest dimension in the plane. However, it will be understood that in other instances, the terms "width" and "length" are used interchangeably. For example, in other examples, the chemical dispenser 268 can have a length that enables them to span the entire length of the support member 236 or 336, while the movable carriage can move bidirectionally across the support The width of member 236 or 336.
在另一實例中,該化劑分配器268並不具有一可使它們能夠跨越該支撐構件236或336整個寬度的長度,但另外地能在該圖示的該x軸中雙向地移動橫跨該支撐構件236或336的寬度。該配置使用多次遍歷來致使聚結劑和聚結改性劑的選擇性遞送可橫跨該支撐體204的整個寬度和長度。然而,其他的配置,諸如一頁寬陣列配置,可致使 三維物件可更快地被產生。 In another example, the developer dispenser 268 does not have a length that enables them to span the entire width of the support member 236 or 336, but otherwise can move bidirectionally across the x-axis of the illustration. The width of the support member 236 or 336. This configuration uses multiple traversals to cause selective delivery of coalescing and coalescing modifiers across the entire width and length of the support 204. However, other configurations, such as a one-page wide array configuration, can cause Three-dimensional objects can be produced faster.
該聚結劑分配器268可以包括一聚結劑的供給,或者可連接到一分離的聚結劑供給。 The coalescer dispenser 268 can include a supply of coalescing agent or can be coupled to a separate coalescing agent supply.

In some examples, the dispensers of system 200 can be located on the same carriage, not adjacent to one another or separated by a short distance. In other examples, each of the two or more carriages may contain one or more dispensers. For example, each dispenser can be located on its own respective carriage.

However, in some instances, different agent dispensers can provide different coalescing agents, for example.
該系統200還包括一附接到該殼體202的能量源272。該能量源272將施加能量給建構材料以致使該建構材料在聚結劑已被遞送或已經滲透的部分進行固化。在一些實例中,該能量源272係一紅外線(IR)輻射源、近紅外線輻射源、或鹵素輻射源。在一些實例中,該能量源272可以是一單一能量源,其能夠均勻地施加能量至沉積在該支撐構件236或336上的建構材料。在一些實例中,該能量源272可以包括一能量源陣列。 The system 200 also includes an energy source 272 attached to the housing 202. The energy source 272 will apply energy to the build material to cause the build material to cure at the portion of the coalescing agent that has been delivered or has penetrated. In some examples, the energy source 272 is an infrared (IR) radiation source, a near infrared radiation source, or a halogen radiation source. In some examples, the energy source 272 can be a single energy source that is capable of uniformly applying energy to the build material deposited on the support member 236 or 336. In some examples, the energy source 272 can include an array of energy sources.
在一些實例中,該能量源272被配置成本質上係以一均勻的方式施加能量至一建構材料層的該整個表面上。在這些實施例中,該能量源272可被稱為是一未聚焦的能量源。在這些實施例中,一整個層可以具有同時施加於其的能量,這可有助於提升一三維物件被產生的速度。 In some examples, the energy source 272 is configured to apply energy to the entire surface of a layer of build material in a uniform manner.

For example, the controller 210 can control the energy source to apply only energy to the portion of the build material to which the coalescing agent has been applied.
在另外的實例中,該能量源272可以是一聚焦的能量源,諸如一雷射光束。在這實例中,該雷射光束可以被控制來在一建構材料層的一整個或一部分上進行掃描。在這些實例中,該雷射光束可根據化劑遞送控制資料被控制來掃描過一建構材料層。舉例來說,該雷射光束可被控制以將能量施加到一層在其上聚結劑已被遞送至的那些部分。 In another example, the energy source 272 can be a focused source of energy, such as a laser beam. In this example, the laser beam can be controlled to scan over a whole or a portion of a layer of build material. In these examples, the laser beam can be controlled to scan a layer of build material based on the chemical delivery control data. For example, the laser beam can be controlled to apply energy to a portion of the layer to which the coalescing agent has been delivered.
在一些實例中,該系統200可以另外包括一加熱器或預加熱器來發射熱量以把被沉積在該支撐構件236上的建構材料保持在一預定的溫度範圍內。該加熱器可具有 一加熱單元陣列。該等加熱單元中的每一個可以是任何合適的加熱單元,舉例來說一加熱燈,諸如一紅外線燈。該配置可以被最佳化來在由該建構材料所展開的區域提供均勻的熱量分佈。每一個加熱單元,或加熱單元組,可具有一可調整的電流或電壓供給以可變地控制被施加到該建構材料表面上的該局部能量密度。 In some examples, the system 200 can additionally include a heater or pre-heater to emit heat to maintain the build material deposited on the support member 236 within a predetermined temperature range. The heater can have An array of heating cells. Each of the heating units can be any suitable heating unit, such as a heat lamp, such as an infrared lamp. This configuration can be optimized to provide a uniform heat distribution in the area unfolded by the build material. Each heating unit, or group of heating units, can have an adjustable current or voltage supply to variably control the local energy density applied to the surface of the building material.
圖4根據一些實例係一流程圖,其說明了產生了一三維物件的一種方法400。該方法可以是電腦實現的。在一些實例中,被展示出的順序可以改變,以使得一些步驟可以同時進行,也可以添加一些步驟,並且也可以省略一些步驟。在描述圖3時,將參考圖2a、2e、3、和5a-d。圖5a-d根據一些實例展示出一系列之建構材料層的橫截面側視圖。 4 is a flow diagram illustrating a method 400 of generating a three-dimensional object, in accordance with some examples. The method can be implemented by a computer. In some instances, the order shown may be changed such that some steps may be performed simultaneously, some steps may be added, and some steps may be omitted. In describing Figure 3, reference will be made to Figures 2a, 2e, 3, and 5a-d. Figures 5a-d show cross-sectional side views of a series of layers of construction material, according to some examples.
在402,該控制器210會獲取化劑遞送控制資料208。該化劑遞送控制資料208為將被產生之三維物件的每一個切片定義了在該建構材料上的該等部分或該等位置,如果有的話,聚結劑將被遞送至其處。該化劑遞送控制資料208可由在該系統200中或在其之外一合適的三維物件處理系統所產生。在一些實例中,該化劑遞送控制資料208的產生可基於物件設計資料,其代表一將被產生物件的一三維模型,和/或從代表該物件屬性的物件設計資料來產生。該模型可以定義該物件的該等實心部分,並且可由該三維物件處理系統進行處理以產生的該模型之平行平面的切片。每一個切片可定義建構材料之一各別層的一部分,其 將由該積層製造系統來固化。該物件屬性資料可定義該物件的屬性,諸如密度、表面粗糙度、強度、和類似物。 At 402, the controller 210 will acquire a chemical delivery control profile 208. The agent delivery control profile 208 defines each portion or locations of the three-dimensional article to be produced on the construction material, if any, to which the coalescing agent will be delivered. The agent delivery control profile 208 can be generated by a suitable three-dimensional object processing system in or external to the system 200. In some examples, the generation of the agent delivery control profile 208 can be based on object design data that represents a three-dimensional model of the object to be produced, and/or generated from object design data representative of the object's attributes. The model may define the solid portions of the object and may be processed by the three-dimensional object processing system to produce slices of parallel planes of the model. Each slice may define a portion of each of the layers of the construction material, It will be cured by the laminate manufacturing system. The object attribute data can define properties of the object, such as density, surface roughness, strength, and the like.
在404,在該建構模組214上的一電腦可讀取媒體可判定和/或儲存代表建構模組特徵的建構模組資料,諸如正被使用的建構材料類型,舉例來說基於使用者輸入或透過感測器檢測。該建構模組的其他特徵,諸如該建構模組的實體尺寸,可以被預先儲存在該電腦可讀取媒體上,如前面所討論的。 At 404, a computer readable medium on the construction module 214 can determine and/or store construction module data representative of the features of the construction module, such as the type of construction material being used, for example based on user input.

For example, the controller 210 can control the construction distributor 242 to provide the layer 276 on a previously completed layer 248 shown in Figures 2e and 4a. The completed layer 248 can include a cured portion 250. Although layer 248, which is completed for purposes of illustration, is illustrated in Figures 5a-d, it should be understood that the first layer 248 can be created initially by applying steps 408 through 412.
在一些實例中,諸如若該建構組件224被使用,該層276可被如下地遞送。參考圖2e和4a,在該建構材料腔226中的該支撐構件230可以由該活塞232在該z軸方向上以如此的一種方式被定位使得該儲存的建構材料246的一部分會延伸超出該建構組件224的該頂部邊緣。在該建構腔228中的該支撐構件236可以由該活塞236在該z軸方向上以 如此的一種方式被定位使得一預定的間隙被提供在建構材料的該先前已沉積層248的上方。該建構材料分配器242然後可以在該x軸方向上縱向地移動以滾動該儲存的建構材料246的該延伸部分進入該預定的間隙以在該建構腔228中產生該新的層276。該遞送可以基於被儲存在該建構模組的該電腦可讀取媒體中有關於該建構模組特徵的該資料和/或命令。 In some examples, such as if the construction component 224 is used, the layer 276 can be delivered as follows. Referring to Figures 2e and 4a, the support member 230 in the build material cavity 226 can be positioned by the piston 232 in the z-axis direction in such a manner that a portion of the stored build material 246 can extend beyond the construction. The top edge of component 224. The support member 236 in the construction chamber 228 can be by the piston 236 in the z-axis direction One such manner is positioned such that a predetermined gap is provided over the previously deposited layer 248 of build material. The build material dispenser 242 can then be moved longitudinally in the x-axis direction to roll the extended portion of the stored build material 246 into the predetermined gap to create the new layer 276 in the build cavity 228. The delivery may be based on the data and/or commands associated with the features of the construction module stored in the computer readable medium of the construction module.
在一些實例中,諸如若該建構組件324被使用,該層276可被如下地遞送。參考圖3和4a,在該建構材料腔326中的該支撐構件330可以由該活塞332在該z軸方向上一種方式被如此定位使得該儲存的建構材料246的一部分會延伸超出該建構組件324的該頂部邊緣。在該建構腔328中的該支撐構件336可以由該活塞336在該z軸方向上被如此定位使得一預定的間隙被提供在建構材料的該先前已沉積層248的上方。然後,該等建構材料分配器332、384、和342可以被使用來遞送該層276。該儲存的建構材料246可以沿著圖3中的該等箭頭移動並被滾動進入該預定的間隙以在該建構腔228中產生該新的層276。該遞送可以基於被儲存在該建構模組的該電腦可讀取媒體中有關於該建構模組特徵的該資料和/或命令。 In some examples, such as if the construction component 324 is used, the layer 276 can be delivered as follows. Referring to Figures 3 and 4a, the support member 330 in the build material cavity 326 can be positioned by the piston 332 in a manner in the z-axis direction such that a portion of the stored build material 246 can extend beyond the build component 324. The top edge of the. The support member 336 in the build chamber 328 can be positioned by the piston 336 in the z-axis direction such that a predetermined gap is provided over the previously deposited layer 248 of build material. The build material dispensers 332, 384, and 342 can then be used to deliver the layer 276. The stored build material 246 can be moved along the arrows in FIG. 3 and rolled into the predetermined gap to create the new layer 276 in the build cavity 228. The delivery may be based on the data and/or commands associated with the features of the construction module stored in the computer readable medium of the construction module.
在410,一聚結劑278可被選擇性地遞送至建構材料該層276的該表面上的一個或多個部分,如在5b圖中所示。該聚結劑278的該選擇性遞送可以該劑遞送控制資料208所定義的圖案被執行在該層276的各部分以變成固體來 形成正被產生之該三維物件的部分。「選擇性的遞送」係指聚結劑會以各種圖案被遞送至該建構材料的該表面層的選定部分。該圖案可以由該化劑遞送控制資料208來定義,並基於被儲存在該建構模組的該電腦可讀取媒體中有關於該建構模組特徵的該資料和/或命令。 At 410, a coalescing agent 278 can be selectively delivered to one or more portions of the surface of the layer 276 of construction material, as shown in Figure 5b. This selective delivery of the coalescent 278 can be performed at various portions of the layer 276 to become solid by a pattern defined by the agent delivery control profile 208. A portion of the three-dimensional object being produced is formed. "Selective delivery" means that the coalescing agent is delivered to selected portions of the surface layer of the building material in a variety of patterns. The pattern can be defined by the agent delivery control data 208 and based on the data and/or commands stored in the computer readable medium of the construction module regarding the features of the construction module.
圖5c展示出聚結劑278基本上已經完全滲透入建構材料的該層276,但在其他的實例中,滲透的程度可以小於100%。 Figure 5c shows that the coalescent 278 has substantially completely penetrated into the layer 276 of the build material, but in other examples, the degree of penetration can be less than 100%.
在412,一預定的能量水平會被暫時地施加至建構材料的該層276。在各種不同的實例中,該施加的能量可以是紅外線或近紅外線能量、微波能量、紫外(UV)光、鹵素光、超聲波能量、或類似物。能量的該臨時施加該會致使該建構材料在其上聚結劑278已被遞送或已經滲透的部分升溫超過該建構材料的熔點並進行聚結。在冷卻時,已聚結的該等部分變成為固體並形成該正被產生之三維物件的部分。如前面所討論的,一個如此的部分250可能已經在一先前的迭代中被產生。在能量的該施加過程中,所吸收的熱量可能會傳播到該先前已固化的部分250以致使部分250的部分會加熱到高於它的熔點。這種效果可有助於產生一部分280其在已固化的建構材料的相鄰層之間具有強的層間粘合,如在圖5d中所示。 At 412, a predetermined energy level is temporarily applied to the layer 276 of build material. In various examples, the applied energy can be infrared or near infrared energy, microwave energy, ultraviolet (UV) light, halogen light, ultrasonic energy, or the like. This temporary application of energy causes the building material to warm up above the melting point of the building material and coalesce on the portion of the building material on which the coalescent 278 has been delivered or has penetrated. Upon cooling, the agglomerated portions become solid and form part of the three-dimensional object being produced. As discussed previously, one such portion 250 may have been generated in a previous iteration. During this application of energy, the absorbed heat may propagate to the previously cured portion 250 such that portions of portion 250 will heat above its melting point. This effect can help create a portion 280 that has strong interlayer adhesion between adjacent layers of cured build material, as shown in Figure 5d.
在一建構材料層已經如上述那樣子的被處理之後,可以在建構材料的該先前已處理層的上方提供建構材料的新層。透過這種方式,建構材料之該先前已處理的層 會充當建構材料層之一隨後層的一支撐體。方塊408到412的該處理過程然後可被重複以一層一層地產生一三維物件。 After a layer of build material has been processed as described above, a new layer of build material can be provided over the previously treated layer of build material. In this way, the previously processed layer of material is constructed Will act as a support for the subsequent layers of one of the building material layers. The process of blocks 408 through 412 can then be repeated to produce a three-dimensional object layer by layer.
此外,在方塊408至412期間中的任何時候,額外的建構模組214可以由該系統200來接收諸如在方塊406。因此,雖然該方法400是透過方塊408至412進行迭代,但該方法400的一平行實例可以繼續進行,使得該系統200一次可以在不同的建構模組214中不同的三維物件上執行多個列印作業。在其他的實例中,在該方法400的該第一實例已經完成和產生一三維物件之後,該方法400的該第二實例可馬上繼續進行方塊408至412,使得該第二三維物件會在該第一個被完成之後立即被產生,在其之間的時間延遲會很少或根本沒有。 Moreover, at any time during the period of blocks 408 through 412, an additional construction module 214 can be received by the system 200, such as at block 406. Thus, while the method 400 is iterative through blocks 408 through 412, a parallel instance of the method 400 can continue such that the system 200 can execute multiple columns on different three-dimensional objects in different building blocks 214 at a time. Print jobs. In other examples, after the first instance of the method 400 has completed and generated a three-dimensional object, the second instance of the method 400 may proceed to blocks 408-412 immediately so that the second three-dimensional object will be in the The first one is generated immediately after it is completed, with little or no time delay between them.
此外,在一些實例中,在產生三維物件的過程中即使建構模組214需要清理或重新填充,有可能還是幾乎沒有或沒有時間延遲。舉例來說,如果一建構模組214需要被清理或重新填充,該建構模組214可以從該系統200被移除,同時該系統200會繼續在其他建構模組214中產生其他的三維物件。另外,該建構模組214的該設計,舉例來說它全功能的建構系統在圖2d-e中包括馬達234和240或在圖3中包括馬達334、340、344、和344,可讓該建構模組214能夠被快速和容易地清理。舉例來說,該殼體216可有助於不讓建構材料逸出到在該建構模組214中不希望的地方。此外,該建構模組214可被插入至一清理裝置中,其可以是, 舉例來說,自動清理該建構模組214的該等部分,同時馬達正在運行使得該建構材料可以從該建構模組214的該等組件處搖出。在一些實例中,在清理中的手動步驟也可被執行,舉例來說當馬達正在運行時。 Moreover, in some instances, even if the building module 214 needs to be cleaned or refilled during the creation of a three-dimensional object, there may be little or no time delay. For example, if a construction module 214 needs to be cleaned or refilled, the construction module 214 can be removed from the system 200 while the system 200 continues to produce other three-dimensional objects in the other construction modules 214. Additionally, the design of the construction module 214, for example, its fully functional construction system includes motors 234 and 240 in Figures 2d-e or motors 334, 340, 344, and 344 in Figure 3, The building block 214 can be cleaned quickly and easily. For example, the housing 216 can help prevent construction material from escaping into an undesired location in the building block 214. In addition, the construction module 214 can be inserted into a cleaning device, which can be, For example, the portions of the construction module 214 are automatically cleaned while the motor is running such that the build material can be shaken from the components of the construction module 214. In some instances, manual steps in cleaning can also be performed, for example when the motor is running.
