鍍層及具有鍍層之樹脂槽Plating and resin bath with plating
本發明係有關一種鍍層及具有鍍層之樹脂槽，尤指一種兼具可提高光照固化物體之加工良率、易於實施，與披覆式應用範圍廣之鍍層及具有鍍層之樹脂槽。The invention relates to a plating layer and a resin groove having a plating layer, in particular to a plating layer and a resin groove having a plating layer which can improve the processing yield of the light-cured object, is easy to implement, and has a wide application range.
參閱第5圖，傳統之下照式三維列印設備主要包括：一樹脂槽80A，一成形板80B，一驅動部80C及一下照式光源80D。其中，該樹脂槽80A係具有一透光底面801，並用以容納預定量之樹脂802。該成形板80B係可被該驅動部80C帶動而移動；該下照式光源80D係用以由下而上，朝該透光底板801發出一光線803(如第6圖所示)，該光線803係穿透該透光底面801，而朝向該成形板80B照射，使得被照到之該樹脂802固化成形於該成形板80B。當然，也可在該光源803上加上一光罩(公知技術，圖面未示，合先陳明)，使得只有對應光罩之特定形狀或樣式的樹脂802，才會被照到而固化成形。 更詳細的講，其光照固化成形之基本步驟包括： [1] 將成形板移至預定位置進行第一層之製作。該驅動部80C控制該成形板80B移至距離該透光底面801一單層厚度d之位置。 [2] 發出光線進行固化。此時該下照式光源80D係由下而上發出光線803，其穿透該透光底面801而朝向該成形板80B照射，經一成形時間後，使得被照到之該樹脂802因為此光線803而固化，該成形板80B之底面會形成一固化之樹脂層81(如第6圖所示，即第一層之製作)。 [3] 成形板上移以進行第二層之製作。該驅動部80C控制此成形板80B(連同第一層之固化之該樹脂層81)再上移一單層厚度d之位置。液狀之樹脂802會流入此固化之該樹脂層81與該透光底面801之間(如第7圖所示)。 重覆前述[2]之步驟即完成第二層之固化，依此原理再不斷重複即可完成N層之該樹脂層81，在此不贅述。 然而，當進行成形板上移脫離之步驟(即第[3]步驟)時，會發生下列問題。亦即，剛性之該成形板80B在上移時，是硬生生的將固化之樹脂層81拉離該透光底面801，此時非常容易造成固化之樹脂層81破裂。 因此，目前業界有許多方法來解決。 第一種傳統改善方案是在原先預定面對該樹脂層81之該透光底面801上，設置一第一隔層91(如第8圖所示)，該第一隔層91係為聚二甲基矽氧烷(Polydimethylsiloxane，簡稱PDMS)，由於具有高透光性及(高)彈性，因此，可以稍為改善前述樹脂層破裂之問題。然而，使用一段時間後，由於樹脂802在固化時產生熱，此熱會逐漸導致此由PDMS製成之該第一隔層91白化(即透光性變差)。另外，每一次脫離時之會產生拉力，使用一段時間後逐漸導致第一隔層91破裂，整體上第一種傳統改善方案之使用壽命仍然有限。 第二種傳統改善方案是在第一種傳統改善方案之該第一隔層91上再設置一第二隔層92(如第9圖所示)。此第二隔層92是由鐵弗龍(聚四氟乙烯，英文全名為Polytetrafluoroethylene，簡稱PTFE，一般俗稱Teflon)。加上此第二隔層92後，雖然可以阻隔一些熱傳遞，但第二種傳統改善方案之使用壽命只比第一種傳統改善方案稍好，仍然有改善的空間。 第三種傳統改善方案是在第一種傳統改善方案之該成形板80B修改成旋轉及上移來脫離(如第10圖所示)。然而，此種作法導致該驅動部80C(第10圖中未示意該驅動部80C，合先陳明)之控制及設計更為複雜，同時，旋轉脫離時位於旋轉中心及外圍之受力不同，有時仍會造成固化之該樹脂層破裂。 第四種傳統改善方案是在第三種傳統改善方案之成形板80B修改成水平橫移脫離(再拉抬上移)，如第11圖所示。然而，此種作法不僅該驅動部80C(第11圖中未示意該驅動部80C，合先陳明)之控制及設計更為複雜，同時，該樹脂槽80A之空間可能有增大為原有的兩倍寬度或更大，使得所需之樹脂量也倍增，又，橫移脫離時也有可能會造成固化之樹脂層破裂。 第五種傳統改善方案將該樹脂槽中央部份挖空成為一貫穿開口，其上設一鐵弗龍薄膜93，如第12圖所示。然而，此鐵弗龍薄膜93在使用一段時間後容易變皺，當承載樹脂時，會變成略為鬆垮之弧狀(如虛線所示，此為示意)，此時將導致固化之樹脂層產生厚度不均之問題。 第六種傳統改善方案將該樹脂槽中央部份挖空成為一貫穿開口，樹脂槽底面設該鐵弗龍薄膜93(並被一夾板固定)，其底下設一玻璃層94來支撐，如第13圖所示。然而，第六種傳統改善方案雖然多了玻璃層94來支撐，仍然有改善的空間。 有鑑於此，必需研發出可解決上述習用缺點之技術。Referring to FIG. 5, the conventional down-lit three-dimensional printing apparatus mainly comprises a resin tank 80A, a forming plate 80B, a driving portion 80C and a down-light source 80D. The resin tank 80A has a transparent bottom surface 801 for accommodating a predetermined amount of resin 802. The forming plate 80B can be moved by the driving portion 80C; the downlighting light source 80D is configured to emit a light 803 (shown in FIG. 6) from the bottom to the transparent substrate 801. The 803 penetrates the light-transmissive bottom surface 801 and is irradiated toward the forming plate 80B so that the resin 802 to be cured is solidified and formed on the forming plate 80B. Of course, a light mask (known in the art, not shown in the drawings) can be added to the light source 803, so that only the resin 802 corresponding to the specific shape or pattern of the mask can be cured and cured. Forming. In more detail, the basic steps of the light curing forming include: [1] Moving the forming plate to a predetermined position for the first layer. The driving portion 80C controls the forming plate 80B to move to a position a single layer thickness d from the light transmitting bottom surface 801. [2] Light is emitted for curing. At this time, the downlighting light source 80D emits light 803 from the bottom up, which penetrates the transparent bottom surface 801 and is irradiated toward the forming plate 80B. After a forming time, the resin 802 is irradiated because of the light. Curing with 803, a solidified resin layer 81 is formed on the bottom surface of the forming plate 80B (as shown in Fig. 6, that is, the first layer is produced). [3] The forming plate is moved to make the second layer. The driving portion 80C controls the forming plate 80B (along with the cured resin layer 81 of the first layer) to be moved up to a position of a single layer thickness d. The liquid resin 802 flows between the cured resin layer 81 and the light transmissive bottom surface 801 (as shown in Fig. 7). The curing of the second layer is completed by repeating the steps of the above [2], and the resin layer 81 of the N layer is completed by repeating the principle according to this principle, and details are not described herein. However, when the step of removing the forming plate (i.e., step [3]) is performed, the following problems occur. That is, when the rigid shaped plate 80B is moved up, the hardened resin layer 81 is pulled away from the light-transmitting bottom surface 801, and the cured resin layer 81 is easily broken. Therefore, there are many ways to solve this problem in the industry. The first conventional improvement solution is to provide a first spacer 91 (shown in FIG. 8) on the transparent bottom surface 801 originally intended to face the resin layer 81. The first spacer 91 is a poly layer. Since polydimethylsiloxane (PDMS) has high light transmittance and (high) elasticity, the problem of cracking of the above resin layer can be slightly improved. However, after a period of use, since the resin 802 generates heat upon curing, this heat gradually causes the first barrier layer 91 made of PDMS to be whitened (i.e., the light transmittance is deteriorated). In addition, each time the detachment occurs, a pulling force is generated, and after a period of use, the first barrier layer 91 is gradually broken, and the service life of the first conventional improvement scheme as a whole is still limited. A second conventional improvement is to provide a second barrier 92 (as shown in Figure 9) on the first barrier 91 of the first conventional improvement. The second compartment 92 is made of Teflon (polytetrafluoroethylene, English full name Polytetrafluoroethylene, referred to as PTFE, commonly known as Teflon). With the addition of this second compartment 92, although some heat transfer can be blocked, the service life of the second conventional improvement scheme is only slightly better than that of the first conventional improvement scheme, and there is still room for improvement. A third conventional improvement is that the forming plate 80B of the first conventional improvement is modified to be rotated and moved up to disengage (as shown in Fig. 10). However, such a method causes the control and design of the driving portion 80C (not shown in FIG. 10), and the control and design of the driving portion 80C are more complicated. At the same time, the force at the center of rotation and the periphery of the rotation is different. Sometimes the cured resin layer is broken. The fourth conventional improvement is to modify the forming plate 80B of the third conventional improvement to horizontal traverse (re-lifting up), as shown in FIG. However, this method is not only complicated in the control and design of the driving portion 80C (the driving portion 80C is not illustrated in FIG. 11), but the space of the resin groove 80A may be increased to the original. The double width or larger doubles the amount of resin required, and it is also possible that the cured resin layer is broken when traversed. A fifth conventional improvement scheme hollows out the central portion of the resin tank into a through opening having a Teflon film 93 thereon as shown in Fig. 12. However, the Teflon film 93 is easily wrinkled after being used for a period of time, and when it is loaded with a resin, it becomes a slightly loose arc (as indicated by a broken line, this is an illustration), which causes a cured resin layer to be produced. The problem of uneven thickness. The sixth conventional improvement scheme hollows out the central portion of the resin tank into a through opening, and the bottom surface of the resin tank is provided with the Teflon film 93 (and is fixed by a splint), and a glass layer 94 is arranged under the support, as in the first Figure 13 shows. However, the sixth conventional improvement scheme, although supported by the glass layer 94, still has room for improvement. In view of this, it is necessary to develop a technique that can solve the above disadvantages.

In particular, the problem to be solved by the present invention is that conventional three-dimensional printing often causes the problem of tearing of the finished product. The technical means for solving the above problems is to provide a plating layer and a resin tank having a plating layer, comprising: relating to the plating layer, comprising: one unit weight of polydimethyl methoxyoxane; and one graphene having a weight of the foregoing poly 2 The methyloxane is between 1.5 and 2.5 per thousand.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the preferred embodiments illustrated herein. The invention will be described in detail in the following examples in conjunction with the drawings:
參閱第1圖，本發明係為一鍍層及具有鍍層之樹脂槽。 關於該鍍層10，係由下列成份混合而成： 一單位重量之聚二甲基矽氧烷(Polydimethylsiloxane，簡稱PDMS)。 一石墨烯，其重量係為前述該聚二甲基矽氧烷之千分之1.5至千分之2.5。 藉此，構成具有耐拉(如第4圖所示之第一曲線L1)、(高)彈性、疏水性、不白化性及透光特性之該鍍層10。 實務上，該一單位重量之聚二甲基矽氧烷可呈流體狀； 該石墨烯可為微粒狀； 藉此，流體狀之該聚二甲基矽氧烷與微粒狀之該石墨烯係利於混合。 流體狀之特性，利於該鍍層10進行流動分佈以及乾涸後披覆成形，而構成本案之具有鍍層的樹脂槽。 關於該具有鍍層的樹脂槽，係包括鍍層10及一樹脂槽結構20。 關於該樹脂槽結構20，係具有一透光底面21，並用以容納一樹脂802，該鍍層10係用以披覆於該透光底面21其面對該樹脂802的位置。 藉此，使該透光底面21用以朝向該樹脂802進行光照固化作業時，具有耐拉(如第4圖所示之第一曲線L1)、(高)彈性、疏水性及透光特性。 實務上，該具有鍍層之樹脂槽係可應用於下照式三維列印設備(如第1圖所示)，且又包括一成形板30、一驅動部40及一下照式光源50。 其進行光照固化成形之三維列印步驟包括: [1] 將成形板移至預定位置進行第一層之製作。參閱第1圖，透過該驅動部40，控制該成形板30移至距離該透光底面21一單層厚度d之位置。 [2] 發出光源進形固化。此時該下照式光源50係由下而上，朝該透光底面21發出一光線51，該光線51穿透該透光底面21及該鍍層10，而朝該成形板30照射，經一成形時間後，被照到之該樹脂802係於該成形板30之底面形成一固化之樹脂層81(第2圖所示，即第一層之製作)。 [3] 成形板上移以進行第二層之製作。透過該驅動部40控制該成形板30(連同第一層之固化之樹脂層81)再上移至一單層厚度d之位置。液狀之該樹脂802會流入此固化之樹脂層81與該鍍層10之間(如第3圖所示)。 重覆前述[2]之步驟即完成該樹脂層81之第二層的固化作業，依此原理再不斷重複即可完成N層之該樹脂層81的結構，在此不贅述。 重點在於，由於該鍍層10同時具有耐拉(如第4圖所示之第一曲線L1)、(高)彈性、疏水性、不白化性及透光特性。因疏水性的特性，使該樹脂層81不會牢牢黏固於該鍍層10上，當進行『[2]成形板上移脫離之步驟』時，剛性之該成形板30在上移時，藉由該鍍層10之(高)彈性，可於該樹脂層81(固化)與該透光底面21(硬)之間作為彈性緩衝，而可慢慢的拉開(耐拉)，可提高該樹脂層81被拉開時的完整性及良率。樹脂固化過程產生熱會造成PDMS逐漸白化，但本發明不會受到熱影響而白化。 如第4圖所示，從該第一曲線L1(代表該鍍層10)與該第二曲線L2(代表傳統三維列印設備之樹脂槽的透光底面)可明確比較出，該第一曲線L1之伸長量為800%，而該第二曲線L2只有大約540%(少了快一倍)，至於該第一曲線L1之拉伸強度幾乎達到3.8 MPa，然而該第二曲線L2則只有大約0.5Mpa。 本發明之優點及功效係如下所述： [1] 可提高光照固化物體之加工良率。本發明之該鍍層同時具有耐拉、(高)彈性、疏水性、不白化性及透光特性。使得光照固化成形的樹脂層不會牢牢黏固於該鍍層上，而成形板上移時，則可藉由該鍍層之(高)彈性及耐拉力，可於該樹脂層(固化)與該透光底面(硬)之間作為彈性緩衝，而可慢慢的拉開，提高該樹脂層(光照固化結構)被拉開時的完整性及良率。故，可提高光照固化物體之加工良率。 [2] 易於實施。該鍍層主要為流體狀之聚二甲基矽氧烷與微粒狀之石墨烯混合而成，全為目前公知之化學成份，無需另行尋找化學配方。故，易於實施。 [3] 披覆式應用範圍廣。本發明之鍍層為披覆式，只要可披覆的領域均可應用。故，披覆式應用範圍廣。 以上僅是藉由較佳實施例詳細說明本發明，對於該實施例所做的任何簡單修改與變化，皆不脫離本發明之精神與範圍。Referring to Fig. 1, the present invention is a plating layer and a resin bath having a plating layer. The plating layer 10 is obtained by mixing the following components: One unit weight of polydimethylsiloxane (PDMS). A graphene having a weight of 1.5 to 2.5 per thousand of the aforementioned polydimethyl siloxane. Thereby, the plating layer 10 having the tensile resistance (the first curve L1 shown in FIG. 4), the (high) elasticity, the hydrophobicity, the non-whitening property, and the light transmission property is formed. In practice, the one unit weight of the polydimethyloxane may be in the form of a fluid; the graphene may be in the form of particles; thereby, the polydimethylsiloxane and the particulate form of the graphene are in a fluid form. Conducive to mixing. The fluid-like property facilitates the flow distribution of the plating layer 10 and the dry-coating and forming, and constitutes a resin bath having a plating layer in the present invention. The resin bath having a plating layer includes a plating layer 10 and a resin tank structure 20. The resin tank structure 20 has a light-transmissive bottom surface 21 for receiving a resin 802 for covering the transparent bottom surface 21 at a position facing the resin 802. Thereby, when the light-transmitting bottom surface 21 is used for the light curing operation toward the resin 802, it has tensile strength (such as the first curve L1 shown in FIG. 4), (high) elasticity, hydrophobicity, and light transmission characteristics. In practice, the coated resin tank can be applied to a down-illuminated three-dimensional printing apparatus (as shown in FIG. 1), and further includes a forming plate 30, a driving portion 40, and a down-light source 50. The three-dimensional printing step of performing light curing forming includes: [1] moving the forming plate to a predetermined position for making the first layer. Referring to Fig. 1, the forming plate 30 is controlled to move to a position of a single layer thickness d from the light transmitting bottom surface 21 through the driving portion 40. [2] The light source is solidified. At this time, the downlight source 50 is from bottom to top, and a light 51 is emitted toward the transparent bottom surface 21. The light 51 penetrates the transparent bottom surface 21 and the plating layer 10, and is irradiated toward the forming plate 30. After the molding time, the resin 802 to be irradiated is formed on the bottom surface of the forming plate 30 to form a cured resin layer 81 (shown in Fig. 2, that is, the first layer). [3] The forming plate is moved to make the second layer. The forming plate 30 (along with the cured resin layer 81 of the first layer) is controlled by the driving portion 40 to be moved up to a position of a single layer thickness d. The liquid resin 802 flows between the cured resin layer 81 and the plating layer 10 (as shown in Fig. 3). The step of the above [2] is repeated to complete the curing operation of the second layer of the resin layer 81, and the structure of the resin layer 81 of the N layer can be completed by repeating the principle, and will not be described herein. The important point is that the plating layer 10 has both tensile resistance (such as the first curve L1 shown in FIG. 4), (high) elasticity, hydrophobicity, non-whitening property, and light transmission characteristics. Due to the hydrophobic property, the resin layer 81 is not firmly adhered to the plating layer 10, and when the [2] forming step of the forming plate is removed, when the rigid forming plate 30 is moved up, By virtue of the (high) elasticity of the plating layer 10, it can be elastically buffered between the resin layer 81 (cured) and the light-transmitting bottom surface 21 (hard), and can be slowly pulled (tension-resistant), which can be improved. The integrity and yield of the resin layer 81 when it is pulled apart. The heat generated during the curing of the resin causes the PDMS to gradually whiten, but the present invention is not whitened by heat. As shown in FIG. 4, the first curve L1 (representing the plating layer 10) and the second curve L2 (representing the light-transmitting bottom surface of the resin groove of the conventional three-dimensional printing apparatus) can be clearly compared, the first curve L1 The elongation is 800%, and the second curve L2 is only about 540% (less than twice as fast), as the tensile strength of the first curve L1 is almost 3.8 MPa, whereas the second curve L2 is only about 0.5. Mpa. The advantages and effects of the present invention are as follows: [1] The processing yield of the light-cured object can be improved. The coating of the present invention has both tensile resistance, (high) elasticity, hydrophobicity, non-whitening properties and light transmission properties. The resin layer formed by the light curing is not firmly adhered to the plating layer, and when the forming plate is moved, the resin layer (curing) and the resin layer can be cured by the (high) elasticity and the tensile strength of the plating layer. The light-transmissive bottom surface (hard) acts as an elastic buffer, and can be slowly pulled apart to improve the integrity and yield of the resin layer (light-cured structure) when it is pulled apart. Therefore, the processing yield of the light-cured object can be improved. [2] Easy to implement. The coating is mainly composed of a mixture of fluid polydimethyl siloxane and particulate graphene, all of which are currently known chemical components, without the need to find another chemical formula. Therefore, it is easy to implement. [3] A wide range of applications. The coating of the present invention is of a drape type and can be applied as long as it can be coated. Therefore, the coverage of the application is wide. The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
