与本发明的一个实施方案有关的3D打印机1包括喷嘴组合件10。
参照图1和图2，与本发明的一个实施方案有关的3D打印机1包括喷嘴组合件10、布置成向喷嘴组合件10供应墨的墨供应部30、用于移动喷嘴组合件10的转移部50和用于向喷嘴组合件10供应电源的电源供应部40。另外，3D打印机1包括用于分别控制喷嘴组合件10、供墨流量、电源供应部40和转移部50的控制部20。此外，3D打印机1可以包括从喷嘴组合件10喷射的墨置于其上的基部2。
喷嘴组合件10包括壳体15、喷嘴11、第一线圈12、第二线圈14和提起部13。
另外，墨供应部30可以连接至喷嘴组合件10的喷嘴11，并且墨可以储存在墨供应部30中。此外，墨可以包含纳米磁性材料，其中纳米磁性材料可以包括金属颗粒、金属氧化物或合金颗粒。例如，墨还可以为热固性树脂墨或热固性陶瓷墨。此外，热固性树脂墨可以具有50000cp至150000cp的粘度，并且可以包含5重量％的纳米磁性材料。此外，热固性陶瓷墨可以具有5000cp至50000cp的粘度，并且可以包含5重量％的纳米磁性材料和40重量％至80重量％的氧化铝颗粒。
参照图1，喷嘴组合件10包括壳体15、布置在壳体15中并连接至墨供应部30的喷嘴11、和布置在壳体15中的用于在由电源供应部40施加电源时产生磁场的第一线圈12。另外，喷嘴组合件10包括第二线圈14，所述第二线圈布置在壳体15中，布置成围绕喷嘴11和第一线圈12并在施加电源时产生磁场，条件是磁场有效区域和磁场强度中的至少一者不同于第一线圈12。此外，喷嘴组合件10包括提起部13，所述提起部用于分别提起喷嘴11、第一线圈12和第二线圈14以定位在壳体15中或暴露于壳体15的外部。
第二线圈14可以设置成使得磁场有效区域和磁场强度中的至少一者大于第一线圈12的磁场有效区域和磁场强度中的至少一者。另外，第二线圈14的长度和直径可以大于第一线圈12的长度和直径。
第一线圈12和第二线圈14可以设置成在安置在基部2上的墨S上形成交流电磁场(聚焦电磁场)。另外，第一线圈12和第二线圈14可以各自包括一个或更多个线圈结构。在此，线圈结构可以具有各种结构，例如圆形、多边形和螺旋形。此外，可以不同地确定线圈结构的形状和数量以及线圈结构之间的布置。例如，线圈结构可以具有圆柱形或螺旋形。此外，线圈结构可以具有圆形或矩形线圈形状。
另外，在喷嘴组合件10中，在操作之前所有的喷嘴11以及第一线圈12和第二线圈14均处于位于壳体15内的状态，当喷嘴11以及第一线圈12和第二线圈14中的至少一者暴露于壳体15的外部以进行操作时，其余的位于壳体15内。即，墨的喷射和墨的固化分别通过喷嘴11以及第一线圈12和第二线圈14在暴露于壳体15的外部的状态下进行。
具体地，控制部20执行喷嘴组合件的控制，其中控制部20可以控制使得当喷嘴11暴露于壳体15的外部时墨被喷射至外部以及当第一线圈12暴露于壳体15的外部时向第一线圈12供应电源。另外，控制部20可以设置成当第一线圈12暴露于壳体15的外部时使喷嘴11和第二线圈14定位在壳体15中。此外，控制部20可以设置成当第二线圈14暴露于壳体15的外部时使喷嘴11和第一线圈12定位在壳体中。此外，控制部20设置成使得当向第一线圈12和第二线圈14中的一个线圈供应电源时，不向另一个线圈供应电源。
另外，控制部20可以设置成调节施加至第一线圈12和第二线圈14的电流的强度、供应时间和频率。
此外，控制部20设置成使得墨S通过喷嘴11喷射至基部2侧，首先通过第一线圈12向墨S施加磁场，其次通过第二线圈14向墨施加磁场。
第一线圈12执行墨的初级固化(预固化)，第二线圈14执行经初级固化的墨的二次固化。
另一方面，第二线圈14是比第一线圈12相对更大的线圈，其在形成精细图案期间(在将结构层合至一定程度之后)或在层合完成之后开始操作，并执行施加磁场以整体上变为目标固化的功能。另外，参照图5，预固化意指墨的组分不完全固化但是图案不塌陷并保持恒定的程度的固化。在图5中，S1表示已通过第一线圈12预固化的墨，S2表示未预固化的墨。此外，当层合达到预固化状态时，活性化残留在层合界面中，使得在通过
第二线圈进行二次固化时，与单个线圈的完全固化相比接触表面处的强度特性得到改善。另一方面，在图6中，S3表示已完成预固化的墨。
例如，第一线圈12可以用于使结构的窄区域固化，其中磁场的强度可以为1mT至40mT，磁场有效区域可以为10μm至500μm。另外，第二线圈14可以用于使结构的大区域固化，其中磁场的强度可以为30mT至200mT，磁场有效区域可以为10mm至1000mm。
另外，转移部50可以使喷嘴组合件10在各种轴方向(x轴、y轴、z轴)上移动，并且可以设置成使得调节基部2与喷嘴组合件10之间的间隙。例如，喷嘴组合件10可以设置成相对于基部2可上下移动。
此外，电源供应部40可以分别向第一线圈12和第二线圈14供应例如频率为100kHz至1GHz且电流为5A至500A的电源。此外，电源供应部40可以向第一线圈12和第二线圈14供应具有不同强度的电源以产生不同强度的磁场。
此外，图3示出了在水平方向上切割图1所示的喷嘴组合件10的状态的截面形状，其中喷嘴组合件10也可以设置有单个喷嘴11或复数个喷嘴11-1、11-2。
如上所述的本发明的优选实施方案是出于示例性目的而公开的，其中具有本发明的普通知识的本领域技术人员可以在本发明的思想和范围内做出各种修正、修改和添加，并且这样的修正、修改和添加应被视为落入所附权利要求的范围内。
工业适用性
与本发明的至少一个实施方案有关的喷嘴组合件和包括其的3D打印机可以有效地进行打印、预固化和固化过程。
