具体实施方式
为使本发明更加明确详实，兹列举较佳实施例并配合下列图示，将本发明的结构及其技术特征详述如后；其中在图式中各部件的尺寸并非依实际比例绘示。
参考第1图-第10图所示，本发明提供一种网状椅面1及其制造方法以及具有网状椅面的椅具，其中该网状椅面1包含一椅面框架10及至少一PU网面单元30。
该椅面框架10以一椅面材料制成而形成一具有椅面形状的框架体，现有的椅面材料包含金属、塑胶、木头等但不限制；该椅面框架10系能凭借其他结构件或锁固装置而组装在一椅具3上以成为该椅具3结构体的一部分如椅背部分或椅座部分但不限制，该椅面框架10具有一外框部11。
此外，该椅面框架10也可利用该3D打印装置2并以聚氨酯(PU)31作为打印材但不限制，使该椅面框架10进一步能凭借该3D打印装置2的喷头40喷出聚氨酯(PU)31以打印成型如图3、图4、图7、图8所示。
该至少一PU网面单元30利用至少一3D打印装置2且以聚氨酯(PU)31作为该3D打印装置2的打印材，而凭借该3D打印装置2的喷头40喷出聚氨酯(PU)31以在该椅面框架10的外框部11的一表面11a上及一相配合的支撑件20的一支撑面21上打印成型，并使该至少一PU网面单元30在打印成型时能与该椅面框架10的外框部11结合成一体。
该支撑件20可视为该3D打印装置2在进行打印工作时所用的辅助治具，该支撑件20可装卸地装设于该椅面框架10的结构体中，该支撑件20的主要作用是使该椅面框架10的外框部11的一表面11a能与该支撑件20的一支撑面21保持或形成一平顺面，例如该支撑件20可装卸地安装于该椅面框架10内如填塞在该外框部11的一中空空间14中如图2-图4、图6-图8所示但不限制，如此该3D打印装置2的喷头40能在所形成的平顺面(11a，21)上顺利地进行打印工作。当该至少一PU网面单元30打印并一体成型于该椅面框架10上时，该支撑件20即可自该椅面半成品10内移除如图1、图5、图9、图10所示。
该聚氨酯(PU)31包含：二液型PU(two components PU)、湿气硬化单液型PU(moisture curable one component PU)、热塑型PU(TPU，thermoplastic PU)但不限制。
如图3、图7所示，当该聚氨酯(PU)31是以二液型聚氨酯(PU)31a作为打印材时，其中该二液型聚氨酯(PU)31a的第一液32及第二液33被分别以输送管41送至一设在该3D打印装置2的喷头40之前的一容室42中以进行均匀混合，再使均匀混合后的二液型PU31a在混合硬化之前由喷头40喷出以进行打印工作如图4、图8所示。此外，针对传统二液型PU会有扩散的问题，可在该传统二液型PU中添加流动控制添加剂来解决该问题。
如图1、图5所示，当该至少一PU网面单元30在进行打印工作时，可进一步在该至少一PU网面单元30上打印形成至少一装饰图案34但不限制，如此可提升该至少一PU网面单元30的图案的多样化，并增加消费者的选择性。
该椅面框架10的外框部11上进一步设有多个固定孔12，该多个固定孔12以等距排列方式(如图5所示)或非等距排列方式(如图1所示)设在该外框部11上，使该至少一PU网面单元30的外缘能在打印成型时一体延伸打印并进入该多个固定孔12内，用以使该至少一PU网面单元30能固定在该椅面框架10的外框部11上并连结成一体，如此相对节省该至少一PU网面单元30与该椅面框架10的外框部11之间的结合作业程序。
如图6所示，该椅面框架10的外框部11上进一步设有多个凹槽13，该多个凹槽13以等距或非等距的排列方式(但不限制)设在该外框部11上，如此使该至少一PU网面单元30的外缘在打印成型时能一体延伸打印在该多个凹槽13内，用以使该至少一PU网面单元30能固定在该椅面框架10的外框部11上并连结成一体，如此相对节省该至少一PU网面单元30与该椅面框架10的外框 部11之间的结合作业程序。
此外，该网状椅面1应用作为该椅具的椅背(如图1、10所示)或椅座(图未示)使用但不限制，其中该椅面框架10的外框部11的形状随该椅子的椅背或椅座的外形来配合设计，其中该支撑件20的表面随该椅面框架10的外框部11的外形来配合设计。
本发明的网状椅面的制造方法，包含下列步骤：
步骤S1：提供一椅面框架10，并在该椅面框架10内安装一支撑件20以使该椅面框架10的外框部11的一表面能与该支撑件20的表面形成一平顺面。
步骤S2：利用至少一3D打印装置2且以聚氨酯(PU)31作为打印材。
步骤S3：利用该3D打印装置2的喷头40，以3D打印方式在该椅面框架10的一外框部11的一表面11a上及该支撑件20的支撑面21上打印成型出至少一PU网面单元30。
步骤S4：再对该至少一PU网面单元30进行硬化。
步骤S5：将该支撑件20自该椅面框架10内移除，即完成一网状椅面1。
本发明网状椅面1及其制造方法以及具有网状椅面的椅具，与同领域现有相关技术比较，具有以下优点：
(1)本发明的网状椅面1凭借3D打印技术以直接在该椅面框架10上打印成型一可多样化设计的PU网面单元30，有利于该网状椅面1的量产化及市场竞争力。
(2)本发明的网状椅面1进一步可使该至少一PU网面单元30在3D打印成型同时与该椅面框架10的外框部11结合成一体，如此能节省该至少一PU网面单元30与该椅面框架10的外框部11之间的结合作业程序。
(3)当在3D打印成型该至少一PU网面单元30时，可依需要而同时在该至少一PU网面单元30打印成型至少一装饰图案34，以提升该至少一PU网面单元30的图案的多样化，并增加消费者的选择性。
以上说明对本发明而言只是说明性的，而非限制性的，本领域普通技术人员理解，在不脱离权利要求所限定的精神和范围的情况下，可作出许多修改、变化或等效，但都将落入本发明的保护范围之内。
