Description

一种3D打印耗材及其应用 技术领域
本发明涉及3D打印领域，特别涉及一种3D打印耗材及其应用。
背景技术
3D打印技术是一种革命性的工业成型技术，原材料经过3D打印机便能直接成型，它是一种数字模型文件为基础，运用粉末状金属或塑料等可粘合材料，通过逐层打印的方式来构造物体的技术，不需经过模具的制造，节省了模具制造的时间及成本，随着3D打印技术的迅速发展，其对材料的要求也迅速提高，现有的3D打印耗材主要PLA塑料(聚乳酸)、ABS、nylon618、PVA等。目前，市面上的3D打印线材以实芯塑料为主，在打印过程中，线材的直径、尺寸、轨迹、体积等相关参数误差太大，很容易造成打印失败。另外，3D打印线材的冷却成型过程中，外部形状属于自由状态，外径、尺寸和形状波动大，只有通过水槽的温度控制状态，影响打印效果。
发明内容
鉴于上述问题，本发明的目的在于提供一种打印效率高，应用灵活和广泛的3D打印耗材及其应用。
为实现上述目的，本发明提供的一种3D打印耗材，其中,包括3D打印塑料线、在3D打印塑料线中心设有吸真空的空芯。空芯为中通。3D打印塑料线为经过定型的3D打印塑料线。
另一目的是提供一种3D打印耗材的应用，具体如下：
(1)对3D打印塑料通过外型模具挤出后；
(2)之后，利用真空棒对3D打印塑料线的中心进行吸真空，即形成空芯；
(3)经过水槽定型成中空芯的3D打印塑料线；
(4)在打印过程，可通过空芯位置对打印效果进行干预。
在一些实施方式中，若需要打印医用产品，在打印刷过程采用人工干预的方式，在打印前先将微量元素通过空芯输送到打印头进行打印。
在一些实施方式中，若在打印过程为避免打印产品变形，需要打印产品进行降温，打印刷过程可采用人工干预的方式，将冷风通入空芯内避免打印产品变形。
本发明的有益效果是：中空芯的3D打印塑料线，采用人工主动干预的方式，可根据不同的需要在空芯加对应的物料，主动调配3D打印耗材的目的，不但保证了打印的效率，而且应用过程也很灵活。另外，通过空芯的物料可以是微量元素，也可以是冷风，因此应用十分广泛。
附图说明
图1为本发明的结构示意图；
图2为本发明的内部结构示意图。
具体实施方式
下面结合附图对发明作进一步详细的说明。
如图1-2所示，一种3D打印耗材，包括3D打印塑料线1、在3D打印塑料线1中心设有吸真空的空芯2。空芯2为中通。3D打印塑料线1为经过定型的3D打印塑料线1。
一种3D打印耗材的应用，具体如下：(1)对3D打印塑料通过外型模具挤出后；(2)之后，利用真空棒对3D打印塑料线1的中心进行吸真空，即形成空芯2；(3)经过水槽定型成中空芯2的3D打印塑料线1；(4)在打印过程，可通过空芯2位置对打印效果进行干预。若需要打印医用产品，在打印刷过程采用人工干预的方式，在打印前先将微量元素通过空芯2输送到打印头进行打印。若在打印过程为避免打印产品变形，需要打印产品进行降温，打印刷过程可采用人工干预的方式，将冷风通入空芯2内避免打印产品变形。
应用时，采用人工主动干预的方式，可根据不同的需要在空芯2加对 应的物料，主动调配3D打印耗材的目的，不但保证了打印的效率，而且应用过程也很灵活。另外，通过空芯2的物料可以是微量元素，也可以是冷风，因此应用十分广泛。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于发明的保护范围。
