Description
本实用新型涉及打印设备，具体涉及3D打印喷头及3D打印设备。The utility model relates to a printing device, in particular to a 3D printing nozzle and a 3D printing device.
3D打印(3D printing)，即快速成型技术的一种科技产品。它是一种以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。3D printing, a technology product of rapid prototyping technology. It is a technique for constructing an object by layer-by-layer printing based on a digital model file using a bondable material such as powdered metal or plastic.
3D打印头通过向3D打印平台上挤出打印原料，继而形成三维实体，打印头主要是利用成像打印原料的连续挤压，将熔融状的打印原料通过喷嘴的喷口挤出，然后熔融状打印原料层层堆积实现三维物体成型。由于采用分层累积方法成型，例如将PVC线性材料通过步进电机带动齿轮转动，通过齿轮压力将PVC材料送入喷头，利用PVC材料的热溶化，冷凝固原理，加热溶化为流体后喷出，逐层遇冷最后形成各种所需形状的立体物；打印金属则是以高功能激光或电子束为热源，逐层溶化金属粉末，最后形成所需要的金属立体物；打印石膏则是喷出胶水，逐层粘接来实现石膏物体；而打印巧克力则是采用注射式喷头方式，将巧克力逐层喷出打印等待。因此打印成型时间一般都很长，并且打印层的层与层之间连接仅仅是通过熔融状的打印原料黏结后冷却，这样一来，未完全冷却的打印原料会因自重而变形，特别本身是软质的打印原料更甚，同时放置一段时间后，还会导致层与层之间分开。The 3D print head forms a three-dimensional entity by extruding the printing material onto the 3D printing platform, and the print head mainly uses the continuous extrusion of the image printing material to extrude the molten printing material through the nozzle of the nozzle, and then melts the printing material. Layer stacking enables three-dimensional object formation. Due to the stratified accumulation method, for example, the PVC linear material is driven by the stepping motor to drive the gear, and the PVC material is sent to the nozzle through the gear pressure, and the molten material is melted into a fluid and then ejected by the hot melting principle of the PVC material. The layer-by-layer cold is finally formed into three-dimensional objects of various desired shapes; the printing metal is a high-function laser or electron beam as a heat source, and the metal powder is melted layer by layer to form a desired three-dimensional metal; the printed plaster is ejected. Glue, layer by layer to achieve gypsum objects; while printing chocolate is by injection nozzle method, the chocolate is sprayed out layer by layer to print waiting. Therefore, the printing time is generally long, and the layer-to-layer connection of the printing layer is only cooled by the bonding of the molten printing material, so that the printing material which is not completely cooled is deformed by its own weight, in particular, it is itself Softer prints are even more versatile, and when placed for a while, they also cause separation between layers.
例如，在一些情况下，打印原料例如环氧树脂类的打印原料需要加上固化剂，或其它添加物，特别是软质打印原料。如果批量混合，混合的打印原料来不及及时用完，则剩余的打印原料会固化，而批量混合少则又不够用。
For example, in some cases, printing materials such as epoxy-based printing materials require the addition of a curing agent, or other additives, particularly soft printing materials. If the batch is mixed and the mixed printing materials are not used up in time, the remaining printing materials will solidify, and the batch mixing is not enough.
为此，期望寻求一种技术方案，以至少减轻上述问题。To this end, it is desirable to seek a technical solution to at least alleviate the above problems.
