三维打印机和三维打印方法 Three-dimensional and three-dimensional printers printing method

技术领域 FIELD

[0001] 本发明涉及三维成像领域,尤其涉及一种三维打印机和一种三维打印方法。 [0001] The present invention relates to three-dimensional imaging, and more particularly relates to a three-dimensional and a three-dimensional printer printing method.

背景技术 Background technique

[0002] 3D打印机又称三维打印机,是一种利用快速成型技术的机器,以数字模型文件为基础,采用成型材料,通过逐层打印的方式来构造三维的实体。 [0002] 3D printers, also known as three-dimensional printer, using a rapid prototyping machine, the digital file-based model, using the molding material, layer by layer manner to construct a three-dimensional printing entity. 在打印前,需要利用计算机建模软件建模,再将建成的三维模型“分区”成逐层的截面,即切片,从而指导3D打印机逐层打印。 Before printing, you need to use computer modeling software modeling, and then built a three-dimensional model "Partition" section into a layer by layer, that slice, layer by layer to guide the 3D printer to print. 3D打印机在产品制造业获得了广泛的应用,3D打印机的工作原理和传统打印机基本相同,由控制组件、机械组件、打印头、耗材(即成型材料)和介质等组成,打印原理也基本类似。 3D printer manufacturing products gained wide application, 3D printer works substantially the same as the conventional printer and by the control components, mechanical components, printhead supplies (i.e., molding material) and the medium etc., the printing principle is substantially similar.

[0003] 现有的3D打印机大都采用单打印头,当打印的模型需要彩色成像时,目前通用做法是添加多个打印头,通过多个打印头挤出不同颜色成像材料,继而实现彩色成像。 [0003] Most conventional single 3D printer print head, when printing is required color imaging model, the current common practice to add a plurality of print heads, the image forming materials extruded through a plurality of different color print heads, and then to achieve color imaging. 然而这种具有多个打印头的打印机成本较高,而且多个打印头均设置在一个导杆上,使得该导杆受重力较大,从而导致导杆容易发生变形,进而导致打印物体精度低,误差较大,而且多打印头也不利于运输保护,容易遭受损坏。 However, the higher cost of such printers having multiple print heads, and a plurality of print heads is provided a guide rod, so that the guide rod by gravity larger, causing the guide rods easily deformed, leading to a low precision printing object large errors, but also not conducive to transport multi-head protection, vulnerable to damage.
