摘要:三维打印技术，也就是我们常说的3D打印技术，如今已经不足为奇了，它是一种新起的科技项目，它的起源最初是从数字的模型建立开始，材料选择易溶解性固体或者小颗粒，分层打印来完成对于物体的建立。所以与其它的技术相比，脑海里想要的任何形状我们都能通过电脑端来完成，而且可以缩短制造产品所需要的时间，在低成本的情况下保证一个高效率的运行，除此之外，不用借助任何的机械加工或者机床打磨甚至模具生产。曲奇3D打印机将会是食品3D打印机中一种新的调试，也是一种新材料的尝试，曲奇3D打印机与巧克力打印机运行方式类似，经过扫描、分层、成型等工序基于3D打印机的工作方式。本篇文章内容主要为曲奇3D打印机的外部结构、机械内部结构、电路电线的安装搭建、软件的识别和转换格式部分，还有曲奇的特性，机械内部的结构部分，了解到了电机的驱动以及控制、机床设计的结构特征，打印头难点的突破，挤出部分的结构设计改善问题，以及一台完整的以曲奇为材料的曲奇3D打印机；外形结构的要求希望能尽可能的做到方便携带、精致，体现出强有力科技感以及新鲜感，能获得大众的喜欢和肯定；电路电线的安装搭建部分需要了解到如何有效的管理对于主板的控制，并且尝试安装到曲奇3D打印机中保证它的独立有效的运行。除此之外就是丢曲奇的特性要研究，关于曲奇种类、融化的温度、成型烘焙温度比以及价格等等的数据收集。所以，要分析市场上热门的3D打印机，比较其机械结构差别并对比优劣，并根据曲奇的自身情况和特性进行改装，保留打印机上的结构优点，再细化到细节，摒弃打印机的不足以及缺点，再制定出一套全新方案，运用设计软件（CAD、UG等）进行虚拟设计来完成上位机的辅助，再通过软件的仿真功能，来验证结构可行性方案。最终，选择零部件的材料和型号的比较和选取，来完成新型曲奇3D打印机的研发。70107

Cookies 3D printer structure and process optimization research and development

Abstract: 3D printing technology, that is, we often say that the 3D printing technology, is now surprising, it is a new technology project, its origin is the beginning of the establishment of the digital model, the material selection of easy to dissolve Solid or small particles, layered print to complete the establishment of the object. So any of the shapes we want in our minds can be done through the computer side, and we can shorten the time required to make the product and ensure a high-efficiency operation at low cost. , Without the use of any mechanical processing or machine grinding or even mold production. The cookie 3D printer will be a new kind of debugging in the food 3D printer, and it is also a new material to try, the cookie 3D printer is similar to the chocolate printer running, after scanning, stratifying, forming and other processes based on the work of the 3D printer the way. The contents of this article mainly for the external structure of the cookie printer, mechanical internal structure, the installation of circuit wires to build, the software identification and conversion format part, there are features of the song, the internal structure of the mechanical part of the motor to understand the drive As well as the structural characteristics of the control, the design of the machine tool, the breakthrough of the print head, the improvement of the structural design of the extruded part, and a complete cookie-making machine with cookies; the structural requirements To facilitate the carrying, refined, reflecting a strong sense of science and technology and freshness, to get the public like and sure; installation of the circuit to build part of the need to understand how to effectively manage the control of the motherboard, and try to install to the cookie 3D printer To ensure that its independent and effective operation. In addition to this is the characteristics of lost cookies to study, on the cookie type, melting temperature, molding baking temperature ratio and the price of data collection. So, to analyze the popular 3D printers on the market, compare the mechanical structure of the difference and compare the pros and cons, and according to their own situation and characteristics of cookies modified to retain the structure of the advantages of the printer, and then refined to the details, to abandon the lack of printer As well as shortcomings, and then develop a new set of programs, the use of design software (CAD, UG, etc.) for virtual design to complete the host computer assistance, and then through the software simulation function to verify the feasibility of the program. Finally, select the parts of the material and model comparison and selection, to complete the new cookie 3D printer research and development.
