基于ARM的桌面型3D打印机控制系统的设计与优化

在分析传统3D打印机结构组成和工作原理的基础上，选用ARM Cortex-M3内核 LPC1768为微控制器，采用熔融沉积造型技术（FDM），针对传统采用单路固定数据传输导致打印速度过慢的问题，给出基于频分多路复用的速度提升法，采用对偶分析法对打印效率与速度进行量化评估，根据频率的不同对各路打印请求信息进行多路传送。通过仿真并搭建测试平台，最后，对设计的3D打印机进行性能测试，验证该桌面型3D打印机控制系统设计的可行性与有效性。

Design and Implementation of Control System for FDM 3D Printer Based on ARM

On the basis of analyzing the structure and working principle of the traditional 3D printer, the operation principle of the selected arm Cortex-M3 kernel LPC1768 microcontroller, using fused deposition modeling (FDM), according to the traditional 3D printer using one-way fixed data transmission lead print speed too slow, and the speed of frequency division multiplexing (OFDM) based on lifting method, and quantitative evaluation of the efficiency and the speed of printing using dual analysis method. According to the frequency of the different for various print request information multiplex. Finally, through the simulation and build a test platform, the design of the 3D printer performance testing and verifying the desktop 3D printer control system design of the feasibility and effectiveness.
