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

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,采用打印效率和打印速度对偶分析方法,融入频分多路复用方法实现桌面型3D打印机的多目标集优化控制,并对速度量化指标进行评估,根据不同频率传送各路打印请求信息,实现打印速度提升。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。

Based on the analysis of traditional 3D structure and working principle of the printer,we selected ARM Cortex-M3 kernel LPC1768 as micro controller and adopted the fused deposition modeling（ FDM）. According to the traditional using of single fixed data transmission,the printing speed was too slow,we adopted the printing transfer and printing speed dual efficiency analysis method,integrated into the frequency division multiplexed method to implementation desktop of 3D printer set of multi-objective optimal control,and to evaluate speed quantitative assessment.According to the enquiring different frequencies of the printing system,the frequency division multiplexing method can be applied to transfer the printing request messages to all strips of the 3D printer system. Finally,we tested the performance of the designed 3D printer through simulation and built a test platform to verify the feasibility and effectiveness of the desktop 3D printer control system design.
