一种笛卡尔坐标下的多功能3D打印系统设计

Design of A Multifunctional 3D Printing System in Cartesian Coordinate

3D打印系统能快速打印战场所需的一些零部件和特殊伪装防护器材,针对战场上保护自身、欺骗敌方的需求,设计了一款多功能3D打印系统。该系统以ATmega 2560作为核心处理器,采用A4988驱动步进电机和挤出机,应用模糊比例-积分-微分(PID)控制算法,更加稳定精确地控制温度。利用该打印机系统对某电磁定位系统0.38~2 GHz频段进行建模及打印,与传统工艺相比,缩短了生产周期,节省了原材料,仿真质量约为传统工艺铸件质量的一半,为军用伪装、外场快速修补提出一种新思路。

The 3D printing system can quickly print some parts and special camouflage protective e-quipments needed on the battlefield.For the needs of self-protection and deceiving enemy on the battlefield,a multifunctional 3D printing system has been designed.The system uses ATmega 2560 as the core processor,uses A4988 to drive stepper motors and extruders,and applies fuzzy propor-tional-integral-differential(PID)control algorithm to control the temperature more stably and ac-curately.The printer system is used to model and print the electromagnetic positioning system with the frequency band of 0.38~2 GHz.Compared with traditional technology,it shortens the production cycle and saves raw materials.The simulation mass is about half of the mass of tradi-tional castings,which proposes a new idea for military camouflage and quick patching in the out-field.
