摘要
基于FDM技术的3D打印机喷头系统热分析的思路,利用ANSYS Workbench有限元分析法,针对2种不同材料、2种不同喉管截面积和5种环槽宽度共9种比较方案,进行喷头系统热分析。结果表明:喷嘴出口处变形最大,接触部分的温度最高,上下端的极限位置温度最低;不锈钢材质更有利于喉管温度分布;有喉管环槽的喷嘴可以减少喷头热量损失;合理径宽比更有利于喉管的散热。
With the mindset of the thermal analysis on 3D printer nozzle system based on FDM technology,and by means of ANSYS Workbench finite element analysis method,a thermal analysis of the nozzle system was conducted for a total of 9 comparison schemes,including two different materials,two different throat cross-sectional areas,and five ring groove widths.The results show that the maximum deformation occurs at the nozzle outlet,with the highest temperature at the contact area and the lowest temperature at the upper and lower limit positions,stainless steel material is more conducive to the temperature distribution of the throat,nozzles with throat grooves can reduce the heat loss of the nozzle,a reasonable aspect ratio is more conducive to the heat dissipation of the throat.
