摘要
在3D打印技术中,当前方法是依据该切片方式利用远程送丝和近程送丝相结合的方法,一直存在效率低的问题。为此,提出一种黑陶水土比例、喷头直径、挤出速度等参数对陶坯表面3D打印质量影响试验方法。该方法首先建立适用于陶坯表面的预测模型,给出陶坯表面切削速度、陶坯表面进给量、陶坯轴向切深及陶坯径向切深与陶坯表面的量化关系,建立以表面粗糙度为优化目标的陶坯表面切削参数优化模型,使用最小二乘法理论进行多目标陶坯表面参数优化,分别研究黑陶水土比例以及喷头直径和挤出速度等参数对陶坯表面产生的影响,以陶坯成形时喷头直径垂直于陶坯表面单位移动的距离即可得出陶坯成形试样为依据,完成黑陶水土比例、喷头直径、挤出速度等参数对陶坯表面3D打印质量影响试验。试验证明,在喷头直径为0.6 mm,黑陶水土比例为1∶7,挤出速度为20 mm/s时,能打印出质量良好且具备较高精度的陶坯表面。
In the3D printing technology,the current method is based on the use of the method of remotewire feeding and short wire feeding method,has been the problem of low efficiency.To this end,a blacksoil ratio,nozzle diameter,extrusion speed and other parameters of test methods for ceramic surface3Dprinting quality.The method firstly builds a prediction model for ceramic surface,gives the quantitativerelationship between surface cutting speed,the surface of ceramic ceramic ceramic feeding amount,axialdepth of cut and ceramic ceramic and radial depth of cut surface,based on surface roughness surface ofceramic cutting parameter optimization model for the optimization objectives,using the least squaresmethod of multi-objective optimization parameters of ceramic surface,to study the effect of black soiland the proportion of nozzle diameter and extrusion speed and other parameters on ceramic surface,theceramic forming nozzle diameter perpendicular to the surface of the unit ceramic moving distance can beobtained by ceramic test sample based on the complete test scale and influence of black soil the nozzlediameter,extrusion speed and other parameters on the ceramic surface3D printing quality.Tests show that the nozzle diameter is0.6mm,black soil and water ratio is1∶7,the extrusion speed is20mm/s,canprint out of good quality and have high precision ceramic surface.
