摘要
为了研究陶瓷增强光敏树脂制件的收缩率和硬度,使用面成型光固化技术制作陶瓷增强光敏树脂的制件为研究对象。研究了分层厚度、曝光时间、灭灯时间对制件收缩率和硬度的影响,基于正交试验结合信噪比分析法对工艺参数进行了优化,并得到各参数对优化目标的影响程度。结果表明,分层厚度对Z向尺寸收缩率和硬度的影响最大,曝光时间次之,灭灯时间最小。通过Z向尺寸收缩率和硬度所对应的最优参数的均值得到的最佳工艺参数组合为:分层厚度0.05 mm,曝光时间12.5 s,灭灯时间12.5 s。将此最佳工艺参数组合用于打印鼓型制件,最终测得制件的Z向尺寸收缩率为1.13%,硬度为87 HB。
In order to study the shrinkage and hardness of self-made ceramic-reinforced photosensitive resin parts,the production of ceramic-reinforced photosensitive resin parts using face-moulding photocuring technology was the subject of study.The effects of layer thickness,exposure time,and light-off time on the shrinkage and hardness of the parts were studied.Then,based on the results of the orthogonal experiment,the process parameters were optimized by the signal-to-noise ratio analysis method,and the influence degree of each parameter on the optimization goal was obtained.The results show that the layer thickness has the greatest influence on the Z-direction dimensional shrinkage and hardness,followed by the exposure time,and the light-off time is the smallest.The optimal combination of process parameters obtained by the average value of the optimal parameters corresponding to the Z-direction size shrinkage and hardness is:layer thickness 0.05 mm,exposure time 12.5 s,and light-off time 12.5 s.This optimal process parameter combination is used to print drum-shaped parts,and the final measured Z-direction dimensional shrinkage of the parts is 1.13%,and the hardness is 87 HB.
