摘要:

基于响应面方法,探究熔融沉积成型(FDM)技术参数对制备对乙酰氨基酚(APAP)片剂的成型精度的影响规律,得到最优试验方案并进行验证。结果表明,FDM技术制备APAP片剂水平与竖直方向尺寸误差影响因素主次顺序分别为:喷头温度>平台温度>打印速度;喷头温度>打印速度>平台温度。喷头温度与平台温度的交互作用对APAP片剂成型精度的影响极其显著。优化的试验方案为:打印速度为75 mm/s、喷头温度为225 ℃、平台温度为56 ℃,相对误差较小,结果可靠。

Abstract:

Based on a response surface method, the influence of fused deposition modeling (FDM) technical parameters on the forming accuracy of preparing acetaminophen (APAP) tablets was explored, and the optimal experiment plan was obtained and verified. The results indicated that the factors affecting the horizontal and vertical dimensional errors of the APAP tablets prepared by FDM technology showed primary and secondary orders as follows: nozzle temperature > platform temperature > printing speed and nozzle temperature > printing speed > platform temperature, respectively. The interaction between the nozzle and platform temperatures had a significant effect on the forming accuracy of APAP tablets. The relative error of the optimized test plan was small and the result was reliable.
