基于SLS近似连续梯度密度样件工艺研究

Study on the quasi-continuous gradient density parts based on SLS

为消除内置热源对烧结件密度的影响,制备近似连续梯度密度样件,建立了选择性激光烧结(SLS)相邻烧结层密度补偿的数学模型。通过对功率密度补偿系数的研究,修正离散化样件各个分层的设定功率,制备出了单一材质的近似连续梯度密度下颌骨简化模型样件。实验结果证明了所建立数学模型的可靠性。

To eliminate the effects of the internal heat source on sintered parts and prepare quasi-continuous gradient density parts, a mathematical model of the adjacent sintered layer density compensation based on Selective Laser Sintering （SLS） is es- tablished. The discrete stratified sample of each setting power is corrected by the study of the power density compensation faetor, and then the single material quasi-continuous gradient density parts is produced. The final results show that reliability of the math- ematical model.
