为了开发碳水化合物类的新快速成型材料, 对蔗糖的物化材料性质和影响选择性激光烧结的成型因素进行了分析。利用SLS-300成型机进行实验, 并制作出蔗糖模型。得到一些初步的工艺参量以及能量密度对成型质量(强度、颜色、表面粗糙度)的影响规律。结果表明, 蔗糖是可以作为选择性激光烧结材料的, 这为后续研制专用蔗糖3-D打印机提供了实验依据。

In order to develop the carbohydrate as new rapid prototyping material, the physical and chemical properties of sucrose and the effective factors of forming quality of selective laser sintering (SLS) were analyzed. After the experiment, the sucrose models were made by SLS-300 prototyping machine. Some preliminary process parameters were acquired. The effective laws of energy density on forming quality (intensity, color and surface roughness) were gotten. The results confirm that sucrose is available as SLS material. The research provides the experimental basis for the subsequent development of dedicated sucrose 3-D printer.
