Abstract
In order to develop new material applied in food, medicine and biological engineering based on selective laser sintering rapid prototyping, the sucrose was used to carry out thermal gravity and differential-thermal analysis by thermal gravity/differential calorimetry. Sucrose powder and starch-sucrose mixed powder was sintered by using SLS300 rapid prototyping machine and after experimental analysis, the sinter quality was assessed. The results show that when the heating temperature is between 187℃ and 220℃,sucrose can guarantee good forming quality. The modified sugar mixture material by starch can accumulate forming and its surface quality is better than that of single sugar powder sintering molding. The dimension error is 2.1% and the maximum bending strength is 0.5620MPa. It meets the requirements of the general strength of food. The study has important significance for 3-D printing technology application in the field of food.
