Printing Time Optimization of Large-Size Powder-Based 3D Printing

Powder-based 3DP was the first technique to print full color 3D objects with continuous tone. However, limited by the size of the printing platform, large 3D objects can hardly be printed efficiently which has affected the spread of this technology. In consideration of the above issues, this paper discussed the relationship between printing time and model height, and a algorithm for optimizing printing time was presented. Ten typical models had been printed to verify the effectiveness of XYX rotation method. The results showed that the maximum time reduction is 65.7% less than the modeling time before optimizing.
