3D printing technology application in the block casting

The block was produced by casting technique because it’s complex shape. The traditional casting process is sand casting, but the casting blank is often defective at its bottom, because the local of the casting blank in design of gating system.Now the limitations of the gating system are solved through the introduction and application of 3D printing technology,and simulate the pouring process and the defect part by software,improve the yield of castings.
