Abstract：
Manufactured sand molds with complex patternless casting.Set up two group of contrast experiments which are positioned directly by 3D printing checking gauge and indirect position structure to compare sand mold assemble positioning precision.By scanning and analysis the deviation of the sand core and mold after assemble,the results shows that the deviation by 3D printing checking gauge is the smallest among the two methods,thus is the better way to control positioning precision of sand mold.
