[0002] In sand casting production, for customers with personalized needs, in order to reduce the cost of mold making, 3D subtractive processing is used to obtain sand molds and sand cores. The personalized market demand requires the products to be single. 3D subtractive production is more cost-effective than conventional mold manufacturing, and the demand is huge. The conventional method is to use wooden boards, nails and other plates and tools according to the size of the sand block and the requirements of the drawings to make the required three-dimensional model. Under normal circumstances, it is a rectangular model. Self-hardening sand is filled in the model. After curing, the mold is disassembled to obtain the required sand block.
