With the development of the funeral industry, for some bodies missing limbs, 3D model printing is generally used to reconstruct the limbs of the bodies to show respect for the deceased, so 3D model printing equipment is needed.

[0003] For example, a 3D printing device for engineering models with a publication number of CN204123681U includes a processing device.
