Provided are a 3D printing model slice manufacturing apparatus, a 3D printing device and method, and a 3D printing model. The 3D printing model slice manufacturing apparatus comprises: a driving means (10) comprising a plurality of driving units (11), the driving units (11) being configured to form an electric field, the driving means (10) being configured to drive a liquid 3D printing material located on a surface thereof to flow under the control of the electric field so as to form a pattern to be printed; and a curing assembly (20) provided opposite to the driving means (10) and configured to provide light that cures said pattern into a slice. This 3D printing model slice manufacturing apparatus can help to improve accuracy of 3D printing.
