3D printing method for easy-to-deform product

The invention relates to a 3D printing method for an easy-to-deform product. The 3D printing method for the easy-to-deform product comprises the following steps that S1, the shape, the weight and the size of a to-be-printed product are measured and calculated in three-dimensional software; s2, the structure of the supporting piece is determined according to the shape; s3, the number of the supporting pieces is determined according to the weight and the size; s4, generating a three-dimensional combined model of the support piece and the to-be-printed product in the three-dimensional software; s5, slicing the three-dimensional combined model to obtain a plurality of slice layer data; s6, inputting the data of each slice layer into 3D printing equipment; and S7, the 3D printing equipment prints the to-be-printed product layer by layer according to the data of each slice layer. According to the 3D printing method for the easy-to-deform product, the non-contact type supporting piece is adopted for supporting the p
