It should be noted that the inelastic state is an ideal state, and in application, the elastic fabric is difficult to be stretched and unfolded completely to the inelastic state, and only the elastic fabric needs to be stretched and unfolded to the maximum extent, so that the unfolded elastic fabric is similar to the inelastic state, and therefore, the inelastic state in this embodiment refers to the state where the unfolded elastic fabric is similar to the inelastic state.

Specifically, the elastic fabric is placed on a printing platform of a 3D printer, stretched and unfolded to an inelastic state, and fixed by corresponding auxiliary tools after stretching is completed, wherein the elastic fabric can be placed firstly and then stretched, and can also be stretched firstly and then placed and fixed. The fixing can be assisted by tools such as double-sided adhesive tape, clips and the like.

The deformation principle of the environment-adaptive fabric is mainly physical performance, and the elastic fabric is compounded into a 3D structure in an inelastic state, so that the original elasticity of the fabric is recovered at the position of the elastic fabric without the 3D printing structure after the elastic fabric is taken down, the fabric at the position of the 3D printing structure loses part of the elasticity of the fabric, the supporting or bulging effect is realized, and the elastic fabric is changed into the fluctuant and structural deformation fabric from the original plane elastic bread. Therefore, the composite fabric can deform in a preset manner according to the printing structure on the fabric under the influence of external force.
