Zusammenfassung: | Disclosed are a 4D printing method using thermal anisotropy and thermal transformation, and the resulting product. The method includes (a) artificially planning transverse printing paths and longitudinal printing paths on a specimen to impose a thermal anisotropy to the specimen, (b) sequentially and alternately forming transversely printed layers and longitudinally printed layers on the specimen by printing a thermoplastic polymer in transverse and longitudinal directions to build a 3D printed product, (c) heating the 3D printed product so that the 3D printed product thermally transforms in a specific direction, and (d) controlling heating time to obtain a 4D printed product having a desired final shape which is formed through the transformation of the 3D printed product over the heating time. |
