1.Simply speaking, 4D printing adds a time dimension to 3D printing, so that objects can change shape with time.
3D printing is a kind of rapid prototyping technology, which is based on digital model files, uses powdered metal or plastic and other bondable materials to construct objects through layer-by-layer printing, which can quickly and efficiently manufacture digital three-dimensional models into The entity greatly improves the efficiency of designing and manufacturing objects.
In 3D printing, objects are constructed layer by layer, maintaining rigidity in structure and shape. 3D printing has penetrated into industry and households in many ways. For example, using 3D printing technology to build houses, improve engineering efficiency, and free workers from dangerous construction environments; print human ears to treat microtia (3D printing and injectable gel use living cells to shape almost the same as human ears In the aerospace field, NASA even sent a 3D printer to the International Space Station.
2.4D printing brings 3D printing to a whole new level of technology.
4D printing, to be precise, is a material that can deform automatically. It only needs specific conditions (such as temperature, humidity, etc.) and does not need to connect any complicated electromechanical equipment. It can automatically fold into the corresponding shape according to the product design. The key to 4D printing is "smart materials". These materials can be deformed into new structures under the influence of external stimuli such as water or heat, that is, they can transform from one shape to another.
