4D printing adopting 3D printing’s multi-material approach.
According to Qi Ge, and scientist from mechanics, mechatronic systems,” a simple and versatile multi-material 3-D printing approach to fabricate highly complex, hybrid 3-D architectures. They then used a self-built digital-light processing multi-material 3-D printer to form hydrogel-polymer hybrid 3-D structures. The team displayed a series of applications including a 3-D printed meniscus, 4-D printed cardiovascular stent and a 3-D printed ionic conductor, as advantages of the approach.”
