The research team believes that the designed scaffold can have multiple applications with biomimetic structures, such as bones/ligaments, nervous tissue, and skeletal muscle, and is currently conducting research accordingly. This may be the beginning of the many applications of body regeneration but have much potential. The microchannels have both increased bone tissue formation and induced growth of blood vessels near the graft site in a mouse model.
Hydroxyapatite, the main mineral of which dental enamel and dentin are composed, is a widely used ingredient for dental implants, artificial bones, and cosmetics. Recently, a Korean research team announced amazing results in regenerating animal muscles and bones using 4D printing technology. Researchers designed a microchannel scaffold made of a collagen and hydroxyapatite combination.
Technically, people could stop buying clothes altogether and print clothes every day since 3D printers print on fabric just like ink does on paper. 3D bio-printed hearts and 3D printing prosthetic limbs have now become possible. Due to its more advanced nature than conventional 3D printing technology, 4-dimensional printing is expected to revolutionize life sciences, nanoscience, and aerospace industries, taking theoretical ideas from Science Fiction into surreal real-life realizations.ģD printing refers to the revolutionary implementation of three-dimensional processing by stacking materials one by one. What was once considered only science fiction is becoming a reality right in front of our eyes.Ī recent breakthrough in 4D printing technology in bioengineering enables shaping human bone structures. 4D printing can also change nerve tissues, skeletal muscles, and ligaments attached to skeletons - allowing people to ‘print’ shape-shifting 4D life materials. Those who familiar with the Japanese animation 'Galaxy Express 999' might remember that the main character Tetsuro wanted a machine body, giving him the ability to live forever.
