Progress made in 3D bioprinting artificial bones
"The deposition materials can be modified to promote stem cell proliferation"
As with conventional 3D Printing, bioprinting offers the opportunity to create the exact shape of the bone in deposited layers until the bone is fully formed. The concept is that the artificial bone produced using this process can be transplanted into the body, where the structure will form a scaffold that will be replaced by living bone over a period of four-six months.Currently, it takes under two hours to print a small bone structure with trabecular features, indicating that the fabrication could take place within the operating theatre. Subsequently, ensuring that the bone composite material is deposited with the correct viscosity ensures that a smooth surface structure is produced with no stress raising features.
