Researchers have developed ceramic inks for a 3D printer, which allow you to print the cooler material at room temperature using living cells.

3D printing internal organs, skin and blood vessels is a challenge, since all these tissues consist of living cells. However, the bone is a mixture of alive and inorganic compounds in a structured mineral matrix. Therefore, printing artificial bones opens up a lot of applications in medicine: from the restoration of damaged areas before the treatment of cancer and other diseases.

Currently, the most progressive method of recovery is the creation of an autologous transplant obtained using a bone fence from another part of the patient’s body. Unfortunately, this method is associated with high risk of infection and is not suitable if a large amount of material is required.

Therefore, a team of bio-engineers from the University of New South Wales has developed biocompatible inks for a 3D printer, which can be printed in an aqueous medium, such as body. When placed in the gelatin bath or another solution, the phosphate material forms a paste, which at room temperature solidifies in a porous nanocrystalline matrix, with a structure of similar bone tissue.

Created inks are suitable for standard 3D printers with a special nozzle in the form of an needle with a diameter of 0.2-0.8 mm. In addition to the ceramic composition, they also contain living cells that interact with the artificial structure and are divided within a few weeks after printing with 95% vitality.

In the course of the study, scientists have successfully created synthetic bone structures in size up to 5 mm. Next, the team will print larger samples and will begin testing autologous grafts on small laboratory animals. Ultimately, the technology will print bones directly in the patient’s body.

Recall that earlier scientists also invented biocherry and robotic tools for three-dimensional
