Scientists from Duke University and Harvard Medical School (USA) have presented a new 3D printing method aimed at creating objects directly within the human body. They have developed a biocompatible injection that responds to ultrasonic waves.
Development, defined as a “deep -proof acoustic volumetric printing” (DVAP) is based on photosensitive ink, which is approved under the influence of light. However, since light does not penetrate the skin, scientists had to use ultrasonic waves. This process that uses the so-thermal effect can be used in the future to restore bones or adjust the heart valves without the need for complex surgery.
The study has already been tested in a series of tests, where biocompatible ink was successfully used to create complex structures in the heart of a goat and solve the problem of bone defect in chicken paws. Although the development is early, scientists see the potential for further research and the possible use of this technology in medicine.
