Bioprinting inside the body, without breaking the skin

Ultrasound enables minimally invasive 3D-printing of tissues, therapies, and more.
A new technique for 3D-printing soft materials directly inside the body could allow the creation of complex structures deep within tissue—without making a single incision.
The approach, unveiled this week in Science, uses focused ultrasound to sculpt injected “bio-ink” into tissue-like structures, opening the door to minimally invasive applications in cancer therapy, bioelectronics, and regenerative medicine.
