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.

Edits create cells that don’t trigger an immune response, allowing implant recipient to forego immune-suppressing drugs.
Fresh treatments shift the focus from symptom management to repair.
