New ultrasonic 3D printing tech mends broken hearts and bones without surgery

Sound waves and a special ink to print custom implants and deliver drugs directly to injured tissues

10-Dec-2023

Key points from article :

Researchers developed a method to 3D print inside the body using ultrasound and "sono-ink" that gels when exposed to sound waves.

Could revolutionize medicine by enabling minimally invasive organ repair, targeted drug delivery, and printing customized implants.

Sono-ink repaired bone fractures in chicken legs, patched a damaged goat heart, & delivered chemotherapy drugs in a pork liver.

Reduced need for open surgery, precise targeting of damaged areas, and potentially less side effects.

Sono-ink hasn't been tested in living bodies yet, and potential risks like toxicity and tissue heating need further investigation.

Applications could extend to printing soft 3D materials for electronics, prosthetics, and even personalized footwear.

Further research and development needed before clinical use, but could transform medical treatment and beyond.
