A new 3D printing technique that uses ultrasound and “sono-ink” could one day be used to build bones, blood vessels, and other tissues within the body.

Researchers developed a technique to quickly and precisely print biomaterial inside ex-vivo living tissue using a deep-penetrating acoustic volumetric printing (DAVP) method.

Xiao Kuang, PhD, from Harvard Medical School, and colleagues were able to print at centimeter depths through biological tissues, “paving the way toward minimally invasive medicine.”

Reporting in the journal Science, they suggest the technique could be used to correct bone defects or treating non-valvular atrial fibrillation without surgery.

Ultrasound is often used for diagnostic imaging and therapy due to its ability to penetrate a variety of materials deeply. Compared with light,...
