FRESH platform enables 3D printing of collagen (Source: Carnegie Mellon University)
Researchers at Carnegie Mellon University ’s College of Engineering have published a paper detailing a new technique which provides “critical steps” on the path to 3D printing a functional adult-sized human heart.
The new technique, known as Freeform Reversible Embedding of Suspended Hydrogels, or FRESH, enables the 3D printing of collagen to produce tissue scaffolds, mimicking the human body’s cellular make-up, which holds together specialised organ cells via biological scaffolds.
The paper, published in Science journal earlier this month, shows how researchers were able to print pieces of the heart, such as a heart valve or small beating ventricle, from patient-specific MRI data using collagen and living cells. Collagen is a highly desirable but tricky material to print with due to its fluidity. FRESH allows collagen to be printed layer-by-layer, supported by a gel bath, to enable it […]
