PRINT is an ARPA-H program focused on developing ways to biofabricate replacement organs using regenerative medicine and bioprinting. Its stated goal is to produce personalized, immune-matched organs using a patient’s cells or cells from a biobank. The program’s technical areas address generating organ cell types, manufacturing those cells at scale, and biofabricating and testing organs. Its initial focus includes kidneys, hearts, and livers. The work also encompasses cell manufacturing, biomaterials, modeling, and tissue engineering.
