Goodyear biologist James Wright compares a precision molded artificial heart (L) with an older handcrafted version. Formed in stainless steel molds (foreground), the newly designed heart is more uniform and reliable than earlier models and can be produced far more rapidly. Using the new technique, ten hearts can be built in a week. Previously, it took two weeks to hand fashion a single heart.
