The article "3D-Printed Liver Models Help Surgeons "Rehearse" Cancer Surgeries" from BBC Science Focus explains how scientists have developed a method to 3D print realistic models of cancer patients' organs. These models include imitation tumors and blood, allowing surgeons to practice procedures before performing them on real patients.

The article "3D-Printed Terracotta Reefs Offer New Hope for Saving Coral Ecosystems" from BBC Science Focus reveals that Israeli researchers are creating detailed artificial coral reefs using 3D printing. These terracotta reefs mimic real coral shapes and offer homes for marine organisms, helping coral reefs recover. The goal is to use this technology in oceans around the world to support marine biodiversity.
