Medical science is advancing toward biofabrication — growing organs, tissues, and limbs in labs using 3D printing and stem cells. In the near future, people may order custom organs “off the shelf” to replace failing parts or upgrade their bodies.

This technology promises to eliminate transplant shortages and revolutionize healthcare. But it also raises ethical questions: Will such procedures be affordable and accessible, or deepen health inequalities? Could “designer” organs lead to new forms of human enhancement and social stratification?

Biofabrication could redefine what it means to be human — a world where bodies become modular, customizable, and interchangeable.
