Colossal Biosciences has successfully hatched 26 live chicks [1] from 3D-printed artificial eggs that require no supplemental oxygen [2].
This development represents a significant milestone in de-extinction technology. The ability to sustain avian embryos in a synthetic environment could eventually allow scientists to rescue endangered species or attempt to resurrect extinct birds, such as the New Zealand moa [3, 4].
The company announced the breakthrough on May 19, 2026 [5]. The firm said the artificial eggs were designed to mimic the biological functions of a natural shell, providing the necessary environment for the chicks to develop and hatch without external oxygen support [2].
Despite the success, some experts have questioned the terminology used to describe the breakthrough. While the company describes the shells as artificial, some reports indicate the technology lacks certain components to be considered a fully artificial egg [1].
There is also a divide regarding the immediate application of the research. Colossal Biosciences views this as a direct step toward bringing back the giant moa [4]. However, independent scientists said the claim that this technology can potentially bring back extinct birds remains unproven [1].
The project focuses on the intersection of additive manufacturing and synthetic biology. By utilizing 3D printing, the researchers aimed to create a porous structure capable of gas exchange—a critical requirement for embryonic survival—without relying on mechanical ventilation [2].

This achievement demonstrates that synthetic shells can support complex avian life, moving the concept of de-extinction from theoretical modeling to physical application. While the ability to hatch chicks is a technical victory, the transition from hatching common birds to resurrecting extinct species requires overcoming significant genetic and biological hurdles that current 3D-printing technology alone cannot solve.
