Protecting Endangered Fairy Terns with 3D Printed Eggs in New Zealand

Across the globe, scientists and conservationists are intensifying their efforts to save endangered species, a challenge made more urgent by accelerating climate change and its impact on traditional habitats. In New Zealand, a critical initiative is underway to protect the native Fairy Tern, known as tara iti in Māori, one of the country’s rarest birds. The Department of Conservation (DOC) has embraced 3D printing technology to create highly realistic replica eggs, offering a vital lifeline for this critically endangered species.

The Fairy Tern population, once widespread, is now confined to just five main nesting sites in north Auckland. These coastal breeding grounds are highly susceptible to environmental threats, particularly high tides and severe storms, which can easily wash away delicate eggs and imperil an entire breeding season. Traditional methods of protection, such as using hand-painted wooden eggs or real eggs filled with wax, often proved inadequate due to their fragility and lack of realism, failing to fool the discerning parent birds or withstand the harsh coastal conditions.

The breakthrough came with 3D printing. Working collaboratively, conservationists leveraged this advanced manufacturing technique to produce eggs that meticulously mimic the real thing. Artist and marine biologist Carina Sim-Smith meticulously painted these 3D printed replicas, ensuring they matched the precise shape, weight, UV resistance, size, color, and texture of natural Fairy Tern eggs. This level of accuracy was paramount, as noted by Natalie Jessup, General Manager of the Endangered Species Foundation: “We were happy to see the replacement eggs were successful at holding nesting sites during risky periods when the real eggs were safely cared for at Auckland Zoo – they were so realistic parent birds had no idea they were not sitting on the real thing.” This innovative approach allowed conservationists to temporarily replace real eggs with their 3D printed counterparts during periods of high risk, giving the genuine eggs a chance to develop in the safety of Auckland Zoo.

The program’s success has been nothing short of remarkable. This past year marked a record-breaking breeding season for the Fairy Terns, with an impressive 22 eggs laid and 14 chicks successfully hatched. This achievement underscores the immense potential of 3D printing as a tool for wildlife conservation, offering durable, precise, and highly customizable solutions for protecting vulnerable species. This innovative application in New Zealand demonstrates how additive manufacturing can play a pivotal role in conservation efforts worldwide, helping to mitigate threats and bolster populations of at-risk animals by providing practical and effective interventions.

EOS Unveils New High-Powered Metal 3D Printing Solution for Copper

EOS, a global leader in high-end additive manufacturing solutions, has once again pushed the boundaries of industrial 3D printing with the launch of its new metal additive manufacturing system, the M 290 1kW. This latest innovation is designed to meet the rigorous demands of advanced industrial applications, particularly those requiring components made from challenging materials like copper.

The M 290 1kW operates using laser powder bed fusion (LPBF) technology, a highly precise method where a high-power laser selectively melts metallic powder layer by layer to build complex geometries. As its name suggests, the printer is equipped with a powerful 1-kilowatt laser. This significantly higher laser power, compared to standard systems, enables faster processing speeds and allows for the creation of denser, more robust parts, which is especially critical when working with materials known for their high thermal conductivity.

What truly sets the M 290 1kW apart is its specialized design for producing high-quality copper parts. Copper has long been a notoriously difficult material to 3D print due to its high reflectivity to common laser wavelengths and excellent thermal conductivity, which can lead to inconsistencies in the melting process. EOS has engineered this machine to overcome these challenges, opening up new possibilities for industries reliant on copper’s unique properties. Currently, two materials are qualified and offered for the system: CuCp, a highly pure copper (99.95%), and EOS Copper CuCrZr, an alloy combining copper with chromium and zirconium for enhanced strength and performance.

This development is particularly relevant for the aerospace and defense sectors, where copper is indispensable. Its exceptional electrical and thermal conductivity makes it ideal for applications such as heat exchangers, electrical connectors, rocket nozzles, and intricate cooling channels in high-performance engines. The ability to 3D print complex copper components with such precision and efficiency allows for innovative designs that are lighter, more thermally efficient, and more integrated than traditionally manufactured parts. This new solution from EOS is set to accelerate innovation in these critical industries, providing engineers with the tools to create next-generation components that were previously impossible to produce.

Sidus Space Achieves Two-Way Communication with its 3D Printed LizzieSat Satellite
