Innovation for coastal resilience students creating living sea walls with 3D Printers

Coastal erosion is a critical issue that threatens our shorelines and the communities that depend on them. As the devastating impacts of climate change become increasingly evident, innovative solutions are essential to protect our coastal areas. In a remarkable blend of technology and environmental stewardship, Jersey College for Girls and Les Quennevais have embarked on a joint effort to develop and design tiles that can be affixed to the sea wall at Elizabeth Marina. Students are harnessing the power of 3D printers to create living sea walls.

The students begin by collecting data on local marine ecosystems and the specific needs of different species. Armed with this knowledge, they design complex 3D models using specialized software. These models are then translated into physical structures using 3D printers. The resulting living sea walls are made from biodegradable materials that promote the growth of coral and other marine organisms.

Carbon Sequestration and Oxygen Production Coral reefs are known for their ability to sequester carbon dioxide, helping mitigate climate change impacts. Students indirectly support carbon sequestration efforts by fostering the growth of coral reefs within the living sea walls. Additionally, the increased presence of marine plants and organisms leads to more excellent oxygen production, benefiting the marine environment and nearby communities. These living sea walls can be deployed in vulnerable coastal areas worldwide by involving multiple stakeholders. Ports of Jersey aims to integrate environmentally friendly practices into their operations, ensuring the long-term health and resilience of coastal ecosystems.

Audi 3D prints Grand Prix Racer

Audi has used 3D printing to produce a scaled model of a historical Grand Prix racer Auto Union Type C, from 1936.  Audi 3D printed different pieces of the model and assembled the car.  Audi used a 3d printer that uses aluminum or steel powder.  The 3D printer uses a laser to melt the metal powder.  Layers and layers of the metal powder are melted to form parts of the car.  This process allows the creation of parts having complex geometries that are very difficult to produce using conventional manufacturing techniques.  With the technology, the 3D printer can produce objects up to 24 cm long and 20 cm high.

Audi is looking forward to using this technology for mass production.  According to Dr. Hubert Waltl, head of toolmaking for the Volkswagen group shown in the picture below driving the replica car, “We are constantly exploring the boundaries of new processes.  One of our goals is to apply metal printers in series production.”
