More and more people are starting to incorporate 3D printed plastic components into various applications across different industries. However, it's not always the best choice. After all, 3D printed parts are made in layers, which can make them less durable compared to injection molded parts. This makes many people hesitate before using them in critical situations. Imagine putting a 3D printed part under extreme pressure—what would happen? That’s exactly what researchers and 3D printing enthusiast Martin Baumers wanted to find out.
Baumers and his team launched a project called Deep-Z, a practical, non-academic research initiative aimed at exploring whether 3D printing could be used to create cost-effective equipment for deepwater exploration. In May 2015, they tested their idea by sending a 3D printed submarine, controlled by Lego divers, into the depths of Lake Iseo in northern Italy. The lake is known for its depth and challenging underwater conditions.
The test was a success. The 3D printed device reached a depth of 200 meters without any issues, and it remained intact despite the immense water pressure. This proved that 3D printed parts can be reliable for deep-water applications.
The project began with a waterproof case for a GoPro camera, which was used to capture footage of the 3D printed toy submarine. Baumers attached the submarine to a metal line and added a pressure-resistant LED light on top for better visibility. He didn’t use any desiccant inside the camera, as the GoPro already had a waterproof casing. He also secured the Lego diver with epoxy to keep him safely inside the submarine.
The small 3D printed submarine and the camera housing were made from nylon using SLS (selective laser sintering) 3D printing technology. “This is a strong material that can withstand demanding environments,†Baumers explained. All the STL files for these parts are available for free on the project’s website, encouraging others to experiment and build upon their work.
While the results were promising, Baumers acknowledges that more testing is needed. For example, how would the same components perform in saltwater? Still, this project has opened up new possibilities for 3D printing in underwater applications. It's possible that 3D printed underwater drones may soon become a reality.
