3D Printing Materials for Underwater Use

Underwater environments, especially saltwater, are tough on materials . Water ingress, hydrostatic pressure, dissolved salts and gases, temperature changes, and biofouling all conspire to degrade parts that perform perfectly in air. When designing and printing parts that will be submerged, choosing the right material is the first and most important decision. Key Material Properties to Consider ...

This study focuses on the current development of 3D printing technology for underwater applications, including the required improvements in the technology itself, as well as new materials .

Additive Manufacturing in Underwater Applications

Additive manufacturing (AM), commonly named 3D printing , is a promising technology for many applications. It is the most viable option for widespread use in automated construction processes, especially for harsh environments such as underwater . Some contemporary applications of this technology have been tested in underwater environments, but there are still a number of problems to be solved ...

Underwater 3D printing could transform maritime construction

An interdisciplinary collaboration has developed a way to 3D-print concrete underwater - a technique that could transform on-site maritime construction and the repair of critical infrastructure.

Best Filament for Long-term Submerged Prints I'm designing a product for underwater use in freshwater ponds. It will be submerged for for months, possibly years, at a time. Assume that PETG is the way to go. My only concern is that PETG is quite flexible. For this use case, however, a more rigid material is preferable. It's not required, as I can add stainless steel supports if necessary. But ...

Underwater Concrete 3D Printing Using Seafloor Sediment

Researchers at Cornell are 3D printing concrete underwater using seafloor sediment, opening new possibilities for maritime construction.

Underwater 3D concrete printing (U3DCP) is an emerging automated construction technology with significant potential for offshore, coastal, and marine infrastructure, enabling in-situ fabrication without dewatering or formwork. Operating in a submerged environment, U3DCP involves tightly coupled interactions between material rheology, hydrodynamics, and robotic process control that ...

Filament choice for under water application

Ive got some parts im working on that will be be used on a boat. Im not sure which filament to use for the parts that will be submerged under water. It will be fresh water only, but id be interested to know wht the requirement would be for salt water as well. Ive read conflicting info about nylon for exterior applications. Does anyone have experience & recommendation for this? Id appreciate ...
