Russian para-athlete, Dmitry Pavlenko – assisted by 3D printed diving gear – has made a record-breaking dive in Egypt’s Red Sea.

Pavlenko executed the 40-meter independent deep dive on May 7th, 2018 using a buoyancy lever which controlled his air-circulation valves whilst underwater. The lever was designed and created by a student engineering team from Moscow Polytechnic University (MPU) in Russia.

To reach deeper beneath the sea’s surface, divers must wear special vests fitted with two-valves to control air circulation. With his unique anatomy Pavlenko cannot properly control these valves, hence the need for a lever.

Pavlenko - Arms - Legs - Bomb - Blast

Pavlenko lost both his arms and legs in a bomb blast while serving in the Russian army and has made it his goal to surpass fellow quadruple amputee and diver Philippe Croizon’s record-setting dive of 33-meters. Thus, he created a homemade lever. However, this lever eventually became problematic. Calling on Anisoprint, a manufacturer of continuous carbon-fiber FFF 3D printers, and MPU students, Pavlenko inspired the start of project Depth Assault.

The project initiated a hackathon on March 24th to design and create diving equipment that would allow Pavlenko to execute a deep dive crossing 30-meters.

During the day-long event, six student engineering teams produced four different prototypes using Fused Deposition Modeling (FDM) of ABS plastic.

“The competitions that are concluded with the manufacturing of a functional prototype allow [us] to evaluate the training level of the students,” said Pavel Petrov, Head of the Department of Mechanical Engineering at MPU.

Petrov adds, “The students can see the materials processing by pressure and additive technologies and acknowledge that the practical skills are now in demand in society.”

Using ABS alone, the first prototype proved weak when tested against the pressures of deep immersion. Multi-part assemblies also proved to...
