Dmitry Pavlenko is a para-athlete diver who set a world record in unassisted diving in open water.
One of the tasks of Dmitry’s team was to design and fabricate a buoyancy compensation system. Specifically a lever to control air inflation and release in order to maintain buoyancy and manoeuvrability.
In the original design of the system, a steel spoon was used as a lever, but it was not particularly convenient and it broke during the 14th dive.
As part of the programme intended to support the para-athlete, the students of Moscow Polytech University designed several modifications of the component considering the athlete’s anatomy. In the end, three ABS prototypes were printed on a 3D-printer. However, they did not prove to be durable enough: while it is lifted on board, the components would touch the shipboard and break down.
The solution was found in a component made of carbon-fibre-reinforced PETG on Composer A4 additive machine.
A composite lever helped Dmitry Pavlenko make a 40m deep unassisted dive in an open sea and set a world record. This accomplishment was recorded in the Russian Book of Records. Dmitry and his team are planning to use the component for future dives and… new records.
