This 1:1 scale model of an aircraft turbine was created by the R&D department of Grupo Sicnova, which designed it from scratch, based on an analysis of the technique used for real turbines, employed in the aeronautical sector.
The process consists of several phases: design, manufacture using 3D printing, assembly and a final post-processing phase.
Once the 3D design of the whole turbine had been completed and checked, it was divided into fifty pieces, including the blades, with a system to join the different parts together with screws. The parts are made entirely from additive manufacturing, using about 100 kg of black PLA.
A metal chassis has also been designed to support the weight of the turbine (about 110 kg) and to facilitate transportation. Once assembled, the turbine is 2215mm long and has a diameter of 1200mm.
The final post-processing stages of caulking, painting and polishing the piece are completed to ensure a good finish.
