We are proud to share our work on the reconstruction of the missing propellers for the EM-11 “Orka” aircraft – a project that demonstrates how modern technologies can support the preservation and restoration of aviation heritage.
As part of the project, we manufactured a set of propellers using 3D printing technology for the Polish Aviation Museum in Kraków. The greatest challenge was to accurately reproduce the geometry and structural details – so that the components not only looked like the original, but also retained the correct proportions and high precision of manufacture.
What is particularly inspiring is that the EM-11 “Orka” aircraft was, in its day, an innovative design, ahead of the technological solutions of the time. Today, by utilising advanced 3D printing technologies, we can, in a sense, continue this idea – combining modern engineering with the spirit of innovation that accompanied the creation of this machine.
The project was carried out by the team – a brand of New Era Materials specialising in professional 3D printing and modern additive technologies. By combining advanced digital modelling with precise manufacturing processes, it was possible to recreate components with complex structures, which would have been much more difficult and time-consuming to produce using traditional methods.
This project is an excellent example of the synergy between engineering and history:
🔹 additive technologies enable the precise reconstruction of hard-to-reach components
🔹 digital modelling reduces production time and increases accuracy
🔹 modern materials and manufacturing processes open up new possibilities in the field of restoration and reconstruction
We are particularly delighted to have been part of this project and to have contributed to the restoration of aviation history. ✈️
