The gel coat provides a protective layer, enhancing the wind blades' durability and performance by stabilizing the wood against environmental changes. This approach not only extends the lifespan of wooden wind blades but also ensures consistent performance in variable climates, making it a valuable solution for high-humidity regions.

Alexandros Chronis, RurERG (NTUA), Greece @ 11:00 EEST

In the SmartRUE lab, a commercial 3D printer was modified to increase its z-axis capacity, enabling the production of 60 cm long small wind turbine blades, or blade parts, in a single print. This modification facilitated the use of complex and optimized airfoil designs, surpassing the limitations of hand-carved wooden blades. (con't)
