Projects – Hybrid – OPTIMAM

The OPTIMAM project will focus on the reuse of electrolytes that have reached the end of their useful life. Instead of discarding these electrolytes, their revaluation will be sought by creating a new material with advanced acoustic properties. This material will be used to manufacture metaporous surfaces (MpS) with the potential to significantly improve acoustic properties in various applications.

The researchers behind OPTIMAM will explore the possibilities of 3D printing technology to produce these new metamaterials with complex geometries and excellent sound absorption capabilities.

The project will focus on the reuse of recycled solid electrolytes and 3D printing technologies, such as Direct Ink Writing (DIW) and hybrid 3D printing (DIW + FDM). The use of these technologies in medium-sized additive manufacturing equipment will allow the optimization of acoustic materials with 3D printed MpS geometries.

In addition to technical innovations, OPTIMAM has a strong commitment to sustainability and reducing environmental impact. By reusing solid electrolytes and taking advantage of 3D printing technologies, the project will significantly contribute to the reduction of equivalent CO2 emissions produced during the incineration process, in line with current legislation, such as Law 16/2017 on climate change.

The creation of new high-performance acoustic materials from secondary raw materials at the end of their useful life, together with the optimization of complex geometries, will reduce the demand for virgin materials and conserve natural resources. This represents an important step towards sustainability and reducing the environmental impact on the acoustics industry.

Finally, the new materials developed within the framework of the OPTIMAM project will be tested in a prototype of tunnel ventilation silencer, thus demonstrating its ability to significantly improve noise reduction in real-world applications. With this initiative, OPTIMAM is emerging as a revolutionary project that promises a quieter and more sustainable future for all.
