Hydrogen and 3D Printing Technologies: Benefits and Applications

The hydrogen vehicle market is revolutionizing the outlook of the automotive sector.

In this article, we will try to describe the state of the art in 3D printing and hydrogen technology in the automotive field.

2035 will mark the year of the ban on combustion engines; this awareness has sparked a series of million-dollar investments in hydrogen technologies.

The reason for this choice is the need to implement green technologies to save the planet

Hydrogen and 3D Printing Technologies

Will hydrogen technology be the solution?

As of today, that guarantee is not certain; however, it remains a fact that research and investments in this sector are truly substantial.

As of today, the biggest obstacle to launching this sector is the cost of hydrogen production.

Producing this gas, which should simply result from the breakdown of water molecules, is currently too expensive.

The Sector of Hydrogen Cars and the Use of 3D Printing

3D Printing: A Technology Used in Numerous Sectors, Including Hydrogen.

Rapid Prototyping has found application even in this field.

And it is quite simple to demonstrate how the use of 3D printing processes optimizes production and testing costs, even in the development of hydrogen systems.

3D Printing and Engines

3D Printing, compared to conventional production technologies, allows for the rapid production of highly complex geometries.

This accelerates all the steps in the development of new products and optimizes overall costs.

Furthermore, among rapid prototyping technologies, there are new materials and processes that allow the production of final parts for use in the finished product.

Hydrogen cars are not yet ready for mass production.

For this reason, many components are obtained through advanced 3D printing processes, used during the design and prototyping phases.

The 3D printing technology DMLS Direct Metal Laser Sintering certainly plays a crucial role in this field, often replacing milling processes.

The State of the Art in Hydrogen Technology in Italy

Italy is certainly lagging behind other countries in the development and use of this technology.

We are behind both in the development of the technology and in the preparation of infrastructure.

The choice of hydrogen cars is very limited, and if we intend to refuel, we must be aware that there are only two active refueling stations, one in Bolzano and one in Mestre.

However, in the course of 2023, the Ministry of Transport initiated 36 new projects to kickstart the development of the national hydrogen refueling network by 2026.

Despite this, the scenario in our country lags far behind compared to countries like Germany, which already had just over 90 refueling stations in 2023.

Case studies

With all these premises, the world’s largest automotive companies are focused on the development of hydrogen technologies.

And, as well-known, the automotive industry involves not only car manufacturers but also an extraordinarily high number of companies producing components and accessories.

Among the companies committed to this topic, Honda, during the ‘Hydrogen Week 2023,’ presented a new prototype that could be revolutionary.
