Additive manufacturing (AM) with metals is currently one of the most promising techniques for 3D-printed structures, as it has tremendous potential to produce complex, lightweight, and functionally-optimized parts. The medical, aerospace, and automotive industries are some of the many expected to reap particular benefits from the ability to produce high-quality models with reduced manufacturing costs and lead times. The main advantages of AM with metals are the flexibility of the process and the wide variety of metal materials that are available. Various materials, including steel, titanium, aluminum alloys, and nickel-based alloys, can be employed to produce end products.

The objective of this special issue is to collect recent research works focusing on AM with metals. This issue includes 5 papers covering the following topics:

- Powder bed fusion (PBF)

- Directed energy deposition (DED)

- Wire and arc-based AM (WAAM)

- Binder jetting (BJT)

- Fused deposition modeling (FDM)

This issue is expected to help readers understand recent developments in AM, leading to further research.

We deeply appreciate the contributions of all authors and thank the reviewers for their incisive efforts.
