There are many different types of metal out there but there are certain types that are suitable for metal 3D printing. The most common types of metal used for metal 3D printing are stainless steel (316L and 17-4 PH), tool steels (H13, A2, and D2), Titanium (Ti6Al4V), and Inconel 625 as they have high strength and are resistant to corrosion and extreme temperatures. These types of metals can also be easily fused and produce fine quality metal powder, which is an essential ingredient in many metal 3D printing processes.
Some of the benefits that you can reap from metal 3D printing include having the capability to create complex designs, getting work done faster, cutting costs on labor, design, and material, producing parts or structures with excellent physical specifications and being able to customize prototypes according to your needs.
