Common Materials Used for Metal 3D Printing

Common Materials Used for Metal 3D Printing

The phenomenon of 3D metal printing began in the 80s, but in recent years, it’s had an explosion of advances that dramatically increased its appeal. Its original uses in niche technology have expanded to include more mainstream customers. The most common materials used for metal 3D printing have many of the same advantages, including faster turnaround, lower pricing, and less impact on the environment. Here’s an overview of the materials we depend on for our custom 3D printing services.


Metal 3D printing has potential in many industries, is well suited for prototyping, and allows for complex designs that can reduce production to a single item. Materials aren’t subtracted during manufacturing. Manufacturers only use what’s necessary, as the 3D printers construct the project in layers. This precision means there’s no step to shape the design, which eliminates nearly all waste that would harm the environment.


Though it was once more commonly used to make small, low-quality prototype parts, 3D metal printing is now bursting with applications. Exciting new technology is being introduced every day, making 3D metal printing possible for larger parts and orders. This results in more lightweight parts, which is a boon for industries such as aircraft construction. There are endless new markets for 3D metal printing, including in industries that manufacture jewelry, car parts, and kitchenware, and the future looks even more surprising. At the consumer level, it provides infinitely more flexibility for complex designs.
