How Does Metal 3D Printing Work? (Technologies & Techniques)

Make It 3D Philippines

Additive manufacturing sounds like science fiction, leading many people to ask the fundamental question: Can a metal part be 3D printed? Yes, absolutely. Can 3D printing be done with metal? Not only can it be done, but it is currently revolutionizing the aerospace, medical, dental, and automotive industries. If you are curious about what metal 3D printing is and how it actually creates solid steel from a digital file, let's dive into the technology.

The History: When did 3D metal printing come out?

To understand the tech, it helps to know its origins. The earliest forms of metal additive manufacturing began in the 1990s. The process of Direct Metal Laser Sintering (DMLS) was pioneered by a German company in 1995, proving that lasers could successfully fuse metal powder into solid objects. Since then, the technology has evolved from massive, room-sized industrial machines to highly efficient, accessible desktop units.

What is 3D metal printing technology called?

If you are researching the industry, you will encounter a lot of acronyms. There are several distinct metal 3D printing types and techniques:

  • SLM (Selective Laser Melting) & DMLS (Direct Metal Laser Sintering): The most common and robust metal 3D printing technology. A high-powered laser traces a cross-section of a 3D model onto a bed of fine metal powder, melting the particles together. The bed lowers, a new layer of powder is spread, and the process repeats.
  • Binder Jetting: An inkjet-style printhead deposits a liquid binding agent onto metal powder. The resulting "green" part must then be baked in a furnace to sinter the metal together.
  • Metal Jet 3D Printing: Similar to binder jetting, this uses HP's proprietary technology to rapidly deposit binding agents, aimed at high-volume production.

How Metal 3D Printing Works in the Modern Era

Because parts are built layer by layer, engineers can design complex internal cooling channels, weight-saving lattice structures, and consolidated assemblies that are physically impossible to create with a traditional drill or CNC mill.

At Make It 3D, we specialize in SLM technology, which provides fully dense, end-use metal parts.
