Can You 3D Print with Metal?

Here’s What You Should Know

If you’re new to the world of 3D printing, you might think it’s only for making plastic toys or fun desk gadgets. But here’s a surprising fact: Yes, you can 3D print with metal!

It’s not science fiction—it’s science fact. Engineers are using metal 3D printing to build everything from jet engine parts to dental implants. But how does it work, and can everyday people try it? Let’s break it down in plain English.

How Metal 3D Printing Works

Just like with plastic 3D printing, the basic idea is the same: build an object layer by layer. But instead of using melted plastic (like PLA), metal printing uses fine metal powder and super-hot lasers or electron beams.

The two most common types of metal printing are:

🔥 1. Selective Laser Melting (SLM) or Direct Metal Laser Sintering (DMLS)

These printers use a powerful laser to melt and fuse metal powder into solid layers. Each new layer is spread over the top and fused again until the object is complete.

⚡ 2. Electron Beam Melting (EBM)

Similar to laser-based printing, but instead of a laser, Electron Beam Melting uses an electron beam in a vacuum. It’s mainly used for high-end aerospace and medical parts.

What Metals Can Be 3D Printed?

A variety of metals can be used for 3D printing, including:

• Titanium – lightweight and super strong
• Stainless Steel – durable and corrosion-resistant
• Aluminum – lightweight and great for prototypes
• Cobalt Chrome – used for dental and medical implants
• Copper, Bronze, Inconel, and even precious metals like gold and silver in specialized machines

Can Regular People Print with Metal?

Here’s the catch: metal 3D printing is not cheap or beginner-friendly.

Metal printers can cost tens or even hundreds of thousands of dollars, and they often require special environments (like inert gas chambers) and post-processing (grinding, polishing, heat treatment).

So, while it’s possible, it’s usually reserved for:

• Aerospace companies
• Automotive manufacturers
• High-end medical or dental labs
• Industrial designers or researchers

That said, there are more affordable options that mimic metal finishes…

What About Metal-Look Prints?

If you want to make things that look like metal (but are printed on a normal 3D printer), you can use metal-infused PLA. These are filaments mixed with fine metal powder—like copper or bronze—so the prints have a metallic feel and shine.

They don’t have the same strength as real metal, but they’re great for art, jewelry, or display pieces.

Is Metal Printing the Future?

It's absolutely plausible. As the technology becomes more accessible, we’ll see more metal printing in custom manufacturing, medical devices, and even home repair parts. But for now, it’s mostly a tool for professionals.

What’s Next?

Until then, you might be wondering:

What else can I realistically print at home with a regular 3D printer?

Great question. There are plenty of practical 3D prints for home—useful, fun, and surprising things you can make right on your desktop.

From cable organizers to kitchen gadgets to personalized gifts, you’ll be amazed at how many helpful things you can create yourself.
