Metal 3D Printing Materials: From Titanium to "Metal PLA"

Make It 3D Philippines

The world of 3D printing materials can be confusing. With desktop hobbyist printers becoming popular, the line between real industrial manufacturing and desktop plastic modeling has blurred.

If you want to know what metal materials can be 3D printed, where to source them, and the truth about "metal filaments," this guide will clear up the confusion.

The Truth About "Metal" Filaments

If you have a standard desktop printer, you might have seen spools of metal 3D printing filament online. This leads to a lot of common questions:

  • Is PLA metal actually metal? Does PLA Metal have metal in it? No. PLA (Polylactic Acid) is a biodegradable plastic. "Is PLA just corn?" Essentially, yes — it is derived from fermented plant starch like corn.
  • Is PLA Metal or plastic? It is plastic. So-called "Metal PLA" simply has very fine metallic dust mixed into the plastic to give it a shiny, heavy appearance. It has zero structural strength and cannot be used for mechanical metal parts.
  • Can you drink out of 3D-printed cups? Generally, standard FDM printed plastics are not food-safe due to microscopic gaps where bacteria can grow. However, real, solid stainless steel parts printed via industrial methods can be sterilized and made food-safe!

Real Industrial Metal Printing

To get true, solid metal parts, you need industrial processes like Selective Laser Melting (SLM) or Direct Metal Laser Sintering (DMLS).

So, what type of metal can you 3D print? And what materials are commonly used in direct metal laser sintering?

  • Stainless Steel (316L): The workhorse of the industry. Highly corrosion-resistant and strong.
  • Cobalt-Chrome (CoCr): Extremely wear-resistant and biocompatible, making it the top choice for the dental industry — crowns, bridges, and partial dentures.
  • Titanium: "Can I 3D print titanium?" Yes! Titanium is widely used in aerospace and medical implants due to its incredible strength-to-weight ratio.

On the flip side, what metals cannot be 3D printed? While the technology is expanding, highly volatile, toxic, or extremely low-melting-point metals (like lead or pure mercury) are not practically or safely 3D printed. As for luxury goods — "Can you 3D print gold?" Yes, specialized jewelers do 3D print precious metals, though it requires highly specialized powder management to prevent waste.
