How does 3D metal printing work?

Of all the 3D printing (AM) materials it must be that of 3D metal printing that ‘3D newbies’ consider to be black magic!

Up there with the printing of body parts and guns! It seems to be an astounding sci-fi concept! Surely not an actual technology available for use by any engineer or 3D printing enthusiast?

It hasn’t always been the case. Only in the last seven or eight years has there been an alternative to Direct metal laser sintering (DMLS). With the advent of other AM techniques that could contain metal (or ceramic) particles within a feedstock, rather than a metal powder being the raw material, enabled a more user friendly process.

However safety and a technology that allow an unskilled operator to print successfully is appealing. These are key attributes to a process that use a feedstock (FFF) instead of a metal powder.

How does FDM 3D metal printing work?

A nozzle extrudes heated metal filled filament onto a platform layer by layer until the geometry is completed.

In conclusion, the future of metal 3d printing is very exciting. Undoubtedly there will be new developments and even more exciting developments in the future. For now, there a few options for consumer to choose from.

The development of metal 3d printing has given rise to a number of different technologies from Direct Metal Laser Sinter (DMLS) to Fused Deposition Modeling (FDM) that can print metals. Another process is NeuBeam. It is a very exciting technology that provide the following benefits;,

  • increased flexibility
  • better metallurgy over current processes
  • and complete stability for industrial metal AM applications
