Additive Manufacturing

What is Additive Manufacturing?

Additive manufacturing (AM), sometimes referred to as 3D printing, is a manufacturing process used to produce three-dimensional solid parts and components. Objects are created using a series of additive layers put down in succession, each slightly different than the one before it, to create a finished 3-D part. Since material is added to create the part, this process is known as additive manufacturing. This process is completely the opposite of traditional part production in which a part is made by removing material through a machinig process. This method of manufacturing can be referred to as “subtractive” because material is removed from the part.

There are numerous advantages to the AM process, including:

  • Processing of complex parts to near net shape
  • Minimizes need for expensive tooling
  • Reduces design risk / less expensive to prototype
  • Compressed time from prototype to production
  • Potential to create distinctive alloys / microstructures
  • Smaller environmental footprint - less energy, waste
  • Production is easily adapted to change in parts
  • Lighter weight alternative to solid parts

GTP is currently developing tungsten, molybdenum and tungsten carbide-cobalt (WC-Co) based powders ideally suited for achieving high density parts fabricated using different additive manufacturing technologies like binder jetting and powder bed fusion (Selective Laser Sintering, Electron Beam Melting, etc.) All the powders offered by GTP for the additive manufacturing market undergo exhaustive testing before and after sintering to confirm purity and density. For more information, please don't hesitate to contact one of our principle scientists.
