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 three-dimensional 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 machining process.
Additive Manufacturing
GTP developed tungsten 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 or Electron Beam Melting).
There are numerous advantages to the AM process, including:
- Processing of complex parts to near net shape
- Minimizes need for expensive tooling
- Reduces prototyping costs
- Faster from prototype to production Potential to create distinctive alloys or microstructures
- Smaller environmental footprint
- Production is easily adapted to a change in the printed part
- Lighter weight alternative to solid parts
