Laser Powder Bed Fusion

3D printing of e.g. pure copper with laser powder bed fusion (LPBF) using a blue ultra brillant diode laser

Laser Powder Bed Fusion (LPBF) - The Process

Laser Powder Bed Fusion (LPBF) is a 3D printing process where a laser selectively fuses regions of a powder bed to build complex metal parts layer by layer. Conventionally, LPBF systems use infrared (IR) fiber lasers, typically operating at wavelengths around 1060–1080 nm, optimized for metals and alloys like titanium, steel, inconel and others. Using blue ultra-brilliant blue diode lasers in LPBF represents a new and emerging approach with several promising advantages, especially for materials that reflect IR and absorb visible blue wavelength (~445 nm), such as copper, gold and others.

Advantages of Laser Powder Bed Fusion with Blue Ultra Brillant Diode Lasers

  • High focusability on complex structures
  • Improvement of Laser Powder Bed Fusion processes of non-ferrous metals, especially copper
  • High efficient process with results of high quality

Application Examples for Laser Powder Bed Fusion (LPBF)

Powder Bed Fusion of Pure Copper

With 350 W laser power and a small spot size very thin layers are 3D printed. The result is a very small component of 21 mm x 21 mm x 10 mm out of 250 pure copper layers.
