3Druck.com - Infinite Flex Introduces Pure Copper Powder for 3D Printing

The German company Infinite Flex presented a pure copper powder that can be easily processed in additive manufacturing with standard SLM systems.

Pure copper is a highly sought-after metal in almost all branches of industry. The reason for this is the high electrical and thermal conductivities of pure copper. Unfortunately, pure copper can usually not be used in additive manufacturing because the coupling of IR laser radiation with pure copper hardly works at all. This is mainly due to the strong reflection of the laser radiation and the high thermal conductivity of pure copper.

To the article

INFINITE POWDER CU 01 uses a patent-pending post-treatment of copper powder. This process, specially developed for additive manufacturing, makes a problem-free 3D printing of copper with all common standard infrared lasers possible in the first place.

Applications

  • Selective laser sintering (SLM)
  • Laser application welding (LMD)
  • Plasma Metallization / Digital Direct Metallization (DDM)

Electrical and thermal conductivity

  • Electr. Conductivity > 52 MS/m (91% IACS)
  • Therm. Conductivity > 360 W/(m*K)
