Copper 3D Printing with Powder Bed Fusion Technology

Copper is high in reflectivity and thermal conductivity which makes it difficult to process using lasers. This copper 3D printing technology leverages powder bed fusion (PBF) and advanced high-powered laser to selectively fuses metal powder layer by layer. This enables the precise fabrication of intricate copper component while preserving the material's mechanical strength and conductivity. This technology enables superior design freedom, allowing small features and internal structures that is otherwise impossible to achieve with conventional copper manufacuturing methods.

The technology owner is seeking for industry use cases for co-development. 

Copper 3D printing with powder bed fusion technology enables precise, high-density copper printing with enhanced thermal and electrical properties. The system support a build volume of 250 x 250 x 325 mm.
