ERIE -- Elementum 3D, a developer and supplier of groundbreaking metal additive manufacturing (AM) materials, announced the issuance of patents in the U.S., Canada, and Australia for its Reactive Additive Manufacturing (RAM) technology.
The RAM process significantly expands the potential AM materials library by enabling printing of previously unprintable materials, Elementum said.
Through this process, Elementum 3D has introduced a family of new laser powder bed fusion (LPBF) printing materials with superior properties compared to previously available AM materials and corresponding wrought alloys.
This success in fusing AM with innovative new materials and desirable-but-previously unprintable traditional manufacturing materials will propel the introduction of new and inventive AM applications, the company said.
Elementum 3D specializes in materials and process development. Its team leverages deep, specialized expertise to create advanced metal alloys, superalloys, and metal ceramic composites.
Elementum 3D uses RAM technology to create printable, high-performance alloy powders based on established wrought alloys, including aluminum 1000, 2024, 6061, 7050, and 7075.
Popular high strength wrought aluminum alloys could not previously be printed because they suffer hot tearing (solidification cracking), resulting in parts with very poor mechanical properties.
The RAM process forms sub-micron inoculants in the melt pool that nucleate aluminum grains to produce a fine equiaxed microstructure for good printability and exceptional performance.
By making AM versions of these alloys widely available, Elementum 3D eliminates material compromises and democratizes materials freedom, the company said.
