AML3D Limited, Edinburgh, Australia, has been granted an Australian patent for its Wire Additive Manufacturing (WAM®) process, a wire-based form of Directed Energy Deposition (DED), after an examination of its International Patent Portfolio. The patent is reported to provide coverage over the method and apparatus for additively manufacturing metal parts.
Key coverage items include:
- The method of manufacturing a metallic part in any weldable metal by solid freeform fabrication, enhanced by an atmospheric protection device and synergic heating and cooling apparatus
- The method of computer-generating three-dimensional models of parts, slicing the model into a set of parallel, sliced layers and then dividing each layer into a set of virtual, one-dimensional pieces and forming a direction specific, layered model of the part
- The method of uploading the direction-specific, layered model of the part into a welding control system, which additively manufactures the 3D metal part
“This is a significant milestone for our company and our journey,” stated Andrew Sales, Managing Director. “The granting of this patent is further validation of our technology, and also secures our position as a provider of a major 3D Printing process. The market demand for advanced wire feedstock Additive Manufacturing continues to accelerate, driven by the global pandemic. And international patent protection will further strengthen our position in a significant and growing addressable market.”
