In additive printing that utilizes multiple robotic agents to build, each agent, or arm, is currently limited to a prescribed path determined by the user.
This invention discusses the methodology to calibrating a multi-robot system with an arbitrary number of agents to obtain single coordinate frame with high accuracy.
High strength, oxidation resistant refractory alloys are difficult to fabricate for commercial use in extreme environments.
Gas metal arc welding (GMAW) wire arc additive manufacturing (WAAM) processes use inert shielding to protect the weld arc during material deposition, but do not protect the trailing bead, which can lead to weld issues varying from low finish quality to diminished material prop
As additive manufacturing technologies advance and 3D-printers get larger, there is a constant need for larger extruders with higher throughput to construct larger objects at reasonable time.
ORNL has developed a new hybrid additive manufacturing technique to create complex three-dimensional shapes like air foils and wind generator blades much more quickly.
