High strength, oxidation resistant refractory alloys are difficult to fabricate for commercial use in extreme environments.
Commercial closed-cell insulation foam boards reduce their thermal resistivity by up to 30% due to gas diffusion in and out of foam cells.
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.
Moisture management accounts for over 40% of the energy used by buildings. As such development of energy efficient and resilient dehumidification technologies are critical to decarbonize the building energy sector.
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.
