Latest Patents
Freitag holds a patent for a method titled "Laser-directed fabrication of full-density metal articles using hot." This invention discloses a process for fabricating a fully-dense three-dimensional metal article. The first embodiment involves forming the interior portion of the article through selective laser sintering in a layer of powder. After forming this layer, a laser is directed to create a gas-impervious skin around the interior portion. This process is repeated until the article is complete. The article, now surrounded by the skin, undergoes hot isostatic pressing to densify it. The skin, which acts as a 'can' during this process, may be removed or retained based on preference. The second embodiment describes forming the can first through laser generation, followed by filling it with metal powder before hot isostatic pressing.
