Latest Patents
One of his latest patents is focused on infrared radiation sensing and beam control in electron beam additive manufacturing. This invention provides apparatuses for dynamically sensing infrared (IR) radiation in an electron beam powder bed fusion (EB-PBF) printer. The design includes a radiation collector that receives radiation from the surface of the powder bed, an IR-transparent material that rejects non-IR wavelengths, and a lens that focuses the IR radiation onto an optical fiber. The IR radiation is then carried from the vacuum chamber of the printer to a sensor, where IR information is determined based on the received radiation. This information can be utilized by the print controller to modify parameters such as beam intensity or scanning rate in real-time or during subsequent print cycles. Additionally, an occlusion member can selectively block or expose the radiation collector to protect it from condensation of vapor from vaporized particles at high temperatures.
Another notable patent involves a method of stabilizing a photohardening inhibitor-permeable film in the manufacture of three-dimensional objects. This method and apparatus allow for the solidification of a photohardenable material while admitting a photohardening inhibitor through a flexible film. This creates a 'non-solidification zone' where little or no solidification occurs, preventing the exposed surface of the photohardenable material from solidifying in contact with the film. The invention addresses the deformation of the film along the build axis, which can distort the resulting three-dimensional object. An apparatus is provided to stabilize the flexible film and minimize such deformation.
