The present invention provides a method for altering the bead profile for using 3D printing to improve the shear strength of a so manufactured product by altering the bead height of adjacent beads or in adjacent layers such that either the height or the centers of the beads between adjacent layers are altered. This is achieved by either height reduction or by flow rates to alter the height or positioning of the beads by altering the bead profiles the shear strength between adjacent layers in the X-Y plane is improved. The present invention is equally applicable to increasing shear strength in the Y-Z plane or the X-Z plane as desired.

METHODS FOR IN SITU FORMATION OF DISPERSOIDS STRENGTHENED REFRACTORY ALLOY IN 3D PRINTING AND ADDITIVE MANUFACTURING
Methods of fabricating objects using additive manufacturing are provided using pretreated powders. In a first aspect, the methods create in situ dispersoids within the object to increase the oxygen content to between 500 ppm and 3000 ppm or to increase the nitrogen content to between 250 ppm and 1500 ppm. The pretreated powders are then formed into layers in an environmentally controlled chamber of an additive manufacturing machine. The quantity of refractory alloy powder is partially pretreated by exposure to the atmosphere for a selected period of time or in an inert atmosphere having oxygen and/or nitrogen introduced thereinto. The partially pretreated quantity of powder is then further pretreated in an inert atmosphere controlled chamber to raise the oxygen and/or nitrogen level to between about 250 ppm and 1000 ppm for nitrogen and between about 500 ppm and 2000 ppm for oxygen. The layers of pretreated powder are then exposed to a transient moving energy source or stationary energy source for melting and solidifying the layers; and creating in situ dispersoids in the layers. In a second aspect, carbon dioxide is introduced into an inert atmosphere controlled chamber having hafnium powder therein for creating hafnium carbide dispersoids throughout the object.

The present invention provides a fixture or device which is particularly adapted for installation within a confined compartment of an aircraft, such as a lavatory, galley or cockpit, and which emits UVC within safe limits, i.e., within prescribed safe wavelengths, irradiance, and times (below the ‘Actinic Dose’) while the compartment is occupied, to continuously disinfect the interior air and prevent transmission of not only viruses, but pathogens and the like. The device is preferably a triangular prism which houses a metal core pcBoard, a controller pcBoard and at least one support frame which are fabricated from a heat dissipating metal, as is the hypotenuse of the prism.
