Abstract: A metal powder additive manufacturing system and method are disclosed that use increased trace amounts of oxygen to improve physical attributes of an object. The system may include: a processing chamber; a metal powder bed within the processing chamber; a melting element configured to sequentially melt layers of metal powder on the metal powder bed to generate an object; and a control system configured to control a flow of a gas mixture within the processing chamber from a source of inert gas and a source of an oxygen containing material, the gas mixture including the inert gas and oxygen from the oxygen containing material.

Abstract: A system and method for three-dimensional printing are provided. One three-dimensional printing system includes a first printing surface configured to hold a first three-dimensional object. The three-dimensional printing system also includes a second printing surface configured to hold a second three-dimensional object. The three-dimensional printing system includes at least one printing head disposed adjacent to the first and second printing surfaces for printing the first and second three-dimensional objects. A vertical position of the first printing surface is controlled independently from a vertical position of the second printing surface.

Abstract: A detonation device cleaning system includes a vessel having a main body including an outer surface and an inner surface that collectively define an interior chamber. A detonation combustor cleaning device is mounted to the vessel. The detonation combustor cleaning device includes at least one combustion chamber that defines a combustion flow path. The at least one combustion chamber includes a deflection member arranged along the combustion flow path. An ignition device is operatively connected to the at least one combustion chamber. The ignition device is selectively activated to ignite fuel within the at least one combustion chamber to produce a shockwave that moves in a first direction along the combustion flow path, is redirected back along the flow path within the at least one combustion chamber, and passes into the interior chamber to dislodge particles clinging to the inner surface of the vessel.

Abstract: A detonation combustor cleaning device includes at least one combustion chamber having combustion flow path and including a deflection member. An ignition device is operatively connected to the at least one combustion chamber is selectively activated to ignite a combustible fuel within the at least one combustion chamber to produce a shockwave that moves in a first direction along the combustion flow path, impacts the deflection member, reverses direction and passes into a vessel to dislodge particles clinging to inner surfaces thereof.
