摘要： Systems and methods for developing tough hypoeutectic amorphous metal-based materials for additive manufacturing, and methods of additive manufacturing using such materials are provided. The methods use 3D printing of discrete thin layers during the assembly of bulk parts from metallic glass alloys with compositions selected to improve toughness at the expense of glass forming ability. The metallic glass alloy used in manufacturing of a bulk part is selected to have minimal glass forming ability for the per layer cooling rate afforded by the manufacturing process, and may be specially composed for high toughness.

摘要： An arrangement for adjusting a powder flow in relation to the central longitudinal axis of an energy beam for a working head which is formed for powder application welding. There is a device for the two-dimensional or three-dimensional alignment of the powder supply in relation to the central longitudinal axis of the energy beam in a plane oriented at right angles to the central longitudinal axis of the energy beam. From one side, a linear beam is directed to the region in which the particles of the powdery material meet one another. At right angles thereto, there is arranged an optical detector array for locally resolved detection of intensities connected to an electronic evaluation unit designed to determine the shape, size and/or length of an irradiated region in which locally resolved intensities which exceed a predefinable threshold have been detected with the optical detector array. The irradiated region reaches from the surfaces of particles which the laser beam strikes with reduced power during the adjustment as far as a sub-region of the irradiated region which is arranged in the direction of a workpiece surface of accelerated powdery particles, in which the particles heated by the laser beam move divergently.

摘要： A temperature control method for additive manufacturing includes directing an energy beam of a first energy source toward a material and fusing at least a portion of the material to form a cladding layer, forging the cladding layer with a micro-forging device, and detecting a first internal effect parameter of the cladding layer at a forging position where is forged by the micro-forging device. The first internal effect parameter includes at least one of a stress or a strain of the cladding layer. The method also includes calculating a first calculated temperature of the cladding layer at the forging position based on the first internal effect parameter and adjusting the at least one of the first energy source and the micro forging device if the first calculated temperature does not fall within a desired temperature range.
