For example, a controller that regulates a deformation of at least a portion of the 3D object. The control may be in situ control. The control may be real-time control during the 3D printing process. For example, the control may be during a physical-attribute pulse. The present disclosure provides various methods, apparatuses, systems and software for estimating the fundamental length scale of a melt pool, and for various tools that increase the accuracy of the 3D printing.

Abstract: An apparatus and method for performing an ALM process is described. A first energy beam source (1) provides an energy beam (1b) which selectively melts a substrate powder (3) into a melt pool. A second energy beam source (2) provides an energy beam (2b) to heat condition substrate powder proximate to the melt pool. The path of the second energy beam (2b) is controlled by a controller (6) to oscillate independently of the path followed by the first energy beam (1b). The method may be applied to control and optimise heating and cooling rates of the sintered substrate during the ALM process enabling its microstructure to be controlled to suit the end use of the product and reduce the occurrence of residual stresses and consequent crack propagation.

Abstract: The invention relates to a device and a method for the additive manufacture of components through the layered bonding of powder particles to one another and/or to a semi-finished product or substrate already produced, using selective interaction of the powder particles with a high-energy beam, wherein, during the bonding of the powder particles into a layer made of powder particles with the aid of the high-energy beam, a gas flow, which has a flow direction having a directional component directed at least partially parallel to the layer of powder particles, is provided across the layer of powder particles and/or the bonding region in the layer of powder particles, wherein the directional component of the gas flow directed at least partially parallel to the layer of powder particles during the bonding of the powder particles in a layer is generated in at least two directions, which have oppositely directed directional components.
