摘要： A calibration method for a system for powder bed-based generating of three-dimensional components by means of electromagnetic radiation, in particular such as a PBLS system, having a radiation source deflection unit and a raisable and lowerable carrier plate, above which a component is built, where, in order to calibrate the radiation source deflection unit, at least one virtual reference mark is used and, by means of a detector, a target-actual deviation between the virtual reference mark and a beam of the radiation source deflection unit is determined. An improved calibration method is achieved in that the at least one virtual reference mark is projected on a reference surface, which can travel vertically by means of the raisable and lowerable carrier plate, and independently of the vertical position thereof.

摘要： A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

摘要： This application describes a build plate having integrally formed channels for cooling the build plate during additive manufacturing or 3D printing. The build plate may include a bottom portion (e.g., base, section, half, etc.) and a top portion (e.g., top, section, half, etc.). The top portion is formed, via additive manufacturing, onto the bottom portion. The top portion includes channels that are configured to receive coolant, gases, or other fluids to provide cooling effects to the build plate during manufacturing of a part on the build plate. The use of the channels may result in increased heat dissipation, improved throughput, precision, and/or efficiencies in additive manufacturing.

摘要： A device and method are provided for evaluating the susceptibility of hot cracking in an additive manufacturing process. A first end of a substrate is interconnected to a base and one of the base and a deposition device is moved in a first direction and the second end of the substrate is pulled. A powder is dispensed at a selected rate and an energy bean having an adjustable power density is direct at the powder to melt the powder to form a material which is deposited as a layer of a material on the substrate. During the deposition process or during the deposition of the material on a subsequent substrate, one or more parameters/conditions are varied to determine the point at which hot cracking occurs during the deposition process.

摘要： A method of forming a three-dimensional printed part is disclosed, including ejecting a drop of print material from an ejector for a printing system in a substantially vertical trajectory, directing a stream of inert gas toward the drop of print material from a first direction, and diverting the drop of print material from the substantially vertical trajectory prior to the drop of print material landing onto a surface. The method includes directing a stream of inert gas toward the drop of print material from other directions. A printing system includes at least a first channel oriented in a first plane parallel to the substrate and positioned between the substrate and the ejector, and a gas supply connected to the first channel.

摘要： Methods of additively manufacturing a manufactured component and systems that perform the methods. The methods include determining an energy application parameter at an addition location on a previously formed portion of the manufactured component. The methods also include supplying a feedstock material to the addition location. The methods further include delivering, from an energy source and to the addition location, an amount of energy sufficient to form a melt pool of the feedstock material at the addition location. The amount of energy is based, at least in part, on the energy application parameter. The methods also include consolidating the melt pool with a previously formed portion to form an additional portion of the manufactured component. The delivering includes delivering the amount of energy to the addition location along an axis of incidence, and the energy application parameter includes a directionality parameter that is based on the axis of incidence.
