摘要： To provide a three-dimensional shaping method that allows defects in three-dimensional shaped products to be avoided, by rapidly detecting sintering defects, where the sintering step comprises the following operations:
a. measuring the width of the spark forming region generated on the sintering surface is photographed, and the light intensity of sparks,
b. commanding to continue sintering within the next time unit or the next powder layer forming step, when it has been detected that the region width and light intensity of the process a are within the standard ranges for a given time unit,
c. commanding to cancel sintering in the next time unit or the next powder layer forming step under judging that a sintering defect has occurred, when it has been detected that a condition has occurred in which the region width and light intensity of the process a deviate from the standard ranges for a given time unit.
Further, the sintering step comprises judging the cause of the sintering defect as related to beam control or powder surface, based on whether sintering region width/light intensity changes slowly or rapidly.

摘要： A method (100) includes receiving torque data (101) of a powder recoater operatively connected to an additive manufacturing system (200). The torque data includes torque data of the recoater when the recoater traverses a build area (205). Receiving torque data (101) includes receiving force data from a plurality of load cells, each load cell operatively associated with a blade segment of a recoater blade assembly. The method also includes determining a quality (103) of one or more of an additive manufacturing process (200) and/or product based on the torque data.

摘要： When an emission current is changed, a decrease in brightness of an electron beam is prevented. An electron gun includes a cathode that emits thermoelectrons, a Wehnelt electrode that focuses the thermoelectrons, a control electrode that extracts the thermoelectrons from a distal end of said cathode, an anode that accelerates the thermoelectrons and irradiates a powder with the thermoelectrons as an electron beam, and an optimum condition collection controller that changes at least one of a bias voltage to be applied to the Wehnelt electrode and a control electrode voltage to be applied to the control electrode, and decides a combination of the bias voltage and the control electrode voltage at which the brightness of the electron beam reaches a peak.

摘要： The invention relates to a method for the generative manufacturing of a component (21) (for example by selective laser melting) and an apparatus (11) which is suitable for implementing this method. In the apparatus, the component (21) is produced for example in a powder bed (13) by means of an energy beam (20), wherein the component (21) under construction is brought to a required temperature level by a heating device (24) integrated in a building platform (14). According to the invention, the heating power of the heating device (24) is lowered more and more as the process progresses, and so a reference temperature (T
r ) is maintained at the surface of the component (21) under construction. According to the invention, allowance is made here for the fact that the energy beam (20) introduces into the component (21) under construction an amount of heating power that cannot be dissipated quickly enough because of the thermal resistance of the component. The adaptation of the heating power is advantageously performed by means of an open-loop and/or closed-loop control (26).

摘要： A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.

摘要： Auf einen Untergrund wird eine Pulverschicht (8) aufgebracht. Mittels eines Prozessstrahls (12) werden lokal erste Teilbereiche (10) der Schicht (8) aufgeheizt, so dass sich die in den ersten Teilbereichen (10) befindlichen Körner des Pulvers (9) zwar erwärmen, aber noch nicht miteinander verbinden. Es wird ein Temperaturprofil der aufgebrachten Schicht (8) erfasst und in der Nähe des jeweiligen ersten Teilbereichs (10) als Funktion des Abstands (x) von dem jeweiligen ersten Teilbereich (10) und/oder der Zeit ausgewertet. Im Rahmen der Auswertung wird anhand des Temperaturprofils für den jeweiligen ersten Teilbereich (10) zumindest die lokale Wärmeleitfähigkeit (k) oder lokale Diffusivität (D) quantitativ oder qualitativ ermittelt. Mittels des Prozessstrahls (12) werden sodann lokal zweite Teilbereiche (11) der aufgebrachten Schicht (8), die die ersten Teilbereiche (10) zumindest teilweise überlappen, aufgeheizt, so dass sich die in den zweiten Teilbereichen (11) befindlichen Körner des Pulvers (9) miteinander verbinden. Mindestens eine die Aufheizung der zweiten Teilbereiche (11) beeinflussende Prozessgröße des Prozessstrahls (12) wird in Abhängigkeit von der zuvor für den zumindest überlappenden ersten Teilbereich (10) ermittelten lokalen Wärmeleitfähigkeit (k) oder Diffusivität (D) bestimmt.
