Title (EN) METHOD OF ADDITIVELY MANUFACTURING A STRUCTURE ON A PRE-EXISTING COMPONENT OUT OF THE POWDER BED
(FR) PROCÉDÉ DE FABRICATION ADDITIVE D'UNE STRUCTURE SUR UN COMPOSANT PRÉEXISTANT EXTERNE AU LIT DE POUDRE
Abstract:
(EN) Method of additively manufacturing a structure on a pre- existing component out of the powder bed A method of additive manufacturing a structure (1) on a pre- existing component (2) is provided, the method comprising disposing the pre-existing component (2) in a bed of powdery base material (3) and levelling the component (2), such that a manufacturing plane (MP) of the component (2) can be re- coated with the base material (3) and alternatingly recoating and irradiating the manufacturing plane (MP) with an energy beam (4) in order to additively build up the structure (1), wherein the irradiation is carried out in that the manufac- turing plane (MP) is scanned by the beam (4) in a non- continuous way, wherein - for the irradiation according to a second vector (V2) for the structure (1) - the beam (4) is either only guided parallel with respect to a previous first vector (V1), or the irradiation process is paused after the irradiation of the first vector (V1) for a time span between 1/10 second to 2 seconds until the irradiation is continued with the second vector (V2). Further, a novel apparatus is presented.
(FR) La présente invention concerne un procédé de fabrication additive d'une structure (1) sur un composant préexistant (2), le procédé comprenant les étapes consistant à disposer le composant préexistant (2) dans un lit de matériau de base pulvérulent (3) et mettre à niveau le composant (2), de telle sorte qu'un plan de fabrication (MP) du composant (2) peut être revêtu de nouveau avec le matériau de base (3) et, en alternance, revêtir à nouveau et exposer le plan de fabrication (MP) au rayonnement d'un faisceau d'énergie (4) afin de constituer de manière additive la structure (1), l'exposition au rayonnement étant réalisée en ce que le plan de fabrication (MP) est balayé par le faisceau (4) de manière non continue, - pour l'exposition au rayonnement selon un second vecteur (V2) pour la structure (1) - le faisceau (4) et soit uniquement guidé parallèlement à un premier vecteur précédent (V1), soit le processus d'exposition au rayonnement est mis en pause après l'exposition au rayonnement du premier vecteur (V1) pendant une durée comprise entre 1/10 de seconde et 2 secondes jusqu'à ce que l'exposition au rayonnement soit poursuivie avec le second vecteur (V2). La présente invention concerne en outre un nouvel appareil.
