Abstract
(DE)
Ein Verfahren zum Entfernen einer Stützstruktur (18) in einem durch additive Fertigung hergestellten Bauteil (10) sieht vor, dass in eine Druckkammer (28) eingebrachtes explosives Gas gezündet wird, wobei zusätzlich in der Kammer noch eine Gasführungseinrichtung vorgesehen ist, mit der die Flammfront in den Hohlraum (12) geleitet wird. Zudem ist ein Werkzeug zur Durchführung des Verfahrens angegeben.
(EN)
The invention relates to a method for removing a support structure (18) in a component (10) produced by additive fabrication, according to which method explosive gas introduced into a pressure chamber (28) is ignited, a gas guiding device by which the flame front is directed into the cavity (12) being additionally provided in the chamber. The invention further relates to a tool for carrying out the method.
(FR)
L'invention concerne un procédé destiné à éliminer une structure de support (18) dans une pièce (10) réalisée par fabrication additive, selon lequel un gaz explosif introduit dans une chambre de pression (28) est enflammé, un dispositif de guidage de gaz permettant de guider le front de flamme dans la cavité (12) étant en outre agencé dans la chambre. L'invention concerne par ailleurs un outil destiné à la mise en œuvre du procédé.
