Title (EN) ELECTROMAGNETIC PRINT NOZZLE HAVING AN EXTRUDER FOR DIRECT-WRITE ADDITIVE MANUFACTURING
(FR) BUSE D'IMPRESSION ÉLECTROMAGNÉTIQUE À EXTRUDEUSE DESTINÉE À LA FABRICATION ADDITIVE À ÉCRITURE DIRECTE
Abstract:
(EN) A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material. An electro-magnetic heater is provided to heat and deposit molten working material as a new supply of working material is forced through the material guide. A single or twin screw extruder is provided within for advancing, mixing and/or depositing the working material through a tip positioned at an end of the material guide.
(FR) L'invention concerne un procédé et un appareil pour la fabrication additive qui comprend un guide de matériau pour diriger une alimentation en matériau de travail. Un dispositif de chauffage électromagnétique est présent pour chauffer et déposer le matériau de travail en fusion lorsqu'une nouvelle alimentation en matériau de travail est poussée dans le guide de matériau. Une extrudeuse à vis simple ou double est présente pour faire avancer le matériau de construction, le mélanger et/ou le déposer au moyen d’un embout positionné sur une extrémité du guide de matériau.
