| description | The invention relates to a liquefier assembly (1) for an extrusion¬ based additive manufacturing system. The assembly includes a body (31), a filament passageway (34) through the body and a heating element (7) at least partially within the filament passageway. The heating element is operatively connected to circuitry configured to supply, in use, power directly to the heating element such that build material flowing along or through the filament passageway is heated by the heating element. In some examples, the circuitry is configured to supply a current to the heating elements (7). In other examples, the circuitry is configured to heat inductively the heating elements via heating coils.
L'invention concerne un ensemble liquéfacteur (1) destiné à un système de fabrication additive utilisant l'extrusion. L'ensemble comprend un corps (31), un passage de filament (34) à travers le corps et un élément chauffant (7) au moins partiellement à l'intérieur du passage de filament. L'élément chauffant est connecté de manière fonctionnelle à des circuits conçus pour fournir, lors de l'utilisation, de l'énergie directement à l'élément chauffant de sorte que le matériau de construction s'écoulant le long du passage de filament ou à travers ce dernier soit chauffé par l'élément chauffant. Selon certains exemples, les circuits sont conçus pour fournir un courant aux éléments chauffants (7). Selon d'autres exemples, les circuits sont conçus pour chauffer par induction les éléments chauffants par l'intermédiaire de bobines thermiques. |
