Abstract[English]
A print head (10) for a filament 3D printer (100) includes a channel (12) for guiding a polymer filament (50) through an outlet opening (12a), a heating block (14) in contact with the outlet opening (12a) of the channel (12) and configured to heat the polymer filament (50), a nozzle (20) having an outlet aperture (22), where the nozzle (20) is connected to the outlet opening (12a) of the channel (12) so that the polymer filament (50) passes through the outlet aperture (22), and the outlet aperture (22) of the nozzle (20) is arranged axisymmetrically around the nozzle (20) and located on a longitudinal axis (T) of the nozzle (20), and one or more air outlet openings (30) directed towards a meeting zone (P) defined by tips of the air outlet openings (30) and the outlet aperture (22) of the nozzle (20).[French]
L'invention concerne une tête d'impression (10) pour une imprimante 3D à filament (100) comprend un canal (12) pour guider un filament polymère (50) à travers une ouverture de sortie (12a), un bloc chauffant (14) en contact avec l'ouverture de sortie (12a) du canal (12) et configuré pour chauffer le filament polymère (50), une buse (20) présentant une ouverture de sortie (22), où la buse (20) est connectée à l'ouverture de sortie (12a) du canal (12) de sorte que le filament polymère (50) passe à travers l'ouverture de sortie (22), et l'ouverture de sortie (22) de la buse (20) est disposée de manière axisymétrique autour de la buse (20) et située sur un axe longitudinal (T) de la buse (20), et une ou plusieurs ouvertures de sortie d'air (30) dirigées vers une zone de rencontre (P) définie par les pointes des ouvertures de sortie d'air (30) et l'ouverture de sortie (22) de la buse (20).
