3D PRINTING SYSTEM WITH CYLONE SEPARATOR
According to examples, a 3D printing system may include a feed line to receive build material particles from a material bin, an air pressure generator to generate airflow inside the feedline to move the build material particles through the feedline, and a cyclone separator to receive the airflow and...

| description | According to examples, a 3D printing system may include a feed line to receive build material particles from a material bin, an air pressure generator to generate airflow inside the feedline to move the build material particles through the feedline, and a cyclone separator to receive the airflow and the build material particles from the feed line and to separate the build material particles from the airflow. The cyclone separator may include a chamber wall, a build material particle discharge opening, and a tapered wall connecting the chamber wall and the build material particle discharge opening. In addition, a ratio between a diameter of the chamber and a diameter of the discharge opening may be between about 1.5 and about 4.0.
Selon des exemples, la présente invention concerne un système d'impression 3D qui peut comprendre une ligne d'alimentation pour recevoir des particules de matériau de construction depuis un compartiment de matériau, un générateur de pression d'air pour générer un flux d'air à l'intérieur de la ligne d'alimentation pour déplacer les particules de matériau de construction à travers la ligne d'alimentation, et un séparateur à cyclone pour recevoir le flux d'air et les particules de matériau de construction depuis la ligne d'alimentation et séparer les particules de matériau de construction du flux d'air. Le séparateur à cyclone peut comprendre une paroi de chambre, une ouverture d'évacuation de particules de matériau de construction, et une paroi effilée reliant la paroi de chambre et l'ouverture d'évacuation de particules de matériau de construction. De plus, un rapport entre le diamètre de la chambre et le diamètre de l'ouverture d'évacuation peut être compris entre environ 1,5 et environ 4,0. |
