Title (EN) VACUUM-ASSISTED INCIDENTAL BUILD MATERIAL COLLECTION WITH RECEPTACLE IN THREE-DIMENSIONAL PRINTER
(FR) COLLECTE DE MATÉRIAU DE CONSTRUCTION INDICENT ASSISTÉE PAR LE VIDE À L'AIDE D'UN RÉCEPTACLE DANS UNE IMPRIMANTE TRIDIMENSIONNELLE
Abstract:
(EN) The technology described herein includes a spreader that creates scattered incidental particles in a build chamber when spreading build material is applied in the build platform. One or more vacuum sources create negative pressure zones in one or more receptacles to collect the incidental particles in the build chamber during printing process and thus minimize the scattering of the incidental particles.
(FR) La technologie décrite dans la présente invention comprend un taleur qui crée des particules incidentes diffusées dans une chambre de construction lorsque le matériau de construction d'étalement est appliqué dans la plate-forme de construction. Une ou plusieurs sources de vide créent des zones de pression négative dans un ou plusieurs réceptacles pour collecter les particules incidentes dans la chambre de construction pendant le processus d'impression et réduisent ainsi au minimum la diffusion des particules incidentes.
