(EN) In one example in accordance with the present disclosure, an additive manufacturing build unit is described. The additive manufacturing build unit includes a vibrating bed on which a volume of build material is to be disposed. The bed is to vibrate to remove excess build material. A non-vibrating frame of the build unit supports the vibrating bed. The build unit also includes a bed-frame interface to: couple the vibrating bed to the non-vibrating bed frame, and isolate vibrations to the vibrating bed. A flexible seal of the build unit is disposed between the vibrating bed and non-vibrating frame. The flexible seal prevents build material from contaminating an additive manufacturing system in which the additive manufacturing build unit is disposed and allows relative motion between the vibrating bed and the non-vibrating frame.
(FR) La présente invention concerne, selon un exemple, une unité de construction de fabrication additive. L'unité de construction de fabrication additive comprend un lit vibrant sur lequel un volume de matériau de construction doit être disposé. Le lit doit vibrer pour éliminer le matériau de construction en excès. Un cadre non vibrant de l'unité de construction supporte le lit vibrant. L'unité de construction comprend également une interface cadre-lit pour : coupler le lit vibrant au cadre de lit non vibrant, et isoler les vibrations du lit vibrant. Un joint souple de l'unité de construction est disposé entre le lit vibrant et le cadre non vibrant. Le joint souple empêche le matériau de construction de contaminer un système de fabrication additive dans lequel l'unité de construction de fabrication additive est disposée et permet un mouvement relatif entre le lit vibrant et le cadre non vibrant.
