Abstract: 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.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing platform is described. The additive manufacturing platform 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 and operates in at least two extraction modes during a build material extraction period. The additive manufacturing platform also includes a non-vibrating frame to support the vibrating bed.

Abstract: A build material recovery system for a three-dimensional (3D) printer can include a selective solidification device to create a 3D object using build material, a build processing device to separate the 3D object from unfused build material, a material separating and conditioning device to condition the unfused build material, and a material storage device to store the conditioned build material.

Abstract: A three-dimensional printing system may include a build platform, the build platform including at least one hole defined through the build platform, a diffuser plate placed below the at least one hole to maintain an amount of build material between a lower surface of the build platform and an upper surface of the diffuser plate, and a flow channel defined around the diffuser plate and sealing the diffuser plate from atmosphere.

Abstract: A build unit may include a build chamber, at least two datum apertures defined in at least two opposite sides of the build unit, and at least two alignment posts that seat within the datum apertures to couple the lift system to the build chamber, and to align the lift system in a first coordinate direction relative to the build chamber.
