A three-dimensional (3D) printer and method of additive manufacture are disclosed. The method includes building a three-dimensional (3D) object via a 3D printing process. After the 3D printing process, the 3D object is contained within a cake comprising the 3D object and partially fused excess build material. The method further includes vibrating the cake to loosen the excess build material. The frequency of the vibration is swept across a predetermined range of frequencies over a predetermined sweep interval.

Removal of excess build material in additive manufacturing

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.

Build material extraction using vibration and airflow

In an example implementation, a method of extracting three-dimensional (3D) objects includes forming on a vibratory extraction platform, a build cake comprising a fused 3D object encased within build material and vibrating the extraction platform to break apart the build material and sift it through openings in the extraction platform.
