Abstract
A system includes a build platform having a bottom surface and a top surface. A plurality of apertures receives the build material on the build platform. A vibration generator is coupled to the build platform to vibrate the build platform and move the build material on the build platform. An air handler applies airflow to the build platform in a first airflow mode and a second airflow mode. In the first airflow mode, the build material from the build platform is removed through the plurality of apertures.
