Automated powder removal system DPS Metal 1

metal powder

Unpack the build job from the build frame and completely de-powder both. The DPS Metal 1 makes this possible automatically, and in a single work operation, without the requirement for an operator to perform any intermediate manual steps. The cleaning result is so good that downstream cleaning activities are usually unnecessary. During the cleaning cycle the metal powder is collected in a container for subsequent reprocessing. The closed system protects personnel from the metal powder dust while equally protecting the metal powder from external environment contamination. The build frame is fed directly from the 3D printer into the station with the build job together with the excess metal powder contained within it. Loading can be carried out manually (e.g. by lift truck) or using an automatic transport system. The entire cleaning process takes place within a closed chamber either under atmospheric conditions or under inert gas. After inverting the build frame with the printed parts, cleaning nozzles use air jets (compressed air or inert gas) to remove excess powder from the components. This not only loosens the excess metal powder from the deepest crevices of the built component, but also removes the powder adhering to the build frame. The cleaning process is further enhanced by the use of a vibrator unit. The frequency-modulating vibrations introduced into the component break up any bridges formed in the metal powder. Optionally, in the DPS Metal 1 at the end of the cleaning process, the build job can either be removed from the build frame or left within it. Accordingly, they are subsequently unloaded from the station combined or separately.
