Abstract
A method of making a part includes the steps of: securing a build platform to an actuator which is disposed in a build chamber, depositing a powder onto the build platform; directing a beam from a directed energy source to fuse the powder; moving the actuator vertically downward within the build chamber by a layer increment of powder; repeating in a cycle the steps of depositing, directing, and moving to build up the part in a layer-by-layer fashion until the part is complete; lifting the build platform away from the actuator to create an opening therebetween; and evacuating the powder from the build chamber through the opening.
