Abstract: A powder removal assembly includes a build module comprising module sidewalls and a moveable build plate slidably coupled to the module sidewalls, and an extraction housing removably engaged with the module sidewalls of the build module and defining a turbulence chamber between the build module and the extraction housing. The extraction housing includes one or more sidewalls comprising one or more sidewall fluid flow channels extending through the one or more sidewalls and a top wall coupled to the one or more sidewalls, wherein the one or more sidewall fluid flow channels extend from a position proximate a base of the one or more sidewalls to the top wall.
