Hewlett Packard Multi Jet Fusion Powder based 3D Printer

I worked on the sub-module that delivered the powder material onto a plate to the build chamber to be spread by a roller. Through concept design, prototyping and detailed testing, a carriage box was designed to be dosed with powder and then moved along a plate leaving a perfectly uniform layer of powder. This layer of powder would be uniform in density and thickness to provide a reliable and predictable amount for each layer of the build volume. The carriage was attached to a bracket that moved along a linear rod. It was translated via a motor driven belt and pully system.
