Zusammenfassung:	A varying a composition of build material used for a three dimensional (3D) part formed by a 3D printer are disclosed. In a system provided, a number of vessels for build material are included, wherein each vessel includes a feeder coupled to a conveying system. The conveying system conveys and blends build material from the vessels. A controller is configured to adjust a composition of the build material by adjusting an amount of material added from each of the vessels by controlling the feeder on each of the vessels.
