Abstract: An example of an additive manufacturing system is disclosed. The example disclosed herein comprises a controller. The controller is to generate a theoretical heatmap representing portions of a layer of build material heated during processing of a previously formed layer supplied to a build bed. The controller is also to calculate, based on the theoretical heatmap, an amount of build material needed in a next layer to be supplied to the build bed. The controller is further to instruct a supply module to supply the amount of build material to the build bed.

Abstract: In example implementations, an apparatus includes a storage unit, an auger screw, a housing enclosing the auger screw and at least one heater coupled to the housing. The augers screw receives a build material from the storage unit and delivers the build material to a build platform via movement of the auger screw. The build material is heated by the at least one heater as the build material is being moved by the auger screw.
