Abstract: In one example, an apparatus for supplying material to an additive manufacturing platform comprises a rotatable delivery module comprising a vane; and a plurality of distribution elements. In use, the rotatable delivery module is controllable to rotate the vane to a supply position to enable material to be supplied to an additive manufacturing platform from the vane. The vane and the plurality of distribution elements are arranged such that during the rotation: the vane provides a dose amount of material from a material supply module for supply to an additive manufacturing platform and at least one of the plurality of distribution elements distributes material within the material supply module so that the vane supplies a substantially uniform dose of material along the length of the vane to the additive manufacturing platform.

Abstract: An additive manufacturing machine (34) comprising a build material spreading system (2). The spreading system (2) has a moveable spreader (4) with an exterior surface (8) to spread build material. The spreading system (2) also has a heater (10) located separate from the spreader (4). The heater (10) has a heat dissipater (20) extending around the spreader (4) to retain, between the dissipater (20) and the spreader (4), air (36) heated by the dissipater (20).

Abstract: This build material spreading apparatus for additive manufacturing, includes a movable spreader, a build material dispenser, and a controller to calibrate the amount of build material needed to form a layer. The controller controls the build material dispenser to dispense a predetermined amount of build material. The controller controls the movable spreader to spread the dispensed build material to form a layer. The controller determines an amount of build material remaining after spreading. The controller modifies, based on the determined amount of remaining build material, the predetermined amount of build material to be subsequently provided by the build material dispenser.

Abstract: According to one example, there is provided apparatus for generating a three-dimensional object. The apparatus comprises a build material distributor movable bi-directionally in a first axis to deposit successive layers of a build material on a support, and an agent distributor movable bi-directionally in a second axis different to the first axis to deliver an agent onto selected portions of successive layers of build material.

Abstract: A controller may be to receive temperature data representing a temperature distribution of at least part of a current layer of build material that is measured by a temperature sensor. The controller may be to determine one or more weighting factors representing a degree of influence of each of one or more previous layers of the build material beneath the current layer on a property of the current layer. The controller may be to identify one or more regions in the current layer based on the one or more weighting factors and based on how the property is exhibited by each of the one or more regions. The controller may be to cause the current layer to achieve a target temperature if the temperature data in a selected region of the identified one or more regions does not match the target temperature.
