Zusammenfassung:	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).
