Methods of treating fused build material in an additive manufacturing system are described. The method includes a first treatment process comprising: depositing unfused build material over the fused build material in a working area of the additive manufacturing system, thereby providing a first build material layer; and supplying energy from a first energy source to the first build material layer to heat but substantially not fuse the unfused build material of the first build material layer.
