Abstract: In one example, a non-transitory processor readable medium with instructions thereon that when executed cause an additive manufacturing machine to: form a first layer of build material; form a second layer of build material over the first layer; solidify build material in the second layer to form a slice; and form a barrier that is separable from the slice to prevent a coalescing agent in the second layer penetrating build material in the first layer.
