A manufacturing system, the manufacturing system comprising: an additive manufacturing assembly configured to at least partially form a first build component via an AM process; a milling assembly configured to at least partially form a second build component via a milling process; and a coolant supply system configured to selectively supply a coolant to each of the AM assembly and the milling assembly; wherein the AM assembly includes a support assembly that supports the first build component and that is in thermal communication with the first build component as the first build component is manufactured, and wherein the coolant supply system is configured to remove heat from the support assembly as the first build component is manufactured by flowing the coolant through at least a portion of the support assembly to regulate a temperature of the first build component as the first build component is manufactured; characterised in that the coolant supply system further includes a coolant supply system controller configured to generate and transmit a control signal to at least partially control a flow of the coolant through the coolant supply system, wherein the manufacturing system is configured to operate in a manufacturing mode that is one of an AM manufacturing mode, in which the AM assembly operates to at least partially form the first build component, and a milling manufacturing mode, in which the milling assembly operates to at least partially form the second build component, and wherein the coolant supply system controller is configured to selectively direct the coolant to one of the AM assembly and the milling assembly based, at least in part, on the manufacturing mode of the manufacturing system; wherein the coolant supply system further includes one or more coolant valves configured to selectively restrict the flow of the coolant through at least a portion of the coolant supply system, and wherein the coolant supply system controller is configured to actuate at least one of the one or more coolant valves to selectively direct the coolant; wherein the coolant supply system controller is configured such that, when the manufacturing system is in the AM manufacturing mode, the coolant supply system controller actuates the at least one of the one or more coolant valves to direct the coolant to the support assembly to regulate the temperature of the first build component; and wherein the coolant supply system controller is configured such that, when the manufacturing system is in the milling manufacturing mode, the coolant supply system controller actuates the at least one of the one or more coolant valves to direct the coolant to the milling tool coolant conduit to regulate a temperature of the milling tool. an additive manufacturing assembly configured to at least partially form a first build component via an AM process;
