Print and recoat assemblies for additive manufacturing systems and methods for using the same

A method for forming an object, the method comprising:

• moving a recoat assembly in a coating direction over a supply receptacle comprising build material, wherein the recoat assembly comprises a powder spreading member;
• contacting the build material in the supply receptacle with the powder spreading member;
• irradiating, with an energy source coupled to the recoat assembly, an initial layer of build material positioned in a build receptacle;
• and
• passing a gas over the energy source, thereby heating the initial layer of build material positioned in the build receptacle via forced convection.

An additive manufacturing system comprising:

• at least one of a print assembly and a recoat assembly;
• a housing assembly coupled to the at least one of the print assembly and the recoat assembly, the housing assembly comprising an energy source enclosure;
• an energy source positioned at least partially within the energy source enclosure;
• and
• an air distribution system in communication with the energy source enclosure, wherein the air distribution system comprises a pump structurally configured to pass a gas to the energy source enclosure to transfer thermal energy from the energy source.
