摘要： A nozzle for producing material extrusion in a three-dimensional printer includes a shank including an internal flow passage, where the shank is constructed of a first material having a first thermal conductivity. The nozzle also includes a shank barrel mechanically coupled to the shank. The shank barrel is constructed of a second material having a second thermal conductivity. The first thermal conductivity of the first material is different from the second thermal conductivity of the second material to create a first heat break between the shank and the shank barrel, where the first heat break reduces heat transfer between the shank and the shank barrel.

摘要： A three-dimensional printer and a method of leveling a support surface in a three-dimensional printer. The three-dimensional printer includes a base plate, a support bed, including a support surface, wherein the support bed is mounted to the base plate, a plurality of adjustable mounting assemblies adjustably mounting the base plate to the support bed, wherein each adjustable mount assembly separates the base plate from the support bed by a first distance. The three-dimensional printer may further include a vacuum port fluid communication with a vacuum opening, a vacuum pump in fluid communication with the vacuum port, a vacuum regulator coupled to the tubing between the vacuum pump and vacuum port, and a vacuum pressure switch coupled to the tubing between the vacuum regulator and the vacuum port.
