The invention discloses liquefier assemblies for additive manufacturing systems, and methods of use thereof. According to the invention, a liquefier assembly (20) is intended for use in an additive manufacturing system (10) to print three-dimensional parts (12). In one aspect, the liquefier assembly (20) includes a liquefier (52) that is transversely compressible, and having an inlet end (64) configured to receive a consumable material (48) in a solid or molten state and an outlet end (66), a nozzle (56) at the outlet end, and an actuator mechanism (62) configured to transversely compress and expand the liquefier (52) in a controlled manner. In another aspect, the liquefier assembly (20) is self heating. 本发明提供了种用于在增材制造系统(10)中打印三维部件(12)的液化器组件(20)。在个方面，液化器组件(20)包括：液化器(52)，其可横向压缩并且具有配置成接收固态或熔融状态的消耗材料(48)的入口端(64)和出口端(66)；位于出口端处的喷嘴(56)；以及致动器机构(62)，其配置成以受控方式使液化器(52)横向压缩和膨胀。在另个方面，液化器组件(20)是自加热的。
