description Apparatus and methods for additive manufacturing with variable extruder profiles are described herein. An extruder print head with multiple nozzles placed at different angles allows for additional degrees of freedom to additively manufacture parts with complex shapes. In addition with the use of shape memory alloy materials, the diameter of one or more nozzles can be adjusted during the additive manufacturing process. This allows for independent control of the build resolution and of the build rate.
