Abstract
A method of manufacturing an object is disclosed. Material is extruded from an extrusion head onto a tool, the extrusion head having an extrusion axis along which the material flows as it exits the extrusion head. Relative movement is generated between the extrusion head and the tool as the material is extruded so that the material is deposited as a series of layers, wherein the material cures on or after deposition so that the layers are fused together. The extrusion and the relative movement are controlled so that the series of layers are shaped in accordance with a stored three-dimensional model of the object. At least some of the layers are non-planar layers.
