A method and apparatus for manufacturing comprises forming a shell having a support structure located in a cavity which is filled with a curable filler material to form a tool. The shell and the support structure may be formed using an additive manufacturing system (such as fused deposition modelling, selective laser sintering and stereolithography) from a design of a tool. Preferably the tool is used to lay up and cure a number of composite materials to form a part for an aircraft. The filler may be an epoxy, a thermally conducting epoxy, a polymer or a cement and the shell and support structure may be formed from a plastic, a metal, a thermal plastic, acrylonitrile butadiene styrene, or a polycarbonate. A data processing system may be used to create a design of the tool from an original part in which the design is scaled to take into account changes in dimensions of the shell caused by curing. |
