Abstract: An additive manufacturing method comprises the steps of using an additive manufacturing technique to manufacture a product (10), at least part of which is supported by a support (12) formed integrally with the product (10) as part of the additive manufacturing technique, wherein the support (12) comprises a plurality of support beams (16) which, when finished, extend continuously to substantially interconnect the part with a support table (18), the beams (16) intersecting one another to form a lattice, and separating the support from the product, wherein the lattice is of irregular form.
