摘要:
A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.
