Abstract
In one example, a method of fabricating a three-dimensional object includes depositing a layer of build material, depositing a coalescing agent onto the layer of build material according to a slice of three-dimensional model data, irradiating the coalescing agent with microwave radiation such that the coalescing agent converts the microwave radiation into heat to coalesce the build material in which the coalescing agent was deposited.
Claims15
A method of fabricating a three-dimensional object, comprising:
- depositing a layer of build material;
- depositing a coalescing agent onto the layer of build material according to a slice of three-dimensional model data;
- and
- irradiating the coalescing agent with microwave radiation such that the coalescing agent converts the microwave radiation into heat to coalesce the build material in which the coalescing agent was deposited;
- wherein irradiating the coalescing agent comprises irradiating the coalescing agent with a first microwave radiation to partially coalesce the build material prior to irradiating the coalescing agent with a second relatively more intense microwave radiation to fully coalesce the build material.
