  • Preheating of material in an additive manufacturing apparatus
    Patent number: 11485083
    Abstract: An additive manufacturing apparatus is disclosed. The apparatus includes a build platform, a scanning unit and a preheating arrangement. Material is operatively deposited on the build platform to form a material bed, with a surface of the material bed defining a material area. The scanning unit is configured to consolidate deposited material in a scan area on the surface of the material bed, wherein the scan area forms part of and is substantially smaller than the material area. The preheating arrangement is configured to focus energy onto the surface of the material bed substantially in the scan area and not in the remainder of the material area. A method of preheating material in an additive manufacturing apparatus, a method of forming an object by additive manufacturing and a preheating arrangement for an additive manufacturing apparatus are also disclosed.
