1. An additive manufacturing device for manufacturing a solid article, comprising a laser generation unit and a build unit, wherein the laser generation unit is configured to emit a laser beam, wherein the build unit comprises a supply unit and a raw material container, wherein the raw material container contains a raw material, wherein the raw material is disposed with a raw material surface exposed to the laser beam emitted by the laser generation unit, wherein a heating device is arranged between the laser generation unit and the build unit, wherein the heating device is configured as a heating surface for heating the raw material surface to form a pre-heated raw material surface, wherein the laser generation unit is disposed with a directing unit configured to direct the laser beam onto the pre-heated raw material surface through the heating surface.
