Additive manufacturing device with a heating device

An additive manufacturing device for manufacturing a solid article by a selective laser sintering application, the additive manufacturing device comprising a laser generation unit, a supply unit, a raw material container containing a raw material and having a raw material surface exposed to a laser beam to be generated by the laser generation unit in operation, a control unit wherein a heating device includes 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 to direct the laser beam onto the pre-heated raw material surface according to a computer generated model of the solid article stored in a storage unit associated with the control unit, wherein the laser beam generated by the laser generation unit passes through the heating surface onto the pre-heated raw material surface, wherein the heating surface continuously extends over the raw material surface, wherein the laser beam generated by the laser generation unit initiates the selective laser sintering application, and wherein the heating surface comprises a heating element embedded therein, such that the heating surface is heatable by the heating element and wherein a pressurizing device is configured to compress the raw material, wherein the pressurizing device includes at least one of the heating surface or the heating device.
