A device for manufacturing a solid article includes a beam generation unit, a control unit, a supply unit, a container containing a raw material arranged in multiple raw material layers arranged upon each other, such that a raw material surface is exposed to a beam. The beam is emittable by the beam generation unit according to instructions of the control unit. A heating surface heats the raw material surface to form a pre-heated raw material surface. The beam generation unit is disposed with a directing unit to direct the beam onto the pre-heated raw material surface. The beam generated by the beam generation unit passes through the heating surface onto the pre-heated raw material surface. The beam generation unit and/or the directing unit is movable relative to the raw material surface, such that the angle of the beam relative to the raw material surface substantially remains constant.
