- the turbine blade can be produced in layers in a particularly simple and thus advantageous manner.
- a first powder layer is melted locally by means of an energy beam to form a first blade layer; subsequently it, so in this first shovel ⁇ layer, layer by layer brought listed more powder coatings which are melted locally in each case to form further blade layers.
- the turbine blade is formed by a plurality of stacked individual layers.
- the liquid layers may be used, which are hardened locally by means of an energy beam so that the turbine blade is assembled in this manner of layers instead of powder layers.
- the turbine blade is particularly preferably produced in a metal ⁇ metallic powder bed with an electron beam or laser beam.
- the laser or electron beam serves to selectively melt the thin powder layers, which form the turbine blade after cooling.
- CAD data are processed which describe the three-dimensional turbine blade by means of a volume model or a surface model.
- CAD data are converted prior to or during the additive manufacturing process is preferably in ⁇ layer data, where each layer corresponds to a cross-section of the turbine blade with finite thickness.
- the cross-sectional geometry of the turbine blade is preferably produced during the additive manufacturing process by a line-like exposure of the outer contours and a planar exposure of the cross sections to be filled.
- the line-like exposure is realized in the case of a point-shaped characteristic of the energy beam, preferably by a corresponding beam movement.

- Turbines for example steam or gas turbines, can have a multiplicity of turbine blades of various types.
- turbines comprise in many cases shovel Leit ⁇ that are similar to the blades shaped and non-rotating or static for example, may have the shape of a support surface. Guiding blades serve primarily to specifically direct the flow of the flow medium within the turbine.
- turbines may include compressor blades for a compressor section of the turbine. For this reason, it is considered advantageous when a rotor blade, a vane or a compressor blade for a Kom ⁇ pressorabêt of the turbine is made as part of the additive manufacturing process as a turbine blade.

- the separate by a cavity blade walls, at least portion ⁇ be connected to one another by lattice structures in order to achieve through the grating structures a support of the blade walls with each other.
- the suction-side blade wall of the turbine blade and the réellesei ⁇ term blade wall of the turbine blade are connected by a entspre ⁇ sponding grating structure at least in sections with each other to increase the stability of the turbine blade as a whole.
- At least one drainage slot is produced in the turbine blade within the scope of the additive manufacturing method.
- Such drainage slots are preferably to ver ⁇ turns, water which is condensed out of the current flowing through the turbine steam flow to dissipate from the near-wall flow of the flow medium.
- the ent ⁇ stationary wall by the condensation drops can lead to erosion damage to the rotor blades of the turbine in subsequent turbine stages.
- erosion damage can be reduced if - as proposed - drainage slits are provided, with which the size of the water droplets can be reduced. Thereby, the water droplets undergo a greater velocity and therefore a smaller Relativgeschwindig ⁇ ness to the rotational movement of the rotor blades, whereby the erosion damage is reduced by the water drops.
- the drainage slots are located near the trailing edge of the turbine blade.
- the drainage slots are in the trailing edge of the next third of the pressure-side blade wall.
- the drainage slots are located, for example, in the front third of the leading edge.
- Arranging drainage slots particularly close to the trailing edge becomes possible if a grid structure is provided within the turbine blade, since in such a case a particularly thin blade wall thickness can be used.
- a grid structure is provided within the turbine blade, since in such a case a particularly thin blade wall thickness can be used.
- other characteristics of the turbine can be realized ⁇ scoop during the additive manufacturing process: For example, Behei ⁇ wetting openings for reduction of the water drops in the turbine and / or other holes in the blade wall made ⁇ the.
- the heat transfer between the heating or cooling medium inside the blade is favored by the lattice structure and its large surface area.
- drainage slots Heating with ⁇ openings, other holes or other openings are at least partially provided with grating structures through which a Support takes place.
- the invention also relates to a turbine blade.
- a turbine blade According to the invention in this respect is provided in that between the blade walls of the turbine blade is a cavity, which is at least partially filled with a Git ⁇ ter Design.
- a significant advantage of the turbine blades according to the invention is the fact that it has a high stability with low weight.
- the turbine blade is a vane, a rotor blade or a compressor blade.
- the suction-side blade wall of the turbine blade and the pressure-side blade wall of the turbine show ⁇ fel are connected together by the lattice structure.
- Such a connection can be a support of the blade walls reach each other and thus ensure a particularly high stability.
- vane walls have openings or holes, these are preferably with a lattice structure - provided - partially ⁇ minimum.
- the invention further relates to a turbine, especially a gas turbine or steam turbine, which is, out ⁇ equipped with at least one turbine blade, as described above.
- the turbine blade within the turbine preferably forms a static guide vane, a rotating rotor blade or a compression vane.

- the turbine blade 10 is shown according to figure 1 in cross-section ⁇ .
- the pressure-side blade wall 30 Tur ⁇ depicted of 10 according to Figures 1 and 2 in the plan view in further detail.
- the blade ⁇ wall 30 has two slotted holes 100 and 110 has.
- the slot-shaped holes can serve as drainage slots and / or heating openings, with which water is removed from the near-wall flow of the turbine flowing through the flow medium.
- the arrangement of the slot-shaped holes 100 and 110 is selected such that they are as close as possible to the trailing edge 40, ie the leading edge 50 as far as possible. Particularly be ⁇ vorzugt the slot-shaped holes 100 and 110 are arranged within the trailing edge 40 facing half A of the pressure-side blade wall 30th
