DETAILED DESCRIPTION

[0049] At least one device (2) enabling the implementation of a metal additive manufacturing method comprises at least one raw material (H) suitable for use in the metal additive manufacturing method, at least one feeder (3) located on the device (2) and enabling the raw material (H) to be deposited, at least one heat source (4) located on the device (2) and enabling the raw material (H) from the feeder (3) to be melted, at least one table (5) enabling the raw material (H) to be processed thereon, at least one part (P) formed by melting and processing the raw material (H) on the table (5) by means of the heat source (4), at least one forging element (6) providing improvement in the micro- and/or macrostructure of the part (P) by exerting force on the part (P) under the control of a user and/or automatically, a base (Z) on which the device (2) is located, at least one control unit (7) enabling the position of the table (5) to be changed with respect to the base (Z).

[0050] In the manufacturing system (1) according to the invention, the forging element (6) is located opposite the device (2) on the base (Z), at least one forging surface (8) is located on the forging element (6), enabling the part (P) to be forged, at least one sliding mechanism (9) is located on the base (Z), enabling at least one of the device (5) and/or the forging element (6) to move close to the other one, and the control unit (7) enables the table (5) to stay opposite the forging surface (8) by being rotated around the point at which it is connected to the device (2) and the forging element (6) to be moved by means of the sliding mechanism (9) so that the forging surface (8) exerts force on the part (P).

[0051] The device for implementing a metal additive manufacturing method contains raw material (H) for the manufacture of parts (P) by means of the metal additive manufacturing method. The feeder (3) enables the raw material (H) to be deposited on the table (5). The heat source enables the raw material (H) to be melted and processed on the table. Grain size and/or porosity problems possibly occurring on the part (P) are improved in the micro- and/or macro dimension of the part (P) by the forging element (6) applying force on the part (P).

[0052] The forging element (6) is located on the same base (Z) and the same sliding mechanism (9) as the device (2) so as to face the device (2). The forging surface (8) is located on the forging element (6) so as to stay opposite the table (5), enabling the part (P) to be forged. The control unit (7) enables the table (5) to be rotated around the point at which it is connected to the device so as to stay opposite the forging surface (8) and the forging element (6) to be slid towards the device (2) by means of the sliding mechanism (9) so that the forging surface (8) exerts a force on the part (P). (FIG.-1)

[0053] In an embodiment of the invention, the manufacturing system (1) comprises at least one support element (10) extending from the base (Z) towards the table (5), a connection point (11) at which the table is connected to the support element (10), at least one support leg (12) located on the forging element (6) and extending from the base (Z) to the forging surface (8), a pivot point (13) at which the forging surface (8) is connected to the support leg (12), wherein the control unit (7) enables the position of the forging surface (8) around the pivot point (13) and of the table (5) around the connection point (11) to be changed with respect to the base (Z) and thus ensures that the table (5) and the forging surface (8) stay almost completely opposite to each other. The table (5), the support element (10) and the connection point (11) make up the device (2). The forging surface (8), the support leg (12) and the pivot point (13) form the forging element (6).

[0054] In an embodiment of the invention, the control unit (7) enables the table (5) to be rotated around the connection point (11) so as to become perpendicular to the base (Z) and get positioned opposite the forging surface (8). The control unit (7) enables the table (5) to rotate around the connection point (11) so as to become perpendicular to the base (Z), such that it stays opposite the forging surface (8) which is located perpendicular to the base (Z).

[0055] In an embodiment of the invention, the manufacturing system (1) comprises at least a first transmission element (14) located on the table (5) and enabling a force exerted on it to be transferred, at least a second transmission element (15) located on the forging surface (10) and enabling a force exerted on it to be transferred, wherein when at least one of the table (5) and/or the forging surface (10) comes close to the other one by means of the sliding mechanism (12) and the part (P) stays between the table (5) and the forging surface (10), the control unit (7) enables the first transmission element (14) and the second transmission element (15) to be energized so that the force exerted on the part (P) is distributed evenly throughout the part (P). The fact that there is a spring on both the table (5) and the forging surface (8) provides the generation of a double-acting force on the part (P), thereby enabling the microstructure of the part (P) during its manufacture to be improved.

[0056] In an embodiment of the invention, the manufacturing system (1) comprises at least one table substrate (16) between the table (5) and the support element (10), enabling the first transmission element (14) to stay between the table (5) and itself, at least one first actuator (17) located in connection with the table substrate (16) and enabling the first transmission element (14) to exert force to the table (5) by being energized by the control unit (9), at least one forging substrate (18) between the forging surface (8) and the support leg (12), enabling the second transmission element (15) to stay between the forging surface (10) and itself, and at least one second actuator (19) located in connection with the forging substrate (18) and enabling the second transmission element (15) to exert force to the forging surface (10) by being energized by the control unit (7). The spring is compressed between the table (5) and the table substrate (16). The first transmission element (14) energized by means of the first actuator (17) on the table substrate (16), enables the force to be transferred to the part (P) on the table (5). The second transmission element (15) energized by means of the second actuator (19) on the forging substrate (18), enables the force to be transferred onto the part (P) through the forging surface (8). The spring is compressed between the forging substrate (18) and the forging surface (6).

[0057] In an embodiment of the invention, the forging surface (8) has mirror symmetry with respect to the table (5), thereby enabling the part (P) to stay between the table (5) and itself.

[0058] In an embodiment of the invention, the forging surface (8) has a larger cross-sectional area than the part (P), thereby enabling a force to be applied on almost the entirety of the part (P) at the same time. Thanks to the forging surface having a cross-sectional area larger than the cross-sectional area of the part (P), an area-based forging is applied instead of a spot-based forging.

[0059] In an embodiment of the invention, the manufacturing system (1) comprises a sensor (20) located on the forging surface (10) and transmitting to the control unit (7) that the forging surface (10) comes into contact with the part (P), thereby enabling the movement of the table (5) and the forging surface (8) on the sliding mechanism (9) to be stopped when the part (P) stays between the table (5) and the forging surface (8). Thanks to the sensor (20) located on the forging surface (8), it is determined whether the forging surface (8) is in contact with the part (P) and it is ensured that the forging element (6) is stopped to start the forging process.

[0060] In an embodiment of the invention, the manufacturing system (1) comprises a rotary element (21) located between the table substrate (18) and the support element (7), enabling the table (5) to rotate around its axis while the part (P) is manufactured on the table (5). The table (5) rotates around its axis so that the part (P) is manufactured by the metal additive manufacturing process.

[0061] In an embodiment of the invention, the control unit (9) enables the forging surface (10) to automatically exert force on the part (P) at user-determined layer number breaks. The forging process is carried out in breaks between the number of layers as predetermined by the user.

[0062] In an embodiment of the invention, the forging surface (8) is almost entirely form-fitting to the part (P) so that the part (P) is manufactured in layers such that the form of the first layer deposited on the table (5) will not change. If the first layer of the part (P) rises invariably, this means that the forging surface is manufactured in a form-fitting manner to the first layer.

[0063] In an embodiment of the invention, the part (P) is manufactured by a direct energy deposition method in the manufacturing system (1).
