Description

Integrated lamination manufacturing method and manufactured object

Technical Field

The present invention relates to a method of additive manufacturing, and more particularly, to an integrated additive manufacturing method for reducing a required manufacturing space and an article manufactured thereby.

Background

In recent years, the technology of Additive Manufacturing has been greatly advanced. Due to the improvement of the production speed, the lamination manufacturing technology can be used for batch production, and the lamination manufacturing has fewer limitations compared with the traditional manufacturing, so that the product performance can be improved through the lamination manufacturing in the product design. However, the current additive manufacturing technology must be manufactured in a cavity with a limited volume, and if the size of the part or component is larger than the size of the cavity, the part or component must be divided to reduce the size of the part or component. After the respective fabrication is completed, the components are then combined or assembled in a post-processing manner. Moreover, when a large-sized part or component is manufactured in a one-off process in a larger-sized forming cavity, a longer production time is required, which results in a reduced productivity.

On the other hand, the additive manufacturing technology such as Powder melt molding (PBF) has a characteristic of no support, and can realize additive manufacturing of various fine components. But still limited by the minimum distance limit of the powder melting and molding technology, when a plurality of components are produced in batch, the distance between the components must be larger than the minimum distance limit of the powder melting and molding technology, so that a necessary clearance space is maintained between the components, heat can be dissipated in the production process, and meanwhile, the components are prevented from being adhered to form defective products in the cooling process. Therefore, in a limited manufacturing space, there are still many limitations in applying the conventional additive manufacturing to the batch production of each component, and the production efficiency cannot be effectively improved.

In view of the above, how to develop an integrated build-up manufacturing method for reducing the required manufacturing space to solve the problems in the prior art is an urgent issue to be solved in the field.

Detailed Description

Exemplary embodiments that embody features and advantages of the invention are described in detail in the description that follows. As will be realized, the invention is capable of modifications in various obvious respects, all without departing from the scope of the invention, and the description and drawings are to be regarded as illustrative in nature, and not as restrictive.

FIG. 1 is a flow chart of an integrated build-up manufacturing method for reducing the required manufacturing space according to a preferred embodiment of the present invention. FIG. 2 is a schematic diagram of an object manufactured in a manufacturing space for build-up manufacturing according to a first preferred embodiment of the present invention. FIG. 3 is a schematic view of an object in a space using process according to a first preferred embodiment of the present invention. In the present embodiment, first, in step S01, an object 1 is manufactured by lamination, wherein the object 1 includes at least one first element 10, at least one second element 20, and at least one rotation axis C, the first element 10 and the second element 20 are pivotally connected to each other through the rotation axis C, and the first element 10 is adjacent to the second element 20. So that the object 1 can be laminated in a manufacturing space S. In the present embodiment, the first assembly 10 includes at least one first engaging element 11, the second assembly 20 includes at least one second engaging element 21, the first engaging element 11 and the second engaging element 21 are spatially opposite to each other, and the first engaging element 11 and the second engaging element 21 are separated from contact with each other when the object 1 is subjected to the additive manufacturing in the manufacturing space S. In the present embodiment, the lamination manufacturing of step S01 can utilize, for example, a Powder melt molding (PBF) technique to obtain the object 1. In the embodiment, the rotation axis C may be respectively disposed on the first component 10 and the second component 20 through a combination of the shaft body and the pivot hole, for example, and the invention is not limited to the pivot method and is not repeated herein. It should be noted that a minimum spacing (not labeled) exists between the first component 10 and the second component 20a to maintain a required gap during the lamination process, so as to ensure that no adhesion occurs between the first component 10 and the second component 20a and the rotation axis C due to heat dissipation during the cooling process. In the present embodiment, the minimum spacing distance ranges from 0.3mm to 0.5mm, so as to meet the requirement of additive manufacturing. After the additive manufacturing production is completed, in step S02, the object 1 is moved out of the manufacturing space S, the first assembly 10 is rotated by an adjustment angle θ relative to the second assembly 20 about the rotation axis C, and the first engaging member 11 and the second engaging member 21 are engaged and locked with each other, so that the object 1 forms a usage space (see fig. 3), wherein the usage space is larger than the manufacturing space S.

It should be noted that, according to the present invention, by using the aforementioned integrated lamination manufacturing method such as Powder Fusion molding (PBF), the large-sized object 1 is designed to be foldable for production, so that the manufacturing space S required for lamination manufacturing can be reduced, and the production density can be increased. The object 1 is produced by at least one rotating shaft C and the irreversible engaging member structure formed by combining the first engaging member 11 and the second engaging member 21, so that the object 1 can be changed between a production position (see fig. 2) and a use position (see fig. 3) of the lamination manufacturing, the object 1 is kept in a folded state at the production position, the manufacturing space S smaller than the actual use space of the object 1 is used for production, meanwhile, the gap requirement among the rotating shaft C, the first assembly 10 and the second assembly 20 is maintained, and adhesion caused by heat which cannot be dissipated in the cooling process is avoided. On the other hand, the first element 10 and the second element 20 of the object 1 are unfolded after production by at least one rotation axis C, and the first engaging element 11 and the second engaging element 21 are used to fix the positions of the first element 10 and the second element 20. Therefore, the integrated lamination manufacturing method can achieve the purpose of reducing the required manufacturing space S, simplify the manufacturing process of the large-size object 1, save the manufacturing cost and improve the operation efficiency.

In this embodiment, the usage space of the object 1 is larger than the manufacturing space S defined in the integrated build-up manufacturing. The manufacturing space S has, for example, a maximum diameter value D, the first component 10 has a first maximum length value L1, and the second component 20 has a second maximum length value L2, wherein the maximum diameter value D is greater than the first maximum length value L1 and the second maximum length value L2, respectively, so as to facilitate the object 1 to be accommodated in the manufacturing space S for the additive manufacturing process. After the production is completed, the object 1 is moved out of the manufacturing space S, the first assembly 10 is rotated by an adjustment angle θ relative to the second assembly 20 about the rotation axis C, and the first engaging member 11 and the second engaging member 21 are engaged and locked with each other, so that the object 1 forms a use space (see fig. 3). For the conventional additive manufacturing method, the used space of the object 1 is the originally required manufacturing space. However, the integrated build-up manufacturing method of the present invention can reduce the originally required manufacturing space (usage space) to meet the limitation of the manufacturing space S. See fig. 2 and 3. In the present embodiment, the adjustment angle θ for the rotation of the first assembly 10 relative to the second assembly 20 may be, for example, between 90 degrees and 270 degrees. If the space in which the object 1 is expanded is represented by a maximum feature length value P, the maximum feature length value P can be expressed as the following formula (1):

P²＝L1²+L2²-2×L1×L2×cosθ (1)

the first component 10 and the second component 20 of the object 1 can be contracted through the rotating shaft C during the lamination manufacturing process and are contained in the manufacturing space S with the maximum diameter value D, so that the purpose of reducing the required manufacturing space is achieved. In other words, the object 1 with the maximum characteristic length value P after being unfolded can be manufactured in a laminated manner in the limited manufacturing space S. When the adjustment angle θ is 180 degrees, and the maximum diameter value D of the manufacturing space S is smaller than the sum of the first maximum length value L1 of the first component 10 and the second maximum length value L2 of the second component 20. The object 1 forming the use space cannot be accommodated in the manufacturing space S for the build-up manufacturing, but the object 1 can be build-up manufactured in the manufacturing space S by folding the first member 10 and the second member 20 of the object 1 about the rotation axis C as shown in fig. 2. In addition, when the adjustment angle θ is 90, and the square of the maximum diameter value D of the manufacturing space S is smaller than the sum of the square of the first maximum length value L1 of the first component 10 and the square of the second maximum length value L2 of the second component 20. The object 1 expanded to the use space cannot be accommodated in the manufacturing space S for the additive manufacturing, but the object 1 can be additive manufactured in the manufacturing space S by folding the first and

second components

10 and 20 of the object 1 through the rotation axis C, as shown in fig. 2. In other words, by designing the large-sized object 1 to be foldable for production, it is possible to reduce the manufacturing space required for the build-up manufacturing and increase the production density. The large-sized object 1 subjected to the integrated lamination manufacturing is kept in a folded state at the initial position of the manufacturing (see fig. 2) to meet the process limitation requirements, maintain the clearance limitation among the components and achieve the purpose of reducing the manufacturing space. After production, the components are rotated and unfolded through at least one rotating shaft C, and the first meshing part 11 and the second meshing part 21 are maintained to be in the maximum size, so that the components can be used without assembly. Effectively simplifying the assembly process, saving the manufacturing cost and improving the operation efficiency. It should be noted that the angle θ of the first component 10 relative to the second component 20 is adjusted to assemble the folded article 1 to meet the process limitation requirement, and can be adjusted according to the practical application requirement, and the invention is not limited thereto.
