In the present embodiment, the second step time includes the second execution time required for the execution of the second step by the second facility 32 and the second additional time associated with the execution of the second step by the second facility 32. The second addition time is the time required to prepare for the execution of the second step in the second facility 32 (time before the second execution), and the next step becomes possible after the execution of the second step in the second facility 32. Includes at least one of the time required until (time after the second execution). The time before the second execution includes the time required for warming up the second equipment 32 and the time for setting the object of the second step in the second equipment 32.

The process time may be a constant set for the equipment 30 or a variable. The process time may be a variable whose parameters are the shape of the three-dimensional object formed by the equipment 30 and the person (worker) who works using the equipment 30. Since the complexity of the shape of the three-dimensional object and the ability of the worker (skill level, etc.) are considered to affect the process time, even with the same equipment 30, the process time depends on the complexity of the shape of the three-dimensional object and the worker. May change. In this case, the process time can be given by a look-up table or function. These points are the same in the confirmation time and the transportation time.

For example, in the transportation time between the first equipment 31 and the second equipment 32, the delivery company transports the three-dimensional object from the place of the first equipment 31 (or its vicinity) to the place of the second equipment 32 (or its vicinity). It may be determined based on the actual time it takes to do so. Also, the transport time may be determined based on the time distance rather than the physical distance. The time distance is an index that expresses the time required for a person or an object to move between two points. For example, the transport time between the first equipment 31 and the second equipment 32 is based on the time distance between the location of the first equipment 31 (or its vicinity) and the location of the second equipment 32 (or its vicinity).

The process success probability includes the first process success probability, which is the success probability of the first process, and the second process success probability, which is the success probability of the second process. The success probability of the first process can be determined by the success probability of the execution of the first process by the first equipment 31 and the success probability of the work accompanying the execution of the first process by the first equipment 31. The work accompanying the execution of the first process by the first equipment 31 enables the next process after the preparatory work for the execution of the first process in the first equipment 31 and the execution of the first process in the first equipment 31. Includes at least one with the work to do. The success probability of the second process can be determined by the success probability of the execution of the second process by the second equipment 32 and the success probability of the work accompanying the execution of the second process by the second equipment 32. The work accompanying the execution of the second process by the second equipment 32 enables the next process after the preparatory work for the execution of the second process in the second equipment 32 and the execution of the second process in the second equipment 32. Includes at least one with the work to do. Even with the same equipment 30, the process success probability may be set for each person (worker) who works using the equipment 30. This is because the process success probability can change depending on the skill level of the worker.

The confirmation success probability is the probability of successful quality confirmation performed after at least one of one or more first steps and one or more second steps. The confirmation success probability is statistically obtained from the past success / failure history of quality confirmation. The confirmation success probability includes a first quality confirmation success probability, which is the success probability of the first quality confirmation process, and a second quality confirmation success probability, which is the success probability of the second quality confirmation process.

In the present embodiment, the delivery date refers to information that directly or indirectly indicates the time when the three-dimensional object arrives at the destination specified by the client. For example, the delivery date may be the date and time when the three-dimensional object arrives at the delivery destination specified by the client, or the time required for the three-dimensional object to arrive at the delivery destination specified by the client. The starting point of the delivery date is assumed to be the start time of the calculation of the delivery date, but the starting point of the delivery date may be any time point. This makes it possible to calculate the delivery date, etc. when requesting the production of a three-dimensional object one week after the present time. The delivery date information D20 further includes a success probability of manufacturing a three-dimensional object manufactured according to the manufacturing process information D11. Since the delivery date information D20 is generated by the arithmetic circuit 14, the calculation of the delivery date and the success probability in the delivery date information D20 will be described later.

The arithmetic circuit 14 is a circuit that controls the operation of the manufacturing execution system 10. The arithmetic circuit 14 is connected to the input / output device 11 and the communication device 12, and can access the storage device 13.

The manufacturing execution system 10 can acquire the three-dimensional object information D10 input to the delivery date presentation system 50 from the delivery date presentation system 50.

The determination process is a process of determining the manufacturing process of the three-dimensional object based on the three-dimensional object information D10 and generating the manufacturing process information D11. In the determination process, a plurality of steps (one or more first steps and one or more second steps) required for manufacturing a three-dimensional object are specified based on the three-dimensional object information D10, and the order of the plurality of steps is determined. In the determination process, a manufacturing process is determined by adding a quality confirmation process and a transportation process as necessary to a plurality of ordered processes. For example, it is assumed that the production of a three-dimensional object requires a step of forming a modeled object from a resin material with a 3D printer and a step of surface-treating the modeled object with a surface treatment device. In this example, the former process is specified as the first process A, and the latter process is specified as the second process B. Since the execution of the second step B requires the completion of the first step A, the order of the first step A and the second step B is such that the first step A comes first and the second step B comes later. Then, a quality confirmation step and a transportation step are attached to each of the first step A and the second step B, and as shown in the first example of FIG. 5, the first step A (S11) and the quality confirmation step (S12) are attached. ), The transport step (S13), the second step B (S14), the quality confirmation step (S15), and the transport step (S14) are executed in this order.

For example, the three-dimensional object may be disassembled into a plurality of parts, and a part for assembling (concavo-convex part or the like) may be added to each part. For example, the shape of the three-dimensional object may be a shape obtained by removing an unnecessary portion from the three-dimensional object or a shape in which a necessary portion is added. The unnecessary portion or the necessary portion may be determined based on the shape information, the attribute information, the priority information, and the like included in the three-dimensional object information D10. When the shape information included in the three-dimensional object information D10 is information that indirectly specifies the shape of the three-dimensional object, the determination process may include a process of creating data expressing the shape of the three-dimensional object from the shape information. ..

The selection process is a process of selecting the equipment 30 used for manufacturing a three-dimensional object. In the present embodiment, the selection process extracts one or more first equipment 31 and one or more second equipment 32 from the list of equipment 30 available in the manufacturing system 1 of equipment information D12. More specifically, the selection process can search a list of equipment using the additive manufacturing technology (first list of equipment information D12) based on the manufacturing process information D11 and execute one or more first steps. 1 or more first equipment 31 is extracted. With respect to the first example of FIG. 5, the selection process extracts one or more first facilities 31 capable of performing the first step A. In the selection process, one or more second steps can be executed by searching a list of equipment using manufacturing technology other than the additive manufacturing technology (second list of equipment information D12) based on the manufacturing process information D11. Extract one or more second equipment 32. With respect to the first example of FIG. 5, the selection process extracts one or more second facilities 32 capable of performing the second step B. For example, as shown in FIG. 6, in the selection process, four first facilities 31A to 31D capable of executing the first step A are extracted, and three second facilities 32A to 32C capable of executing the second step B are extracted. Extract.

In the selection process, referring to the manufacturing process information D11, one or more specific first equipment 31 used for one or more first equipment 31 is selected from one or more first equipment 31, and one or more second equipment 32. Select one or more specific second equipment 32 to be used for one or more second steps. Regarding the first example of FIG. 5, in the selection process, one specific first equipment 31 used for the first step A is selected from the four first equipments 31A to 31D, and the three second equipments 32A to 32C are selected. Select one specific second equipment 32 to be used in the second step B from. In this case, since there are 12 combinations of the specific first equipment 31 and the specific second equipment 32, it is possible to obtain the delivery date for the 12 combinations.

In the selection process, first and second conditions are provided for the selection of the specific first equipment 31. The first and second conditions are conditions relating to the available time of the first equipment 31. The usage schedule information D13 is used to determine whether the first equipment 31 satisfies the first and second conditions. The first condition of the specific first equipment 31 is that each specific first equipment is the first equipment 31 that becomes available within a predetermined time (first predetermined time) among one or more first equipments 31. ,. The first predetermined time may be determined based on the permissible limit at the scheduled start time of the first step. For example, in the example of FIG. 6, when one cell is 6 hours and the first predetermined time is 24 hours, the first equipments 31B to 31C have time available within 24 hours, but the first equipment 31A The first equipment 31A is not selected as the particular first equipment 31 because there is no time available within 24 hours. The second condition of the specific first equipment 31 is that the specific first equipment 31 uses one or more first equipments 31 in which the available time from the scheduled start time of the first process includes the first process time. It is the first equipment 31 that is more than an hour. This is because even if the first equipment 31 is available, it is not suitable as the specific first equipment 31 unless the first step can be completed. The usage time may be equal to the first process time, but may be longer than the first process time in order to have a certain margin. For example, in the example of FIG. 6, when the usage time is 18 hours, the first equipment 31B can be used for 18 hours from the scheduled start time of the first process after 12 hours. Is selected as the specific first facility 31. The first equipment 31C is not selected as the specific first equipment 31 because 6 hours later is the scheduled start time of the first step and is not available for 18 hours from the scheduled start time of the first step. Since the first equipment 31D is available for 18 hours from the scheduled start time of the first process after 0 hours, it can be selected as the specific first equipment 31.

In the selection process, first and second conditions are provided for the selection of the specific second equipment 32. The first and second conditions are conditions relating to the available time of the second equipment 32. The usage schedule information D13 is used to determine whether the second equipment 32 satisfies the first and second conditions. The first condition of the specific second equipment 32 is that each specific second equipment is the second equipment 32 that becomes available within a predetermined time (second predetermined time) among the one or more second equipment 32. ,. The second predetermined time may be determined based on the allowable limit at the scheduled start time of the second step. For example, in the example of FIG. 6, when one cell is 6 hours and the second predetermined time is 72 hours, the second equipments 32A and 32B have time available within 72 hours, but the second equipment 32C The second equipment 32C is not selected as the particular second equipment 32 because there is no time available within 72 hours. The second condition of the specific second equipment 32 is that each specific second equipment is at least one of one or more specific first equipments 32 from the scheduled start time of the first step. The second equipment 32 has an available time after the lapse of the standby time including the first process time, which is equal to or longer than the second process time. This is because when the second step is executed after the first step, the specific second facility 32 can start the second step only after the completion of the first step in the specific first facility 31. This is because the second step cannot be completed if the available time is shorter than the second step time at that time. The waiting time may be equal to the time of the first step, but as described above, the quality confirmation step and the transportation step may be included between the first step and the second step. The time may be longer than the first process time in consideration of the confirmation time and the transportation time. For example, in the first example of FIG. 5, the second step B is executed after the first step A. In this case, it is assumed that the standby time is 24 hours and the second process time is 12 hours. When the first equipment 31B is a specific first equipment, the waiting time elapses after 36 hours because the scheduled start time of the first process is 12 hours later, and the second equipments 32A and 32B Has an available time of the second process time (12 hours) or more. Therefore, when the first equipment 31B is a specific first equipment, both the second equipments 32A and 32B can be selected as the specific second equipment. When the first equipment 31D is a specific first equipment, the waiting time elapses after 24 hours because the scheduled start time of the first process is 0 hours later, and the second equipments 32A and 32B have There is an available time of the second process time (12 hours) or more. Therefore, when the first equipment 31B is a specific first equipment, both the second equipments 32A and 32B can be selected as the specific second equipment.

The generation process is a process for generating the delivery date information D20. The delivery date information D20 includes the delivery date and the success probability as described above.

One or more specific first equipment 31 and one or more specific second equipment 32 used for one or more second steps can be specified. The first process time (if necessary, the first confirmation time) can be obtained from the required time information D14 for the combination of the first process and the specific first equipment 31. The second process time (if necessary, the second confirmation time) can be obtained from the required time information D14 for the combination of the second process and the specific second equipment 32. The transportation time can be obtained from the required time information D14 for the combination of one or more specific first equipment 31 and one or more specific second equipment 32. Then, the order of 1 or more 1st process, 1 or more 2nd process, and other processes (quality confirmation process and transportation process) can be understood from the manufacturing process, and 1 or more 1st process and 1 or more from the usage schedule information D13. The waiting time for executing the second step (time until one or more specific first equipment 31 and one or more specific second equipment 32 become available) can be specified. The estimated time can be obtained by comprehensively considering these. 7, FIG. 9, FIG. 11, FIG. 13, and FIG. 15 are explanatory views of an example of calculation of the delivery date of each of the first to fifth examples of the manufacturing process. An example of calculating the delivery date will be described in detail in "(1-3) Example of manufacturing process" described later.

As described above, the correspondence information D16 is information indicating the correspondence relationship between the estimated time required for the delivery date and the actual working time until the delivery date actually taken for the three-dimensional object. It is considered that a similar correspondence is established for three-dimensional objects having similar characteristics (for example, characteristics related to shape, size, material, etc.). Three-dimensional objects can be classified into a plurality of categories according to such characteristics. Then, a trained model in which the input / output relationship between the estimated time and the actual working time is learned can be prepared for each category of the three-dimensional object. For such a trained model, for example, machine learning of a model (for example, an estimation program having a neural network structure) is performed using training data (training data set) in which an estimated time is input and the actual working time is the correct answer. Obtained by running. The correction process obtains the corrected estimated time corresponding to the actual working time by inputting the estimated time obtained by the estimation process into the trained model of the category corresponding to the three-dimensional object.

In the generation process, the delivery date of the three-dimensional object is determined with reference to the estimated time (in the present embodiment, the estimated time after correction). If the delivery date is the time it takes for the three-dimensional object to reach the destination specified by the client, the estimated time after correction is adopted as the delivery date. If the delivery date is the date and time when the three-dimensional object arrives at the destination specified by the client, the date and time after the estimated time after correction has elapsed is adopted as the delivery date.

The generation process is manufactured according to the manufacturing process information D11 using one or more specific first equipment 31 and one or more specific second equipment 32 selected in the selection process with reference to the success probability information D17. Calculate the success rate of manufacturing a three-dimensional object. From the manufacturing process information D11, one or more first processes, one or more second processes, and other processes (quality confirmation process and transportation process) included in the manufacturing process can be specified, and are used for one or more first processes by selection processing. One or more specific first equipment 31 and one or more specific second equipment 32 used for one or more second steps can be specified. For the combination of the first step and the specific first equipment 31, the success probability of the first step (if necessary, the success probability of the first confirmation) can be obtained from the success probability information D17. For the combination of the second step and the specific second equipment 32, the second step success probability (if necessary, the second confirmation success probability) can be obtained from the required time information D14. For the combination of one or more specific first equipment 31 and one or more specific second equipment 32, the transportation success probability can be obtained from the success probability information D17. Then, since the order of one or more first steps, one or more second steps, and other steps (quality confirmation step and transportation step) is known from the manufacturing process, the success probability can be obtained. For example, in the case of the first example of FIG. 5, the success probability of the first step of the first step A (S11), the success probability of the first probability of the quality confirmation step (S12), the success probability of transport of the transport step (S13), and the second The product of the second step success probability of the step B (S14), the second confirmation success probability of the quality confirmation step (S15), and the transportation success probability of the transportation step (S14) is the success probability.

In the present embodiment, when the client approves the production of the three-dimensional object in response to the presentation of the delivery date information D20, the execution process is started.

The correction process is a process of correcting the required time information D14 based on the time difference information D15. The time difference information D15 is information regarding a time difference between a specific required time among a plurality of required times and an actual time corresponding to the specific required time. The correction process modifies the specific required time so that the time difference becomes small with respect to the specific required time. As a result, the accuracy of the specific required time can be expected to be improved, and as a result, the accuracy of the calculation of the delivery date can be expected to be improved. For example, when the actual time for executing the first process of the first equipment 31 is obtained, the time difference information D15 is information regarding the time difference between the first process time and the actual time for the first process of the first equipment 31. Will have. In this case, the correction process corrects the first process time so that the time difference with respect to the first process of the first equipment 31 becomes small. By obtaining the information regarding the actual time in this way, the time difference information D15 is updated, the correction process is executed accordingly, and the required time information D14 is updated.

The collection process is a process of collecting information from an external device or system (for example, the management system 40 and the delivery date presentation system 50) through the interface (input / output device 11 and communication device 12) and storing the information in the storage device 13. The information from the external device or system includes, for example, feedback information related to the manufacturing process performed by the manufacturing system 1. Examples of feedback information include information on the actual working time until the actual delivery date and information on the actual time corresponding to the required time. The actual working time information can be obtained from the delivery date presentation system 50 and is used for updating the correspondence information D16. By updating the correspondence information D16, it becomes possible to relearn the trained model used in the correction processing, and it is expected that the accuracy of the correction of the correction time by the correction processing will be improved, and thereby the accuracy of the calculation of the delivery date can be expected to be improved. .. The actual time information corresponding to the required time can be obtained from the management system 40 and is used for updating the time difference information D15.

In the manufacturing system 1, the delivery date presentation system 50 is assumed to be used by a client who requests the manufacturing of a three-dimensional object. In the manufacturing system 1, the delivery date presentation system 50 is used for inputting information from the requester for manufacturing a three-dimensional object to the manufacturing execution system 10 and outputting information from the manufacturing execution system 10 to the client. As shown in FIG. 4, the delivery date presentation system 50 includes an interface (input / output device 51 and communication device 52), a storage device 53, and an arithmetic circuit 54. In the present embodiment, the delivery date presentation system 50 is realized by one terminal device.

FIG. 4 shows a state in which the storage device 53 stores the three-dimensional object information D10 and the delivery date information D20. The three-dimensional object information D10 does not have to be stored in the storage device 53 at all times, and may be stored in the storage device 53 when required by the arithmetic circuit 54. The delivery date information D20 is stored in the storage device 53 after being received from the manufacturing execution system 10 through the communication network 62.

The calculation circuit 54 is a circuit that controls the operation of the delivery date presentation system 50. The arithmetic circuit 54 is connected to the input / output device 51 and the communication device 52, and can access the storage device 53. The arithmetic circuit 54 can be realized, for example, by a computer system including one or more processors (microprocessors) and one or more memories. The function as the arithmetic circuit 54 is realized by executing the program (stored in one or more memories or the storage device 53) by one or more processors. Although the program is pre-recorded in the storage device 53 here, it may be recorded and provided through a telecommunication line such as the Internet or a non-temporary recording medium such as a memory card.

The arithmetic circuit 54 is configured to execute acquisition processing, transmission processing, reception processing, and output processing.

The acquisition process is a process of acquiring the three-dimensional object information D10 by the input / output device 51. In the acquisition process, for example, the input / output device 51 presents a screen for inputting the three-dimensional object information D10, and the requester can input the three-dimensional object information D10 according to the instructions on the screen. The input of the three-dimensional object information D10 is not only to input the three-dimensional object information D10 to the delivery date presentation system 50 from an external device, but also to specify the data to be used as the three-dimensional object information D10 from the data stored in the delivery date presentation system 50. May also be included.

Through the acquisition process and the transmission process, the client can input the three-dimensional object information D10 into the manufacturing execution system 10 through the delivery date presentation system 50.

The reception process is a process of receiving the delivery date information D20 generated by the manufacturing execution system 10 from the manufacturing execution system 10 through the communication device 52. The output process is a process of presenting the delivery date information D20 received in the reception process by the input / output device 51. In the output process, for example, the input / output device 51 presents a screen for outputting the delivery date information D20, and the requester can grasp the delivery date and the success probability indicated by the delivery date information D20 by looking at the screen. Through the reception process and the output process, the client can confirm the delivery date information D20 corresponding to the three-dimensional object information D10 through the delivery date presentation system 50.

The arithmetic circuit 54 causes the input / output device 51 to display a screen asking whether or not the client approves the production of the three-dimensional object in response to the presentation of the delivery date information D20, and when the client's approval is obtained, the input / output device 51 displays the screen. , The manufacturing execution system 10 is notified through the communication network 62 that the client has approved the manufacturing of the three-dimensional object. The arithmetic circuit 54 acquires information on the delivery date result of the three-dimensional object through the input / output device 51, and transmits the information from the communication device 52 to the manufacturing execution system 10 through the communication network 62 as needed. Information on the result of the delivery date of the three-dimensional object includes information on the date and time when the three-dimensional object actually arrived at the destination specified by the client (that is, the actual working time until the actual delivery date).

In this way, the client can provide the three-dimensional object information D10 to the manufacturing execution system 10 through the delivery date presentation system 50, confirms the delivery date information D20 from the manufacturing execution system 10, and actually manufactures the three-dimensional object. You can make a request.

FIG. 15 is an explanatory diagram of the delivery date in the fifth example, and shows an arrow diagram for calculating the delivery date. Node "1" is the time when the request for manufacturing the three-dimensional object is made, and node "11" is the time when the three-dimensional object arrives at the destination specified by the requester. W51 and W52 indicate the waiting time for the first equipment 31t and 31u, respectively, and tw51 and tw52 indicate the waiting time for the first equipment 31t and 31u, respectively. W53 to W55 indicate the waiting time for the second equipment 32v to 32x, respectively, and tw53 to tw55 indicate the waiting time for the second equipment 32v to 32x, respectively. t51 and t52 indicate the required time of the steps S51 and S52 (the process time of the first steps T and U, the confirmation time of the quality confirmation step, and the total of the transportation steps), respectively. t52 to t55 indicate the required time of the steps S52 to S55 (the process time of the second steps V to X, the confirmation time of the quality confirmation step, and the total of the transportation steps), respectively.

The estimated delivery time is represented by the critical path in the arrow diagram of FIG. For example, tw51 = 11 hours, tw52 = 21 hours, tw53 = 37 hours, tw54 = 17 hours, tw55 = 23 hours. T51 = 22 hours, t52 = 12 hours, t53 = 11 hours, t54 = 32 hours, t55 = 26 hours. In this case, tw53 (= 37 hours)> tw51 + t51 (= 11 + 22 = 33), and the time from the nodes "1" to "5" is 37 + t53 (= 11) = 48 hours. tw54 (= 17 hours) <tw52 + t52 (= 21 + 12 = 33), and the time from the nodes “1” to “9” is 33 + t54 (= 32) = 68 hours. Since tw55 is 26 hours, the estimated time is the time from nodes "1" to "9" (= 68) + t55 (= 26) = 94 hours.
It will be 197 hours.

(1-3-6) 6th Example In the 1st to 5th examples, it is assumed that one three-dimensional object is manufactured. The manufacturing system 1 may manufacture a plurality of the same three-dimensional objects based on the three-dimensional object information D10. In this case, by using a plurality of first equipment 31s in parallel, a plurality of three-dimensional objects can be modeled in parallel, and a plurality of three-dimensional objects can be modeled in series by a single first facility 31. Compared to the case of doing so, the delivery time can be shortened.

The sixth example of the manufacturing process is an example of manufacturing a plurality (two) of the same three-dimensional object. A manufacturing process similar to that of the fourth example of the manufacturing process shown in FIG. 12 can be applied to the sixth example. That is, in the sixth example, steps S41 and S42 including the first steps L and M and steps S43, S44, S45, S46, S47 and S48 including the second steps N, O, P, Q, R and S, respectively. including.

Steps S41, S43, S45, S47 and steps S42, S44, S46, S48 are independent of each other and can be executed in parallel.

In the sixth example, the first steps L and M are steps of forming a modeled object corresponding to a three-dimensional object from a metal material with the first equipments 31l and 31m, respectively. The second steps N and O are steps of sintering the modeled objects obtained in the first steps L and M in the second equipment 32n and 32m, respectively. The second steps P and Q are steps in which the modeled objects obtained in the second steps N and O are machined by the second equipment 32p and 32q to cut out the necessary surfaces. The second steps R and S are steps of sintering the modeled objects obtained in the second steps P and Q by the second equipment 32r and 32s, respectively. In the sixth example, one three-dimensional object is manufactured by a series of steps S41, S43, S45, and S47, and one three-dimensional object is manufactured by a series of steps S42, S44, S46, and S48. As a result, a total of two three-dimensional objects are manufactured.

Each of the steps S41 to S48 includes a quality confirmation step and a transportation step. The quality confirmation step is a step for confirming the quality of the result of the first step or the second step immediately before. The transportation steps of steps S41 to S46 are steps for transporting to a place where the next step is executed. The transportation steps of steps S47 and S48 are steps for transporting to the delivery destination designated by the client.

In the sixth example, the arrow diagram of FIG. 13 can be applied as in the fourth example. The estimated delivery time is as described in the fourth example, the time required for the series of steps S41, S43, S45, S47 is 158 hours, and the time required for the series of steps S42, S44, S46, S48 is It will be 197 hours. When two three-dimensional objects are delivered separately, the first three-dimensional object can be delivered in 158 hours, and the second three-dimensional object can be delivered in 197 hours. On the other hand, when two three-dimensional objects are delivered together, they are delivered according to the latest estimated time, but the delivery time is longer than when a plurality of three-dimensional objects are manufactured by a single first facility 31. Expected to be shortened. The sixth example is an example of producing two identical three-dimensional objects, but it can also be applied to an example of producing three or more identical three-dimensional objects. That is, in the case of manufacturing a plurality of the same three-dimensional objects, the delivery time can be shortened by modeling the same three-dimensional objects in parallel by the plurality of first equipments 31. In this case, at least one of the plurality of first facilities 31 may form two or more identical three-dimensional objects, if necessary. Ideally, each of the plurality of first equipments 31 should form one three-dimensional object, but it may not be possible to use a sufficient number of the first equipments 31 in parallel depending on the schedule or the like. In the sixth example, the second step is individually added to the first steps S41 and 42, but if the second step can work in parallel with a plurality of shaped objects, the first step S41, It is also possible to utilize the common second step after 42.
