Description

Description Title of Invention: INFORMATION PROCESSING DEVICE, MODELING DEVICE, MODELING SYSTEM, METHOD AND COMPUTER-READABLE RECORDING MEDIUM Technical Field The present ion relates to an information processing device, a ng device, a modeling system, a method and a computer—readable recording medium. ound Art The advent of modeling devices (referred to as AM ive Manufacturing) devices or 3D printers) has enabled low—cost and quick—turnaround-time manufacturing of samples and parts in a small lot. When modeling is performed with a modeling device, in general, data of a three—dimensional stereoscopic model is loaded into a CAM (Computer Aided Manufacturing) in advance and data for modeling ing data) understandable by the modeling device is generated. For example, modeling is performed by fused decomposition modeling (FDM), data of a three—dimensional stereoscopic model sliced into layers is generated and, from the data, modeling data representing a modeling ure (a g procedure) per layer is generated. The ng procedure per layer contains instruction information, represented by G codes, cting the modeling device about, for example, in which route a modeling head is to be moved, which amount of a ng material (such as resin) is to be pushed out from a nozzle of the modeling head, and at which Celsius degree the modeling material is pushed out.
For stereoscopic modeling in which layers of a dimensional object are deposited one by one, there is a disclosed method for improvement on variation in thickness of a material and size precision (see, for example, Patent Document 1).
Summary of Invention Technical Problem Modeling materials have different characteristics in, for example, the fusion tem— peratures and viscosity, depending on the types of the materials. When a modeling apparatus models the same three—dimensional stereoscopic model by changing only the modeling material, it is necessary to change the instruction ation (mainly, parameter values) according to the characteristics of the modeling material after the change. In other words, with respect to a single three—dimensional stereoscopic model, to model three—dimensional stereoscopic models for which the modeling material is changed, it is necessary to newly generate sets of modeling data corresponding to the number of times the modeling material is changed. Generating modeling data requires time and user's work and thus there is a problem in that generating modeling data cor— ding to the modeling materials increases the workload.
In view of the described circumstances, there is a need to provide an in— formation processing device, a modeling device, a modeling system, a method and a computer—readable ing medium enabling generation of modeling data that matches another modeling al from a single set of modeling data.
Solution to Problem According to ary embodiments of the present invention, there is provided an information processing device comprising: a read unit configured to read instruction information that causes a modeling device to e a modeling procedure about a first modeling material body; a storage unit configured to store modeling material body information about a second modeling material body; and a correction unit configured to correct a first parameter value about the first modeling material body, which is a first parameter value contained in the ction information read by the read unit, according to the modeling material body information stored in the storage unit.
Advantageous s of Invention An embodiment realizes an effect of enabling generation of modeling data matching another modeling material from a single set of modeling data.

Description of Embodiments The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present invention.
As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Embodiments of the information processing device, the modeling device, the modeling system, the method and the computer-readable ing medium according to the present invention will be bed in detail below with reference to the accompanying drawings. An example covering a modeling device using fused deposition modeling (FDM) will be represented below.
First Embodiment Fig. l is a diagram illustrating an exemplary system configuration of a "modeling system" according to an embodiment. A modeling system X1 illustrated as an example in Fig. l is configured to include an information processing device 1 and a modeling device 2. The information processing device 1 includes a CAM (Computer Aided Manufacturing) processing unit 1—1 and a correction processing unit 1—2 and the modeling device 2 includes a modeling processing unit 20. The "correction processing unit 1—2" corresponds to the "read unit" and the "correction unit".
The CAM processing unit 1—1 is a unit that performs CAM processing of a con— ventional method to generate data for modeling (referred to as "modeling data") that is understandable by the modeling device 2 from data of a three—dimensional model. For example, the CAM processing unit l—l slices the three—dimensional model in three— ional data from a given direction, generates instruction information enting a procedure to fill each layer obtained by the slicing with a modeling material body (a modeling ure) by combination of a command and a parameter, and tes modeling data about each layer from the bottom layer to the top layer.
The correction processing unit 1—2 is a unit that performs processing to correct the modeling data ted by the CAM processing unit 1—1 to ng data corre— sponding to a different type of modeling material body from that of the modeling al body at the time of generation of the modeling data generated by the CAM sing unit 1—1.
The modeling processing unit 20 is a unit that models a three—dimensional scopic model by using a modeling material body, which is set, ing to the modeling data corresponding to the modeling material body. For example, the modeling processing unit 20 executes a d contained in the modeling data and performs scanning with a modeling head while heating the modeling head and pushing out the modeling material body on a layer—to—layer basis from the bottom layer to the top layer. Each layer is sequentially built up and thus a three—dimensional model is modeled.

The RAM 102 is used as a work area for the CPU 100 to execute the program, etc.
The HDD 103 controls a hard disk 104 and reads and writes various types of programs and data. The HDD 103 and the hard disk 104 are an example of "the storage unit". The various types of programs include an OS (Operating System) and an ap- plication m for performing modeling data output processing. The data includes "nozzle information D1 (see Fig. 5)" that is an example of "the correspondence in- formation" and a "material profile (information) D2 (see Fig. 6)" that is an example of "the modeling al body information".

The stage 204 is provided such that the stage 204 can be elevated up and down by a Z—axis drive mechanism 216 in the Z—axis direction serving as a direction of layering. Rotation of a pulley (not illustrated) causes a filament to be pushed out from the nozzle 215 onto a build plate (not illustrated) that is arranged on the stage 204, the nt is built up in layers on the build plate, and thus a three—dimensional stereoscopic image is modeled. The stage heating unit 205 is for heating the build plate via the stage 204. The chamber heater 207 is for lling the internal ature of the chamber 203. A nozzle cleaning unit 209 is provided in the chamber 203 to clean the nozzles 215. The intra—device cooling device 208 is for cooling the inside of the device.

The "single layer minimum time" rep— resented in item k16 is a time required at minimum until the filament pushed out onto the build plate is ized (cures) on the build plate.
Functional uration Regarding the CPU 100 and the RAM 102 of the information processing device 1, the CPU 100 reads the program in the ROM 101 or the hard disk 104 to the RAM 102 and the CPU 100 executes the program between the CPU 100 and the RAM 102, thereby implementing various types of functions.
Fig. 7 is a diagram illustrating an exemplary main function of the information processing device 1 (the CPU 100 and the RAM 102). As illustrated in Fig. 7, the in— formation processing device 1 includes common functional units, such as an input receiver 10, a display output unit 11, a communication controller 12, and a storage controller 13.
The input receiver 10 receives input ation from the keyboard 105 and the mouse 106. The display output unit 11 outputs display information to the displaying display 107. The communication controller 12 establishes communication with the media drive 108, the USB I/F 110 or the network I/F 111 and its and receives data to and from a communication r. The e ller 13 reads data from a specified storage area and writes data in a ied storage area.
Furthermore, the information processing device 1 includes, as a functional unit that ms the modeling data output processing nafter, a modeling data output processor), a CAM processor 14, a modeling data reader 15, a nozzle information manager 16 (an example of "the read , a material e manager 17 (an example of "the read unit"), a layer—based correction unit 18, and an inter—layer correction unit 19 (an example of "the inter—layer correction unit"). Each of the components inputs and outputs information to and from various types of hardware, for example, via the above— described common functional units and the components cooperate with one another to perform the modeling data output processing. Each component of the modeling data output processor will be described in Fig. 11. In order to prevent descriptions of each component from being complicated in Fig. 11 and the followings, descriptions of the processing of input and output to and from the common functional units and the various types of hardware that is performed by the modeling data output processor will be omitted.
As for the CPU 250 and the RAM 252 of the modeling device 2, the CPU 250 reds the program of the ROM 251 into the RAM 252 and the CPU 250 executes the program with the RAM 252.
Fig. 8 is a diagram rating an exemplary function of the ng device 2 (the CPU 250 and the RAM 252). As illustrated in Fig. 8, the modeling device 2 im— ts a modeling unit 20a as a functional unit of the modeling processing unit 20 illustrated in Fig. 1. The modeling unit 20a reads modeling data from the network I/F 253, the USB I/F 254 or the media drive 255 and sequentially executes commands contained in the modeling data. Based on the executed commands, the modeling unit 20a controls the modeling device 2 via the input/output I/F 256.
Operations of Modeling Device WO 01111 Fig. 9 is a diagram illustrating exemplary modeling data that causes the modeling device 2 to operate. The modeling data may be in any form as long as the modeling data expresses a nozzle ature, a nozzle nt trajectory, a nozzle movement speed, an amount of the nt to be pushed out, etc. Identifying information of material types (material types of "the first ng material body") corresponding to the modeling data is contained in the header or the file name of the modeling data. The modeling data P1 illustrated in Fig. 9 is in a form of G-codes. Commands are contained in the respective rows of the modeling data P1 and the commands are processed sequentially from the top. As the definitions of the respective commands are representation of examples, they may be changed as appropriate.
"M109" represented in the first row of the modeling data Pl represents a command about the nozzle temperature. "8200" and "T0" are a parameter and its value (parameter value) and represent a temperature "200 degrees Celsius" and a nozzle number "0". In other words, "M109 8200 T0" of the first row means that the nozzle temperature of the nozzle number "0" is to be kept at 200 degrees Celsius. "T0" of the second row means that the following ds are to the nozzle whose nozzle number is "0". Accordingly, in the case of the modeling data P1 illustrated in Fig. 9, reading the first and second rows makes it le to know that the modeling data P1 indicates a modeling procedure about the nozzle whose nozzle number is "0". rmore, "G1" is a nozzle nt command. For example, "G1 X10 Y10 F600" in the fourth row means that the nozzle is to be moved at a speed of 600 mm/ min to the position (X,Y)=(10,10), where X is a parameter representing an X co— ordinate, Y is a parameter representing a Y coordinate, and F is a parameter rep— ing a speed. "G1 X20 Y10 E5 F600" in the fifth row means that the filament is to be pushed out by 5 mm while the nozzle is being moved at a speed of 600 mm/min to the on (X,Y)=(20,10), where E is a parameter representing an amount to be pushed out. Furthermore, "G1 E—1" in the sixth row means that the filament is to be drawn in by 1 mm.
Fig. 9 represents only the modeling procedure for part of one layer; however, modeling data is generated for each layer.
Figs. 10A, 10B, and 10C are tively an explanatory view of operations performed when the modeling unit 20a controls the modeling device 2 according to the modeling data P1. Figs. 10A, 10B, and 10C illustrate operations of the modeling device 2 performed when the modeling unit 20a sequentially executes the commands from the fourth row to the sixth row of the modeling data P1. Fig. 10A illustrates the state where the nozzle moves to the position (X,Y)=(10,10) according to the execution of the command of the fourth row. Fig. 10B illustrates the state where the nozzle pushes out a filament 2000 by 5 mm while moving to the position (X,Y)=(20,10) at a speed of 600 mm/min according to the execution of the command of the fifth row. Fig. 10C illustrates the state where the nozzle draws in the nt 2000 by 1 mm while being kept still in the position (X,Y)=(20,10) according to the execution of the command of the sixth row.
In this manner, the modeling unit 20a executes the commands of the modeling data P1 and controls what to be lled in the modeling device 2 on the basis of the parameter .
Operations of Information Processing Device Fig. 11 is a diagram illustrating a cooperative relationship among the onal units that s modeling data in the modeling system X1. According to Fig. 11, the function of each of the components of the ng data output processor and co— operation among the components will be described below. Note that, for various types of specifying, such as specifying a path of where data is to be saved and specifying a material type of a filament, the displaying display 107 is caused to display an operation screen to enable the user to specify a path or a material type on the operation screen by operating the keyboard 105, etc.
The CAM processor 14 reads data of a three-dimensional stereoscopic model saved in the specified path (first path) and generates modeling data of a material type, for example, specified by the user from the read data according to a conventional .
The CAM processor 14 saves the modeling data P1 that is generated according to the conventional method (see Fig. 9) in a path (second path) that is specified as where the ng data is to be saved. When there is an instruction to output the modeling data to the modeling unit 20a of the modeling device 2, the CAM processor 14 outputs the modeling data P1 to the modeling unit 20a of the modeling device 2. [005 1] The modeling data reader 15 reads the modeling data P1 that is generated by the CAM sor 14 from the second path. The modeling data reader 15 then reads the identifying information of a nozzle to be controlled (nozzle number in this example) and the identifying information of a material type (first material type) corresponding to the modeling data P1 from the read modeling data P1 and s the read sets of identifying information of the nozzle number and the first material type to the nozzle information r 16. The execution by the modeling data reader 15 is performed when the filament of the modeling device 2 is changed to a filament of another material type or where to which an output is made is changed to a modeling device in which a filament of another material type is set after the generation of the modeling data by the CAM processor 14. When the correspondence onship between the nozzle number information d10 and the material type information (111 in the nozzle in— formation Dl (see Fig. 5) does not pond to the modeling device to which an output is made, the modeling data reader 15 is implemented after the user changes the setting in the nozzle information D1 via the setting screen of the information processing device 1 or a setting for the latest correspondence relationship between the nozzle number and the material type is read from the modeling device to which an output is made and the nozzle information D1 is updated.
The nozzle number from the modeling data reader 15 is input to the nozzle information r 16 and thus the nozzle ation manager 16 reads the identifying information of the material type (the second al type) corresponding to the nozzle number from the nozzle information D1 (see Fig. 5) and outputs the fying information of the first material type and the identifying information of the second material type to the material e manager 17.
The sets of identifying information of the first and second material types from the nozzle information manager 16 are input to the material profile manager 17 and thus the material profile manager 17 reads the material profile of the first material type (the first material profile) and the material e of the second material type (the second material profile) and outputs the read material profiles to the layer—based correction unit 18 and the inter—layer correction unit 19.
The material profiles from the material profile manager 17 are input to the layer- based correction unit 18 and thus the layer—based correction unit 18 performs layer— based correction on the modeling data that is read by the modeling data reader 15 according to the material profiles. [0055 ] The inter—layer correction unit 19 further corrects the modeling correction data, which is obtained by the based correction performed by the layer—based correction unit 18, by using the material profile that is input from the material profile r 17 and inter—layer conditions (such as a difference in temperature between layers and a minimum time for modeling one layer). The inter—layer correction unit then s the modeling data after the layer correction to the modeling unit 20a of the modeling device 2.
Process Flow Fig. 12 is a diagram illustrating an exemplary order of processes of a process block of the layer—based correction process and a process block of the inter—layer correction process. As rated in Fig. 12, in the embodiment, a process block B1 of the layer— based correction process on all the layers (the first layer, the second layer, a k—th layer, a k+1—th layer, a n—th layer) is finished and then the s block B2 of the ..., inter—layer correction s is performed.
An exemplary flow of the processes of the process block B1 and the process block B2 performed by the modeling data output processor (the modeling data reader 15, the nozzle information manager 16, the material profile manager 17, the layer—based tion unit 18 and the inter-layer correction unit 19) of the information processing device 1 will be described. As the flow of generation of modeling data performed by the CAM processor 14 is a conventional process, ration in the drawings and de— scriptions of the generation flow will be omitted.
Fig. 13 is a diagram illustrating an exemplary process flow of the process block Bl of the layer-based correction process. The modeling data is not limited to that generated by the CAM processor 14. The ng data may be one generated by an external CAM device. In this case, the modeling data that is generated by the external CAM device is copied in the specified path (the second path) of the information processing device 1.
First of all, the modeling data reader 15 reads the modeling data from the second path (310). The modeling data reader 15 reads the identifying information of the nozzle to be controlled (the nozzle number in this example) and the identifying information of the material type corresponding to the modeling data P1 (the first material type) from the read modeling data (the data to be corrected) and outputs the nozzle number and the identifying information of the first material type, which are read, to the nozzle in— formation manager 16 (Sl 1).
The nozzle number from the modeling data reader 15 is input to the nozzle in— ion manager 16 and thus the nozzle information manager 16 thus reads the material type corresponding to the nozzle number (the second material type) from the nozzle information D1 (see Fig. 5) and outputs the identifying ation of the first material type and the identifying information of the second al type to the material profile manager 17 (S12).
The sets of fying information of the first and second material types from the nozzle information manager 16 are input to the material profile manager 17 and thus the material profile r 17 reads the material profile of the first material type (the first material profile) and the material profile of the second material type (the second al profile) from the material profile D2 (see Fig. 6) and outputs each of the read material profiles to the based correction unit 18 and the inter—layer correction unit 19 (813).
When the material profiles are input from the material profile manager 17 to the layer—based correction unit 18, the layer—based correction unit 18 reads one ter from the data to be corrected ($14) and determines r the parameter is one that s on the material (S 15).
When the parameter is one that depends on the material (YES at step 815), the layer— based correction unit 18 determines whether the parameter value is replaceable from the type of the parameter ($16). For example, when the parameter is a temperature parameter S (see Fig. 9), the based correction unit 18 determines that the parameter value is eable. On the other hand, when the parameter is a pushed-out parameter E (see Fig. 9), the layer-based correction unit 18 determines that the parameter value is not eable. In the latter case, the layer—based correction unit 18 calculates a parameter value.
When the layer—based correction unit 18 determines that the parameter value is re— placeable (YES at step 316), the layer-based correction unit 18 replaces the parameter value with the g value of the second material profile (step 817).
When the layer-based correction unit 18 determines that the parameter value is not replaceable (NO at step 816), the layer—based correction unit 18 replaces the parameter value with a result of a calculation process to be described below. In the calculation process (step 818), the layer—based correction unit 18 calculates a value with which the parameter value is replaced from the setting value of the first material profile, a g value of the second material profile, and a parameter value that is set in the parameter.
A specific example of the calculation process will be described below.
After the process at step 817 and step 818, the layer—based correction unit 18 de— termines whether an unprocessed parameter remains in the data to be corrected (step S19). The layer-based correction unit 18 also performs the ination at step 819 when NO determination is made at step 315.
When an essed parameter s in the data to be corrected (YES at step S19), the process from step S 14 is repeated on the remaining parameter.
When no unprocessed parameter remains in the data to be corrected (NO at step S19), the process ends.
Fig. 14 is a diagram illustrating an exemplary process flow of the ation process represented at the step S18. A process med when the layer—based tion unit 18 reads the pushed—out amount parameter E represented in the fifth row of the modeling data P1 (see Fig. 9) at step S14 will be illustrated as an example.
First of all, the layer-based tion unit 18 reads the ter value of the pushed—out amount parameter E ("5" in this case) that is read at step 814 from the data to be corrected ($21).
The layer—based tion unit 18 then reads the setting value of the filament diameter from the first material profile (822).
The layer—based correction unit 18 then reads the setting value of the filament diameter from the second material profile (S23).
The layer—based correction unit 18 then calculates a value for replacement from the setting value of the filament diameter of the first material profile (the first setting value), the setting value of the filament diameter of the second material profile (the second setting value), and the parameter value ("5") of the pushed—out amount parameter E that is read from the data to be corrected (824).
For example, e that the first material profile is the data d21 of the material name "PLA" (see Fig. 6) and the second material profile is the data d20 of the material name "ABS" (see Fig. 6). In this case, the layer—based correction unit 18 reads the filament diameter "2 mm" as the first setting value from the data d21 and reads the nt diameter "1 mm" as the second setting value from the data d20. The parameter value of the pushed-out amount parameter E is a value in the case where the filament diameter is the first setting value ("2 mm"). After the material type of the filament is changed, the filament diameter is small at the second setting value ("1 mm") and the cross sectional area is reduced to 1/4. In order to e the same pushed—out amount (volume) of the filament, "20" that is four times the parameter value "5" of the pushed— out parameter E is calculated and "20" is used as a value for replacement.
The layer—based correction unit 18 replaces the parameter value with the value for re— placement (S25).
Fig. 15 is a diagram illustrating ary modeling correction data. Fig. 15 il— lustrates a comparative view between the original modeling data and the corrected modeling data (modeling correction data) in the case where the modeling data about ABS resin is corrected based on the ng data P1 about the modeling material (filament) that is PLA resin.
As rated in Fig. 15, in the molding correction data, for the parameters whose ter values are replaceable, the setting values for PLA are replaced with the g values for ABS. For the parameters whose parameter values are not replaceable, replacement with setting values corresponding to ABS is performed by using values for replacement that are calculated by the above—described ation processing.
Fig. 16 is a diagram illustrating an exemplary process flow of the process block B2 of the inter—layer correction process. First of all, the inter—layer correction unit 19 sets a t value "1" for a variable k (S30).
The inter—layer correction unit 19 chooses sets of modeling correction data about a k— th layer and a k+1—th layer (S31). The k+1—th layer is a layer higher than the k layer by one layer.
The inter—layer correction unit 19 determines whether the time required to model the k layer is smaller than the single layer minimum time (S32). Specifically, the inter— layer tion unit 19 calculates a time required for modeling from the modeling tion data about the k—th layer and determines r the time is smaller than a setting time that is set for item k16 of the single layer minimum time of the second material profile (see Fig. 6).
When the time required to model the k—th layer is smaller than the single layer minimum time (YES at step S32), the inter—layer correction unit 19 buries a standby command (an example of "the standby information") for delaying the start of modeling the k+1-th layer by a setting time in the modeling correction data about the k+1-th layer (S33). For a setting time for the standby command, a time enabling the sum of the time required to model the k—th layer and the setting time to be over the single layer m time is set.
When the time required to model the k—th layer is equal to or larger than the single layer m time (NO at step S32), the inter-layer correction unit 19 skips the process at step S33 and determines whether the parameter value of the nozzle tem— perature parameter that is set in the modeling correction data about the k—th layer is larger than that of the k+l—th layer (S34).
When the parameter value of the nozzle temperature parameter of the k—th layer is larger than that of the k+l—th layer (YES at S34), the inter—layer correction unit 19 corrects the parameter value of the nozzle temperature parameter of the k+l-th layer such that the parameter value is close to the ter value of the nozzle temperature parameter of the k—th layer (S35). In other words, the nozzle temperature during the modeling of the k+l—th layer is increased.
When the parameter value of the nozzle temperature parameter of the k—th layer is equal to or smaller than that of the k+l—th layer (NO at step S34), the inter—layer tion unit 19 skips the process at step S35 and determines whether the variable k exceeds the upper limit of the number of layers (S36).
When the variable k does not exceed the upper limit value of the number of layers (NO at step S36), the layer correction unit 19 increments the variable k by one (S37) and performs the processes from step S31. In other words, the inter—layer correction unit 19 performs the inter—layer correction process on the modeling correction data about the layer higher by one layer.
When the variable k exceeds the upper limit value of the number of layers (YES at step S36), the inter layer correction on all the layers has ended and therefore the inter— layer correction unit 19 ends the inter—layer correction process on each layer.
The modeling device 2 may perform part of or all the process of generating modeling data performed by the CAM processing unit 1—1 (see Fig. 1) and the process of correcting modeling data performed by the correction processing unit 1—2 (see Fig. 1).
Second Embodiment Fig. 17 is a diagram rating an exemplary system configuration of a "modeling system" according to a second embodiment. A modeling system X2 illustrated in Fig. 17 is configured to include the ation processing device 1 and the modeling device 2 as the modeling system X1 according to the first embodiment rated in Fig. 1 is. As for the CAM processing unit 1—1 and the correction sing unit 1-2, the CAM processing unit 1—1 is arranged in the ation processing device 1 and the correction processing unit l—2 is arranged in the modeling device 2.

The data ns "the nozzle information D1 (see Fig. 5)" and "the material profile (information) D2 (see Fig. 6).
Functional Configuration Fig. 18 is a m illustrating an exemplary functional configuration of the modeling device 2. As illustrated in Fig. 18, the modeling device 2 includes, as a modeling data output processor, a ng data reader 15a, a nozzle information manager 16a, a material profile manager 17a, a layer—based correction unit 18a, an inter—layer correction unit 19a, and the modeling unit 20a. The components re— spectively have functions corresponding to the modeling data reader 15, the nozzle in— formation manager 16, the material profile manager 17, the based correction unit 18, the inter—layer correction unit 19, and the modeling unit 20a. Descriptions of co— operative ions among the functional units of the information processing device 1 and the modeling device 2 are redundant and thus the descriptions will be omitted herein.
Process Flow The first embodiment represents the example where the process block B1 of the layer—based correction process (see Fig. 12) is performed on all the layers and then the process block B2 of the inter—layer correction process (see Fig. 12) is performed. In the second embodiment, the modeling device 2 is able to modify the order of the process block B1 of the layer—based correction process and the process block B2 of the inter— layer correction s.
Fig. 19 is a m illustrating a modification of the order of the process block B1 of the layer—based correction process and the process block B2 of the inter—layer correction process. As illustrated in Fig. 19, first of all, the layer—based correction process on the first layer (the bottom layer) is med and then modeling data about the first layer after the layer—based correction process is output to the modeling unit 20a.
The layer—based correction s on the second layer (the layer above the first layer) is performed and subsequently the inter—layer correction process on the second layer is performed by using the modeling data after the layer—based correction process on the first layer. Modeling data about the second layer after the inter—layer correction process is output to the modeling unit 20a. Thereafter, similarly, the layer—based correction process on a k—th layer is performed and uently the inter—layer correction process on the k—th layer is performed by using the modeling data after the layer—based correction process on a k—l—th layer. The modeling data about the k-th layer after the inter—layer correction process is output to the modeling unit 20a. The layer-based tion process on a n-th layer (the top layer) is performed and sub- sequently the inter-layer correction process on the n-th layer is performed by using modeling data after the layer—based correction s on a n— l—th layer. The ng data about the n-th layer after the inter-layer correction process is output to the modeling unit 20a.
As described above, the modeling device 2 is able to appropriately modify the order of the process block B1 of the layer—based correction process and the process block B2 of the inter-layer correction process. Because of this modification, the modeling unit 20a need not buffer the modeling data about all the layers and thus it is le to correct molding data even when the memory area is small. Furthermore, the inter—layer correction s is performed on a layer—to—layer basis and this realizes an effect that it is possible to output modeling data sequentially to the modeling unit 20a and thus to start modeling promptly.
