Description of the invention

The idea behind this invention is to develop a unique way of taking orders, online and offline and producing the object of clothing or footwear.

Based on this idea, the technical problem is solved by a process of making an object of clothing or footwear, on a physical mold resulting from the virtual molding.

The process of making an object of clothing or footwear, according to the invention implies that after taking over the order, the client's body will be scanned with a 3D digital scanning system, obtaining a virtual molding, which represents a very precise 3D format reproduction. of the client's body; the molding takes over all the atypical dimensions that cannot be classified in the databases for standard types; next, the virtual molding is transferred to a specialized software from which those 2D digital patterns are chosen, which correspond as closely as possible to the dimensions of the virtual molding; after establishing the 2D pattern, it is transformed into a 3D pattern which is further modified according to the atypical features of the client; the 3D models once chosen are verified on the virtual molding and then transformed into custom 2D patterns that will be transmitted later to production; In the next step, the transformation of the virtual molding into a physical molding takes place on a 1: 1 scale, an operation performed with CNC routers, either with 3D printers, or any other devices that can generate a physical object on scale 1 can be used: 1, respecting all the parameters recorded by the scanner and processed according to the client's figure; follows the step of cutting the materials after the 2D patterns modified according to the virtual molding, which is made manually, or automated, the parts thus designed being directed for assembly, the assembled product being subjected to the verification (sample) stage on the physical molding, whenever or it is needed; after the assembly of the product it will be subject to finishing operations, and after a last verification of it, the finished product is packaged and delivered.

in the case when it is desired to make an object of footwear, after scanning the foot, the physical molding, on which the footwear will be worked, will be made of a material adapted to the requirements of this purpose, under the same conditions and with the same machines, based on the virtual molding, differing only in the material adapted to the requirements of this purpose.

Brief description of the drawings:

Fig. 1 scheme of the procedure in the offline order variant

Fig. 2 diagram of the procedure in the online order variant

Referring to FIG. 1, the process of making an item of clothing in the offline variant involves a first stage of taking over the order. The client will be present at a manufacturer's center, where it is scanned with a 3D digital scanning system, obtaining a virtual MV molding, which represents a very accurate 3D format reproduction of the client's body.

Then the MV virtual molding is transferred to a special software where it is measured and from a standard patterned database, those digital patterns corresponding to the made object / footwear are selected. With that software the 2D patterns in the database are transformed into 3D patterns.

The next step is to modify the chosen 3D patterns, depending on the particularities of the body identified and confronted with the virtual MV molding created. This will result in custom patterns. These 3D patterns, once selected and verified on the MV virtual molding are transformed into custom 2D patterns that will be transmitted later to production.

In the next stage, the custom molding MF is made physically. Thus the information obtained from the scan is taken, and on the basis of this information the transformation of the MV virtual molding into a physical molding MF is performed, on a 1: 1 scale.

The physical molding (MF) is made with CNC router, either 3D printers, or any other device that can generate a physical object on a 1: 1 scale, following all the parameters recorded by the scanner and processed according to the client's silhouette.

If it is desired to obtain an object of footwear, after scanning the foot, the physical molding (footwear) MF on which the footwear will be worked, will be made of a material adapted to the requirements of this purpose, under the same conditions and with the same machines mentioned above. above, based on the MV virtual mold (calapod), differing only by the material adapted to the requirements of this purpose.

The next steps of the process consist in cutting materials according to the 2D patterns modified according to the virtual molding, which is made traditionally or manually, or by an automated cutting table. The markings thus drawn are directed to the confectioner who performs their assembly, correlated with the worksheets, the assembled product being subjected to the verification stage (sample) of the physical molding MF, whenever necessary.

After assembly, the product will be subjected to finishing operations, and after a final verification, it is packaged and delivered.

The process of making a garment in the online version according to fig. 2, assumes that the scan is performed directly by the client, at a specialized scanning center, or at home, with its own scanning devices, and with the data obtained, creating a virtual MV molding itself. The personalization of the products is realized directly by the customer on the virtual MV molding created, on a site dedicated to the personalization of the products, choosing from a database, different variants of cuts, textures, sleeves etc.

After the customization is completed, the MV virtual molding and the customized product are transmitted to the manufacturer, following which he will realize the physical molding MF based on the information received from the customer.

The following steps involve establishing 2D patterns according to the physical molding made by MF, followed by the manufacturer's manufacturing of the desired product and customized according to customer preferences. The manufacturer, based on the worksheets, will check the assembled product (sample) on the MF physical mold, whenever necessary.
