Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0029] refer to Figure 1 to Figure 3 As shown, a 3D printing last forming method of this embodiment includes

[0030] Step 1, download the required shoe last model, modify the data of the shoe last model with drawing software and convert the data of the shoe last model into the format required by the 3D printer;

[0031] Step 2, output the shoe last data to the 3D printer and print out the required shoe last;

[0032] Step 3, select the midsole and heat insulation film of the corresponding size, put the heat insulation film on the shoe last and nail the midsole to the bottom of the shoe last;

[0033] Step 4, put the upper into the last, and use nails to fix the upper on the last and the midsole;

[0034] Step five, use a hammer to smooth the upper, then use glue to bond the midsole and the upper of the upper, and then pull out th...

Abstract

The invention discloses a 3D printing shoe-last forming method. The 3D printing shoe-last forming method comprises the steps that 1, a required shoe-tree model is downloaded, and a data format is modified; 2, shoe-tree data is output to a 3D printer, and a required shoe tree is printed; 3, an insole with the corresponding size and a heat insulating film with the corresponding size are selected, the shoe tree is sleeved with the heat insulating film, and the insole is nailed to the bottom of the shoe tree; 4, the shoe tree is sleeved with a shoe upper, the nails are used to fix the shoe upper to the shoe tree and the insole; 5, the shoe upper is repaired to be smooth through a hammer, then the insole and a lasting allowance of the shoe upper are bonded through glue, and then the nails are pulled out; and 6, a combining body of the shoe tree, the insole and the shoe upper is placed into a microwave oven for heating and sizing. According to the 3D printing shoe-last forming method, heating and sizing through the microwave oven can make the situation that a shoe last printed through a 3D printer can be manufactured into a shoe to be possible, and the heating and sizing time is greatlyreduced; and through the selective heating characteristic of the microwave oven, only the shoe upper is heated, and the shoe tree is not heated, so that swelling or melting of the shoe tree does not occur, and thus the sized upper part is more accurate.

Description

technical field [0001] The invention relates to a sample preparation method for making shoe lasts by applying 3D printing rapid prototyping technology, in particular to a sample preparation method for shaping by microwave. Background technique [0002] With the development of technology, more and more shoe designers start to use computer software, and designers can design the layout of the last through computer software. Although the computer data-based version has the advantages of high efficiency and low cost, when the designer outputs the last, he still needs to hand over the virtual last file to the last factory and engrave it through the CNC machine of the last factory. Carving a single design last has relatively high requirements on the material cost and labor equipment of the last factory. [0003] With the development of technology, 3D printing rapid prototyping technology has become popular at home and abroad. 3D printing rapid prototyping technology not only has l...
