Description

Technical Field

[0001] The utility model belongs to the technical field of shoes, and in particular relates to a 3D printed shoe which is easy to put on and take off. Background Art

[0002] 3D printing, also known as additive manufacturing, is a new manufacturing method that began in the 1980s. After more than 30 years of development, the technology has become relatively mature. Currently, 3D printing has been widely used in the production and manufacturing of shoes.

[0003] At present, the shoes printed by 3D printing technology and the shoes obtained by partial 3D printing technology mainly use closed heels. In product design, closed heel shoes need to use shoelaces, adhesive strips or zippers on the upper to facilitate the wearing and taking off of the shoes, but the use of shoelaces, adhesive strips or zippers will increase the production process of shoes and increase costs. In order to replace shoelaces, adhesive strips or zippers, there is a solution in the prior art that uses a softer upper to facilitate wearing and taking off. This solution has higher engineering requirements and design restrictions on the upper, and shoes with such uppers need to repeatedly stretch the shoe opening when putting on and taking off, which reduces the wearing and taking off experience, and may even cause the upper or the upper opening to tear.
