Abstract
The invention relates to a method for designing and 3D printing a shoe (100), wherein said shoe (100) comprises a plurality of outer surface areas (101, 102, 103) with different outer surface properties. The method comprises the steps of capturing design input data for a 3D shoe model defining the plurality of different surface areas (101, 102, 103); slicing the 3D shoe model based on the design input data with infill structures (131) at the different surface areas and based on a shoe size with an individual slicing model for said shoe size; and printing the shoe in a print cycle based on the individual slicing model and the respective shoe size.
Claims26
A method for three-dimensional (3D) printing a shoe, within a print cycle,
- wherein said shoe comprises a plurality of portions arranged along an outer surface of an upper of the shoe,
- wherein the plurality of portions comprise a first portion and a second portion located directly adjacent to each other along the outer surface of the shoe comprising different outer structures,
- wherein the first portion comprises an open outer structure, and
- wherein the second portion comprises a closed outer structure,
- the method comprising additively printing the shoe layer-by-layer,
- wherein at least one printing layer defines the outer surface of the shoe, an inner surface of the shoe, and an intermediate section which connects the outer surface and the inner surface by an infill structure,
- wherein the infill structure at the first portion and second portion is substantially the same and comprises a plurality of infill connecting lines connecting a point adjacent to the outer surface with a corresponding point on the inner surface.
