Definitions

  • the invention relates to a method for producing a three-dimensional structure, in particular footwear.
  • the invention also relates to a module for a computer unit for carrying out such a method.
  • the invention relates to a three-dimensional structure, in particular footwear or a part of footwear such as insoles, footbeds, insoles, models, shoe bottoms, etc.
  • Insole fittings are currently mostly made using insole blanks, individually milled insoles or insoles using the deep-drawing process.
  • the material used is mostly EVA. This is available in different Shore hardness levels. Different Shore hardnesses can be combined with one another using so-called sandwich materials. However, one is dependent on the different material thicknesses in order to map characteristic value ranges. Additional padding or supports have to be incorporated into the insole at great expense and subsequently. Insoles etc. manufactured in this way still require post-processing before they can be placed in the shoe.
  • the object of the present invention is therefore to create a method tailored to the respective user for producing footwear or parts of footwear or other applications of a shoe and a module for a computer unit for carrying out such a method.
  • This object is achieved in that a template of the workpiece is divided into a large number of grids and each of these grids is assigned an individual characteristic value with regard to at least one of its physical properties.
  • Such a template serves as a kind of prototype for later production of a three-dimensional structure.
  • a computer unit subdivides the workpiece into a large number of grids, with each of these grids being assigned an individual material parameter (e.g. in relation to its hardness), so that there are significantly better distribution options for these values across the insole and a perfect template for later large-scale production has been created.
  • the individualization of the seat surface with an optimal distribution of individual material parameters is in the foreground.
  • a central application of the present invention relates to tools in the form of footwear and parts thereof, in particular shoes, footbeds for shoes, shoe bottoms, models, insoles,
  • the production is carried out by applying material layer by layer.
  • Such methods which are also referred to as 3D printing, are playing an increasingly important role in the production of three-dimensional structures. They are particularly characterized by high precision, great effectiveness and low unit costs.
  • workpieces of comparatively high complexity can be manufactured.
  • Known 3D printers generally include a heatable work surface. A plastic filament is heated and fed to the extruder. In this respect, spatial structures can be traced through movements, which lead from sculptures to very complex constructions.
  • Another preferred method relates to selective laser sintering as an alternative to that described.
  • a template for footwear or parts thereof is divided into a large number of three-dimensional grids or if such a template is divided into a large number of grids of the same structure, also with a view to a standard created in this way.
  • the present invention aims at footwear or parts thereof.
  • the hardness is of central importance, which could only be specified and maintained very roughly using previously known methods.
  • the material parameter in the context of the method according to the invention thus revolves around the hardness, expediently the Shore hardness of footwear or parts thereof, and also around the material parameters damping and restoring force.
  • Such workpieces are characterized by optimized rigidity, strength and, above all, hardness as well as targeted padding and the associated relief.
  • a preferred variant of the invention provides that the grids are created with a resolution of approximately 2 mm ⁇ 2 mm ⁇ 2 mm to 15 mm ⁇ 15 mm ⁇ 15 mm, preferably with a resolution of 3 mm ⁇ 3 mm ⁇ 3 mm up to 8mm x 8mm x 8mm.
  • These grids can be optimized with regard to the dimensioning of soles etc. and grids if the grids are created with a resolution of 5 mm x 5 mm x 5 mm and consequently in the form of a cube or a cuboid.
  • a module for a computer unit for carrying out the method described is used, also referred to as a parameter selection module, in particular a Shore hardness selection module.
  • This module is assigned to a computer unit with appropriate handling, such as via displays, which is fed with the appropriate data regarding the design and shape of the template, desired degrees of hardness of the entire sole or parts of it.
  • the computer unit then generates the final template, taking these requirements into account, and it is passed on to a Printing unit or the conversion of this data into commands for 3D printing as the preferred application.
  • the object according to the invention is also achieved by a three-dimensional workpiece produced using the method according to the invention.
  • the invention is characterized in particular by the fact that a method for producing an insole for a shoe with different shore hardnesses is created, which can thus be individually adapted to each foot.
  • the computer divides it into fine grids of e.g. 5 mm x 5 mm x 5 mm, which can be implemented at each individual point of the insert. There are no noticeable transitions between the degrees of hardness.
  • the demanding printing of soft structures and materials is to be simplified with the method according to the invention.
  • the aim is to obtain a ready-to-sell, printed insert that can be given to the customer without post-processing.
  • a closed bottom is z. B.
  • the sandwich construction z. B. be implemented in the field of diabetes-adapted footbeds. This means that the layers of hard/firm at the bottom of the insole become softer and softer towards the foot.
  • the layers of the insole can be selected in the side view and assigned a degree of hardness accordingly.

It is possible that a box is drawn up and a Shore hardness is explicitly defined for it. The Shore hardness is thus distributed over the entire area of the insert 1. The computer then calls up the area that is to be visualized using the grid.
