Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

Examples

Referring to fig. 1 and 2, an FDM type 3D printing sole includes a sole main body 2, the sole main body 2 is formed by stacking a plurality of sole main body layers on a printing plane 1, the sole main body 2 is provided with at least one hollow portion 21, and an included angle between a suspended surface of the hollow portion 21 and a horizontal plane is not less than 30 degrees.

Sole main part layer includes contour line 22 and a plurality of filling line 23, contour line 22 encircles and forms single closed loop figure, and a plurality of sole main part layers pile up for contour line 22 forms the main part outer wall, and the main part outer wall can play the effect that keeps the clean and tidy smooth appearance, in order to strengthen the stability at sole main part edge, can also be with the thickness that increases the main part outer wall to the mode of many contour lines of bonding along the level.

The filling lines 23 are arranged in the closed loop patterns of the contour lines 22, the filling lines 23 are staggered to form plane patterns, meanwhile, the plane patterns formed by the filling lines of different sole main body layers can also be staggered, so that the filling area can be ensured to have high elasticity and support property, less processing time and less materials are needed, and the plane patterns formed by the filling lines are one or a combination of several of honeycomb, grid, diamond, triangle or concentric circles.

Referring to fig. 4, for convenience of description, the filling structure formed by the plurality of filling lines is simplified into two grid structure layers, wherein the first grid structure layer is formed by the plurality of parallel filling lines, the second grid structure layer is formed by the plurality of parallel filling lines, the filling lines of the first grid structure layer and the second grid structure layer are arranged in a staggered manner to form a structure which is staggered in a transverse and longitudinal direction, on the premise that less processing time and less materials are needed, the grid density is higher, meanwhile, suspended bridging lines exist between the layers, and bonding points between the layers are arranged in a staggered manner, so that the problem of foot damage is avoided, and the supporting property is ensured while the filling structure has high elasticity.

Referring to fig. 5, since the FDM type 3D printing process is a layer-stacking process, similar to the principle of building, the upper extrusion line 212 must be partially adhered to the edge of the lower extrusion line 211 to prevent the extrusion line from falling off, when the contour lines are in a single-layer structure, half of the upper extrusion line 212 overlaps the lower extrusion line 211 in the width direction, and the included angle between the upper extrusion line 212 and the lower extrusion line 211 and the horizontal plane is 45 degrees, in order to make the included angle between the upper extrusion line 212 and the horizontal plane smaller, the contour lines need to be in a double-layer structure, i.e. one inner contour line is printed in the horizontal plane direction, one outer contour line is printed outside the inner contour line, the first outer contour line 221 is connected with the first inner contour line 2211 to form a lower double contour line, and then the second outer contour line 222 is connected with the second inner contour line 2221 to form an upper double contour line in the same way, wherein the double-contour line of lower floor overlaps 25% to 30% with the double-contour line of upper strata, can make the angle of inclination littleer, reaches 30 degrees to the realization fretwork portion unsettled surface is not less than 30 degrees with the contained angle of horizontal plane, can guarantee shoe-pad overall structure intensity simultaneously.
