Title:
METHOD OF FABRICATING LAST
Document Type and Number:
WIPO Patent Application WO/2017/078168
Kind Code:
A1
Abstract:
The objective of the present invention is to use a 3D printer to fabricate, in as short a time as possible, a last that can be used when manufacturing a shoe.
(i) The surface shape of the last is determined on the basis of three-dimensional data obtained by measuring the three-dimensional shape of a foot, (ii) a contour part (12) having an empty space (13) therein is molded using a 3D printer in such a way that the determined surface shape matches the shape of the outer surface (12y) of the contour part (12), (iii) when molding of the contour part (12) is complete, or when the contour part (12) has been partly molded, the inside thereof is filled with uncured filler (15). A last (10) including the contour part (12) and the cured filler (15) in contact with the inner surface of the contour part (12) is fabricated in this way.
