Method for Manufacturing a Spectacle Frame Adapted to a Spectacle Wearer
First Claim
1. Method for manufacturing a spectacle frame adapted to a spectacle wearer, wherein the spectacle frame comprises a frame front and frame temples, and the method comprises the steps of:
- providing a collection of virtual 3D models of the spectacle frame to be manufactured with different widths of the spectacle frame, these 3D models comprising at least the frame front of the spectacle frame;
choosing a virtual 3D model from the collection of virtual 3D models on the basis of the width of the head of the spectacle wearer in order to adapt the width of the spectacle frame to be manufactured to the width of the head of the spectacle wearer;
providing a virtual 3D model of the head of the spectacle wearer, which comprises at least a part of the head of the spectacle wearer which is in contact with the frame front when the spectacle frame is being worn;
positioning the frame front of the chosen 3D model of the spectacle frame in a desired position of wear relative to the 3D model of the head in a virtual environment so that the 3D model of the head intersects the rear side of the frame front of the chosen 3D model of the spectacle frame where the frame front of the spectacle frame is worn on the nose of the spectacle wearer in the desired position of wear;
cutting a portion out of the rear side of the frame front of the chosen 3D model of the spectacle frame along the intersecting plane of the frame front of the chosen 3D model of the spectacle frame and the 3D model of the head in order to adapt the frame front of the spectacle frame to be manufactured to the spectacle wearer; and
manufacturing the frame front of the spectacle frame on the basis of the chosen 3D model of the spectacle frame, wherein the frame front has an unadapted front side with the original forms and sizes of the chosen 3D model and the frame front has a rear side adapted by means of the cut-out portion.

Abstract
The present invention relates to a method for manufacturing a spectacle frame adapted to a spectacle wearer, particularly by means of 3D printing or other additive manufacturing techniques. The present invention provides for this purpose a method comprising the steps of providing a virtual 3D model of a spectacle frame; providing a virtual 3D model of the head of the spectacle wearer which comprises at least a part of the head of the spectacle wearer which is in contact with the spectacle frame when the spectacle frame is being worn; positioning the 3D model of the spectacle frame relative to the 3D model of the head in a virtual environment so that the 3D model of the head intersects the 3D model of the spectacle frame where said part of the head of the spectacle wearer is in contact with the spectacle frame when the spectacle frame is being worn; cutting a portion out of the 3D model of the spectacle frame along the intersecting plane of the 3D model of the spectacle frame and the 3D model of the head; and manufacturing at least a part of the spectacle frame on the basis of the part of the 3D model of the spectacle frame from which the portion has been cut.
