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 3D model of the spectacle frame to be manufactured which comprises at least a plurality of forms and lines of the frame front of the spectacle frame;
providing a 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;
adapting the 3D model of the spectacle frame to the 3D model of the head of the spectacle wearer;
preventing the forms and lines of the frame front from being deformed while the 3D model of the spectacle frame is being adapted to the 3D model of the head of the spectacle wearer; and
manufacturing the frame front of the spectacle frame based on the 3D model of the spectacle frame after being adapted to the 3D model of the head of the spectacle wearer,wherein providing the 3D model of the spectacle frame to be manufactured comprises;
providing a plurality of 3D models of the spectacle frame to be manufactured, each of the plurality of 3D models of the spectacle frame comprising a different width, at least the frame front of the spectacle frame, and at least one part of the spectacle frame which is to be in contact with the 3D model of the head of the spectacle wearer that is over dimensioned; and
selecting a 3D model of the spectacle frame from the plurality of 3D models of the spectacle frame to correspond to a width of the head of the spectacle wearer,wherein adapting the 3D model of the spectacle frame to the 3D model of the head of the spectacle wearer comprises;
positioning the frame front of the selected 3D model of the spectacle frame in a desired position of wear relative to the 3D model of the head of the spectacle wearer in a virtual environment so that the 3D model of the head of the spectacle wearer intersects a rear side of the frame front of the selected 3D model of the spectacle frame; and
cutting a portion out of the rear side of the frame front of the selected 3D model of the spectacle frame along an intersecting plane of the frame front of the selected 3D model of the spectacle frame and the 3D model of the head of the spectacle wearer in order to adapt the frame front of the spectacle frame to be manufactured to the spectacle wearer, wherein the portion cut out of the rear side of the frame front of the selected 3D model of the spectacle frame corresponds to a portion of the frame front which makes contact with a nose of the spectacle wearer, andwherein manufacturing the frame front of the spectacle frame based on the 3D model of the spectacle frame after being adapted to the 3D model of the head of the spectacle wearer comprises;
maintaining an unadapted front side of the frame front; and
forming the rear side of the frame front according to the portion removed of the rear side of the frame front of the selected 3D model of the spectacle frame.

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.
