Method for digital manufacturing of jewelry items
View Patent ↗In various embodiments, digital manufacturing of jewelry items is provided, including a physical process and software automation for implementing the physical process. Further, models formed during the process, as well as the resultant jewelry items, are provided. In some embodiments, the method comprises forming a digital model of the jewelry item, forming a physical model of the jewelry item based on the digital model, and manufacturing the jewelry item in a lost wax process using the physical model.
1. A method for digital manufacturing of a sized jewelry item comprising:
forming a digital model of the sized jewelry item, the forming a digital model comprising:
creating a three-dimensional digital model of a customization component by creating a toolpath based on CAD data and computing a surface of a volume that would be removed by a cutting tool following the toolpath;
providing a three-dimensional digital model of a generic component by selecting a sized three-dimensional digital model of a generic component from a plurality of stock three-dimensional digital models of generic components; and
combining the digital model of the customization component and the selected digital model of the generic component using a Boolean operation to form a three-dimensional digital model of the sized jewelry item;
forming a sized physical model of the sized jewelry item based on the digital model of the sized jewelry item; and
manufacturing the sized jewelry item in a lost wax process using the physical model.
2. The method of claim 1 , wherein the digital model of the customization component includes a format suitable for combining with other digital models.
3. The method of claim 2 , wherein the format is STL.
4. The method of claim 1 , wherein creating a digital model of a customization component comprises taking a plurality of CAD curves and surfaces, creating a toolpath from the plurality of CAD curves and surfaces wherein the toolpath removes a volume from a base piece, and computing a surface of the volume to be removed by a cutting tool following the toolpath.
5. The method of claim 4 , wherein creating a toolpath is done using CAM software.
6. The method of claim 1 , wherein creating a digital model of a customization component comprises extracting a plurality of curves and surface from a CAD model, extruding the plurality of curves and surfaces to create a volume, and calculating a surface geometry of the volume.
7. The method of claim 1 wherein forming a physical model of the jewelry item comprises printing a solid wax model including a build wax model and support wax, and treating the solid wax model to remove the support wax and expose the build wax model.
8. The method of claim 7 , further comprising treating the build wax model to strengthen the build wax.
9. The method of claim 1 , wherein the jewelry item is a class ring.
10. The method of claim 9 , wherein the generic component is a ring shank.
11. A method for digital manufacturing of a jewelry item comprising:
forming a digital model of the jewelry item, the forming a digital model comprising:
creating a three-dimensional digital model of a customization component by creating a toolpath based on CAD data and computing a surface of a volume that would be removed by a cutting tool following the toolpath;
providing a three-dimensional digital model of a generic component; and
combining the digital model of the customization component and the digital model of the generic component using a Boolean operation to form a three-dimensional digital model of the jewelry item; and
manufacturing the jewelry item based on the three-dimensional digital model of the jewelry item using a rapid prototyping process.
