🖨️ For 3D Printing

  • Check the model orientation for optimal print quality and minimal support usage.
  • Add supports where needed, especially for overhanging details.
  • Set your desired scale — all files are modeled in millimeters (mm).
  • Slice and export to your 3D printer.

💎 For Lost-Wax Casting

  • Check the product description and inspect the model's wall thickness and construction before printing. Confirm suitability for your chosen resin, metal, and casting process.
  • 3D print the model using a high-resolution castable resin printer.
  • Follow standard lost-wax casting procedures for your metal of choice.
  • Finish, polish, and set stones as desired.
