1. Introduction

In this article, we will explore the process of transforming a CAD model into a physical ring using 3D printing and traditional jewelry making techniques. We will cover each step in Detail, discussing the tools and materials required, as well as offering tips and tricks along the way. Whether You are a beginner or an experienced jeweler, this guide will provide valuable insights into creating a stunning piece of jewelry.

2. 3D Printing

To begin the production process, we will first discuss the use of 3D printing. There are various types of 3D printers available, but we will focus on the B9 Creation printer for this demonstration. We will examine the result image obtained from the 3D printing process and discuss how to remove the printing lines using sandpaper.

3. Finishing the Printed Model

Once the 3D printing is complete, we will move on to the finishing process. This involves removing any excess material, such as the sprue, and ensuring that the surface of the model is smooth and polished. We will discuss the importance of sandpaper and its role in achieving the desired finish.

4. Sanding the Model

Using homemade sandpaper, we will demonstrate how to sand the model to remove any remaining printing lines. We will guide you through the steps of wrapping a stick with sandpaper and ensuring a flat and tight surface for effective sanding. Additionally, we will discuss the grits of sandpaper to use and when to transition to finer grits.

5. Using Homemade Sandpaper

In this section, we will provide a detailed explanation of creating homemade sandpaper by wrapping a stick with 280 grit sandpaper. We will discuss the technique of smoothing out the rough areas of the model, focusing on the outside surface. We will also touch upon the importance of achieving a polished finish before proceeding with the stone setting.

6. Polishing Machine

Moving on to the polishing process, we will introduce the use of a polishing machine to further refine the finish of the ring. We will highlight the different compounds used and explain how each contributes to achieving a professional polish. We will also provide recommendations for sourcing the necessary polishing supplies.

7. Using a Brown Polish Wheel

In this section, we will Delve deeper into the use of a brown polish wheel for polishing the ring. We will discuss its abrasive qualities and the benefits it offers in removing minor scratches. It is important to exercise caution when using an abrasive wheel, especially when working with heat-sensitive stones like opal.

8. Cleaning the Inside of the Model

While the outside surface requires meticulous polishing, the inside of the model may need some Attention as well. We will discuss how to clean up any rough surfaces left from the casting process. Although opaque stones do not require polishing on the inside, we will explain the importance of removing any bumpy surfaces for a smooth and comfortable fit.

9. Shaping the Ring Shank

Using a ring mandrel and a plastic hammer, we will demonstrate how to Shape the ring shank. We will explain the process of tapering down the shank to ensure a smooth and comfortable fit. Additionally, we will discuss the use of a file, specifically a half-round file, to further refine the shape and smooth out any imperfections.

10. Smoothing Out the Bottom

In this section, we will focus on smoothing out the bottom of the ring. Often, the area where the sprue was cut off tends to be rough. To ensure a seamless finish, we will discuss the technique of using a rubber wheel to shape and smooth out the bottom. We will also provide guidance on shaping the rubber wheel to suit your specific needs.

11. Filing and Smoothing the Ring

Continuing with the shaping and smoothing process, we will explore the use of filing to fine-tune the ring's shape. Specifically, we will emphasize the importance of rounding the corners to prevent discomfort or irritation when the ring is worn. We will also mention the option of using an old file to shape the rubber wheel for more precise shaping.

12. Fit Testing the Ring

Before proceeding with the stone setting, it is crucial to ensure that the ring fits properly. We will guide you through the process of fitting the ring and checking for any adjustments needed. By providing a comfortable and secure fit, we can guarantee the longevity and wearability of the finished piece.

13. Buffing the Ring

To achieve a high polish on the ring, we will demonstrate the use of a buffing wheel. We will discuss the different polishing compounds used, including the white diamond and Fabuloustre compounds. These compounds are essential for achieving a Flawless finish, as they remove any remaining hammer marks and elevate the overall aesthetic of the ring.

14. Stone Setting

In this section, we will dive into the intricate process of setting the stone into the ring. We will begin by examining the thickness of the wall and the challenges it presents for stone setting. We will discuss the use of Parallel pliers to bend the wall and Create a secure setting for the stone.

15. Bending the Wall

To ensure a snug fit for the stone, we will demonstrate how to bend the wall of the ring using parallel pliers. This technique allows for precise control and ensures that the stone can be securely set within the ring. We will provide visual references and offer tips for achieving the desired shape and fit.

16. Hammering the Wall

With the wall bent, we will move on to the delicate process of tightening the stone setting. We will discuss the use of a hammer to gently tap the wall and secure the stone in place. We will stress the importance of caution, as excessive force or improper angles can result in a cracked stone. We will share a valuable tip for protecting the stone during this step.

17. Polishing the Ring

Once the stone is securely set, we will revisit the polishing process to remove any hammer marks and create a seamless finish. We will use the rubber wheel to refine the angles and shape of the ring, ensuring a comfortable fit and a professional appearance. We will highlight the need to monitor the temperature of the ring and exercise caution when using heat-generating tools.

18. Final Touches

In this section, we will bring the ring to its final polish, using the white diamond and Fabuloustre compounds. We will emphasize the importance of achieving a high polish before completing the stone setting. By removing any remaining imperfections and ensuring a flawless finish, we can enhance the overall appearance and value of the ring.

19. Conclusion

In conclusion, this article has provided a comprehensive guide to the production process involved in transforming a CAD model into a physical ring. We have explored each step, from 3D printing and finishing the printed model to stone setting and final polishing. By following these techniques and tips, you can create stunning and professional pieces of jewelry that will be cherished for years to come.
