CAD designing

At Dear Rae, we’re all about handcrafted treasures. But there are however times that call for CAD (computer aided design). This is especially true when creations require a very high level of intricacy and/or the client wishes to be involved in the design process from start to finish.

What is it?

CAD uses computer software to create pieces that require very specific design, materials and dimensions. This can be done in two dimensional and three dimensional design. Special 3D printers are used to print resin replicas of the design, which is then cast in precious metal.

How does it help me?

The great thing about CAD is that files and renderings can be shared with you during the process so that changes can be made before the ring is cast. As you can imagine, making changes to the piece after it’s been cast is obviously a lot more difficult, not to mention time consuming.

Which designs is it used for?

Pieces that require CAD are usually halo, cluster or trilogy rings. We also prefer using CAD for most of our rose gold engagement rings because the solder available for rose gold has a yellow tone and shows up on the metal. Because casting is part of the CAD process, solder seams and colours differences are not an issue.

What is the process?

All CAD designs and castings are outsourced to two companies we’ve been working with closely for the last 4 years.

  1. We send a comprehensive description, along with supporting images and sketches to the CAD designer.
  2. They design the piece in a program called Rhinoceros and then sends us the design files and renderings.
  3. We then share these with you and together we decide whether any changes need to be made.
  4. Once we have given approval, the CAD designer prints the resin mould, which is then cured and cast in gold.
  5. Once we receive the casting, we work the piece off by hand and prepare it for the setter.
  6. The ring is then set and polished, and ready for you to collect.

This process can take up to 4 weeks.

Finished product

All pieces are worked off by hand, which means that the finished product will appear less mechanical than it did in the renderings and when cast.
