Jewelry Wax models are produced with sterolithography. Because of the high cost of rapid prototyping equipment and the high level of technical expertise required to reliably produce perfect parts, the trend is to use specialized third-party service bureaus.

We offer reduced time and cost for jewelry designers and their clients with state-of-the-art technology. Our machines build models from computer files using thermoplastics that are perfect components for investment casting.

In the past jewelry design was greatly hindered by difficult communication between the customer and the jeweler. The only option for executing a jewelry design was looking through a stock jewelry design catalogue. Whenever the customer had a vision or idea which was not realized in the finished piece of jewelry the sale became very difficult.

With the aid of computer aided 3d design (cad) model making has taken a wonderful new direction. With us jewelry stores and jewelry customers can actually see their idea before the creation stage. Other important benefits to cad jewelry design is accuracy and affordability. Your jewelry design can now be manufactured with incredible symmetry because the wax model is created using our in house rapid prototyping (rp) machines.

Our systems reduce cost and time-to-market by translating CAD Designs into hard copy 3D models. These models are so accurate that designers can go beyond concept modeling to produce tooling grade patterns ready for casting or mold-making.

Jointly CAD/CAM allows the design of jewelry using a computer (CAD) and creates an exact hard copy model of a jewelry piece using a computer controlled manufacturing device (CAM). Our technicians utilize all file types compatible with any CAM device, which allows us to quickly generate a precise wax model ready for casting.

Stereo lithography and these other hard model technologies are the future of the jewelry industry. Leading jewelers effectively use CAM "service bureaus" that specialize in prototype output.

Gold castings can be made of the wax model itself, the direct method; or of a wax copy of a model that need not be of wax, the indirect method. These are the steps for the indirect process:

Model-making. An artist or mold-maker creates an original model from wax, clay, or another material. Wax and oil-based clay are often preferred because these materials retain their softness.

Mold making. A mold is made of the original model or sculpture. The rigid outer molds contain the softer inner mold, which is the exact negative of the original model. Inner molds are usually made of latex, polyurethane rubber or silicone, which is supported by the outer mold. The outer mold can be made from plaster, but can also be made of fiberglass or other materials. Most molds are at least two pieces, and a shim with keys is placed between the two halves during construction so that the mold can be put back together accurately. In case there are long, thin pieces sticking out of the model, these are often cut off of the original and molded separately. Sometimes many molds are needed to recreate the original model, especially large ones.

Once the mold is finished, molten material is poured into it and swished around until an even coating, usually about 1/8 inch or 3 mm thick, covers the inner surface of the mold. This is repeated until the desired thickness is reached. Another method is filling the entire mold with molten wax, and let it cool, until a desired thickness has set on the surface of the mold. After this the rest of the wax is poured out again, the mold is turned upside down and the wax layer is left to cool and harden. With this method it is more difficult to control the overall thickness of the wax layer.

Removal of wax. This hollow copy of the original is removed from the mold. The technician may reuse the mold to make multiple copies, limited only by the durability of the mold.
