The pricing for Silver is based on model volume, which is the volume of your model used to calculate the material cost (mm³).
Additionally, a startup cost is applied to the price of your model. This is a fixed cost independent from the parameters of your model. If you order two or more copies of a model, the price automatically decreases because the preparation of multiple copies can be carried out more efficiently.
Silver is mainly used for jewelry and ornamental items. You could also try to make circuits and mirrors from it but most of our designers use this for jewelry pieces such as individualized rings, earrings, and bracelets.
Wax 3D printing and lost wax casting are used to build your design when using this material. The wax printing process is a type of Stereolithography that uses a wax-like resin. Support structures are printed along with the model to make sure your model doesn’t fall apart. These support structures are automatically generated and manually removed after the printing process. After support structures are removed and your model is cleaned, the model can be prepared for casting.
First, one or more wax sprues will be attached to your model. Next, it will be attached with the sprue to a wax ‘tree’, together with a bunch of other models. The tree is then placed in a flask and covered in a fine plaster. When the plaster solidifies, it forms the mold for casting the Silver. The plaster mold is then put in an oven and heated for several hours to a point where the wax is completely burned out.
Then, the molten Silver is poured in to fill the cavities left by the wax. Once the Silver has cooled and solidified, the plaster mold is broken and the Silver models are removed by hand. Finally, your model is filed and sanded to get rid of the sprues. It will be sanded, polished or sandblasted for the finish you desire.
