The price of Bronze is directly related with the volume of the model to print. There is a flat fee for small models up to 8 grams (±1 cm³). There is no extra charge for PU coating.
Bronze can typically be used for detailed miniatures, sculptures, jewelry or preprint tests (e.g. to form-fit before ordering Gold or Silver).
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 Bronze. 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 Bronze is poured in to fill the cavities left by the wax. Once the Bronze has cooled and solidified, the plaster mold is broken and the Bronze 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.
Learning about our materials is one thing, seeing and touching them another. That's why we've designed sample kits based on our Periodic Table of Materials.
