Brass is an alloy of copper and zinc. You probably know it from the many musical instruments that are made out of Brass because of its acoustic properties and ductility. It is used in a wide range of applications where people are looking for a more economical replacement for precious metals. Our Brass is plated to have that 18kt goldish look and can have the same level of detail as our Silver and Gold. A PU coating provides extra protection to the plating, enabling us to offer a 6 months guarantee for the plating.

Pricing Info

The price of Brass is directly related to the volume of the model to print. The bigger the model volume, the less you pay per cm³. Electroplated brass models cost about 5 EUR more per model than the natural PU coated color.

Gold plating prices:

  • 1 cm³ costs about 25 EUR
  • 5 cm³ costs about 95 EUR
  • 10 cm³ costs about 160 EUR

Typical Use

Brass can be typically used for detailed miniatures, sculptures, jewelry or preprint tests (e.g. to form-fit before ordering Gold or Silver). The material is perfect if you want your piece to bling as Gold but you don’t want to spend so much money.

Technology

Wax 3D printing and lost wax casting

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 Brass. 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 Brass is poured in to fill the cavities left by the wax. Once the Brass has cooled and solidified, the plaster mold is broken and the Brass 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.

Additional Information

  • Structures such as a “ball within a ball” cannot be made with this process.
  • Links of chains for example can also not be made with this process.
  • Brass oxidates in a greenish way if not plated or varnished
