Wires must be at least 0.8mm thick
Thin wireframe models are difficult to print and fragile in Bronze. Be sure to make the wires at least 0.8mm thick, like in the ring shown here. If wires are too thin, they may snap during the manufacturing process or deform from wear.
Ring bands and pendant loops should be at least 1mm thick
When designing a ring in Bronze, make the band (the part that goes around the finger) at least 1mm thick to prevent it from deforming or breaking when you wear it.
Avoid long unsupported stone holding prongs
Prongs for holding stones cannot be too long without any support structure. Supports and connecting beams prevent wax from breaking in the production process, and allow the final model to hold the stones securely.
Some detail is lost during polishing and plating
Polishing gives this Bronze a beautiful finish, but can have an impact on fine details. During the polishing step, fine or sharp-edged details may be polished down or even broken off. Keep this in mind when you’re designing fine details.
Internal detail can not be polished
We can only polish well-reachable surfaces, so tight internal spaces may remain unpolished.
Include escape holes for hollow models
Hollow parts need openings so we can get out the support material used in printing, and pour in the plaster used in casting. For models with one escape hole, the opening must be greater than 4mm in diameter. For models with multiple escape holes, they must be greater than 2mm in diameter. Models with smaller holes may be rejected. Positioning escape holes at the opposite ends of a model (one on top, one on the bottom) will help the finishing process.
