Since the resolution of the wax printing process is so high, make sure that you create your model and export your file with enough definition so you don’t see the triangles.
Be careful when having large areas of your model connected supported by thin rods. Compare it to a big head resting on a thin neck. Ask yourself if the rods are strong enough to ‘carry’ the weight of the larger area. Also, internal structures are possible to print, but removing support structures, cleaning them and casting them can be difficult or eve impossible. If you have doubts about whether your model is feasible, please contact us.
Bronze allows you to print hollow models. However, keep in mind that you need to incorporate holes or slots so we can get rid of the unprinted wax resin and make sure that the casting plaster is sufficiently supported. Without this, your model cannot be cast properly. Make as many holes or slots as possible (at least two holes or slots for each side), each with a minimum diameter of 1.5 mm.
The smallest features in your design should be at least 0.35 mm in diameter and 0.4 mm in height and attached to a solid surface. Details this small are suitable for delicate projects such as micro pavé settings.
Because Bronze is not a very strong material, longer features such as rods or prongs (in mesh-like structures) should be at least 0.8 mm in diameter. Otherwise, they might break during casting or even when you wear the piece.
In order to polish, we have to be able to reach the surfaces. As a rule, we can't file, sand or polish cavities and small sharp edges will be rounded off. Also, as you can imagine, complex internal, mesh-like structures are also impossible to reach.
Nested objects (objects floating within another object), hinged parts, and interlinking parts, such as chains, cannot be made with lost wax casting. The reason is that support structures have to be removed before being cast in Bronze.
For embossing or engraving details such as text, we advise you to keep a maximum height/depth-to-width ratio of 1:1. Also, keep in mind the minimum wall thickness of 0.35 mm.
