TECHNOLOGY
3D Printed Sterling Silver is made using a three-step process.
We 3D-print your model using the 3D Wax printer.
We use a lost-wax casting process to smelt your model
We apply a polishing to the molt part.
Please have a look on the wikipedia page to know more about wax casting process:
3 types of finishing for Sterling Silver Sterling are offered:
Rough: your model is cleaned by using sandblast, giving a rough surface
Polished: your model is mechanically polished. The surface is smooth and slightly shinny, it may show print lines.
Mirror polished: your model is highly hand polished in order to look very shinny, like a mirror. The surface is perfectly smooth and all print lines will disappear.
Design guidelines:
Maximum size : 60 x 80 x 80 mm
Minimum size : 2.4 x 2.4 x 0.8 mm
Minimum possible wall thickness: 0.8 mm
For parts under stress like ring shaft, pendant loops or wire, minimum thickness is 1 mm
Minimum for engraving details: 0.4 mm
Minimum for embossing details: 0.4 mm
Accuracy: 0.025 mm
Chain mail and design with part included into another volume – “ball in a ball” cannot be made with this process. For earrings and cufflinks, you can add 2 parts in the same file
Avoid deep engravings or high embossed details
Engraved details that are too deep will cause issues when casting. Embossed details that are too tall are more likely to chip and break during production (unless the detail meets the minimum wall requirements).
Wires must be at least 1 mm thick
Wire frame models are difficult to print and are also fragile in silver. It might also snap in the manufacturing process. For security we recommend to have 1 mm thickness.
Ring bands should be 1mm thick
Ring band (the part that goes around the finger) needs to be 1mm thick to avoid deformation when wearing. Since silver is a weaker or more flexible material, ring bands that are too thin may deform or even break.
Internal detail can not be polished
Mechanical or hand polish process can only polish well-reachable surfaces, so tight internal spaces will remain unpolished.
Every parts will be marked with a small hallmark
In accordance with French regulations, we will apply an hallmark on the external surface of your part. This mark will be very small and we will try to make it as discreet as possible.
Special care advices for polished silver
The surface of polished silver is very soft and can be scratched when it is weared,. Please keep your silver models separatly from your other jewels, for instance in a separate box. We recommend the use of a silver polishing kit to clean and keep a shinny surface.
