About Silver 3D Printing

Sterling Silver (92.5% silver) is a high quality silver alloy commonly used in jewelry and other skin-safe applications. With several finishing options and the ability to showcase intricate details, 3D printing Silver offers a professional, finished look and feel. 3D printed Silver will tarnish over time, but can be polished to achieve a like-new surface. This material is a softer metal that will be more malleable with thin features.

Color & Finishes

Natural
3D print Silver with light polishing for a somewhat rough surface with a matte finish.
Polished
3D print Silver for a hand-polished finish, and a smooth, shiny surface.
Fine-Detail Polished
Extensive polishing of 3D printed Silver will reach intricate details, achieving a very shiny surface. Extra polishing will remove more material so some details may be lost in the process.
Antique
Recessed details are blackened to achieve a steampunk look.

Design Guidelines

Bounding Box

Bounding Box Max
89 × 89 × 100 mm
75 × 75 × 40 mm for Interlocking Parts

Bounding Box Min
2.4 × 2.4 × 0.6 mm

The bounding box is a 3D imaginary outline of a box that encloses the smallest area occupied by your model. Your model must be within the minimum and maximum bounding box sizes. If the size of the model is close to the maximum bounding box, then the printing orientation will be restricted.

Walls

Supported Wall Thickness Min
0.6 mm (Natural)
0.8 mm (Polished, Fine Detail Polished, Antique)
Unsupported Wall Thickness Min
0.6 mm (Natural)
0.8 mm (Polished, Fine Detail Polished, Antique)
A supported wall is connected at least on two sides of the wall, while an unsupported wall is connected only on one side of the wall. Walls that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wall geometry of the model. Please consider the size of your model and reinforce the walls or add support structures as needed as minimum guidelines will not always be adequate for large models.

Wires

Supported Wires Min
0.8 mm (Natural, Polished, Fine Detail Polished, Antique)
1.5 mm (for Interlocking Parts)
Unsupported Wires Min
1.0 mm (Natural, Polished, Fine Detail Polished, Antique)
1.5 mm (for Interlocking Parts)
A wire is a circular, rectangular or even triangular feature that is thinner in its unconnected directions than its length. A supported wire is connected at least on two sides of the model, while an unsupported wire is connected on one side of the model. Wires that do not meet the minimum requirements may not survive printing and cleaning processes. Additionally, models may still be rejected based on the wire geometry of the model. Please consider the size of your model and reinforce the wires or add support structures as needed as minimum guidelines will not always be adequate for large models.

Details

Details Min Embossed
0.3 mm high & wide (Natural, Polished, Antique)
0.4 mm high & wide (Fine Detail Polished)
Details Min Engraved
0.3 mm high & wide (Natural, Polished, Antique)
0.35 mm high & wide (Fine Detail Polished)
For text, the ratio between width and depth, should be 1:1 and sans-serif fonts are preferred for line weight consistency.

Escape Holes

Single Escape Hole Diameter (Min)
4.0 mm
Multiple Escape Hole Diameter (Min)
2.0 mm
Escape holes are necessary to empty the support material of a hollow model. Two escape holes at the opposite ends of the model is optimal for the support removal process. Please consider the size of your model and make the escape holes bigger or add more escape holes as needed as minimum guidelines will not always be adequate for large models.
A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.

Clearance

Min
0.3 mm
1.0 mm (for Interlocking Parts)
Clearance is the space between two individual parts in a model. If the space among the individual parts do not meet the minimum clearance, then parts can fuse together or can be difficult to clean. This is important for movable pieces like hinges, gears, etc.

Interlocking & Enclosed Parts

Interlocking
Yes, up to six for Natural and Polished finishes. Interlocking parts are not supported for Antique and Fine Detail Polished finishes such as 3D printed Silver.

Enclosed
No

Parts in File

Max
Up to two identical 3D printed silver parts (like earrings or cufflinks) may be uploaded in the same model file. We cannot accept multiple, unique, non-interlocking parts ordered in the same model file; there should be one file for each unique part. Also, we cannot accept sprued parts as this creates problems during the casting process.

Accuracy

Accuracy Natural: When you 3D print Silver, the model may shrink about 0.15 mm plus 1.5% after casting and finishing. For rings the inner diameter will be 0.125 - 0.15 mm smaller than your design. On average, when you 3D print Silver, the model shrinks about 1.5% after casting and finishing. Scaling up your model by 1% will make your design closer to your desired size. Polished, Fine Detail Polished and Antique: Your model may shrink about 0.25 mm plus 2.5% after casting and finishing. For rings the inner diameter is accurate within +/- 0.1 to 0.15mm. On average, the model shrinks about 2.5% after casting and finishing. We do our best to polish the internal diameter to match your model file.
