About Bronze 3D Printing

Bronze is a copper-tin alloy featuring a deep red color, similar to rose gold. Jewelry, accessories, and home decor are all popular applications for use with Bronze 3D printing. This metal material exhibits a subtle marbling effect with silvery highlights, giving each piece unique character with a vintage look. Composed of 10% Tin and 90% Copper, Bronze 3D printing materials are capable of showcasing intricate details, and offering a professional, finished look and feel. This material will tarnish over time, but can be polished back to achieve a like-new surface.

Color & Finishes

Natural Bronze 3D Printing
Light polishing to achieve a somewhat rough surface with a matte finish.
Polished Bronze 3D Printing
Hand-polished to achieve a smooth, shiny surface. (Internal detail can not be polished, well-reachable surfaces will be polished therefore tight internal spaces may remain unpolished.)

Technology

  • Wax Casting

Description

Material Highlights
High-quality, shiny finishing, intricate detail and great value are all characteristics of Bronze 3D printing.
Handling and Care
Like all Bronze 3D printing materials, Polished and Natural finishes will tarnish over time and may require polishing or cleaning.

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)
Unsupported Wall Thickness Min
0.6 mm (Natural)
0.8 mm (Polished)
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
0.35 mm high & wide (Natural)
0.4 mm high & wide (Polished)
Details Min Engraved
0.3 mm high & wide (Natural)
0.35 mm high & wide (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 Bronze 3D printing.

Enclosed
No

Parts in File

Max
Up to two identical parts (like earrings or cufflinks) may be uploaded in the same model file for Bronze 3D printing. We cannot accept multiple, unique, non-interlocking parts ordered in the same model file; there should be one file for each unique part for successful Bronze 3D printing.

Accuracy

Accuracy Your Bronze 3D printing 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 Bronze 3D printing model shrinks about 2.5% after casting and finishing. We do our best to polish the internal diameter to match your bronze 3D printing model file.
For example: A product with dimensions of 50 x 50 x 100 mm can be 0.25 mm + 0.025*100 mm = 0.5 mm smaller in any direction.
