About Brass – 3D Printing Material
3D Brass printing is popular for use in applications like jewelry, accessories, home decor, and miniatures. A Copper alloy containing 15% Zinc, 5% Tin, and 80% Copper, this Brass 3D printing material showcases intricate details and offers a professional, finished look and feel. 3D printing with Brass may include dealing with tarnish over time, but these materials can easily be polished to achieve a like-new surface.
Color & Finishes
Natural
Natural 3D Brass printing offers a light polish, resulting in a somewhat rough surface with a matte finish.

Polished
Polished 3D Brass printing is hand-polished for a smooth, shiny surface. (Internal detail can not be polished, well-reachable surfaces will be polished therefore tight internal spaces may remain unpolished.)

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)
Wires
Supported Wires Min
0.8 mm 1.5 mm for Interlocking Parts
Unsupported Wires Min
1.0 mm 1.5 mm for Interlocking Parts
Details

Escape Holes
Single Escape Hole Diameter (Min)
4.0 mm
Multiple Escape Hole Diameter (Min)
2.0 mm
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
Interlocking & Enclosed Parts
Interlocking
Yes
Enclosed
Yes
Parts in File
Max
Up to two identical parts (like earrings or cufflinks) may be uploaded in the same model file during 3D Brass printing. We cannot accept multiple, unique, non-interlocking parts ordered in the same model file.
Accuracy
Accuracy
3D models may shrink about 0.25 mm plus 2.5% after casting and finishing as part of the 3D Brass printing process. 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 during the 3D Brass printing process.
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.
