Brass – 3D Printing Material
Brass – 3D Printing Material
Material Info
About
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. Internal detail can not be polished, well-reachable surfaces will be polished therefore tight internal spaces may remain unpolished. More information about this material can be found in our Help Center.
Color & Finishes
Natural 3D Brass printing offers a light polish, resulting in a somewhat rough surface with a matte finish.
Polished 3D Brass printing is hand-polished for a smooth, shiny surface.
Technology
- Wax Casting
Description
Design Guidelines
Bounding Box
Maximum Bounding Box
89 × 89 × 100 mm
75 × 75 × 40 mm (Interlocking Parts)
Minimum Bounding Box
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
0.8 mm (Polished)
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
0.8 mm
1.5 mm (Interlocking Parts)
1.0 mm
1.5 mm (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
0.35 mm high & wide (Natural)
0.4 mm high & wide (Polished)
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
4.0 mm
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.
Clearance
0.3 mm
1.0 mm (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
Enclosed
Yes
Parts in File
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
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.
