DMLS Bronze(Cu90Sn10) material is a popular choice in the jewelry and art sectors due to its excellent polishability and visual similarity to precious metals.

- Model volume: The volume of your model is used to calculate the material cost (mm³)
- The box around your model: An imaginary box around your model determines how much space your design will take up in the printer (X * Y * Z = mm³)

For Bronze, we charge a minimum price per ordered piece. Unlike the startup cost (which is applied to most materials), this cost vanishes when the price is higher than the minimum price.
Raw bronze is a high-detail metal with a deep red color similar to rose gold. It has a subtle marbling effect, and the silvery highlights give each piece their own unique character.
Polished bronze goes through extensive hand polishing to give it a smooth, glossy finish. It is great for miniatures, precious objects, and shiny, modern jewelry. Raw Bronze has a rustic matte look with rough surfaces. It is great for antique-looking objects, vintage and steampunk jewelry, functional parts, and jewelry prototypes.
Some detail is lost during polishing and plating
Polishing and plating give this material a beautiful finish, but can have an impact on fine details. During the polishing step, fine or sharp-edged details may be polished down or even broken off. During plating, intricate engravings or holes may be filled in partially or completely. Keep this in mind when you're designing fine details.
Internal detail can not be polished
We can only polish well-reachable surfaces, so tight internal spaces may remain unpolished and show slightly uneven plating.

| Min Supported Wall Thickness|
A supported wall is one connected to other walls on two or more sides.
| Min Unsupported Wall Thickness|
An unsupported wall is one connected to other walls on less than two sides.
| Min Supported Wires|
A wire is a feature whose length is greater than five times its width. A supported wire is connected to walls on both sides.
| Min Unsupported Wires|
A wire is a feature whose length is greater than five times its width. An unsupported wire is connected to walls on less than two sides.
| Min Embossed Detail|
A detail is a feature whose length is less than twice its width.
The minimum detail is determined by the printer's resolution.When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details that are too small can also be smoothed over in the polishing process.
To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.
| Min Engraved Detail|
A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.
| Min Clearance|
Clearance is the space between any two parts, walls or wires.
To ensure a successful product, make the clearance between parts, walls, and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.
| Min Escape Holes|
Escape holes allow unbuilt material inside hollow products to be removed.
Normally you don't need to consider this, our technician will add escape holes before printing.
When products contain hollow cavities, they are often filled with powder/liquid even after they are removed from the build tray. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it.
| Interlocking/moving or enclosed parts?|
Sometimes the interlocking/moving parts can't be printed, since the supports inside the cross section can't be removed.
| Require Support Material?|
Because each layer needs to build off the last, for some material, angles of more than 45 degrees generally require supports to be printed along with the design. Supports are not inherently detrimental for your design, but they do add complexity to the printing process and lead to less smooth finish on overhanging parts.

Material Spec Sheet
DMLS Bronze(Cu90Sn10) is 3D printed using SLM/DMLS (Selective Laser Melting) technology.
Selective Laser Melting creates objects from thin layers of powdered material by selectively melting it using a high power laser. The process takes place in a low oxygen environment in order to reduce thermal stresses and to prevent warping.
Industrial metals are best used for high-tech, low-volume use cases from prototyping to creating end-use parts. Metal 3D prints are comparable to traditionally manufactured parts in terms of chemical composition, mechanical properties (static and fatigue) as well as microstructure.
Once the printing is done, the extra powder that was not bound, and is not part of your design, is removed. Your part is now solid metal, and after the flutes are manually removed, it is tumbled and polished to produce a smooth finish.
