About Steel

Steel is an affordable and strong metal that is well-suited for consumer products both small and large with an industrial look and feel. It’s printed using a binder jetting process and is later infused with bronze, creating a material that is 60% steel and 40% bronze and can range in color from a silver gray to reddish bronze. It is strong enough for metal parts like bottle openers and dice, but is not recommended for industrial load bearing applications.

Color & Finishes

Bronze
This finish gives the material a brown antique bronze look
Gold
A thin layer of 24K gold plating that will wear with handling
Nickel
A thin layer of nickel plating providing a shiny silver gray color that will wear with handling
Bronzed-Silver
A metallic silvery color with a bronze tint
Black
The black finish gives the material a dark gray to black look
Matte
Unpolished for a rough surface and matte finish.
Polished
Parts are polished until shiny and smooth. Note: Products larger than 150 x 150 x 150 mm and products with particularly thin features or details will undergo bead blasting instead of the regular polishing process in order to avoid breakage. This may lead to a rougher and less consistent finish than usual.

Design Guidelines

Bounding Box

Bounding Box Max
762 脳 393 脳 393 mm (Bronzed-Silver, Bronze, Black)
178 脳 178 脳 178 mm (Gold, Nickel)
152 脳 152 脳 76 (Polished models)
178 脳 178 脳 178 (Plated models)

Bounding Box Min
6 脳 6 脳 3 mm

The bounding box is a 劲爆体育在线直播 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
Model鈥檚 Longest Dimension:
3 to 75 mm = 1.0 mm
75 to 150 mm = 1.5 mm
150 to 200 mm = 2.0 mm
200 to 300 mm = 3.0 mm
Unsupported Wall Thickness Min
Model鈥檚 Longest Dimension:
3 to 75 mm = 1.0 mm
75 to 150 mm = 1.5 mm
150 to 200 mm = 2.0 mm
200 to 300 mm = 3.0 mm
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
Model鈥檚 Longest Dimension:
3 to 75 mm = 1.0 mm
75 to 150 mm = 1.5 mm
150 to 200 mm = 2.0 mm
200 to 300 mm = 3.0 mm
Unsupported Wires Min
Model鈥檚 Longest Dimension:
3 to 75 mm = 1.0 mm
75 to 150 mm = 1.5 mm
150 to 200 mm = 2.0 mm
200 to 300 mm = 3.0 mm
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
1.0 mm high & wide
Details Min Engraved
1.0 mm high & wide
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
3.0 mm
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.

Sprues

We cannot print Steel parts with sprues. Any part with sprues will be rejected. Since sprues are inherently thin by design, Bronze will not be able to be infiltrated between parts that are sprued and the model will fail in production.

Sprues are wires that keep two or more parts together. Parts should be connected with a minimum of two sprues each. Please consider the size of your sprues and increase them as needed as minimum guidelines will not always be adequate for large models. If the sprues are within the guidelines and are broken, but there is no damage to your model, we will still ship them as is.

Accuracy

Accuracy 卤5% The bronze infiltration of each steel part makes this material less dimensionally accurate than other Shapeways materials. Shrinkage is more prevalent, especially on small holes and inner diameters. Accuracy and tolerance can vary greatly depending on the model, and are hard to predict because they are so geometry specific. A 5% deviation on a ring is around 1 US ring size. So if you order a size 6, the deviation could cause the actual print to be a size 5 or 7.
For example: a product with dimensions of 50 x 50 x 100 mm can be 0.05*100 mm = 5 mm bigger or smaller in any direction.
