What is SLS?
Selective Laser Sintering [SLS]

Selective laser sintering (SLS) uses a laser as the power source to sinter powdered material, aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.

About Nylon 11 [SLS]

PA11 is a biocompatible nylon material that is durable and flexible, making it optimal for use in exterior medical applications. Our PA11 is printed using SLS technology, which uses a laser to sinter nylon powder into plastic layer by layer. It is tensile, durable, and impact-resistant with high elongation at break. PA11 is offered in a natural white finish.

Walls

Supported Wall Thickness Min
0.5 mm
Unsupported Wall Thickness Min
0.5 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
0.7 mm
Unsupported Wires Min
1.0 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

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)
3.00 (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
1.0 (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

2 mm thick, attached in at least 2 places per part

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.

Design Guidelines

Bounding Box
Bounding Box Max
300 × 300 × 600 mm
Bounding Box Min
0.7 × 0.7 × 0.7 mm , X + Y + Z ≥ 7.5 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.

Accuracy

Accuracy  0.15 mm + 0.5%

For example: a product with dimensions of 50 x 50 x 100 mm can be 0.3 mm bigger or smaller in any direction.

Material info
About Nylon 12 [SLS]

Versatile Plastic fis a durable nylon plastic that can be used for a wide range of applications, both for prototyping and for end products. Printed using Selective Laser Sintering (SLS), when thin, it’s flexible enough for hinges and springs and when thick, it’s strong enough for structural components. Try the Premium finish for a higher quality look and feel.
