Ultrasint® PA11 ESD Material Guide

What is Ultrasint® PA11 ESD?

Ultrasint® PA11 ESD is a bio-derived powder material with electrostatic discharging properties for increased process safety in advanced applications. With its interesting mechanical properties, this material offers new possibilities for a wide range of new applications, especially for the electronics sector. 

Your parts will be 3D printed using sustainable powder, derived from castor oil. Parts 3D printed with Ultrasint® PA11 ESD discharge all unwanted electrostatic charges from sensitive components and systems, it also reduces the risk of electrostatically induced failures and damages. If you are prototyping or producing a project where electrostatic discharging safety is critical, this PA11 material will be the perfect choice.  

Ultrasint® PA11 ESD is printed using Selective Laser Sintering. Please keep in mind that you will have to respect specific design guidelines to avoid any problem during the additive manufacturing process. Be sure to check the material design guidelines while creating your 3D file and before you send it for 3D printing.

What are the possible applications for this material?

Thanks to this PA 11 material, you can easily manufacture your ESD-safe prototypes and end-use parts. Indeed, the surface resistivity of Ultrasint® PA11 ESD is lower than traditional electrostatic dissipating materials. 

Electrical propertiesTest Method Typical Values (X-direction)Typical Values(Z-direction)

This material also presents great mechanical and thermal characteristics.

  • Electronic Housing

Ultrasint® PA11 ESD allows you to handle your electronic components with a higher level of safety, as the material does not accumulate static electricity and can come in contact with electronic components without running the risk of damaging them.

  • Jigs and fixture for electronics

Ultrasint® PA11 ESD is the optimal material for the rapid construction of durable jigs and fixtures for the electronics industry. 

  • Tooling

Start to optimize your tooling process and the creation of machine parts by using 3D printing. Ultrasint® PA11 ESD has some interesting mechanical properties such as high tensile strength and elasticity, which could help you create efficient tools. 

Pricing​

The printing price of your design is calculated automatically the moment it is uploaded. As you modify your object (changing material, finishing, size, using our hollowing feature, etc.) you will note that the price changes automatically. The pricing is based on a series of factors, including total volume, object size, and bounding box – to name a few.

The estimated shipping time is also calculated automatically as the object is uploaded and each time you make a modification on it. Delivery time should be added to processing time.

How does Selective Laser Sintering work?

Sculpteo uses a layer by layer process called Selective Laser Sintering (SLS) to manufacture Ultrasint® PA11 ESD parts.

The Selective Laser Sintering technology uses a highly specific laser that sinters thin layers of powder together one layer at a time. After each round of lasering, the printing bed is lowered and another layer of powder is evenly swept across the top for another round of sintering. This 3D printing process continues until the part is fully printed according to the 3D file.

Maximum size

150x 200x 250 mm

The maximum size of your models are limited by the physical size of our 3D printers – nothing can be printed larger than the printer bed.

Due to the printing process, your objects will have upskin and downskin. Upskin is a little concave, whereas downskin will show slight convex. Upskin will appear on the top of your object, downskin at the bottom. This is important to consider when you set the orientation of your 3D model. If the upskin and downskin will affect your design, set the orientation beforehand and we will honor it, if you are not sure, our technicians will choose the best one.

Ratio Depth / width1/1 
A detail’s minimum precision is mainly determined by the resolution of our 3D printers. However, during the cleaning process, a fine layer of detail can also be lost. In order for a detail and text to be visible we recommend following our recommended sizes at the very least.It’s possible that particularly fine embossings and engravings will not be visible, as the carving could get filled with excess powder that is later unable to be cleaned out. If an embossing or engraving is an essential part of your design we recommend making them as deep as possible. To ensure a better powder removal (thus a better detail visibility), the width of your details must be at least as big as depth.
Enclosed parts ?Yes
Interlocking parts ?Yes


Our material has the ability to print the most complex designs of our materials . An example of a complex design is a volume enclosed within another volume, like a chain or a ball joint connection. Our printers have the ability to print a fully interlocked chain, with no support structures to remove.

Minimum spacing between fixed walls0.5 mm
Minimum clearance between parts0.5 mm


For a successful 3D print a minimum clearance between objects is required to allow excess material to be sand blown out. If this space is not left within the design, the object will be a solid. This is particularly important for articulated objects – as the space left between the walls will define the object’s ability to move.


Do not forget

Clearance should be at least 0.5 mm, however that is the minimum for small objects. Larger objects require more space between their parts. This is due to the HP printing process. Our printer beds are heated during the process, and larger objects are heated for longer periods. A small space between large objects runs the risk of melting together as it remains under heat for a long period of time. In some other cases, holes should be added to allow us to drain for the excess powder material within the clearance.


Hollowing ?  Yes: 5mm

Our online hollowing optimization tool has the ability to greatly reduce the price and the weight of a print by reducing the amount of material used.

Using the tool requires adding two holes to your model, which will serve as the drain for the excess powder material within the object. The minimum size of these holes is determined by our website. Otherwise, it is possible to hollow your object manually in your 3D modeling software.
