PA2210 FR Material Guide

What is PA2210 Flame Retardant?

PA2210 Flame Retardant is a highly performant material, similar to the widely used Nylon PA12, except that it has Flame Retardant properties.

While 3D printing offers endless possibilities, it is crucial to consider safety measures, especially when it comes to fire hazards. This is where the use of flame retardant materials like PA2210 Flame Retardant becomes paramount. Let’s see what are the benefits of using flame retardant materials in your applications.

One of the primary advantages of using flame retardant materials in 3D printing is the significantly enhanced safety they provide. Flame retardant materials are specifically designed to inhibit or delay the spread of fire if a fire incident occurs. This crucial feature reduces the risk of accidents, potential property damage, and even loss of life. By using flame retardant materials, users can prioritize safety and ensure a secure working environment.

What is PA2210 Flame Retardant used for?

PA2210 Flame Retardant is the perfect material in applications where important technical requirements such as resistance to flammability are necessary.

One of the most interesting aspects of this material is its halogen-free composition, meaning that, while if it burns, it will not release toxic fumes.

Furthermore, PA2210 Flame Retardant is Blue Card certified with UL-94 V-0 for wall thickness above 3mm. This material also complies with IEC 60695-11-10, Fire Hazard Testing-Part 11-10: Test Flames-50 W Horizontal and Vertical Flame Test Methods.

It is especially suitable for applications in:

  • Construction: Where objects such as flame retardant electric panels, can be really useful.
  • Electronics: To prevent overheating and reduce risks of fire hazards.
  • Transportation: In parts used in trains, cars or planes, to reduce risks of fire hazards.

Warning : If your model has a wall thickness below 3mm, the flammability will be rated as “HB” (please refer to the Technical Datasheet in the related section, for further details about the flammability).

While this information serves as a guide to the customer, it is ultimately the end customer’s responsibility to verify, through testing, compliance of the final part or its assembly with the standard.


The printing price of your design is calculated automatically the moment it is uploaded. As you modify your object (changing material, finishing, size, using batch control or 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.

Keep in mind that adding finishing will extend the processing time. 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.

What is the 3D printing process for PA2210 Flame Retardant?

PA2210 FR is printed using Selective Laser Sintering. The SLS printing process uses a highly specific laser that sinters thin layers of our nylon 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 process is repeated until the object is completed.

What are the finishing options for our PA2210 Flame Retardant?

Raw: your part will be sandblasted but unpolished, the surface remains somewhat rough.

We only offer PA2210 Flame Retardant parts raw, since other finishing options might alter the material’s characteristics.

Disclaimer: While parts with a minimum wall thickness of 0.8 mm are printable, we kindly remind you that a minimum wall thickness of 3 mm is required in order to be compliant with the materials Blue Card and UL-94 V-0 certifications.

The walls of your design must adhere to a minimum thickness of 0.8 mm in order to guarantee the structure will not break. If the walls of your model are less than 0.8 mm, you can add a support structure to maintain stability.

A stemmed element is a design aspect which is at least twice as long as it is thick. For unsupported and stemmed elements or parts of the design with a particular design constraint, it is also important to respect a minimum thickness of 1 mm in order to guarantee the object will not break.


Icon to show that you can ad a support structure to maintain stability

Add a support structure to maintain stability. For example, if you are modelling a bust of a person, you can attach thin aspects of the design like the ears in more places around the model’s head. Doing that will avoid cantilevered and easily breakable elements in the final print.

With a 0.8 wall thickness, your design will be slightly flexible. To obtain more rigidity, we advise a 2mm wall thickness.

Good to know

Thin walls supporting large, heavy models can warp under the weight of itself.

Sculpteo offers an online solidity check tool which highlights parts of the print that may be too thin for a print. From there you are able to tweak your design in order to create an object that is an appropriate thickness. To use it, you just need to upload your 3D file, select your material and click on “Verification” tab.

It is also important to keep in mind that the object is to be printed into real life. Thus if a thin aspect is supporting something that is too heavy for it, it may break – even though it is possible within the physics provided by your 3D modeling software. We recommend adding a bit of thickness to the places that will get a lot of handling, or that support the most weight.

Do not forget

Icon to keep in mind that solidity check tool don't detect physical aberrations

Keep in mind that our solidity check tool does not detect physical aberrations such as floating parts, unstable position, parts supporting too much weight relative to their thickness, etc. Particular care must be given to the geometry of your design and the most stressed parts must be thickened.

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.

Enclosed parts ?Yes
Interlocking parts ?Yes

Our PA2210 FR material has the ability to print some of the most complex designs of our materials thanks to Selective Laser Sintering technology. An example of a complex design is a volume enclosed within another volume, like a chain or maraca. 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 SLS 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.

Assembly ?Yes
Minimum space0.5 mm

PA details

Objects printed in polyamide can be printed to be assembled. As long as a width of at least 0.5 mm is left between the different parts of the object.

Hollowing ?Yes

Our online hollowing optimization tool has the ability to greatly reduce the price 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.

Files with Multiple Objects ?No
