PA6 FR Material Guide
What is PA6 FR?
PA6 FR is an Halogen-Free Flame-Retardant PA6 powder for advanced applications. This Ultrasint® PA6 FR is an engineering polymer powder made with an innovative formula, containing a flame-retardant (FR) additive. With its halogen-free formulation based on PA6, this 3D printing material is unique, offering new possibilities for a wide-range of new applications from the electronics to public transportation sectors.
3D printed PA6 FR parts are black and manufactured using Selective Laser Sintering (SLS) technology. 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?
PA6 FR combines excellent mechanical and thermal performance with flammability requirements. Indeed, the main feature of Ultrasint® PA6 FR is its broad spectrum of flammability ratings relevant in different application fields.
It is relevant to use this 3D printing material for flammability-sensitive application fields such as electronics, aerospace and public transportation.
For aerospace applications Smoke Density and Smoke Toxicity (FST) tests have been successfully passed. It is offering the possibility to 3D print air ducts, for example. Jigs and fixtures for cables and pipes can be 3D printed.
V2 rating (UL 94V)
PA6 FR can also be used for buses and transport (ECE-R 118 App.7 test) for use in public buses successfully passed. PA6 FR is the perfect 3D printing material to use for flammability-sensitive application fields.
- High temperature
The formula of this innovative material is containing a flame-retardant (FR) additive. PA6 FR is a flame retardant material also offering impressive mechanical properties, offering new possibilities for a wide-range of applications
- Electronic casing
This high performance material can be used for electronics projects, its has a UL 94 V-2 rating starting at 0.8 mm, and it has a Glow Wire Flammability Index (GWFI) up to 960 °C. PA6 FR is the perfect material to manufacture switchboard parts and any other electronic components.
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.
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 PA6 FR 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.
360 x 360 x 420 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.

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 walls||0.5 mm|
|Minimum clearance between parts||0.5 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.
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.
