PA6 MF Material Guide

What is PA6 MF?

PA6 MF is built on the chemical base of reinforced PA6; it boasts extremely high rigidity, media tightness, and enhanced thermal distortion performance. This plastic material is the perfect choice for any advanced technical applications where properties of mechanically reinforced thermoplastics are required.

Compared to standard PA6, mechanically reinforced Ultrasint® PA6 MF combines superior thermal resistance with high isotropic rigidity thanks to in-particle reinforcement technology.

PA6 MF is 3D printed using Selective Laser Sintering, and parts in the raw state are black. 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 its exceptionally high strength and rigidity, PA6 MF is perfectly suited for production as well as for functional prototypes.

With the adapted and optimized design, parts printed using PA6 MF can have the same parameters than traditionally injection molded parts, and go even further in terms of performance.

For tooling equipment, molds or any multi-purpose industrial goods, this PA6 MF 3D printing material can fit the needs of your project.

  • Extremly high strength and rigidity 

Tensile Modulus: 3300 MPa

This material is highly resistant and perfect to create functional parts for engine bay parts and many other parts in the transportation sector. PA6 is strong enough to hold the whole engine assembly and handle all heat, vibration and static loads. 

  • High temperature

HDT/B: 207°

The melting point of PA6 MF is 220 °C, making it a 3D printing material particularly interesting for projects where heat resistant parts are required.

  • Airtight – Watertight – Chemical resistant

PA6 MF is also well-suited to media flow and storage parts (i.e. oil). Thanks to 3D printing and the media tightness of this PA6 MF material, you can create made-to-measure chemical resistant parts such as 3D printed reservoirs. 

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 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 MF 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

   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.

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.
