PA11 CF (Carbon Fiber)

Daniel Aarts

Technical Director at Innoseal Europe

Sinterit’s Lisa X has allowed us to reduce lead-times and create better solutions — faster, helping us satisfy our customers. We have looked at other 3D printing methods, and other brands, but ultimately decided on SLS and chose Sinterit for their communication, and open material possibility. Something we couldn’t find in other suppliers of affordable entry level SLS printers.

Innoseal case study with Sinterit LISA X

Alberto Parolin

R&D Team Leader in BNP

Getting Lisa X solved a lot of our problems. It has a big enough printing area, so we almost always can print big components in one part. It wouldn’t be possible with competitive SLS 3D printing solutions.

Philippe Bendel

Additive Manufacturing Development Leader – Somfy

The main reason Somfy reached out for the SLS technology from Sinterit was productivity. Printing many pieces in one batch was a game-changer

FAQ

How should I store the printing powder?

– Store the powder at room conditions ( ~23°C and 50% humidity – the lower humidity the better)
– Always store the material in a sealed dry box/container.
– Do not leave the container open.
– Clean the machine directly after printing and store the material immediately after removing the print cake.
– Do not let the powder stay in the printer for more than a couple hours.
– Put a few silicone absorbers in the container (but don’t add them to the printer)

What is the difference between “Fresh” powder and “Starter powder”?

Starter powder is basically a print-ready powder.

In Sinterit we distinguish three powder conditions: print-ready, used, and fresh.

Used is a type of powder that you get after the printing, present in overflow bin or remaining after printout cleaning.
Fresh is a type of powder that is being used for refreshing the powder. After mixing this powder with used powder you will receive print-ready.
Print-ready is a type of powder that you can simply pour into the printer and start printing.

Although printing using Fresh is possible it’s not economically optimal therefore Sinterit printers are optimized for using a refreshed (print-ready) powder.

Why do I need an ATEX vacuum cleaner to clean powder?

SLS polyamide powder used for 3D printing is considered particulate matter because of its size. Polyamide powder particles are generally 40 micrometers or smaller. If vacuumed in an ordinary vacuum cleaner, the powder could cause an explosion.

Such materials are subject to labor regulations on air quality and occupational safety. The procedures call for appropriate maintenance of powder at work. Only certified industrial vacuum cleaners should be used to clean such materials. More information about the ATEX Vacuum cleaner can be found here.

What is PA11 Carbon Fiber and what makes it special?

PA11 Carbon Fiber is a bio-derived composite powder based on Polyamide 11 and enhanced with carbon fibers. It offers superior mechanical strength, thermal resistance, and stiffness, making it one of the strongest SLS powders available.

What applications is it best suited for?

This material is ideal for high-performance automotive parts, motorsport components, aerospace models, prosthetics, maintenance tools, and mechanical parts in extreme environments.

Which printers is this material compatible with?

It is compatible with the Sinterit Lisa X and Lisa Pro printers.

Does it require nitrogen during the printing process?

Yes, nitrogen is required to print with PA11 Carbon Fiber.

What is the refresh ratio of this powder?

The refresh ratio is 40%, meaning 40% of the powder in a new job must be fresh.

What are the standout mechanical properties?

PA11 Carbon Fiber offers a tensile strength of up to 65.9 MPa, flexural strength up to 87.3 MPa, and impact resistance up to 73.9 kJ/m² (Charpy unnotched).

How thermally resistant is it?

It features a melting point of 197 °C and a heat deflection temperature (HDT B) of up to 190 °C in the X direction—one of the highest in Sinterit’s powder range.

What is the surface finish like?

PA11 Carbon Fiber provides good surface quality along with high stiffness, dimensional stability, and chemical resistance.

What color are the printed parts?

The powder and printed parts are black, which gives a professional, high-performance appearance.

Is this material sustainable?

Yes, it is bio-based and derived from castor oil, making it an environmentally conscious choice for high-end engineering applications.
