Polymaker Fiberon ASA-CF08 1.75mm Filament 500gFiberon is polymakers family of fibre reinforced composite filaments developed to provide outstanding mechanical performance for a range of engineering applications. Fiberon ASA CF08 combines the UV and weather resistance of ASA with 8% carbon fibre by weight, delivering high rigidity, dimensional stability, and a professional matte finish. In combination with high speed printing up to 350 mm s and heat resistance up to 103 C (HDT 0. 45 MPa), ASA CF08
Fiberon™ is polymakers family of fibre-reinforced composite filaments developed to provide outstanding mechanical performance for a range of engineering applications.
Fiberon™ ASA-CF08 combines the UV and weather resistance of ASA with 8% carbon fibre by weight, delivering high rigidity, dimensional stability, and a professional matte finish. In combination with high-speed printing up to 350 mm/s and heat resistance up to 103 °C (HDT 0.45 MPa), ASA-CF08 delivers a reliable choice for functional prototypes, outdoor components, and end-use parts in automotive, industrial, and consumer applications.
Features
- Outstanding weather & UV resistance - With excellent weather resistance (UV, water and heat) Fiberon™ ASA-CF08 is the ideal choice for printing high rigidity components that must survive in the harsh outdoors. Most plastics tend to become brittle and their colour turns yellow when exposed to UV radiation or sunshine but with Fiberon™ ASA-CF08 the appearance and mechanical properties of your 3D prints are not influenced negatively by UV light.
- Outstanding Stiffness & Dimensional Stability - Polymakers 8% carbon fibre reinforcement significantly improves stiffness, tensile modulus and dimensional stability - perfect for engineers and hobbyists who require accurate and mechanically demanding end-use parts. Comparing within Polymakers own range, Fiberon ASA-CF08 displays 50% higher stiffness (3.8 GPa) than the unreinforced PolyLite ASA (2.3 GPa). This composite reinforcement also results in a high quality ASA filament that is less prone to warping, displays excellent overhang quality and requires minimal chamber heating.
- High Heat Resistance - Fiberon™ ASA-CF08 displays heat resistance up to 103 °C (HDT 0.45 MPa), making it perfect for enclosures, fixtures, and components exposed to direct sunlight or extreme heat without deformation.
- High Speed Capable - Fiberon™ ASA-CF08 has been developed with printer compatibility in mind and is high speed capable, enabling printing up to 350mm/s on suitable high speed printers.
- Excellent Surface Finish & Colourful Options - The 8% carbon fibre reinforcement delivers a high quality matte finish that hides layer lines. In combination with 6 unique colour options, ASA-CF08 is also great for applications where aesthetics matter as much as function.
Technical Data
All ASA-CF specimens were printed with 270°C nozzle temperature, 90°C bed temperature, cooling fan OFF and were printed with 100% infil, 2 shells and 3 top & bottom layers.

Received giftcard money to replace my plan-protected malfunctioning motherboard
I've been subscribing to the Asurion protection plan for a while. Recently, an Asus Prime PC motherboard I had bought a few months ago on Amazon stopped working well. I ended up considering filing a claim with Asurion to see if they would either fix/replace it or issue the purchase price money, so I could buy the failed electronics replacement component again for my custom-built PC. I went to the protection plan's website and started the claim filing process but couldn't find the category my failed component would be under in order to select it from the drop-down list. I ended up messaging the live customer service. The chat messaging was somewhat slow, the agent told me they were experiencing some communication delays throughout their systems. Ultimately, the agent was very kind and understanding, and completed the claim filing process for me on her side by asking me to provide the necessary info such as the item's product name, date of purchase, price before taxes, etc. I received a printable UPS shipping label in the email, printed it, and returned the item in the mail. Approximately 2 days later, I received an Amazon giftcard code in the email with the dollar amount equal to the item's price before the sales tax. Then I redeemed the giftcard code on the Amazon page and proceeded to apply the giftcard money to my next purchase of a replacement Asus prime motherboard, and it all worked out successfully. Therefore, I had no issues with the protection plan service and recommend it to others.

Fast and easy but I dont trust the process to be fully automated.
The process was very smooth and fairly quick. The only challenge I had was that the CLAIM status showed complete but I had to manually go look up the status. There was no email or notification it was closed. After manually checking the status, I called customer support and they said since I called in, they would process the payout. I wonder if I didnt call in if they would have processed it? Also, the phone rep said they would issue me a amazon egift card but then the next day I received a email saying they mailed out the payout. Very poor communication but so far the process was easy and fast.

Knowledgeable and helpful
I purchased a new Sony TV and was having a lot of trouble coordinating the settings. After struggling for 1.5 days, I gave up and called the number for Asurion. There was a reasonable wait while I found the "right" tech person, but it was worthwhile. He was knowledgeable and patient. He gave me confidence and we worked together to solve all my issues. At the end he became pressuring, wanted me to buy a monthly gig with them.

They honor their product.
I've been dealing with Asurion for over a decade now. They're my first choice when making a purchase that I know I'm going to have around for a while. Asurion backs its product to the hilt. I purchased a mid-range priced printer about 2 1/2 yrs. ago along with a 3yr. warranty from Asurion to cover any unexpected 'surprises' that might happen to pop up. Fast forward to approximately 3 months ago, when my printer decided that it wanted to start acting up. The print quality was taking a nose dive; colors were beginning to drop out, showing streaks and fading. Clarity and sharpness are virtually gone. I contacted Asurion about the problem. I couldn't have found a nicer rep to deal with. She said not to worry and within minutes had the situation under control. She sent me all the information and pre-paid postage on how to pack and have my unit shipped to their repair facilities. In less than a week my unit was repaired and returned to me. However, this is not the end of the story. Within a few days, my unit was acting up again and doing the same thing it went in for. Again, I got hold of Asurion (Same great service, different girl). We repeated the same process as before, but this time the unit was there about a week longer. When I finally received the unit, I immediately hooked it up and put it through the numbers, testing everything. To be blunt, the print quality was worse than the 1st time it went in for service. After voicing my displeasure (basically having a hissy-fit), I regained my composure and contacted Asurion, again! This time they told me that since their techs were unable to resolve the issue and to not have me waiting any longer than I have already, they're going ahead and refunding the total amount I paid for the unit. Even though it was somewhat of a Pain-in-the-ASS to go through, I couldn't be happier. Within 48 hrs. I had my refund in hand and I turned around and purchased a replacement Printer. Moral to the story, have a contingency plan, Just in case. Check out Asurion: Great customer service - Nice people, very competitive pricing for their products and they honor their word by their actions. Highly recommend Asurion to anyone.
