Description

Polymaker Fiberon ASA-CF08 1.75mm Filament 3kgFiberon 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.

Great Stuff!
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-30
Purchased for my husbands F-150 Truck , his engine was making a weird noise and he thought he was going to have to get a new engine but a friend recommended to change his oil and use this one. Boom, it worked! Couldn't believe it cleaned the engine out and the noise went away. Engine seems to be working fine now. Will definitely use again!

Super nice and smooth, so much power! Car feels nimbler. Worth the price
Size: 5 Liter, Style: 1 Pack, Configuration: 5W-50
I normally don't buy such expensive engine oils (normally buy cheap diesel truck oils add in MoS2). However, this one was well worth the purchase. Engine feels substantially smoother and quieter. After running for a while, the car feels a lot nimbler. More power, and as if it simply wants to keep moving rather than whining. It glides like a magic carpet

Give the green light to the green oil.
Size: 5 Liter, Style: 1 Pack, Configuration: 0W-20
Great oil. I've used Liqui-Molly in all my vehicles and it always performs. Theres very little burn off between changes and I noticed cleaner, quieter engine. I've used this in many different car brands, it never disappoints.

Car Runs Smooth, Less Friction, and Improved Performance at Start Up and Underload.
Size: 5 Liter, Style: 1 Pack, Configuration: 0W-20
I kept hearing things about this oil from a few friends that work on cars and from my "go-to" mechanic. I was previously using Mobile 1 0w-20 on my 2024 4Runner and my wife's 2025 Outback Onyx, and this time around I decided to try it on both cars as they needed an oil change. So far I am happy with the change for both cars. This is good oil quality, smooth engine running, and noticeable oil lubrication at cold start. I am getting better MPGs mileage on both cars. Also noticeable engine is running with smoother. I had to lower my car window to check that my 4runner was on as it was quiet. I will update my review after a second oil change with this oil on both cars.

I didn’t think I’d get excited about motor oil, but here we are—Liqui Moly Molygen 5W-40 has officially made me feel like a car enthusiast. If you're serious about keeping your engine purring like a kitten, this stuff is like giving it a spa day with an energy drink chaser. First off, this isn’t just any old motor oil—it’s high-tech motor oil. We’re talking German engineering at its finest. The neon green color? Oh yeah, it looks as cool as it sounds, and trust me, when you see that green oil running through your engine, you know you're in for some serious performance. 🟢💯 Why do I love it? Engine protection: This oil is like a security blanket for your engine. It reduces friction like a champ, so parts glide smoothly, which means less wear and tear. Translation: your engine will thank you with better performance and a longer life. Fuel efficiency: You’re not just getting a smoother ride; you’re also saving some bucks at the pump. The way this oil cuts down on friction helps with fuel economy. It’s like the gift that keeps on giving. Cold start-ups? No problem. Whether you’re dealing with a chilly morning or scorching summer, this oil handles temperature extremes like a boss. It maintains its viscosity so your engine stays protected regardless of the weather. And did I mention the Molygen technology? It’s not just a fancy name—this oil has additives that coat your engine in a protective film, keeping it running smooth and reducing the risk of damage, even during high-stress drives. Final thought: If you're looking for an oil that’s as serious about your car’s performance as you are, the Liqui Moly Molygen 5W-40 is it. Your engine will run smoother, quieter, and stronger, and you’ll feel like you’ve just upgraded your car’s lifeblood. 🚗💨 Plus, that neon green color? Total conversation starter at the garage. 😉
