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.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.

Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Not as good as chuck it anymore
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
I have bought these before and the where just like the chuck it balls. These are not those balls. The are lighter and my dog has already cause damage to one
