Our entry-level composite filament featuring recycled carbon fibers. Inheriting the printability and performance of PETG, while gaining enhanced stiffness from the carbon fiber reinforcement. Print high-speed, moisture-insensitive, and low-creep prototypes with exceptional dimensional accuracy. PETG-rCF08 strikes the perfect balance between affordability and functionality, empowering you to quickly create durable, accurate prototypes.

Features

  • Affordable & Easy-to-use - Fiberon™ PETG-rCF08 is a cost-effective recycled carbon fiber reinforced PETG filament billed as the "PLA of engineering materials". It inherits the comprehensive performance of PETG, featuring recycled carbon fiber for enhanced surface texture and improved mechanical properties.
  • Recycled Carbon Fibers- Fiberon™ PETG-rCF08 utilizes carbon fibers from end-of-life wind turbine blades, these fibers are certified to the Global Recycled Standard by TÜV Rheinland. The use of recycled carbon fibers delivers a more sustainably sourced composite filament while maintaining the mechanical strength that users come to expect from carbon-fiber reinforcement.
  • Dimensional Accuracy & Moisture Insensitivity - By delivering fantastic dimensional accuracy, low moisture sensitivity[1] and low shrinkage during printing, Fiberon PETG-rCF17 is well suited for rapid prototyping and a wide range of functional applications requiring durability, accuracy and surface finish.
  • High Speed Capable - Fiberon PETG-rCF08 has been developed with printer compatibility in mind and is high speed capable, enabling printing up to 300mm/s on suitable high speed printers.
    Excellent Surface Finish - Fiberon™ PETG-rCF08 3D prints and renders parts with an attractive surface finish thanks to the PETG's excellent fluidity as a matrix material and the 8% carbon fiber reinforcement.

[1] Low moisture sensitivity does not describe whether the filament should be kept dry for optimal print quality. This description of moisture insensitivity is in the context of the end-use application where extremely moisture sensitive materials like PA6-CF see a significant reduction in mechanical properties as the part absorbs moisture. With PETG-CF moisture absorption is minimal and doesn't impact the mechanical properties of the part. For best printing results PETG-CF should still be kept dry during printing and storage.

All PETG-rCF specimens were printed with 270°C nozzle temperature, 60°C bed temperature, cooling fan 0 - 50%. Samples were printed with 100% infil, 2 shells and 3 top & bottom layers.

Comfy and cute.
I was looking for a Converse alternative for a multitude of reasons. These were perfect. I love the slip-on style. The leather laces stay in place much better than the Converse cotton laces and there is way more sole support, which is a huge plus. I purchased these in black about a year ago and then went for the camo pair. As for the black pair, I wore them regularly for a year. After that time, the shoe didn't feel as comfortable anymore, and the fabric outer around the ankle began to fray, and the white outer trim was beginning to detach from the bottom sole. With that, I was pleased with how long they lasted. As for the camo pair, I anticipate the same quality and comfort. While super cute, the only draw back is the mismatched pattern. If you look at the pics, the one shoe has more gold embellishment at the toe area and the other one doesn't. This bothers me a bit as I would have liked it to match. Otherwise, I'm happy with both purchases so far and will continue to buy them in the future.

Cute but no so comfortable
I previously owned a white sperry leather shoe that I bought from Marshall’s for about $35 & absolutely them, they were so comfortable , cute & great price.After running that pair down, I decided to buy another pair and found out the shoe was discontinued. The closest thing to what I had is this, the white crest vibe in leather. I was disappointed that this shoe was not as comfortable and didn’t fit quite the same. The back ankle part of the shoe caved into my skin and hurt. Sadly, I do not recommend this shoe for much walking. I hope Sperry decides to make this shoe more comfortable because it is cute.
