Fiberon PET-CF17 is a brand new high-speed composite 3D printing material developed by Polymaker to deliver strength and performance without moisture sensitivity concerns. Fiberon PET-CF17 carbon fiber reinforced filament excels at rapid prototyping, offering exceptional print quality and dimensional accuracy. Combining the best of strength, speed, and surface finish into one versatile composite filament.

Features

  • Excellent stiffness & moisture insensitivity - Compounded with 17% chopped carbon fiber, Fiberon PET-CF17 delivers excellent mechanical strength and stiffness for a wide range of jig, fixture, automotive and manufacturing applications. Fiberon PET-CF17 is a "moisture insensitive" composite filament[1] , ensuring excellent mechanical properties regardless of moisture absorption. This is in comparison to parts produced in nylon-based carbon fiber that absorb moisture from the air, a process which reduces tensile strength and stiffness of carbon fiber nylon parts. With Fiberon PET-CF17, users can print end-use parts for a wide range of industries without concerns of mechanical performance if the component is exposed to humid or wet applications.
  • High Heat Resistance - Featuring a heat deflection temperature of up to 147°C after annealing [2], Fiberon PET-CF17 heat resistance delivers an easy-to-use composite material for a wide range of end-use applications.
  • High Speed Capable - Fiberon PET-CF17 has been developed with printer compatibility in mind and is high speed capable, enabling printing up to 300mm/s on suitable high speed printers.
  • Dimensional Accuracy & Excellent Surface Finish - Carbon fiber reinforcement in Fiberon PET-CF17 delivers an outstanding surface finish with fantastic dimensional accuracy and low shrinkage during printing.

[1] Moisture insensitivity 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 PET-CF moisture absorption is minimal and doesn't impact the mechanical properties of the part. For best printing results PET-CF17 should still be kept dry during printing and storage.
[2] Fiberon™ PET-CF17 displays the best mechanical and thermal properties when fully crystallised. The printed part will not reach full crystallisation during the printing process, an additional step is required: Annealing. PET-CF17 can be annealed in the oven at 120˚C for 10 hours. Please see settings & specifications tab for detailed annealing instructions.

Versatile and athletic top
Size: Medium, Color: Black Gray Blocks, Size: Medium, Color: Black Gray Blocks
This sleeveless shirt is so cute! I like the collared look and the cheetah print. The material is super lightweight and breathable, with solid moisture-wicking It dries fast too – huge plus. The collared design gives it a polished look that works on the golf course or grabbing lunch after, and the stretch feels comfortable without being clingy. Sizing ran pretty true for me, and the UPF protection is a nice bonus for sunny days. I think it’s versatile enough that the top can look nice with some slacks for an office vibe too. Great value if you’re looking for performance without spending a fortune.

Cute striped athletic tank
Size: Large, Color: Pink Purple Stripes
such a cute and comfortable athletic tank to wear for many activities! The material is lightweight and breathable but is also so soft and makes wearing it super comfortable for any athletic activity or just for wearing casually on a hot summer’s day. The fabric seems very high-quality and has some stretch to it. The tank top does fit true to size. The collar is a very cute detail and makes this tank top feel fun and flirty and feminine. I love the pink stripes pattern. It looks cute tucked into a skirt or shorts. This is a cute tank top for Pickleball, tennis, golf, or simply just running errands. This has washed well and I usually hang up to dry all of my athletic wardrobe. It does dry quickly and does not dry wrinkly even when just clipped up to dry. I think it is a good value for the tank top that you get and definitely looks like it came from a sporty sports outlet and definitely doesn’t look or feel cheaply made. Very happy with this tank top and would definitely recommend!

Good Quality, Runs Small
This top is just as described. Great color and quality. Fabric has some stretch. Would be great for golfing. I usually wear an XL, which is what I ordered. The shirt is very snug. I prefer tops be more loose so if you are the same, definitely size up! Good value though for the quality.

LOVE this brand
Size: Medium, Color: White Blue Florals
Okay I am really falling in love with this brand I have a couple of shirts and dresses and pants and I absolutely adore all of them. The material all of it is so much better, such top quality and extremely soft and wonderful feeling up against your skin more so than you would ever think. The size is perfect I ordered a medium and I normally wear a medium, it is perfect for playing golf or tennis, it is breathable so as I run the wind cools me off. I like the way that the shirt looks and it stretches a bit so you can you know get it on but it does not lose its shape or anything like that. It washes and dries very well it keeps its shape and does not shrink and honestly in my opinion it it feels like it gets softer the more you wash it the more you wear it I don't know

Pretty in pink!
Size: Small, Color: Pink White Florals
I ordered this top in the pink color, and it is absolutely lovely! The print is feminine and cheerful, making it perfect for golf, tennis, or any casual summer outing. The fabric is soft, lightweight, and breathable, which is a must for warm weather. It does a great job keeping you comfortable, even on hot days, and the sleeveless design allows for easy movement. My only note is that the fit runs a bit snug. If you’re between sizes or prefer a looser fit, you may want to consider sizing up. Other than that, it’s a very well-made top with a flattering style and beautiful color. Overall, a pretty and comfortable addition to any warm-weather wardrobe! 💗⛳🎾☀️
