I saw that Extrudr has PETG CF and now Prusament has, too.
Has anyone tried either of them and what do you think or expect of it? Does it make sense for the mechanical properties or is it mostly cosmetic just like with most PLA CFs?

@warm stag didn’t you print your bed mount of petg cf

I did for prototyping but it wasn't anywhere near stiff enough for real use. I had it eventually cut from 4mm carbon fiber

The nylon pa 6 cf was nice and stiff almost good enough for a drone arm

I've heard it's easier
The polymaker needs a 100c chamber i can print it at 90c good enough

The ezpc is a pc-pbt mix
I have a #1058923420689113119 channel post over then when it comes in would love to see your results

I designed my own enclosure for the switchwire. All acm besides the doors and it all bolts together, no tape. I'm lining the acm with 8mm insulation foam
Should be able to get some nice ambient temps
So I bought the cf-pc-pbt for new parts and have high temp belts and motors coming lol
Might do 48v 48mm stepper for Y and normal 48mm motors you gave me for a/b
With the CF carriage and 9mm belt mod I'm able to push 14k accel @ 500mm/s lol. Whips the bed around.
Here's the petg-cf
Its really easy to print, easier than normal petg and layer lines are nearly invisible

Endstop Switches lose all tolerance at 80c
Look up a euclid high temp if you need a probe
Don’t buy 0.8 high temp steppers so loud
If you go stealth burner look at the aluminum carriage i keep pulling heat inserts out at 100c

I think CF materials look pretty nice, and I thought PETG CF might be an upgrade over PLA CF without having to go all the way to something like pc or pa.
I know I saw it before, but I forgot that FormFutura also has PETG CF, I needed to order from them anyway so I just added a 250g spool of that.

That actually looks pretty great.

checkout PolyMax PETG-ESD, carbon nanotubed result in increased stiffness and tensile strength. Similar impact to PolyLite PETG
probably the closest thing Polymaker have to PETG-CF

No it's not 😅 It prints similarly to Push's CF PC-PBT

PETG is a great carrier for a CF fill. The lower tensile/flexural modulus and high durability of unfilled PETG means that CF filled parts tend to not be as brittle as other materials. Also, it retains PETG's great layer adhesion (which fiber fills can reduce in other materials)

Sounds great, can't wait to test it! Would be great if Polymaker had it, too 😁

oh i thought it was the same lol

I bought 500g of that cf-pc-pbt and 750g of the ez-pc-cf
we shall see how "ez" it really is
I have a bunch of polymaker pa6-cf but didn't know it was susceptible to creep
so i haven't found a use for it yet

Tried it today for the first time. Very happy with how it looks like. Couldn't really test its stability/strength yet though

@hard sandal I haven't tried Prusa's or Extrudr's, but I have 3DXTech's and some cheaper stuff from IEMAI. I like PETG-CF, as @remote grail said it seems to take to the CF well. It's not a super material or anything, but I can use it in my car, it looks cool (not a big fan of glossy PETG all the time) and it makes it a little stiffer. As long as the price is right I think it's a really nice material if you need a little more heat resistance than PLA. Also hoping Polymaker might make a reasonably priced version 😉 @fast smelt
Oh, I did have to dry the snot out of the IEMAI first to get good results FYI.
That made all the difference though.
