Newbie using carbon filament
Hi all, complete newbie here, in fact I haven't ordered my Prusa i3 MK3S+ yet but will do so today. I plan to print large focus wheels for scopes (150mm diameter) which is a pretty large flat print. I also plan to print using carbon blend filament. Now my question is which carbon filament should I use considering that the printed material would be exposed to long periods of sunshine and rain in winter? My choice although I have no experience whatsoever, is PETG carbon or after reading some good reviews Prusament PC blend carbon fiber. Would these be OK, should I go for another filament? I also know there may be issues regarding warpage should I use pads or brims, glue, print sheet texture, print settings etc. I have added textured PEI sheet to my cart and Nozzle XE3D V6 0.4, is this a good size nozzle for what I need, should I add anything else before I go ahead with the order? The printer will be located in a room with a temperature (presently in Malta) of around 30 deg Celcius and 50-60% relative humidity. Sorry for the long post and all the questions, any info would be greatly appreciated. Thanks
150mm will be ok once you have your first layers dialled in.
I would begin with PLA and make prototypes for testing; save the more expensive filament until you are sure of the design. Why are you intending to use carbon fill?
Cheerio,

Mainly strength, because I am also designing an adjustable hamster (foregrip) for my Field Target rifle and would like all the printed parts to match.
RE: Newbie using carbon filament
I do agree about printing out a PLA version of the design, and now that have been thinking about it maybe I may just use standard PETG, it may be strong enough for my purposes.

I've been using Priline CF PC and really like it. It's my go-to for parts that will take a beating.

RE:
I really like carbon fibre Nylon.
If it is really dry it prints as easily as PLA and is extremely strong.
Here's the MK3S+ fan shroud made from Polymaker PA6-CF on a stock MK3S+ (except nozzle: E3D hardened steel 0.4mm):

I recommend a hardened nozzle if you are not already using one. They will last longer CF filaments.

RE:
This filament is very easy to print. I'd just suggest turning off cooling completely as it will get brittle when cooled.
Here are a few of my prints. The long part was around 12cm.
Brim was unnecessary, it doesn't show any tendency to shrink.
It also takes threaded inserts very well (I've used original Bossard BN1054 M3 ones for my new extruder)
RE: Newbie using carbon filament
Good weather and UV resistance is, for example, ASA or ABS. I myself like to use CarbonNylon from 3dxtech for such purposes: https://www.3dxtech.com/product/carbonx-pa6-cf/
3dxtech offers a lot of different carbon filaments.

RE: Newbie using carbon filament
I can’t argue against the use of 3DXTech CF filaments. They are pricy but they are premium is quality.

RE: Newbie using carbon filament
Hi ov_darkness, which filament are you referring to?
RE:
Prusament PC Blend CF.
I strongly suggest using either Microswiss M2 or E3D NozzleX. They are functionally very similar.

I have Nozzle XE3D V6 0.4 in my basket, as I am about to make the order but I need to know that I am ordering all that I need before I go ahead. Regarding the inserts, what method do you use, do you use a soldering iron to heat them before inserting them?
