PLA vs PETG vs ABS vs Carbon Fiber PC vs Polycarbonate Thermal Test

[@scifi_shop]

What would you like for us to test next? Thanks for watching!

[@elidicken7712]

CF polycarbonate and nylon with and without Cf?

[@cyphre]

Maybe some color grading profiles since you filmed in a flat profile?

[@enlightendbel]

If you need REALLY heat resistant, use Ceramic filament. That crazy Portugues Integza made 3D printed rocket nozzles with it and they can get glowing hot without breaking.

Dont like that kind of music but i'll make an exception for this guy 💚

[@markthompson5983]

Some things to consider: Polymax PC is not pure PC, with its tg around 113c compared to pure PC's tg of 147c. Gizmodorks PC is proper polycarbonate and its HDT@1.8mpa is around 140c. The CF filament you used here was also polycarbonate, however it was blended more than the polymax PC making it easier to print, which resulted in its earlier failure. Normally a filling of glass or carbon fibers increases the HDT of a part AND makes it easier to print. Also printing polycarbonate releases BPA fumes, so venting or filtering it through activated carbon is required.

[@3d.printed.flight]

No the cf makes filament easier to print because it prevents warping

[@ravemasters9564]

Have you experimented with CF15 Polyamide ? In my experience it is also a good option.

[@markthompson5983]

@ravemasters9564 From polymaker? Yes, and I've had a pretty solid experience with it so far besides some minor issues with layer adhesion. Otherwise it's performance is quite incredible for how easy it is to print.

[@markthompson5983]

@3d.printed.flight If the carbon fiber used in the filament is chopped into strands then yes, the cf and the lower tg of the filament makes it easier to print. However, if the carbon fiber is a milled powder then it provides no benefit, and I believe it may actually cause more warping due to the added nucleation sites for crystallization that the powder provides. But that last part is just a theory, I need to do more reading to determine if that's true.

[@DangaRanga]

Great video! I'm surprised how little separation there was in the grand scheme of temps.

[@ravemasters9564]

Thank you for taking time on this experiment If u Look closely, 114 is the PC failure In my opinion material failure should be marked at the first sight of movement not the last. Also . When you are raising temperature so rapidly parts are not heating as fast so what you are creating is the hot outer layer and colder core. I suggest another test where you increase temperature one degree per minute on small parts like yours . What I have noticed is that Polycarbonate tend to warp somewhere below 85 Celsius and Polymaker one below 79 on 1cm diameter round rod at 72mm length. I also suggest you try Polyamide CF15 I’m not a testing guy but it is working fine for me in temperatures above 100, honestly I have no way of measuring it exactly but I’m confident it will outperform PC-CF5 (my guess 120-130) looking forward to your next video.

[@muchmore344]

I always print in PC from PolyMaker. and it is true that warping is an issue, if the shape is not right. I get the best results with: Magigoo PC, 120°C printbed, 6round of brim, 275°C Nozzel,. AND importantly you have to remove the part when the printbed is >60°C. If you let it cool down all the way it can destroy glass surfaces.

[@scifi_shop]

Thanks for sharing.

[@josiahong5177]

somehow i managed with a small brim to print a 200mm long big polymax pc part (it was like 150g of material. kinda hurt but my petg parts kept breaking) and there was zero warping

[@rmsr123]

Tiny bit of advice here, you should always say/include the name of the plastic being infused with CF, because any plastic can be mixed with it. And as you correctly stated, the filament only has a small % of CF in it. I believe you never say which plastic it is, so I'll assume it's CF PC because of the health risk study you linked.

[@wturber]

Exactly what the published specs would predict. Nice to see it demonstrated that the published info on these materials is fairly accurate.

[@mikedoingmikethings702]

Awesome test where you have the timer and thermometer on the same screen. Have you made a video where you annealed them? Thanks!!!

[@scifi_shop]

I've tried annealing, it's very strong but hard to keep its original shape (haven't made a video yet). But since this video, I've been doing production strictly with PC carbon fiber, it has all around good attributes.

[@bluegizmo1983]

I'm not a fan of PETG. I still use it occasionally, but it's stringy as hell, and that's not an issue with my machine as I have a direct drive system that is very dialed in, every other material I use prints fantastic but I have never been able to eliminate PETG stringing. That Priline Carbon Fiber Polycarbonate is one of my top filaments, I use that for 90% of my prints, I love that stuff. You need a hardened nozzle to print it, and an all metal hotend because of the temperature requirements, but it prints great with a nice finish, strong, and very temperature resistant.

[@scifi_shop]

Thanks for the tips.

[@CC-kc5lb]

As for your test pcs why is the CF not named as a material not an additive to a base material so what the the base material of the CF sample?

[@scifi_shop]

Sorry, I thought it's was on camera. It's also Polycarbonate base.

A lot of tough resins out there with incredibly high temperatures. I believe I've seen some claim 140-160C. I usually mix in some flexible resin with toughness or abs like resin to deliver a similar PETG feel.

I think it'd be close. I'll do a follow-up video on this. But personally I don't like annealing because of shrinking and warping. Most annealing you've seen done are on parts that are very small and dense; it's not suitable for most dimensions and density.

Great content but sorry for bringing this up, but could you please consider throwing a LUT or some serious contrast over your footage? If I had to guess, you're shooting S-log or some other flavor of log and while the washed out look can work for certain things, it's not really suited - in my opinion - for an informative YT channel. Actually, you don't even need to shoot in log, you can just pick a punchier profile and skip the LUT step in post altogether;) Anyways, I came here for the PC content and will sub either way;)

[@Sifu-Myers]

Hey do you possibly know how much lighter carbon fiber filament is to pla? I'm told its light weight but im not sure just how much lighter it is when comparing the two

[@scifi_shop]

They generally mix in only 5% carbon fiber strands to keep the plastic property, so I can't imagine it is that much lighter (more significant for larger and dense prints). I'll do a quick test next month when I get a high precision scale.

[@Tarex_]

All in all great video! Gotta say though, that is some weird PETG that needs 240-260 with cooling on, usually it's in the range of 235 and cooling makes it stringy as hell.. Why not try PC\ABS? It supposedly is easier to print and retains the properties of PC well enough, and check annealing, maybe that can get you the result with easier material

[@scifi_shop]

Thanks for suggestion. I do a follow-up video in the future. The printing temp is really depends on the printer and filament brands; how the hot ends are designed and their sensors. I always note these specs down on successful prints.

[@Tarex_]

@@scifi_shop of course, each filament brand is different, i use ASA on my engineblock as a badge,2 years, no change, PETG as an air filter housing, cold enough, works, but i used carbon petg on the engine block, that deformed from the heat, so now machining it from Aluminum

[@heyjackfpv5469]

will an ender 3 v2 print that filament with carbon fiber ?

[@scifi_shop]

The ender 3 does go up to 250c, but I believe you'll need to upgrade to an all metal hot ends because the PTFE tube may degrades with such high temperature. Also you'll need an enclosure to prevent warping.

Yep never go back to priline carbon Fiber PC again. It mostly abs with little PC. I test mechanical strength is weaker than Pure PC like 3dxtech have. Polymax is a better version but up to 113 °C. The point in here that if it expose to long term temperature can cause deformity thus the best to go if you want real pure PC up to 145°C softening point and 137°C heat deflection but with some degree of difficult hard to print a big piece warping free is 3dxtech PC cor Gizmo Dork PC ( clear).

Nice effort, but this experiment doesn't have any sense. You are changing temperature way too fast, the material did not reach the temperature you are measuring. So all the temperatures are much higher than what actual materials can withstand. You should have let it exposed to each temperature for at least several hours (days, even better), and then you could get some real numbers. For example, I have got PETG bending at just over 50°C, and ABS bending at only few °C more, when under some load.
