agreed. PETG can't do anything that this can't. While we're at it, ASA needs to replace ABS

Such good layer adhesion that they fuse together?

If abs or ASA prints break on the layer lines they were not properly printed. Most people think they need an enclosure for abs only because of warping, but if the chamber temperature gets above 50°,60°C even 70° Prints and especially layer adhesion get extremely strong. I print at roughly 60°C and my prints are tougher than petg.

it is a relatively recent development :) Now taking ideas for videos!

Thanks Courtney!!!

Yep, that's it, thanks for the tip :)

@@3DJake_Official Thanks for your response, and all within 12 hours - that's what I call kundennah ;) after watching the video further I saw that you do explain it later on, but it had me bamboozled for a while. Maybe you can add that in your next comparison video, it would help a lot :)

1:21 "...polycyclohexylene diamond polycyclohexaline dimethylene terrathalate glycol modified polycyclohexaline dimethylene terrephalic glycol modified we're just going to call it pctg from now on pctg is still a relatively unknown filament..." Das Transkript tut sich mit unbekannten Ausdrücken auch schwer, aber je nach Muttersprache muss man sich die chemischen Bezeichnungen eh erklären lassen, wenn man nicht vom Fach ist.

Happy printing!

Ah noted, we'll tone it down next time :)

🤣 Hah!

Really good point, the layer adhesion is awesome on PCTG.

Never actually tested that sorry :(

Usually the natural color is best when it comes to strength because it doesnt have any adidtives however at same time its worst for outdoor usage as it doesnt have UV protection

Yep, not much different from PETG besides the temperatures. Hotend: 255 Bed: 95 Cooling: 50% Everything else is pretty standard.

But they're not equal in chemical resistance and PLA would not be the choice filament for something that needs impact resistance.

@@3DJake_Official they looked very similar for the chemical tests, it definitely is less impact resistant for sure but PCTG doesn't seem to be enough of a step up over PLA for the price.

@@deltacx1059 It is definitely a speciality filament for sure but you saw the acetone test right 😂 I think PCTG has more of a niche that is in between a flexible filament and something rigid like PLA. If you really want a chemical resistant polymer then the go-to choice is always going to be polypropylene but polypropylene is quite flexible which limits its applications.

@@3DJake_Official definitely right on that, last i touched 3d printing was in 2019 and just got back in so I'm not sure what has actually improved, is PLA even still the best budget/prototyping option or has something come to replace it?

@@deltacx1059 oh yeah for sure and that is not gonna change anytime soon but for functional prototyping you gotta need something a bit heftier and things have changed there, PCTG is one example but there is also ASA, pre-2019 there wasn't much of that on the market, same goes for PMMA and PVC, we even have teflon and kevlar infused filament in the shop now but the main thing that has changed is speed - we're getting a new printer in a few weeks that can print at 600mm/s, crazy.

Good questions. We haven't tried exposing it to high humidity but I think it would react quite similarly to PETG. In which case, using a dehydrator would be enough to fix it. We have one in the workshop, its just a normal food dehydrator, works really well. We have tested the filament up to 200mm/s on an FLSUN V400, only a tiny bit of underextrusion was noted at one part and a tiny bit of stringing on thin parts on the top of the model where the layer time was really brief. Tried again with a flow adjustment and only the stringing remained, it was quite minimal and less than what I would expect for our own PETG. In terms of surface quality, the PCTG was noticeably better. We'll post a detailed model printed at high speed in the coming days so you can see what I mean.

@@3DJake_Official Thanks for your answer, that's a lot of good info! I've read that as opposed to PETG, PCTG DOES recrystallize when heated beyond glass transition temperature and therefore can be annealed to increase heat resistance and stiffness even more. So far, I haven't found much more info on how exactly to control the process, like what temps to use for how long and expectable warp and such.

Sounds like a good follow up video!

Sure we can put it on the list, same as this? Testing it to the breaking point?

Since you call it Easy ABS I’m assuming that its easy to print than any other regular ABS, I’m very interested in the printability aspect of it.

PCTG is very close to ASA in terms of UV resistance however ASA would be better for most outdoor uses due to its higher strength at elevated temperature which is quite relevant in summer time.

Oh no, it was so long ago, I can't even find the source :(

Definitely not as bad as ABS but I would recommend being able to ventilate your room after every print, doesn't matter what the filament is.

@@3DJake_Official Okay Thanks

Can you print PET?

@@philipp6682 Yep. It needs higher temperatures than PTFE-lined hotends can safely do - min 270 to flow at all, and 285 or more at high speed - which is basically the whole motivation for PETG. Otherwise PETG is an inferior material in pretty much all ways - the gunking/blobbing, poor layer adhesion, difficulty achieving high flow, material creep, lower HDT, etc. Unfortunately PET filament is hard to find. There are various projects to make it yourself from recycled bottles, and in the US, Fusion Filaments sells it as HTPET. A little pricy but not too bad compared to other filament types with comparable material properties.

@@daliasprints9798 ahhh thank you very much! :) I didnt know that. Actually im Printing with petg, its stringing and hard to print :(

@@philipp6682 That probably means it's wet. PETG and PET are very hygroscopic and need to be dried right before printing if you don't have a sealed drybox and hardcore dessicant.

Hmm I actually never had to dry PETG before a print but it totally depends on your environment, whether it is humid or not. If your workshop is in a garage, you'll probably have to dry it regularly.

This is so weird, in my experience PETG is not very impact resistant at all. Better than PLA but still not very good imo.

@ It might vary depending on print settings I guess. In my experience PETG is very impact resistant and it sticks amazingly to itself

@ It also depends a lot on PETG brand. Extrudr PETG is weird for example and not impact resistant at all (but prints very nicely, almost as if it were PLA) others are much better.

@emfmuffin Info on the internet generally states that PETG has better impact resistance than ABS which I find strange as so many of our PETG filaments have much lower impact strength than our ABS and from practical experience I see the same too. Not really sure why that is the general opinion.

sorry :(

Pretty sure Ryno is just modified PETG, it prints too cool to be PCTG.
