Has anyone tried PTFE tubing as a liner for the stock extruder throat ?
I'm wondering if this would help reduce heat creep when printing with PLA.
I do not have the same printer, but my ctc does have a Ptfe lining in the throat. I extruded without it once and it was not good. From my opinion it should help.
On the new extruder I have just ordered the E3D V6 it comes with PTFE tubing which helps printing difficult filaments like PLA, Wood and ninjaflex etc
The E3D v6 does not have PTFE lining. The tube terminates at the top of the PEEK barrel. It does not extend down into the nozzle.
Yes it does it reached down to the heater break look on their website
You would need to bore out the extruder for the OD of the PTFE.
I have 2 of these so I know. I also see the picture you're point to on the website. But believe me when I say that PTFE tubing is not a liner and it does not go down into the hotend like the traditional J-Head hotends. The PTFE tube of the v6 only goes into the opening, but it does not act as a liner. They don't call it "all metal hotend" for nothing.

It even says in the video on there for the advertising now unless they are lying...?

According to this link which list the contents of the box there is no PTFE tubing listed. Nor is it shown in any of their engineering drawings. The bundles of tubing they sell as spares are intended to connect between a Bowden extruder and the E3D hot end. It does not actually go in to the hotend or cold end, but just the compression fitting that all Bowden hot ends have.
Not wanting to argue here but I think you may have been ripped off or got an older model like the V5.
And yet from the same page under description - "Although our latest v6 hotend has a PTFE liner inside the hotend this liner is never subjected to high temperatures so there is no risk of damaging the liner through overheating."
Which matches mine's assembly, for 1.75mm direct feed not Bowden.
But - there is one variation without it. From the assembly directions:
These steps apply only to 1.75mm Direct, 1.75mm Bowden, and 3mm Bowden users. 3mm Direct does not use any PTFE tubing.
The PTFE tubing in the 1.75mm Direct configuration is not optional, you must use the tubing or the HotEnd will not function properly.
The tubing should be inserted from the top of the now assembled hotend and pushed as far down into the hotend as possible.
In the 1.75mm versions the PTFE tube actually runs through the Heat Sink and into the Heat Break, please ensure the tubing as seated as deep into the hotend as possible.
Well this is what I see on the website guys I'm not arguing I'm just saying what ive seen on he page I ordered the Bowden feed and it shows it goes through the collar and into the cold end
It should be here tomorrow so I shall start a thread on it when it turns up
My Guess on the confusion of some is this little note towards the bottom of the page just above the images that I linked..
(PTFE Liner only present in 1.75mm version - 3mm Bowden has partial lining - 3mm Direct has no lining)
Yeah and in the video it shows that the lining goes past the collar and in to the heat break that's where it located from looking at the video when they explain it
What you are seeing is correct. But what you are seeing is not a PTFE liner. The PTFE tube ends where the PEEK barrel begins. In order to act as a liner, like the traditional J-head hotends, the tube has to go all the way down closer to where the nozzle is. The E3D does not do that. The region where the PTFE tube ends and the PEEK begins sees very little temperature increase. Therefore the tube does not act as a liner nor was it designed to be a liner.

Not gonna lie carl, but if you don't know you shouldn't talk about something... Yes there is PTFE tubing that runs through the heatsink up to the heat break. The ptfe tubing runs right down to the heat break on the 1.75 v6, bowden or regardless, thus the "universal" designation by e3d...
[s]Also evanalmighty there is no PEEK in an e3d v6, v5 yes, but not the V6. The heat break is stainless and the heat sink is aluminum. That's it. [/s]
There is no PEEK in the e3d thus the reason why it called the "All metal hotend"! If you are not an engineer (or a drafter even) don't try to interpret engineering drawings for others.

Another selective reader are we? Did you not notice my next comment about the little Disclaimer hidden in the middle of the page that could be a source of confusion? I quoted their site, that was not from me. So I was not saying anything.
If you want to stalk me that's fine, but please do it in private. I don't like to share my private life with the other forum members. They might get jealous.

I don't have time to stalk you, but you were telling someone who I have been helping some thing that was not right... As far as your personal life I couldn't care less. And trust me no one would be jealous GG
Also as far as being a selective reader not quite true since I saw that lame attempt to cover your mistake...
Gentlemen please,
If we could keep the conversation constructive?
Thank you
FYI. There are several E3d users and even experts that would be happy to answer your questions.

I dont appreciate being accused of misinformation when all I did was linked a page and quoted it straight from E3D's website. If anything they are giving the misinformation by not telling the full contents of the box or failing to update that page after design changes. I dont see how I was in the wrong here. He simply needed to say THAT information/page may be wrong. Not that I was wrong.
I am getting tired of being pushed around by Elitist attitudes.
Listen guys instead of flat out saying a person is wrong which makes you all look like jerks. Simply say a persons information COULD be wrong or your source COULD be wrong. See how less aggressive and Elitist that sounds? Sorry for derailing.
You don't need to be engineer guys to watch a video and watch it showing the PTFE lining locating in the heat break!!
I can read engineering drawings just fine as I work in aerospace engineering and use engineering drawings which are more complex than the ones they supply....
I'm not having some one turn to me and say in lying when I have supplied an image which clearly shows what I said!!
Further my message here is a screenshot of the actual video they have put up for advertising
As you can clearly see the PTFE lining locates IN THE HOTEND and is all the way through
This image shows a hotend that has a PTFE 'liner' that goes through the stainless steel barrel. The entire barrel is bored out to accommodate the 'liner'.
http://swindon.hackspace.org.uk/blog/ho … nts/33.png
Here is an image of the cross sectioned E3D v6 barrel. The PTFE tube leads into the opening of the barrel and terminates. So you can call it a liner if you want, but it doesn't act as one. In order for the 'liner' to aid with printing PLA, it has to go as far down the hotend as possible. Some hotends, like the ones made by CTC, even has the brass nozzle bored out so that the PTFE liner can go all the way into the nozzle.
Have you actually looked in to these? They say on the video it can print any kind of filament thats out.... so they have clearly designed it right so that it can print PLA

Yep an e3d v6 will print pretty much anything you can throw at it
Just for fun I've been dialing in PLA on my v6. Here's a couple prints (attached).
And yes, the PTFE does go all the way through to the heatbrake.

It is a liner. The e3d v6 PTFE runs all the way to the end of the cold side of the heatbrake. Any area beyond the PTFE is the hot zone--the filament is supported all the way to the point that it melts. It doesn't need guidance inside the heatbrake because the polished walls of the heatbrake act as support. The few issues folks have with PLA on the v6, from my reading, arose with too much retraction.
