What is my speed limit?
-
Based on another thread i am involved in, it sounds like its hit or miss regarding brand of PETG. if you are the US then the taulman techg, guidline or blueprint will work well … if you are euro then rigidink
honestly between the taulmans they are all great, just matters whats more important to you, food safe, strength or price.... they are all strong but techg does have a little flex to it with 10mm thick parts.... most important part is as long as your bed is level they print as easy as PLA for me anyways

Yes, sir. I am in the US.
Thank you for the recommendation.
I will check them out.To be able to print PETG at 75mm/s would be awesome. I plan on making table top arcades for my and my girlfriend's kids for Christmas. I found one on Thingiverse that is really nice, but the printing for each one will be a long process.
I pulled up two of the panels for the sides of the cabinet in S3D and at the 35mm/s that I am forced to print now, it would be over 48 hours. I am guessing about 150 hours per cabinet x 4 cabinets, is gonna be a long haul. Not to mention the wiring afterward.I thought I had found my dream filament in PLA+.
It prints as easy as PLA and it really is very strong. But I discovered that it doesn't handle even moderate heat well at all.
I printed all of my new printers parts in PETG and as you mentioned too, I love it. But it's just such a slow going.
I have a piece of a roll of Hatchbox PETG now, that is behaving very well.
I am going to try the exercises above to see if I can gain any speed with it.
I hope that you are right and I just need to tweak things a bit more and it's not a limitation of the filament. -
…............................... I put on a roll PETG. Good grief. I could print it beautifully on my old clone, but this printer just doesn't like it.
I blame the brand just a little. I bought a brand new roll of eSun and I have spent several hours this weekend trying to get it dialed in with no success.Yup, had exactly the same problem with eSun PETG. The worst stuff I have ever tried to print with (and yes, it's the brand, not PETG) - did a write up on blog - see here https://somei3deas.wordpress.com/2017/05/18/esun-petg-and-e3d-edge/. One of my blog followers asked me to send it to him which I did. He found exactly the same issues that I had. He's been trying to dry it out which has improved it somewhat but it's still not good. Our conclusion is that it must have been immersed in a swimming pool for a few days before it was eventually retrieved, vacuum packed and then sold to unsuspecting punters :). E3D Edge (which is also PETG) was so much better - likes to ooze and also has an affinity to sticking to the side of the nozzle but strength is good and bridging is amazing IMO.
I read the article. Nicely done!
Your blog is bookmarked!

Here's some craziness that maybe you guys have run across but it's surprising to me…
The roll of Hatchbox PETG has about 1/3 of a roll left and it's been sitting in an air tight box with a handful of silica gel baggies lining the floor for about the last 1 1/2 months.. There are various other filaments stored in there as well.
I mentioned earlier the trouble I was having with the eSun. So I am tweaking my settings per the conversation I had with Whitewolf with the Hatchbox roll.
I used to have to set my retraction length and speed pretty high to minimize stringing and blobs with the very roll on the old printer.
I am printing out a cylinder and a cube at various settings, and I have Pressure Advance turned off and the retraction settings at about what I had set for PLA and I have ZERO stringing and blobs. I had to double check the label to make sure I grabbed the right roll.
I know I haven't tweaked this machine to perfection. Do you think that maybe it sitting in the storage container so long has effected it? The only issues I have is a little under-extrusion during the infill. But I slowed the speed down a touch and it has improved a lot.I am just shocked. Because of my personal experience and EVERYTHING I have ever read about PETG stringing and ooze is a normal characteristic and I am getting none of that. I think I will let the eSun roll of disaster bake in the box for a few weeks and revisit it just to see.

Well congrats 'cos it sounds like you are getting your printer dialled in really well. It also sounds like Hatchbox PETG is pretty good stuff. The e-sun stuff obviously has a problem which seems to get a bit better if it can be dried out. I'd guess variations between brands could be expected due to the "G". PET is pretty much a basic polymer (Polyethylene terephthalate) but the "G" means it has been Glycol modified. I'm no chemist but I'd guess that this modification process could be a bit variable between brands/manufacturers leading to different characteristics. Then again, you'd think that all PLA is equal but it certainly isn't in my experience. I was once supplied a roll of Verbatim PLA as a more expensive substitute for the "normal" PLA that I'd ordered. It was awful stuff to print with compared to other brands. So if Hatchbox PETG works for you, then stick with it.

Yeah, if you want to improve your dry box a bit there is a guide on Taulman3d website that can put filaments in tip top shape: http://taulman3d.com/drying-materials.html
As deckingman explained TechG can vary Taulman themselves have three different PETGs under different names and different characteristics all three print amazingly so does the rigidink so i had some ignorance as to why others had such issues with PETG i guess i was just spoiled out the gate because ive been using taulman TechG every since i started printing in PETG a couple years ago
