BEST TIPS FOR BETTER PRINTS WITH PETG | Everything you need to succeed with PETG filament

[@d19sbp]

"PETG is as easy to print with as pla" - me after 20+ of trying to print a single thing in petg- *screaming intensifies*

[@envirodaniel]

I'm in the same boat as you... promoted like a miracle filament when it's still finicky

[@kirkd6285]

Same here. 20 prints of a large(310mmx290mm) flat part that .. even though I printed nozzle at 231 degrees it pulled my bed sticker up in the corners and they stayed there making that a high spot on the bed. i am on my third sticker.. no warping? yeah right.. also stringing becomes less of a problem faster retraction speed and enable coasting. A a silicone sock on the hot end keeps the strings from turning to blobs

[@mbisoh]

Me too, lol...

[@MyEyeOnYou]

@@kirkd6285 use Cura petg settings....I change retraction to 3 and speed to 145ms....240 nozzle and 70 bed.....nice smooth prints

[@TheMostTruth]

@@MyEyeOnYou I sort of use these settings too, also fan off.. Like totally off from start to finish has worked wonders for me

[@Aeleas]

I think that strength test was a win for the PLA.

[@MrExpert]

Agree

[@ZtomzukiZ]

That just goes to show that PETG doesn't actually have high impact strength compared to PLA. It does however have much higher tensile strength. I think they should've clarified it's strength properties a bit better.

[@teedjay91]

Tomzuki I think you have it backward, PLA is almost #1 in tensile strengh but very low in impact resistance. ABS have hight impact resistance but low/average tensile strength. PETG is a midle ground in both (and this is not a good place to be in my opinion)

[@IamG3X]

but for how difficult it is to print ABS, it's not even worth it.

I know this video is a bit old now, but I wanted to see if people got any better results with stringing issues. I'm currently using MH Pro PETG (on my second kg - and no matter the brand or type of filament, every roll gets its own EM calibrated). MH recommends 245+/-10C for this specific type of filament. After multiple adjustments to retraction settings, I couldn't get rid of the stringing and additional blobs. I went back to the basic tests for temp. Printed at 225C (with manageable but still annoying stringing, remedied with a heat gun leaving some blobs), then at 235C (with severe stringing, not fixing without significant post processing i.e. sanding, filing, etc.), and finally at 220C (with very minimal stringing, easily remedied with a heat gun). After dialing in the temp, I then fine tuned the retraction settings (Retraction Length: 1.6mm, Retraction Speed: 70mm/s, Retract on layer change, Wipe while retracting and Retract amount before wipe: 60%) in Prusa Slicer (v2.2.0), and ensured that I enabled 'avoid crossing perimeters' and set the seam position to random. The result was a near flawless, stringless print of the two column stringing test (commonly found on thingiverse). Printing on a stock Prusa i3 MK3 with latest FW. I'm not completely sure if a drop in temp like that is significant enough to affect strength properties; I don't have the equipment to test that, but hey, at least the stringing is taken care of! I hope this helps. Happy Printing!

[@robertavery8897]

I printed a 1x1 x 4 block and adjusted the temp from 260 down on a cr10s pro. .04 nozzle .... adjusted the temp down as it was printing and when I hit 245c. It cleaned right up and stopped stringing and the surface was nice and smooth. Bed temp 60c. No nozzle fan. PETG Pro from MatterHackers in Black .... hope this helps out.

[@OneIdeaTooMany]

I have a permanent reminder on my PEI build surface of how petg likes to weld itself to the build plate. Learned my lesson the hard way.

[@shavewithdave5339]

As a complete 3D printing newbie, I bought a Bambu A1 Mini a few weeks ago, and have printed dozens of models in PET-G with perfect results every time. And I simply selected ‘Generic PET-G’ in Bambu Studio, haven’t changed any settings. It’s fantastic. I don’t think I’ll buy any more PLA (which also prints perfectly BTW) because for me there seems to be no advantage over PET-G.

[@rexroberton810]

I’m going to get a Bambi Lab mini. Are you using the Bambu PETG HF filament? Do you use glue stick or a spray on the bed? One more question, do you use a filament dryer?

[@WilkoVehreke]

Would love to see a PETG tutorial about post processing (glueing, sanding, painting)

[@wingedsword93]

I know there is some good info here and it's a well made video. But dear lord those side burns are distracting as hell.

[@graphene1487]

life is hard isn't it :(

[@robshnob123]

Those aren't side burns...Those are MUTTON CHOPS!

[@ZebraandDonkey]

I have some Avistron German PETG and I am printing it at 217C through a PTFE lined hotend all day long. No problems and it works perfectly. Think it depends on the individual PETG you are printing. Great video as usual. Plus thanks for supporting Joel Telling.

[@Xerber85]

Sonic Alchemy: A maker space - I’m printing at exactly the same temperature (217C) on a Ultimaker 2 extended+, which has a TFM coupler. I don’t get where his ‘need for an all metal hot-end’ advise comes from. I currently use Real Filaments PETG (Dutch brand) on my Ultimaker 2 extended+. It took quite a bit of trial and error to get the right settings since Real Filaments advised 230C - 250C, so that’s the temperature range where I initially started. But now it prints beautiful and strong parts with hardly any stringing. Since PETG has a much narrower temperature band in which it prints right, it indeed pays off to experiment with temperature settings from printer to printer.

[@ZebraandDonkey]

Exactly. It really depends on the printer and space.

[@slkgeothermal]

I am new to 3d printing so I'm open to try different filaments. I have heard a lot of good things about PETG and you have convinced me that I should try it soon. Thank you for a continuing source of 3d knowledge.

[@JayquanDeMarcusWashington]

I just printed my first parts tonight with it and i'm struggling getting it to stick to the bed well. I've been trying all temp options and still struggling...

[@edwinirizarry9277]

Ty so much Alec! You are the first person in my journey to solve this thought in my head . I know this is an older vid but I’ve looked through a few now and no one mentions supports with petg . I am designing something that will need supports and it’s my first print with petg . Besides a Cali cube literally my first . I feared it would weld too well so ty for the air gap info!!!

[@maxx8011]

Nice how you hammer an PLA example with the hammer at already weaker "window" part compared to the PETG thing. PETG is stronger, for sure, but that demonstration was rediculous.

[@colincampbell3679]

and in fact he hit the PLA harder than the PETG one if you watch closely.

[@piratestyleadventures7185]

I have an LK4 longer. It prints aba, and petg very well. 240, 80 bed, painters tape on the glass, little glue stick, make sure you get a good first layer and bam! Strong, glossy, layers well. Time consuming, but pretty good material all around.

[@mt.sinairefuge5360]

I am a newbie printing a MPCNC with PETG on a stock Ende 5 pro. parts are coming out perfect.

[@sergon777]

I got PETG as my first filament for my first 3d printer and I had been wracking my brain on why It didn't work. I then saw an article that said it required higher heat and slower speed to make. Would have saved me some time to research that first. But I guess I can't blame anyone but myself for that one.

[@GMen_3D]

I got my first roll of PETG. This helped a bunch. Thanks!

[@johnkelley9877]

THis was some good information. I am wanting to do 3D printing so this gives me something to think about.

[@grantsorenson]

PETG has not had the thermal resistance I hoped for. I made a door hanger with it and it warped after one day in the summer heat under the sun

[@sejlefrew]

Just got an Ender 3 and was using PET-G as my first ever filament to experiment with and it has been difficult (1st layer difficult to stick/stringing/clogged my extruder once/ruined a would-be successful print because i didn't tighten my nozzle down enough after replacing nozzle allowing filament to extrude from the threads of the hot end). I've ordered some PLA to make life easier, will try the PET-G again once i become more experienced and maybe upgrade to an all metal hot end.

[@TheDementation]

Loved the x-files surprise.

[@sanpedrox2]

No issues whatsoever printing petg on my v6lite @240c. still gonna upgrade to a all metal though, to be able to go higher. Guess it depends on brand, using Addnorth petg. Parts come out perfect and durable

[@trueflightgaming9104]

To be honest, I've been getting the best results with PETG with only 235' at the nozzel. Anything over that and it becomes far too stringy.

[@woophereigo9755]

Hey, my man. This was the best resource after watching about 10 videos about it. Good work, you deserve this space.

[@jonathanpapillo5845]

Great video. I would suggest that you add two things in your recommendations... 1. do you want to print enclosed like ASA or ABS or do you want to print open like PLA and 2. Are there any concerns about nozzle size or does it not matter? Oh, on a more personal note, thanks for the warning about PTFE tubes, I would have made that mistake this weekend without the warning. I will switch to my PEEK lined tube for this weekends experiments.

[@Badwolf914]

Alec, you sir are a life saver. Thank you for all your videos.

[@JheregJAB]

Here I am in 2020 using amazon basics PETG and printing with a PTFE-lined hot end at only 230c. I leave the part fan off, except for bridges where it runs at 40% which is about the minimum for the crappy fan on my printer. The parts aren't super amazing, but they are absolutely serviceable and way harder to break than the same parts I print in PLA. Essentially, I can print finer detail in PLA with less globbing and stringing, but for anything that isn't a fine-detail miniature I use PETG. If I'd print it at .2 or higher layer height, its better in PETG. If I'm printing at lower than .2, its going to matter how tolerant the print will be to blobs or strings... but I still might try in PETG first because its a better material overall IMO. Great tip about the support though, it can be a real PITA to remove, I hadn't considered increasing the gap - seems obvious in hindsight!

[@scarsdale7186]

I run a Capricorn bowden tube on an Ender 3 pro and I print PETG at 240/245 on a powder coated PEI metal bed sheet works fine comes off no problem. I tried an all-metal hotend and it kept clogging I had to buy a cleaning tool that's 1.75mm to clear it after 3 times I went back to the bowden. I had tried the blue tape never would stick to the bed plate it would pull up if the part warped. With the PEI I ran at 80C bed temp solved the warpage.

[@rusanescutraian]

All the video's on KZbin shows ultimakers. But none of them working. Is only a box in the end doing nothing

[@patronza]

I can say with 100% confidence that PETG stuff will not last in the car on a hot day. I made speaker pods and they melted and our outdoor temperature rarely gets above 33 degrees Celsius.

[@helicrashpro]

I thought it was funny that the PETG part broke apart more than the PLA part when hitting it with a hammer. FYI, PETG has really poor impact resistance, at least thats been my experience.

[@KiR_3d]

IMO it was a thin wall.

[@Edyth_Hedd]

It was a very dumb "test" comparison. Pointless.

[@ghulmes8896]

Haha! Yeah, i would have stopped the vid and started again! CUT!!!

[@TheDarazsweb]

I like to use PETG for working parts, but it is not easy to print with. I have thin but dense stringing on the inside of curved surfaces and after time some excess material builds up on the surface of the nozzle. what later on sticks to the printed part . Any suggestions?

[@rondlh20]

Right, nothing about that in the video, strange. I found that lowering the temperature can reduce stringing. Keep the hotend clean, I even added some oil to prevent the PETG to stick to the hotend.

[@fauxbugnl9968]

up your retraction speed and or distance. lowering the nozzle temp will lower your layer adhesion. Which will make the parts weakers thus removing the point of printing petg. Something one can see in this video. That's why you shouldn't let other people read the script that some writes. Especially if they aren't an expert. Which might seem blunt to say, but taking into acount that they're a filament company is quiet funny.

[@markgreco1962]

235 and slower works for me 80mm

[@snaprollinpitts]

thanks Alex!!!

[@johnm.gerard1718]

To add to my post, I am also using the eBox by eSun filament dryer. I use it as a Dryer and a filament holder. Should I still run the Translucent orange Filament though my Food Dehydrator?

[@FranciscoHernandez-fr9kr]

So what setting are you used when your print PETG? Do you leave it in PLA when slicing the object?

[@tykempster]

We print a LOT of PETG, use 270C for better layer adhesion. Essentially no stringing with proper settings.

[@Derekisastro]

It's interesting reading this because it's quite varied what temperatures people claim are "the best for PETG" ... it is quite a large range.

[@drewx10]

My problem with PETG is that there's little knots of the material (buggers) that show up. Some of the little bits look burnt. I'm using a Prusa I3 MK3S.

[@michaelwerth]

PETG from DasFilament (German Company) prints with 235 very well

[@reforgedcriterion1471]

"DasFilament (German Company)" Ya think?

[@Leon-pm6lr]

I use even 240, the package tells 230 +-10C.

[@michaelhipke8394]

@@Leon-pm6lr even with 240 you dont have to worry about ptfe tubing, 240 is really no problem for bowden, what he said in the video is bullshit

[@creamofbotulismsoup9900]

You don't NEED an all metal hotend for PETG, PTFE tubing is generally considered safe up to 250-260C, and frankly most PETG prints fine at 230-240 anyway. If you're concerned with it off gassing even the tiniest amount then I wouldn't print with it above 200C as that is when PTFE begins to off gas...

[@spokoman23]

Question, most PETG I got have to low end of the temp ranges at 220... and it does work. Why so many people say it has to be above 250 C?

[@GerdLPluu]

Different PETGs have very different temperature ranges. Depending on how much G they put in their PET, the material might print well almost at PLA Temperatures and start bubbling at above 240, or it might not even extrude at those temperatures and take 250 to print properly. There are no blanket rules for all PETG filaments.

[@Handleoriginal12]

Overall good video but I felt the need to point one thing out. You can’t do a stress test comparison between PETG and PLA by hitting the PETG lightly on a solid wall and then hitting the PLA harder and on a wall with a hole.

[@zivz.3896]

i've used colorfabb xt on the ultimaker 3 and it took out a piece of the glass

PETG will warp in your car in the summer if you live in AZ. Coming from first-hand experience.

[@exocoetidae667]

Not sure what PETG you're using, but I print mine on a stock Ender 2 with 225 - 235 °C and get perfect results. So far I've tried 'HD-Glass' from FormFutura and the PETG from DasFilament. The HD-Glass's recommended print temperature ranges from 195 - 225 °C and the PETG from DasFilament says 230 +/- 10 °C.

[@arcanum70]

Sorry, but 245 is not the low end for PETG. I print PETG at 235 all the time with zero issues and strong layer adhesion. So, no, you do NOT need an all metal hot end to print PETG.

“Let me hammer PETG:” pow, pow, pow “Now PLA:” POOOWW, PPOOOOOW! POOW! Oddly enough, PLA still resists better 🤣 Only reason to choose PETG is some better resistance to heat (it is not rare to find situations where PLA deforms) and to see some flex before it breaks - PLA will break without any notice. Strength-wise, PLA is stronger.

Desiccant absolutely does pull water out of filament. It's just very slow. If you put it in an airtight container it'll dry out after several days. I've successfully dried nylon with nothing but a Rubbermaid container and some desiccant.

To be fair, if they truly wanted to misrepresent the product they just would have edited that bit out. I would take the hammer test as being as scientific as it appeared. (i.e. not at all)

[@pampacolo]

Whaat? Come on man, the guy is doing you a favor, PETG is tougher than PLA but not as strong in direct impact resistance in few occations, which are due to geometry mostly and you can easly see that the prints are diferent. he's hitting a PETG print that has less material.

[@TravisRamage]

I've been experimenting with PETG on my Ender3...but not too much luck yet. Mainly underextrusion. Been printing at about 250 for the hotend as per the label.

[@ipodtouch470]

Any luck?

[@loganrossignol]

I'm printing a plane wing out of PETG with one perimeter, and it's warping the wing quite a lot. The bed adhesion seems fine, it's just that over time, the poorly supported skin of the wing (it's being printed vertically, so the bottom and top skin of the wing are to the right and left) is bowing inwards between the spars, and the spars themselves are being printed attached to the skin, so as the skin contracts, it's pulling the spars in slightly too, causing the frame to be warped as well. Any thoughts? I've tried printing with an enclosure, lowering the temps from the PrusaSlicer defaults, without really any difference in quality.

[@cinnap1212]

does this setting good for DIY 3d printers?

[@benjaminburtle1107]

In my experience.. thin PETG is brittle. Thicker is very flexible.

[@jeroldmccarty2619]

I just bought the PETG PRO. I bought it because of seeing CNC Kitchens repeated testing showing that PETG will yield before it shatters. MY PETG PRO from Matterhackers SHATTERS when I try to flex a printed sheet of it. I will reach out to customer service.

[@charleschilders2041]

If I use a dry box for PETG will it wick moisture to the rest of the filament? I would like to make a dry box then leave just a small amount outside of the box for access. When I use it I will just cut off a small length before using. I cannot do this if the access length will wick the moisture to the rest of the filament.

Great video. Are you saying that PETG print which breaks is a print temperature issue? Or can this also be a layer hight issue?

[@jdmsll]

[@robertavery8897]

Another note ... I ran into problems with strength and finish with PETG. Didn’t take long after opening the new spool for it to pick up enough moisture to turn the print to crap. Bridle and weak print. So ... I put the roll in the oven at 170 deg F. and then put it on the printer and it printed perfectly. Moisture gone. Here’s the bad part .... next day when the roll totally cooled ... could not get the filament to separate and when I was able to pull it off the roll it snapped like a piece of dry spaghetti... wound up throwing the whole spool out. Don’t do it !!! Keep the temp real low and keep the filament in a sealed bag. Sorry this took to long, but $ 50. for a $3.00 part isn’t smart. Take care.

[@teedjay91]

Everyone is saying PETG has the positive of pla and abs, but its tensile strengh is weaker than PLA, its impact resistance weaker than ABS (it also shatters violently unlike ABS) and I personaly don't think it prints as easy as PLA. But yes it doesn't warp that much and doesn't smell.

[@StuffWithKirby]

It is also heavier. So you get less prints.

[@teedjay91]

[@DonnyAngler]

I'm still pretty new to 3D printing. My problem is likely user error. I have an Ender 5. I have not done any upgrades so everything is stock at the moment. I am having one heck of a time getting PETG to stick to the bed and not to the nozzle. I'm going to pick up some hair spray to try next. I have been trying to print on painters tape and it won't stick to my bed. It keeps sticking to the nozzle. my printer will run a prime down the right side of the bed no problem but as soon as it moves over to my part it just won't stick to the bed. Any tips on how to fix that? I've tried a bunch of different things (different temps, slower speeds, etc.) but I just can't seem to get the first layer to stick to the bed. I'm printing PETG because I'm making custom kayak parts. From what I gather that is one of the better filaments to use for such things.

[@DonnyAngler]

I do keep it in a dry box. I'm going to try and dry it out in the oven. I also picked up a Micro Swiss MK8 Brass Plated Wear Resistant Nozzle to see if that makes a difference. I just got it and have yet to try it.

[@timothyjackson1779]

great vid! please help having problems getting it to stick to the blue tape. It worked on the first run now I can’t get it to stick it just rolls up in a ball. Bed at 90 print at 240. Any ideas?

Try leveling again.

[@ajpapillon7523]

Use elmers glue stick on the blue tape

[@webx135]

"PETG is as easy to print as PLA" "SPeed: Same as PLA" I can get about 17-18mm/s with PLA on a stock Ender 3 v2 hotend with a CHT nozzle. On PETG, I lose layer adhesion at about 9mm/s. For transparent PETG, I lose clarity at anything above 5mm/s 245C on a 70C hot bed. Part fans at minimum. (Fans a max is just so much worse.)

[@WKfpv]

Actually pla is harder than petg. It shatters instead to bend, but the material is harder

petg is weird how itll yeild, but if you chuck a test cube on the ground itll explode.

[@DennisMurphey]

can you say anything about Carbon Fiber PETG I found it a little more forgiving than NylonX, using many of your tips to get some great results. Can either one be annealed after printing to improve heat resistance?

[@Grimmwoldds]

PETG does not anneal. It's PET modified with glycol to prevent crystallization so it stays completely amorphous. This keeps it clear and prevents it from becoming brittle.
