PETG filament comparison

My grandson wanted for his first beer party some can holders and I found one
500ml±+my+beer.3mf (1,6 MB)

I wanted to print with several PETG types and colors, to test myself the differences and on the other hand to have for everyone a special one.
I also wanted to test the relative new feature in CP6 to use variable nozzle temperature for different flow rates because the high speed filaments from Elegoo, SUNLU and eSUN all propose different temperatures for different print speeds (see below what I used).

I used for all the above print profile, just changed filament profile for the respective print

The filaments I used(always from left to right):

Now about the filaments:

  • extrudr all very nice! I buy them mainly in batches on their holiday sales or black fridays where they are 20-40% cheaper. The normal silver PETG is normally 39€/incl 20% sales tax but has a 1.1kg spool but I bought it with 40% discount which is then acceptable.
  • Elegoo is my default and I have some 6 other colors from them as well because I by them in packages of 4 for 50€ incl. 20% sales tax here.
  • Flashforge is very nice and somehow nearly silk like color changing, I have also som PETG-CF from them…
  • Kexcelled is not so easy/nice to print and has most problems with overhangs (need to adjust again the print profile)
  • SUNLU (this seems to be the same filament like sold by Bamboo for PETG High Speed) is somehow a PETG/PLA+ mixture, more brittle and less bending than all others.
  • eSUN I bought because I of gold color but it is rather yellow, so I was a bit upset on that and it does not print so nicely than Elegoo.

Unluckily extrudr did not have the gold and copper versions on stock which I ordered and I could not include them in the test.

Aside of these 8 colors I have another 8 colors of Elegoo/esaun and, the Kexcelled PETG-CF (black) and the Tinmorry PETG GF (white) which but will not print more models unless there is further demand.

My PETG prints all have raised Z-Offset of 0.025mm.

You see below (Elegoo & eSun) areas with flat support which were removed easily for all prints.

I forgot also to clean print plate after I printed before some PLA which resulted in some residues on the first print:

I use Ethylacetat to clean off PLA (or remove a bit of layer lines of PLA)

I’m just running a temperature tower on some Extrudr white PETG. Need it for an application where I want better anti-UV (yellowing) than I think PLAs could provide. Even on my K2+ this will be a multi-part project, also a multi-reel project so consistency from print to print and reel to reel will be important. I’m glad I (by sheer chance) have gone with the filament you seem to recommend…

Thank you for the info.

PS Extrudr reels are like a work of art - a symphony in acrylic. It seems a shame to just bin them…but they don’t appear reusable in any way. Am I missing something?

I received today the last missing order of PETG, part of it was also extrudr’s copper PETG and I could finally print the last parts like the beer dispenser for the fridge.

p.s.: Yes, these spools are a bit old-fashioned but in Austria (where extrudr main factory is) they have recycling of hard plastic since years and can return them to the recycling points.

They have also XPETG REC made of recycled material and it is on a cardboard spool!

That copper is niiiiice…

Yes, I agree, it looks like something would like to use.

Here are some new entries in my PETG collection:

The bird nest front is Overture ‘White Rock’ filament, the ‘sky blue’ is high speed matte from YAJO and the black one is matte high speed from SUNLU.
SUNLU & YAJO is actually the same filament, it’s only other brand and packaging. The SUNLU spool came on cardboard with 1kg and the YAJO on a plastic spool with 1.1 kg filament, interestingly this spool is smaller and in CFS not reaching the ‘top pushdown guides’, but it works nicely and they are the most silent spools in CFS I ever had!
Also interesting is that both SUNLU/YAJO matte PETG added the same silica bags and filament clips and I print them even with the same profile which I derived from Creality Hyper PETG and set the max flow rate to 30 mm³/s with variable temperature from 245-275 depending on speed.
The Overture is a normal PETG and prints much slower at max 16mm³/s and I paid ~19€ incl. 20% sales tax on Amazon.
The SUNLU & YAJO cost ~16€ but the YAJO has 1.1kg and is therefore a bit cheaper.

I bought already some other matte HS PETG from YAJO and will use it whenever the needed colors are available.
By the way, the black and the bird nest part were printed standing up from print bed, not lying flat on bed!
All parts are shown as they came off from printer without any post processing.
