Why is it game-changing? Why is it different from any other filament?
Print with PETG filament and you will see…
My experience with this material is great, better than ABS or PLA…
Faster, easier, no hot bed required, colours,…
Send me a sample and I will!

I have just bought a roll of white PETG a week ago and so far I like it. I did have a hard time getting it to stick to my printbed when no or little heating, so I upped the bedtemp and now it seems to work fine. I am using the following settings and here are my findings so far:
Print temp 240 C
Bed temp 75 C
PETG has no problems with warp
PETG had no problems with shrinking as far as I can tell
PETG printed surfaces
PETG is more flexible than ABS and PLA
PETG seems to have very good layer adhesion seems to be extremely good.
PETG is softer than ABS and much softer than PLA.
PETG is a lousy support material, it sticks very hard
PETG is not as good in bridging as PLA or ABS
So far, my conclusions are that PETG is a good replacement for ABS and it just might completely replace ABS as my choice for parts that need to have good strength and a higher operating temperature than PLA can handle.
Thanks for sharing uour experiences! Very valuable 
I have to agree with the conclusions. I just started printing with PETG yesterday and I can see how it finds a sweet spot between ABS and PLA. The 1.75mm PETG I was printing with last night sticks to the heated bed (maybe a bit too much, I probably need to lower the temperature) and I am seeing none of the warping that I see printing similar parts with ABS. PETG is poly(ethylene terephthalate) - glycol modified. It is 100% amorphous (no zones of short or long range order or crystallinity). PETG is rigid to semi-rigid, is very lightweight, is fully recyclable, resistance to alcohols and solvents, is very strong and impact resistant. Print the same part in PLA and PETG and then compare them in your own impact/damage test - you will find PETG has impact resistance that far exceeds your PLA prints.

Hi William,
Thanks for sharing your finding.
There are some things PETG is not as good in as PLA. Bridging is one of those things. Also, I have had a lot of stringing in objects with thin walls. Perhaps that can be solved with different retraction settings but I am not sure yet.
As for the strength of PLA, if you want a high-performance PLA, you can always get something like Polymax PLA. This is claimed to be up to 9x stronger than standard PLA in impact tests (and better than ABS as well). However, it’s price is also up there as well.
My prints won’t stick. Cold or hot bed 60 degrees. Ultimaker2

Hi,
How fast are you printing.
By now, I have even lowered my bed temp to 60 degrees and have little trouble getting it to stick.
My bed is either with blue tape and a little bit of glue, but lately I have been using a kind of printsticker that is very good in holding on to my prints.
I usually print at 25-45 mm/s depending on the amount of detail and size of the print.
Hope this helps
Printing speed is 50. I’ll try printing at a lower speed. If this won’t work I’ll try the printsticker. Thanx!

At first, printing properties are between PLA and ABS, and it has the best from each other.
-no need for heated bed (but preferred)
-excellent quality on pieces even 0.2mm slice
-no warping, (if you prepare the bed and turn off the fan)
-solid like hell, compared to PLA,
-perfect edges, no curling,
-no need for support for bridges up to 1 cm horizontal.
Here’s my setup (tried many settings, and found this)
Micromake Delta kossel mini printer with auto leveling
235C extruder temp
no heated bed
no cooling fan, only hotend heatsink fan running
Slicer: cura (35mm/s speed - %90 flow for 1.75mm)
You guys mossing one very important point - filament density. PETG is crazy dense: 1.38, while PLA that I almost never use is around 1.25-1.30. While ABS is 1.00 and imo is the best sturdiest material with great qualities such as:
1) easy to sand
2) easy to weld using acetone
3) not prone to cracking (due to being flexible).
I use 3D prints for drones and other things where weight is important, as well as impact resistance. PETG misses the mark over there completely.
I have used PETG for a few days now and am completely in love with it!!
It is very easy to print, the only thing i changed from PLA is the temperature, which now is 220-222 degrees compared to 210.
The speed is no problem, i can print neat and clean at a speed of 65mm/s. same speed as pla.
the strength is much higher you can even feel this trying to bend a PETG print compared to a PLA print.
Would recommend it to everyone considering it!
