Love PETG, but has a minor drawback. It’s very difficult to glue after printed. Its resistance to solvents is awesome so, no acetone nor chloroform to repair any crack. So make sure your model is well designed beforehand.
@Jorge_Robles I use regular superglue without issues…
Thanks @Rene_Jurack , I also do, but prefer solvent gluing to fix/patch pieces 
what about postprocessing, painting, smoothing?
@Zviad_Sulaberidze I needed to do a primecoating with special plastic primer. I did it via spraybottle. Then normal painting was no problem. Edding (the marker and the glossy paint type, too) does work well, too.
From my experience with upcycling plastic bottles and working with PET sheet materials, I’ve always had issues with glues and paints not properly bonding to them. Maybe the glycol modified PETGs or simply the extra texture on 3D printed parts help here?
There’s a reason why I asked to put ICE PET into the test :). With my small printer that comes without a heated bed, PET seems to be the best option.
I use a ton of PET based materials. EDGE and nGen are my two favorites with just standard PETg base being a good alternative.
I’ve noticed that deburring PET tends to dig in more than debur so a razor blade is my go-to for removing elephants feet or brims
Sanding it works well but it doesn’t smooth out as nice as ABS, but better than PLA.
It does vapor polish in Acetone but not as nicely as ABS.
I’m in the ABS+ camp as my favorite filament. ESUN branded which I find exhibits flawless tolerances. In S3D slicer I set the scaling to 2559 ( I’m a dinosaur using inches ) which equates to 2559/2540=1.007 shrink offset. A caveat however. ESUN Silver ABS+ works great but the same filament in White has defeated me so far. I do print PETG for certain types of mechanical parts. Pretty good stuff and the physical properties mostly beat ABS+ except for stiffness and service temperature. Hard to bond and doesn’t sand etc nearly as well when those things are required.
Great review Thomas … I use 1.75mm PETG a lot and I print directly on aluminium at 75deg and the hotend usually between 225 and 235… E3D V6 and a Bondtech extruder… runs every time flawlessly… I buy for 17 euros per kg …in Europe from http://www.motedis.com/shop/table_cats.php?table_id=18&layer=208
