3D BEST-Q PCTG Clear 1.75MM 3D Printer Filament, N.W. 1KG, Higher Hardness Than Petg，Withstand 100C (Transparent)

best filament i've ever used, bar none. not too hard to print (250c/70c), sticks easily to PEI with some glue, tough with some flexibility making it more resilient than my PC, cheap, foodsafe, and can ACTUALLY withstand 100C! I made parts with it for my espresso machine, it didnt warp under 9 bars of pressure under boiling water. no plastic taste imparted, or smell. I even put a heat gun to it and it held up really well. it's like it's pre-annealed. i'm stockpiling this, only problem is soaks moisture like a sponge.

I've used another high quality clear PCTG in the past that costs a lot more, and there is no difference between these two in ease of printability, etc. using the same temperatures. I use it with a BAMBU printer at the recommended temperatures. No clogs, adhesion problems, or stringing, and the supports break out just as easily. The winding isn't perfect but has not caused any problems at all for me. It was boxed and vacuum-sealed with a small desiccant pack. Will definitely purchase this again (and again). As someone else mentioned, it would be great if the color availability was expanded in the future.

I have had a bit of trouble getting this filament dialed in. I have no issues with pla or petg but the pctg is a beast unto its own. It requires a hotter nozzle temp than petg and sticks like mad to my G10 build surface. But can easily print at high speed pla levels of 90mm/s and still produce high quality parts. My only problem with this filament is it is too thin. When I first started using it something was just off about it when feeding it to the extruder. Just felt too thin. Took some measurements and sure enough it is. Diameter varies from 1.5 to 1.6mm not the standard 1.7mm size as advertised. I tested this on about 50 meters of length and it remained the same size. This resulted in having to adjust the tension on my extruder as well as increase the flow rate a little bit to compensate. Something that the vendor has to address.Overall this filament is just okay, not any better than pctg or pla for printing with.

Took a stab at this.. someone mentioned it on a FB group I`m in.Great filament.. not had any issues.. Mind you.. I keep my rolls in vacuum bags with decadent inside.So I`m always ready to go. Prints nice and no issues so far.

Was pretty excited to get a spool of this stuff. PCTG is a material with so much potential and can be a bit tricky to find sometimes (though it is becoming more popular)However this spool couldn’t be more of a dud. Tangled and brittle, this stuff didn’t stand much of a chance. I kept trying and trying and I’m not new to printing so I had faith I could figure it out - but even on the occasions I could get a good print out of it - it’s just brittle. And I don’t mean layer adhesion splitting type of brittle, it actually had decent layer adhesion, it was just brittle.Now this is odd for PCTG, it’s often renown for its incredible impact resistance as well. Not the case here however. Any good proper prints I could get with this stuff was just as brittle as stock PLA, probably even outclassed by PLA+. Again, not layer adhesion, it shatters across the whole print in all directions under any noteworthy impact.As well as the headache of a tangled spool, this batch just wasn’t a winner. So naturally I want to call it just a bit of bad luck and go to just get a replacement. Nope. Out of stock for another month, with the possibility of never even being restocked at all.So forget it I guess, only PCTG on Amazon that isn’t massively overpriced is probably dead.

I just tried this out last night, printing these fold-flat, print-in-place phone stands, from BambuLabs MakerWorld. First tried with BambuLabs default Generic PCTG settings, which is 250 degree nozzle, 50 degree bed. And I used MagiGoo bed adhesive. Both of the Benchy's printed fine, up until they came loose and then was just a big tangle. That was with reapplying Magigoo between them, and turning the heat up on nozzles and bed. I also dried the filament for an hour or so, though came well vacuum packed.So I turned up the nozzle heat to 265C 1st layer and 255C subsequent, and the bed to 65 or 70, and used plain old Amazon purple glue stick again. Printed great then, stuck well, and not hard to get off with metal spatula.I only gave 4 stars because there is little info on the filament. And no company website. Apparently they only sell through 2nd parties. But satisfied so far

I tried this a year ago on my Ender 3. It printed but it was a struggle and everything curled up. I recently upgraded to the Flashforge Adventure 5M and decided to give it another go. This year-old filament just sitting on my closet floor printed flawlessly. I do have an enclosure so that may have helped. I printed with 90c bed and 260c hotend.I made a shade for my candle warmer and it sits directly on the hot glass and hasn't warped at all.
