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

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.

Worked out great on a Bambu mini at 80c bed temp and 250c nozzle temp. This was after my first failed attempt. Print speed must be slow for best results, currently at 30mms. All this with a dryer that feeds it while dryer will definitely yield best results.If you are having issues, clean your bed with Dawn dish soap or alcohol 91%.This combination worked for me. Definitely buying more.

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 bought this after watching some youtube video's talking about PCTG and its crazy layer adhesion and for work I design a lot of light duty parts that I have to always struggle to orient for print strength with PRO PLA or PETG. I thought this would be the solution. My first print on my Prusa MK3s+ was a bracket for some air lines and it printed with some warping at 260 hotend and 90 on the bed. I cleaned the bed better added some more tabs and a brim to help with adhesion because sometimes even PETG warps on the bed depending on models. Printed 2 more at a time this time same settings and half way through the nozzle clogged and came out of it and partially printed the 2nd half of the print. I changed the nozzle and thought it was an old nozzle I had been running for awhile so I knew they just wore. I then tried the print again this time I dried the filament overnight in my filament dryer to ensure that the filament was fully dry still. I started the print this time and about 30% into the print the nozzle plugged again this time I caught it as the extruder was clicking grinding the filament. I changed the nozzle and decided to print this in my PRO PLA I use as it didn't need the temperature resistance of the PCTG. I wanted to run the same model so I sliced the same model to ensure it was not an issue with the model and just adjusted the settings to print it in PRO PLA. The model printed flawlessly and I had no nozzle clogs as I was unsure if I had an issue with the heatbreak or nozzle seating on the printer but I have since printed about 4 more models with PLA and PETG and have yet to have another nozzle clog. I am not sure if I am doing something wrong but I am following the temps listed on the filament and it prints nice where it prints good but I keep getting the random nozzle clogs from it.
