PLA 3D Printer Filament, 4KG PLA Filament 1.75mm, Neatly Wound 3D Printing Filament, Dimensional Accuracy +/- 0.02 mm,1 Kg Per Spool, Pack of 4, Black+White+Blue+Red

Works great for my 3D class. Students go through a lot of filament, and this package works great.

Pink color and Filament quality is on point! Fast delivery! Printed at 200 print speed! I had customer requests for pink badge holders. I will buy again.

I use this for prototyping projects. It works pretty good. No filament jams at all. The prints are pretty descent quality. I have had no issues using this. I run this at 200 degrees and my prints come out great. I will and have bought again. I like the 4 pack. Good price and the quality is there.

For years I've been using Prusament Galaxy Black - amazing quality and beautiful color - but prices have gotten out of hand and the speckled color has a weird tendency to clog nozzles, even on my Prusa Mk2.5S. So last year I decided it was time for a change. The TecBears specs sure sounded comparable to Prusament, and the price was amazing, so I ordered a roll of black PLA. From the very first print, it was amazing. This PLA stuck to my Prusa's PEI sheet like glue, and I never had a single failed print the entire roll. Also notable is that the roll was wound perfectly just like a Prusament spool. For less than half the price of a Prusament roll, I was in love.So I just finished that roll and immediately ordered 3 more TecBears. The black PLA prices were even lower than I remembered (nice!) so I ordered 2 black PLA rolls plus a yellow PLA roll. I tried the yellow first, and noticed immediately that it didn't seem to adhere to the bed as well as the black. I figured the color pigments were a factor and didn't worry about it too much, and though I had a couple bed adhesion failures, ultimately I was able to get some good prints.Next I tried the black. The first thing I noticed it that it wasn't wound nicely at all - is this even the same stuff? And print after print was just failure after failure - this wouldn't stick to my PEI sheet at all! In the past, I've discovered that once PLA absorbs too much moisture it won't stick (which is why I built a filament dry-box and often use a high-quality food dehydrator to keep my filaments dry and printing well) and I suspected that quality control at the factory was lacking and that even as nicely vacuum sealed as the spool arrived, that the PLA had too much moisture. So I ran it through my dehydrator overnight, sure that would solve the problem. This morning I tried printing again, and still it won't stick. It's almost like the filament is contaminated with some oils that are preventing it from sticking to the PEI sheet.Test after test, I finally discovered that if I slow down my first layer print speed I can get this to stick. How slow? 25% of typical 1st layer speed, which is already <50% of normal layer speed. The actual number is 5mms. That's slow enough that I was able to write this entire review in less time than my first layer has been printing. So it's usable, but what a pain. And what a disappointment after that first roll from last August was essentially perfect.And in the hopes that TecBears actually reviews these reviews, my perfect black PLA spool from August has a label with part # 08101011, S/N: 0610004251Z. The really bad black PLA spool I'm printing with now does not have either a part # or S/N on the spool itself and has a different temp range (190-230 instead of 200-230... again, is this even the same stuff?) while the box has barcode X002DQDG0L, but that's been covered up by a new barcode label LPN RR AS621 1761 (suspicious!). Oddly, the 2nd TecBears black PLA spool I ordered is box barcode X002DQF5YL, so different yet again, but the spool inside looks identical to the bad spool I'm printing with now - well, except this spool's bag has lost the vacuum so I'm looking forward to moisture issues. I haven't printed with it yet, so no idea if it will adhere or not.I'm not sure if I'll ever order TecBears again. I dont' know if it's a lottery and I just got a bad batch, or if these quality issues are here to stay. Even at these cheap-as-plastic prices, I'm just not sure it's worth the risk. That said, after slowing down my 1st layer speed to 5mms, the prints are coming out okay - layer to layer adhesion is fine and surface finish is okay. Had this been the first TecBears roll I'd ever purchased, I wouldn't have written this review I just would have never considered them again. But knowing how perfect that first roll was, it's hard to walk away...EDIT 4/13/2021: My experience has changed, and I felt the need to update this review.After writing the initial review, I discovered that on larger prints the adhesion was failing and print edges were lifting, warping, and ruining the print. I also tried my 2nd black roll to the exact same result. I was planning to come here and take another star off, from 3 to 2 stars, since the yellow was still working okay for me.I went back to Prusament black PLA, and while bed adhesion was remarkably better, the infamous clogs were back. I spent weeks troubleshooting the issue, and rebuilt the entire extruder + hotend, switched to a new PEI surface, and added cooling to my extruder stepper motor. Notably, I discovered that my nozzle wasn't fully tight during all my troubleshooting. Prusament clogging continues, especially with low feed rates at tiny layer heights, and this seems to be a common complaint on Prusament PLA - common enough that I don't think I'll buy Prusament PLA again.Out of curiosity, I tried my TecBears black PLA again, and shock of all shocks, it is working great now. I'm back to default temps and speeds, 1st layer adhesion is good, and I'm getting all successful prints. I've been able to print more in the last few days than I have in months, and for the for time in a while I can just let it print and not have to constantly monitor for adhesion issues or clogging. At this point, I'm attributing my issues to insufficient nozzle temps due to an improperly tightened nozzle. I think the reason this started after changing spools from my original TecBears black PLA (which was a 5-star spool!) to the spools from my 2nd purchase is that the PLA formula was changed by TecBears (different temps, different winding), which exposed an underlying hardware issue that didn't affect the first spool.For this reason, I'm adding a star to the rating, bringing it to 4 stars. This value filament still isn't a 5-star filament, primarily due to the sloppy winding on the spool.

Fast shipping and good quality!

I always fall for the cheap filament adverts on here, but this takes the cake in being the most obnoxious. Nothing is consistent in this filament: from shrinkage to material width. At first, I thought I might have been having an off day, so I tried through an array of parameters. As soon as I had a half decent test come out, the nozzle would clog. I bought the regular PLA, so my expectations weren't that high, but wow did this just obliterate my least expectations.[DIAMETER CONSISTANCY] There is about a 7% (0.122mm) max deviation from 1.75mm that I have found accross the filament, which is a nuisance in its self, but there weren't too many signs of this during the print, more so everything else was much more prominent[EXTRUSION] I never had anything clog my nozzle, and I always purge my extrusion system when changing materials. This filament still manages to get jammed and clogg everything up to the point where I have to yank it out, or worse, take the entire nozzle assembly apart and deal with it from there. At least it didn't come hydrolocked with water. It also doesn't like reacting with acetone at all: for better or for worse.[SHRINKAGE] On the off chance I got a .5" block to print ( I got a few), I got a 2%-5% shrinkage all with the same settings in an enclosure. The blocks were all cool and uniform (with a possible deviation for a couple hundredths), so I must credit that, but this is unacceptable.[ADHESION] Adhesion with this filament is a joke. It does not know the definition, as it wont stick to a heated Borosilicate, or heated acrylic bed. I've tried everything from hairspray, to bear, freshly scraped glass, and not even a raft wants to stick.[CONCLUSION] The hardest part was just ruling out human error and unclogging my printer. After shuffling through and comparing this to Overture and eSun, I have ruled that this is just awful filament. At least now I can have time to clean out my nozzle and heating block while I wait for another roll of pla to come in from eSun.

Arrived fast and great quality will order again

I've bought 4-5 rolls of Tecbear PLA and they've all been great, clean smooth prints, but they grey PLA had jammed up 2 different printers with a section of unmeltable of filament. Even at 300° the filament is just jammed into the hotend requiring dismantling the extruder to remove the hard section
