PETG Filament 1.75mm, 3D Printer Filament PETG Black Bundle, Strong Toughnes, 4 * 1KG(1320M) Filament High Precision, Dimensional Accuracy ±0.02mm, 4 Packs of Black

It seems I get to write the first ever review for this product, woo-hoo! Product is the transparent PETG 2 pack.IMPORTANT: Print this with an enclosure and vent the air outside.//Start: My health experience issues//Before I continue about how the filament prints I want to warn you about the health effects of printing this specific filament. I was about 20 minutes into a print before I noticed a bit of a headache coming on and at the 40 to 50 minute mark my head was not feeling good at all. Whatever they put in this brand/blend/color of filament is the worst I have ever experienced out of any PETG or PLA I have ever printed. After I finished my 2 hour print my whole family all had rip roaring headaches. I have since canceled the other 4 orders of filament I had. still have a 4 pack of blue, red, gray, and orange coming which I could not cancel. I might still test it, but I'm really starting to question if I should.//End: My health experience issues//Now on to how the filament printing experience was. The filament came neatly wound, and sealed up with desiccant and a nice little filament clip in the center of the spool. when printing the filament stuck to both smooth non textured and textured plates very well. The filament itself was dry from the start, good job to who ever was in charge of the moisture. It printed really well with only 20% speed on the fan. Overhangs where nice and crispy. The diameter of the filament was nice and even which really shows when printing tall thin walls. The strength of the prints were great and the flexibility was also good. Overall the print quality was great for PETG. That is if you don't count for the health issues it caused to me and my family. I will try to put some pictures showing the print quality of it at a slightly later date.Update 5/19/2024: Added some pictures of a thin dinosaur cutter using the filament because everything is better with dinosaurs. I will be trying to return this filament because of the health issues is has caused.Update: Added Pictures of the orange filament. All of the colored filament has the same health side effects when anywhere near it during printing. I will be returning the lot of it. And the company reached out to me just to tell me that their product is safe and environmentally friendly twice. And that their people can inhale the stuff just fine. Okay strange flex I guess. As well as giving me my own advice which was to vent the "Odour" if needed. Kinda strange they read my review only to tell me to follow what I wrote in it.

I got this a couple days ago and I have only printed a couple things with it, but so far so good. It came tightly vacuum sealed, prints beautifully, was rolled on the spool nicely, and hasn't clogged my nozzle yet like some other reviews said. I also ordered black and white rolls when I ordered this one, but I haven't gotten them yet. If I don't encounter any issues with the rest of the transparent roll or the black and white rolls, I will definitely purchase this brand again. It seems to be a great filament for the price. I added pictures of the paintbrush stand and the little Family Love momento I printed using it. Both items were found on Thingverse.

This is my go-to black PLA. Super easy to work with and comes out with beautiful, shiny prints.Update 2/23/22I ran out of the first roll that I bought, so naturally after having one of the best experiences I had with a filament, I bought more this month. Yikes. The roll, aside from being mildly tangled, was definitely off spec. The filament shredded the moment it rubbed on any hard surface. At first I thought it was extruder grinding issues, so I adjusted my settings (I tried bring the nozzle away from the bed. I tried slowing the flow, I tried cleaning the nozzle. I tried adjusting the boden tube. etc). But, then I tried 3 other filaments and the problem when away immediately. So I bought another 2 rolls just to see. I had such a good experience with the first roll, I wasn't going to give up on it that quickly--could've just been a bad batch. The next two rolls (one still had the brittleness, the other did not) were so tangled that they stopped going into the feeder just moments after I walked away from the print. The brittleness seems to be on any spool I got that now has the TechBears logo on it. The older spools just had a white label with the printing spec.Now I've got 3 bottoms of a Farfetch'd and 3 bad batches of filament and I'm out $60.I'm heartbroken. Until they start doing better quality control, stay away from this brand of filament.

Printed well on small parts with no problems.Got it at $15 for the 1kg roll which is fantastic.

Unfortunately this filament would either clog my nozzle at too low of a temp(210), and go completely stringy if set at the recommended print temp(230-250). I have a ton of other branded pteg that all printed fine. I cleaned up the extruder and tried an old filament and it went back to printing properly. not usable for me.

Muy buena calidad y por un precio perfecto

It works fine on Bambulab p1p

Tecbears ist mMn auch Sunlu und Sunlu enttäuscht selten. Hier ist die Qualität völlig okay, lässt sich gut drucken und sieht gut aus.
