ZIROPLA Filament 1.75mm, 3D Printer Filament PLA PRO Basic Color Series 1.75mm 1kg (2.2lbs), Dimensional Accuracy +/- 0.03mm, Red

I bought a reel of the blue PLA and was very impressed. So much so that I came back to buy another reel of the same brand but chose black this time. Oh what a mistake that was. There is such a difference its unreal. I'm using ender 3 pro. all standard apart from a glass bed. My temps are 200/65 and had outstanding results with the blue reel. seriously, 10/10 there. Zero complaints. This black reel tho has been a right pain in the rectum. I've tried heaps of different temp settings on the bed and nozzle ranging from 60/190 - 70/225. i cannot seem to find the sweet spot and ive used about a third of the reel in trial and error. Have sent back now and will buy another reel of the blue one. The main issues i face, as you can see from the images, is stringing and not just a bit of stringing, i got ALL of the stringing. I changed pretty much all of the settings i could think of. main ones being retraction and z hop. no cigar. maybe someone with more experience than me will get better results but for me, this is a no go. it did stick to the bed really well tho but bit of a pointless triumph if the rest of the print is going to be horrible.

Absolutely terrible.Bear in mind I’ve been 3D printing for coming up on 5 years so I’ve gone through the paces. It’s been coming up on 2 years since I’ve had either of the two issues I experienced with this filament.I bought two rolls because I’ve got a massive project on the go.The first roll (black) started off fine, then about an hour in I noticed the filament had tangled, locked and caused my Z axis to pull out of alignment.I spent about 8 hours calibrating everything in carefully, for which it printed just fine having sorted the tangles, then decided to instead try the second (cyan) roll.Woe was me, because on the 2nd layer I noticed it was extruding essentially nothing. Cue some swearing and checking extruder gear, hot end etc, came to the conclusion there’s a blockage in the nozzle most likely caused by the brand new reel I just started, but which I still need to cold-pull out as it’s also stopping other filaments printing properly as well.Just seriously, cannot recommend.

I have been printing quite happily with Geeetech filaments which are comparable in cost. The Ziro grey pla filament in contrast is absolute rubbish. It came vacuum packed and all looked good. The spool winding however is awful looked like someone had would it the morning after going out on the town. but the worst part is that I simply cannot use the filamen at all for any prints.. I am using a genuine E3D Titan Extruder and V6 hotend and have put a new nozzle in and no matter what temperatures / feedrates I try for this filament it blocks, its stringy and just will not exit the nozzle cleanly and thus will not adhere. I must have tried at least a dozen times, each time I switch back to another filament and the printer works beautifully. I have another spool of Ziro, black which I will try however the remaining 300 odd metres of this will be going in the bin, very disapointed and will not buy this brand again.Update: I have now had a chance to try the black filament. Again it was very well packaged and sealed and came with the resealable bag. The winding on the black spool was better than the grey. I found the bed adhesion and extrusion to be marginally better on the black but still could not actually get past the first few layers. It may well be that the filament requires a higher temp as some others have suggested however I tried from 190C up to 220C on the hot end as the sticker on the side says and had little success. Overall, really not impressed with the brand, maybe I just had a couple bad rolls as other reviews are mixed however from personal experience I wont be buying this again.

Got 3 rolls of Ziro filament: green, yellow and orange. Yellow is actually quite alright and can't fault it. This is where it goes downhill. Orange is ok but a bit brittle. Green - will never buy it again and because if it, will try to avoid the brand. Other people also report similar stories where some colours are good but others not so much.So green is horrible, mentioned that already. It did clog the nozzle twice. Not had a single clog in 2 years of printing and I (we) print a lot as my wife has a small business that uses 3d prints i.e. we used those 3 rolls in 2 weeks. So yeah, 2 years no clogs and now 2 just on a single roll (more like 2/3) of this thing.Looks like there might perhaps be a cleaning agent/plastic mixed into the filament as it had a way lower melting temp. That on top of other irregularities. On the first clog, I tried to force the filament through by hand and eventually it did go a bit. Basically, it squirted out like it was water and quickly solidified again. Never seen anything like it. The second time it happened again but it was preceded by a lot of oozing goo again and then the extruder gear started slipping due to clogging.Thankfully green was for batches of small parts printed one by one. Not much loss in this case apart from a little bit of time and effort. Would be a different story on a complex multi-day print, can just imagine the frustration of some much time being wasted.As mentioned, not had major issues with the orange and yellow one seems quite ok. However, it seems to be pot luck and therefore can't recommend it. There are a lot of other brands that offer better consistency for the same price. Only bought Ziro as the one I always buy were all out of stock at that moment but had to fulfil a customer order.Will not buy again unless absolutely have to.
