ZIRO 3D Printer Filament PLA PRO 1.75mm Glow in The Dark Color Series 1KG(2.2lbs), Dimensional Accuracy +/- 0.03mm

There were a lot of negative reviews of this stuff, but I decided to give it a shot anyway. I'm very glad I did! Some people say it doesn't glow very well, but you should keep in mind that the material has to be a bit thick so there is enough of it to capture the light in the first place (don't expect a wispy thing to glow very well), and the light source has to be appropriate (it seems that light sources with a reasonable amount of UV in them work very well, such as the sun or a bright LED flashlight).The primary negatives I have to say about this material is that it's got a scratchy texture, which I imagine is not doing great things to my printer nozzle, and it's very brittle. If you use it and you end up breaking pieces off by accident from time to time, don't be surprised, just be careful. It's actually pretty similar to a wood filament in that regard.Pics show Benchy printed at 0.15mm layer height in both normal light and in the dark. Benchy printed basically flawlessly with my printer's default PLA settings.

Great blue glow! Thats the only thing positive I can say about this extremely poor quality filament. I didn't get far with it though, because the spool I received was so twisted it yanked off my filament holder during a print, breaking the spindle and unraveling everywhere. Reached out to customer service but didn't seem to care.In an attempt to salvage some of the roll, I attempted to wind up what I could on another spool only to find out that this was knotted up to an extremely. Taking bits and pieces for smaller prints, trying to salvage what I could after getting stuck with this poor quality product, I then found that the thickness throughout the filament also varies widely, causing jams and poor prints.This is just poor filament, poor quality assurance, and poor customer service. Tons of options out there, avoid this one!

UPDATE: So recently I replaced my hotend, cold end, thermistor, and tuned my temps while reading with secondary thermal scanner, and it turns out this stuff actually prints amazing! I mean Wow! I had no stringing, no extruder skips, no layer separation , nothing, not one issue regarding filament malfunctions... This is actually one of the best filaments I have ever used so far and one thing i really like about it is that It is extremely hard and solid! it glows really really nice as well so i plan to make some kind of led tea light designs and maybe even some parts for my 3D printers My only complaint is no one ever reached out to me to help me resolve my issue but thankfully I figured out what the issue was. If anyone else has issues printing this, get yourself a cheap laser temp sensor or a thermal camera to read the temps on your hotend. Mine was almost 80 degrees Celsius too low!****MY OLD REVIEW IS NO LONGER VALID BUT I WANT TO LEAVE IT FOR OTHERS TO READ IN CASE YOU THINK YOU HAVE SAME ISSUE AND REALIZE NOTHING IS WRONG WITH THE FILAMENT****I read all the 1 star reviews and bought anyways hoping that those people just did not have their printers tuned correctly but it turns out they are legit. I tried the recommended settings of 40mm/s @ the 200c or 220c and even tried everything else but I could hardly get this stuff to print without the extruder motor skipping constantly. I managed to get it to print and it is nothing like what they say for printing instructions on this listing. I had to print at 250c (yes my ptfe tube started melting) at 20mm per second and even then i had to turn down my overall % speed to about 70% just to get it to stop skipping. I made sure I tried everything before I came here to write this but they know what they are selling here. They should be testing some rolls from each batch before they ship them to Amazon because this is scamming us as customers and also hurting their reputation.This product is useless to me and cannot be used unless i want week long prints that should only take a day.

This stuff looks awesome, prints amazing, and glows like a son of a gun...BUTthis required as much fiddling as PETG to get dialed in the first time. it's VERY soft, and the diameter seems to vary. I don't have a measurement device on my filament, so I can't attest to whether the diameter was getting stuck or whether I had the filament tension wrong - but I blew several prints basically finding the printer "printing air" after a while - the extruder drive gear had ground into the filament, formed a U-shape cutout, and ceased to have anything to grab onto to push into the heater.I would definitely give the material another run, and I've plans to add a measurement tool on the feeder soon for exactly this kind of issue.Overall, I'm not ready to rate the material badly - just use with caution - expect at least the woes that come with a softer filament, but if you get prints to come out, they're worth it. Will post photos if I remember to :P

Although troublesome at first once I got it printing right my mind was blown! First of all this is extremely brittle stuff. I had to attach me old filament guide to smooth out the curve too the extruder for fear of it breaking. This is the first time I've had to increase the flow to get it out the nozzle by 4% but hey it worked! Once I fiddled around with the settings whilst watching it print the first few layers I settled at 75% airflow - 104% flow - 220'c hot end - 60'c on glass bed with no adhesive running at 60mms at 0.12mm layer height - 4 walls and 30% infill. It printed a treat, water tight and glows really well. Really really impressed with this stuff.P.S. only expect a few long prints before having to replace the standard brass nozzles this stuff eats brass for breakfast. If using stainless or coated nozzles then there's no problem!

I got some of this filament for a glow in the dark "Jeloseum" sign (for anyone wondering, it's an in-joke from my VRChat friend circle) and it's really cool stuff. So cool in fact that when I modified my printer and changed the extruder to a bowden style with an e3D V6, I printed the carriage mount out of it!So... onto the issues...I had to ramp the temperature up initially as running it too low caused the nozzle to clog very quickly. Running this filament between 210 and 220*c (I recommend 215*c or to ramp it up in 5*c increments). I also found out that running an 0.6mm nozzle helps with clogging a bit and so moved onto a 0.6mm for convenience. It took me quite a few print tests to actually get this stuff to print properly at a sane temperature. Also, this filament, unlike most other PLA is very slightly hygroscopic and it might be an idea to dry it off if you have had it in storage without a dessicant for a few weeks or print in a humid environment like I have to. Not doing so can cause bubbling and missed extrusions if your filament has absorbed sufficient moisture to do so.Besides that, this stuff sticks well to the print bed, looks dope af when you do thin walled prints and can see the supports inside, the diameter is very consistent . Also, as seen in the photos, put a blacklight behind this stuff and it glows like crazy!! It also has a nice afterglow when it's been hit with regular light, although due to the fact it's blue it doesn't last all that long. Maybe a good 10-30 minutes under a regular incandescent light and longer if it's been hit with sunlight. There's a scientific reason why but I won't go into it here.I'd recommend that anyone who's just starting out with 3D printing holds off a little on getting this stuff until they have learned how to properly dial in a print profile for more exotic stuff like this. This filament can be a real pain to tune for initially, but the payoff is huge.I'll definitely be considering getting more when my spool runs out because it's fun to print under the light of a blacklight :)

Great product prints well I have found it best to print around 200-205 deg c and 60deg bed. Print slowly at 50mm and comes out great you can print faster but I found slower gives a better glow. I printed the minecraft lamp at .2mm layers with solid walls and solid base/lid (no infill) and it glows all night long without charging. The first one was printed with 20% infill and 2 walls this did not glow as bright but all three together was still bright enough to light up the bedroom. Ones with poor results it’s most likely due to thin walls/infill. The first print I did was some letters that were quite small only 2 walls thick and 20% infill. The glow was weak and didn’t last very long

I’ve had fun with this filament printing a couple of Halloween decorations. It’s printed really well and glows well. Only thing stopping it being 5 star is that the raw unprinted filament is extremely brittle. Printed items seemed fine. Not sure if I’ve got a degraded role but you can’t bend the raw filament much or it snaps so if you had to manoeuvre your filament through some bends it could be a problem.

This is great PLA! It arrived on time and was well packaged and came with a spare Ziplock bag to store the spool between uses. I am using it with my Wanhao Duplicator i3 Plus which has a Micro Swiss all metal hotend and a heated bed. The best temps I have found for my machine are 210/50 or 210/0 as this PLA does stick to a cold build plate. The glow in the dark part is not as intense as in the pictures and doesn't last that long but is still cool. I highly recommend this PLA.

I was looking specifically for a blue glow in the dark filament and Ziro’s seemed to be pretty much the only option.Was really happy with the results, both from a printability point of view and the actual glow effect. The finished stars are fixed on my son’s bedroom wall, on sunny days they are usually well charged when it gets to bedtime but for those gloomy days we bought a small UV torch which does the job of charging them up just great.Note that phosphorous filaments are abrasive and that they will wear brass nozzles down causing the hole to go oversize and out of shape. I’d advise to use a hardened nozzle

I use Ziro PLA a lot because I get good, repeatable, results. I have glow-in-the-dark green as well as this blue and I have to say that the blue one is nowhere near as good on the glowing front.In a side-by-side test, printed with 75% infill, the green one glows brighter and longer. The blue is almost unnoticeable.If you want a translucent PLA with a faint blue effect, it's great. If you want something to glow in the dark, buy the green one.

Produced some nice prints but having a lump/solid bubble half way into the spool was a nasty surprise. The flaw was sufficient to destroy the print job by jamming the print head requiring disassembly of the extruder/head, 2 days down time waiting for bits and the purchase of said bits. Not happy!

Quite happy, very little shrinkage, glows really well after a quick charge from a 3w uv lamp. Shrink wrap seems to have preserved it well as well as the included dessicant. Includes a bag that you can use to put the roll back in.Ordered a second roll, will see if some of the issues others have had will pop up, but certainly not on the first roll.

Not bad when under black light, not the best filament i have used especially as bed adhesion was not very good. Worked better if you ramp up the temperature of the bed to 70 and the tool to 215

WOW what an amazing product, the blue glow even after extruding on a 3D printer is 1st class.The filament thickness was spot on at 1.75mm.A very good price and will look to buy this product again.

I printed a Lithophane with this filament and it turned out brilliantly. The glow is very bright and looks great. This filament is almost clear when used with thin sections and an off white when used in thicker sections. Incredible results for the price of this filament. The spool itself arrived slightly damaged but not enough to affect the use of this product.

I HAVE TRIED A FEW FILAMENTS BRANDS AND I WILL SAY THIS HAS GOT TO BE ONE OF THE BEST IT'S ALL I USE NOW

Used it to make toys for the kids. Is great watching the kids play with glow in the dark planes with the lights out!!!

Brilliant quality filament, will be ordering more.My settings on CR10 Mini.Noz - 205Bed - 60Retraction - 6/60mm
