ZIRO 3D Printer Filament 1.75mm TPU Flexible Filament 0.8KG Spool, Dimensional Accuracy +/- 0.05mm

I recently converted my CR-10S to direct drive and thought I would finally give TPU a try.I had read a lot of people have trouble printing flexibles and quality is usually not great.I don't think this is quite as flexible as a lot of others out there, but the filament is definitely really floppy, but doesn't actually stretch much.I can print at nearly the same settings I use for PLA, even retraction, without a problem.I will say, on my printer, this tends to like printing on the higher end of the temp range. I print at 230C. Just don't use Z-Hop.Prints are stuff enough to hold their own shape, but flexible enough for objects that need to flex.Great stuff at a crazy good price!

Edit: the first ¾ of the roll printed great. Then I realized it started under extruding. The size went down to 1.50 mm towards the end of the roll. The rest is unusable.I've been printing with flexible filaments for over a year, I've used mainly hatchbox and sainsmart. Hatchbox is issuable my go to but this stuff is just as good. I've seen some people say how the couldn't get it to print right but you really have to find the temperature "sweet spot" just like any new brand of filament. I was surprised I had to run this about 30C hotter than my normal hatchbox tpu (currently printing at 222C for this filament and normally 192C for hatchbox. Love the color and will definitely be getting more in the future.

Pretty decent stuff. I tired it on my big printer with a bowden feed system, no dice. So I can only use my little Anet A8 with this stuff, my other TPU is the same way. This is much softer than other TPU I've used which is what I was hoping for. The Anet A8 eats this stuff no problem. As like my other TPU, I had to slow down my prints to 25mm/s which isn't a big deal. I printed some inserts I designed to turn a large ball bering into a filament spool for my large RAMPS printer. Then I printed a serpentine belt for a large 12T sprocket. This stuff make excellent belts and the spool feeder turned out great too. So to have success with this stuff you need a direct feed extruder (No V6 or the like) and print slow if thing start to jam up, also you may have to disable retraction. But if you need belts, wheels, tank tracks, shock absorbers, anything rubbery then this is the stuff.

A soft white, somewhat translucent, strong, flexible Urethane filament. I've made several things with this filament. I make things freehand using a pen, so this review isn't necessarily relevant to 3D printer users.I've made several little holder belts, like to hold a guitar cord so it doesn't tangle in your gig bag. Power supply cord controllers. This filament is, as I said, tough and flexible and works like a champ for things like this. I made a chuck key holder with it when the original one from DeWalt broke.I've also made a wearable sign with it. I'm going to use it for the foundation for an "I Bite" cape for my Chihuahua so people know not to try to pet her. It's light and flexible enough for a small dog to wear comfortably. I have other colors of the same filament for the letters and symbols.So - I think it's good stuff.

Printing like a charm on a modified CR-10. Running at 220/45, 15mm/s, no retraction, 100% cooling after the second layer, .032mm layer height. I recommend the EZRstruder and capricorn tubing to make it work, though. Not nearly as flexible as ninjaflex, but the tensile strength is Amazing. Using it to make some tires and drive gear belts for a RC Star Wars droid that I am building. They even included an antistatic ziplock back with desiccant to store it, which I thought was a nice touch.

No matter how slow I go with this filament it always looses grip in the extruder.... I have used other tpu filaments with no problems. I have used this ziro filament on both an ender 3 pro and a cr10s pro... Both have failed the same way.... Mid print! Boom! Looses traction! I tried even 5mm for the feed! I'd like to get a refund! Maybe I got a bad batch?

I diverted for a while and came back, this is a semi-flexible filament, I print on my direct drive Prusa I3 knockoff, with a tight pinch feed. I run my hot end at 235C amd my bed at 40C, with elmers purple glue stick on the bed, at 25-30 mm/s, and 0.2-0.3mm layer height, and fan speeds of 75-100% for layer cooling.

*Note! You need a printer capable of printing flexible filaments to get a good result from any flexible. Generally you can modify your own to handle it. Modifying mine cost a few cents worth of PTFE and a printed part. No feed failures in 2 spools.Anyhow, on to this filament. The spool I got prints very well. I've been burned by cheap filaments before, but I rolled the dice and this one is very good. I've only got the one spool to judge so far, but will buy again and hope it's not an anomaly. Also, the creeper pictured printed in three parts, that pic is assembled.

So I printed this tpu with my ender 3 pro,on a glass bed,210°C on the nozzle and 60°C on the glass bed,printing speed 40 mm/s,but I have a good printing profile and a 32 bits board on my printer,the material is flexible,I did try also from Eryone company,I could say they are the same,only a different colour!

Great filament for flexible prints on a CR10-S. I made the extruder drive mod from Thingiverse but I don't think it is really needed.Printing at 20mm/s, 230/70 temps, no retraction.A little stiffer filament which whilst still flexible is great for a bowden tube set up like the CR10-S...

Quite stiff for TPU.

prints well and great colour

Was a bit nervous buying flexible filament as I had heard it required a direct drive extruder (which I don't have). But managed to get good prints on my second attempt, with just a couple tweeks to the print rate and temperature. 👌

great product good prints all the time

When tweaked, it works like a charm!

Great stuff, I use zero all the time

This stuff is great and consistent even with a direct extruder it needs to be printed real slow and hot for best results.Sunlu is the same though and cheaper
