GIANTARMTPU Filament 1.75mm Flexible Soft 3D Printer Consumables Black,95A 1kg Spool (2.2 lbs.), Dimensional Accuracy +/- 0.05 mm

I am a fan of and normally purchase Bambu filament, but I saw this on 3dprintingdeals for a really good price, so I thought eh, I'll give it a try. I printed out a sample card on my X1C, a habit I have whenever I get a new roll of filament. I am REALLY impressed. I've used TPU a few times before (I always printed it on my Flashforge...hadn't tried it on the X1C until now), and I've always had trouble with it -- stringing, under-extrustion, poor adhesion -- pretty much the gamut of printing issues. But not with this Giantarm TPU. I dried it for about 12 hour and kept it in the dryer while printing, and it came out PERFECTLY. First, the color was beautiful -- it's a very nice blue but it's fairly transparent which I haven't seen from other TPU I've tried. Second, stringing was minimal -- I have never had luck with TPU without a ton of stringing even after drying for long periods. Third, adhesion was perfect (I used the textured plate), and it also came right off the plate without issue. It was just EASY -- something I haven't found with other TPU.I don't normally review filament that I buy but this one kind of amazed me.

Great TPU filament. Has great flexibility which is nice when printing toys for my kiddos (they are young and toys get thrown). I really like this brand, I have had zero issues with the adhesion and the color is pure black which looks awesome. I have already printed out a couple of ducks, and I will need to print out some baby dragon toys for my littlest. Overall I am very satisified and would buy again. Great Price for such a great filament!

UPDATE: Stars changed from 5 to 4. I was so impressed with Black, that I ordered Yellow and Red both of which do not print as well as the Black. I had to change print settings fairly drastically in order to get the red and yellow to print at all. Upon delivery I was able to confirm the red filament, although it appeared to be vacuum sealed, was not. Air had already infiltrated the package before I opened. The Yellow however was sealed tight however both yielded frustrating print results and total failure as it constantly jammed. Visual comparison between the red/yellow and black indicate the black was wound more neatly, and more uniform. The red/yellow had minor twists and turns which help the jamming process in that if it's already bending in one direction it will easily give in that direction when its being pulled and pushed into the extruder resulting in a jam. I've had luck with the following updated settings and unwinding the spool while winding onto a smaller lighter wait spool and completely loosening the feed pressure.Updated settingsTemp: 233Speed: 20mm/sRetraction 1.5mmFan: 50%ORIGINAL REVIEW:Spool was vacuum sealed upon delivery. I was skeptical having not used this brand or having ever printed with TPU in the past as I had great success Flexible PLA in all colors but black. After reading and combining recommended settings from multiple forums, I had a perfect print right out of the gate without glue on a flexible course metal bed.Sovol SV04 Settings in Cura 5.4.0Layer Height .15mmCross Infill 30%Nozzle Temp 220cBuild Plate Temp 56cPrint Speed 30mm/sTravel Speed 120mmInitial Layer Speed 20mm/sInitial Layer Travel Speed 80mm/sRetraction OnRetraction Distance 2.0mmRestration Speed 20mm/sRetraction Extra Prime Amount 1.0mmRetraction Min Travel .8mmMax Retraction Count 10000Max Comb Distance with No Retract 10mmFan Speed 100%Initial Fan Speed 0%Regular Speed Layer 2Good luck!

It took some trial and error and finding some helpful information online but I am now consistently getting great bendy and squishy prints from this filament. Dry the filament thoroughly, lower infill density means more squish, print with a hot nozzle on a cool PEI plate, and print slowly -- those are the key bits. The filament size and color have been consistent and I've never run into a knot. This filament is a great value.

I liked the prints I made with this filament. It can be a little stringy but adjusting the print settings can help to minimize that. I did not experience tangling, clogs, or other problems.

Alright—printing TPU is not like printing PLA. It squishes, it stretches, and it’ll jam a Bowden setup if you breathe wrong. But once you’ve got it dialed in? This filament is a beast. The 95A shore hardness gives you a perfect balance: still bendy and compressible, but rigid enough to hold form. Think tire tread feel, not gummy worm.I ran a full spool of this in a direct drive Ender 3 (with a dual gear extruder + Capricorn tube), and got consistently clean prints at 215°C hotend / 60°C bed. Slightly slower print speeds (20–30mm/s) gave best results. It adheres well to PEI and glass alike, and zero warping on medium-sized prints.

It came tangled like I saw with other people but as soon as I printed a benchy it clogged my nozzle but the benchy had great quality so yea

I didn't really know what to expect with this, but I've been printing it with a profile meant for generic silk PLA, and it has consistently produced great prints. I'd say it's good value, especially when on sale.The only actual issue I've had with it is that it seems to melt a bit differently than other filaments I use, leaving thicker clumps when purging than what I'm used to, and this has lead to large chunks of it getting stuck by my nozzle wiper a couple of times.
