GIANTARM TPU Filament 1.75mm 1Kg(2.2lbs), Clear Filament TPU, 95A Flexible 3D Printer Filament with High Elasticity, ±0.03mm Accuracy, Neatly Wound & Moistureproof, Non-Clogging, TPU Clear

I printed these with the Bambu X1C, with food dehydrator for about 128 F for 24h. A temp tower led to 220 to print. After the temp test, did flow dynamic and flow rate calibrations. It was printed from a filament dehydrator set at 55, though often i forgot to turn it back on. This was my second project with TPU, so I'm not too familiar, though I did read up on basic. I printed TPU Lattice Structure, Gyroid pad, tpu infinity cubes, and croc shoes. You can find these files on makerworld. The TPU infinity cubes was printed on JUUPINE's PEY plate. The rest were printed on Bambu Textured plate. I had no major issues with these print, as they had good adhesion. The blue is a nice pretty colors. I did have stringing issues, but that is expected with TPU, and If I had more experienced, I could have fine tuned it more. The Lattice Structure went perfect, but was string, most went away after using hairdryer. It was a bit difficult to remove form plate with the brim. I should have tested without brim. Gyroid pad came out perfect. Infinity cube had rough corners, which lead me to investigate latter. Printing the croc shoes, it went mostly fine, with expected stringing. it did have rough spots as you can see. It not good as actual crocs which feels a bit softer. the side hole was a bit of annoyance clean out though. I decided to investigate the infinity cube, wondering if it was the infinity file. I tried all 3 infinity cube files, and notice common issues where the edges were very rough. I realized this is due to not doing a retraction test. The default Bambu TPU retraction is 0.4 mm. I ended up using 0.7 mm with some improvement, which you can see in that image with 2 infinity cubes [1 being 0.4 mm and 2 being 0.7 mm], with some improvements. Remember to do ALL your basic filament calibrations. Retraction test would have made my prints way better. I'm not sure about print speed, as was told it is recommended to slow it down for TPU, but I'm not sure if that made a difference. I would recommend GIANTARM TPU, it is ease to use, fun to play with. The blue Color is very pretty. REMEMBER TO DO RETRACTION CALIBRATION. remember heat gun / hair dryer would help for cleaning up most stringing.

This is the first time I've ever used TPU and I was a bit concerned that I was going to have issues with it, but it wasn't as worrisome as I thought and I'm fairly certain this filament is part of the reason why. For reference I'm printing on a Qidi imate-S with a .6 mm nozzle on a 60 degree heated glass bed with an enclosure, top off but sides closed up. I started out with a phone case trying the settings used in the listing, and while it printed "okay" it wasn't fabulous. So I tried another one with settings that I found in a Qidi user group. Again, "okay" but not great. So I scrapped the settings and set them to the default TPU setting in the slicer and tried a simpler print - a snowflake ornament. It came out PERFECT. So nice; no stringing no warping. Just beautiful. So I thought, back to the a phone case. The third attempt was way better than the first two. Still not without some flaws, but usable for sure. Bridging the button holes with supports was a bit rough, the sides turned out good, the bottom speaker and cable holes weren't as nice, but they pass muster. Still have some dialing in to do obviously, but considering I went from meh to really good in a day with a tricky filament the first time using it, I give this filament an A+. The adhesion was really good on the smaller print, and while the phone case didn't come up it did seem to have some marring on the first layer that suggest that it didn't fully stick in all places. So you may need additional adhesive or play with your bed temps when using this. I've heard that TPU is very hygroscopic we've had it out for over 27 hours on the printer and noticed only very slight stringing by the end of that time. Our house is really dry though and not humid, so I imagine that others may see the moisture absorption sooner than that. I highly recommend GIANTARM TPU filament for anyone looking to explore the versatile world of flexible 3D printing. It's definitely a great TPU for beginners to start with as it didn't frustrate too much to try and get the settings dialed in and we did get usable prints within the first day of working with it.

I love this stuff! I have printed a lot of drone accessories with this spool, print quality is consistently solid. I am using the "generic TPU" settings on my BambuLabs A1 through the non-AMS spool holder and I have not had a single feed issue. Print stringing is not too bad at all, nothing atypical. Printed part flexibility is great, durability has been amazing, even when I am tugging on stubborn supports! I have printed an assortment of guards and landing feet and camera mounts and antenna mounts that have held up to some gnarly crashes with zero damage. This color is BRIGHT, which is great for helping spot a drone that you have crashed. I have had zero layer or bed adhesion problems. When this is gone, I'll order more of it, and I plan to check out the other colors they offer as well. It is great to print parts that I can use for their intended purpose (essentially, crash protection!) without worrying about the filament's ability to print a nice looking, functional part.

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 settings Temp: 233 Speed: 20mm/s Retraction 1.5mm Fan: 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.

I’m really impressed with the GIANTARM TPU filament! The flexibility is exactly what I needed for my prints—strong yet soft with just the right amount of give. The dimensional accuracy is spot on, and I haven’t had any clogging or feeding issues on my printer. Prints come out clean, consistent, and with a nice smooth finish in black. This spool has been very reliable, and the material handles well even on longer prints. It’s perfect for phone cases, gaskets, grips, or anything that needs durability with flexibility. Excellent quality, great value for the price—definitely my go-to TPU!

Giantarm honestly makes a terrible product. I've gone through so many spools and literally thrown 90% of the prints out due to failure. The main issue is how they spool the filament. They don't spool it neat and tight, it's messy all over the place. Since it's so messy the filament has almost a memory of every little kink in the filament. Once that kink hits the extruder, she jams right at the drive. Over and over and over again. I've literally sent back spools of this crap. Giantarm has definitely been the worst product I've used since I've started printing. 10+ hour prints...good luck. Great color, prints great if you can get this crap to print. Do not start a print with this and leave for the day

No stringing, seems to be a quality product.Would purchase again.

I do a lot of printing with different filaments, mostly utility prints and combat robot parts, so I am always looking for budget friendly options that can hang with the "big dogs". Rather than just posting more pics of my robots, I printed several non-robot test prints to see how well this stuff compares with other brands of TPU. I used the "Generic TPU" profile in Creality slicer on one of my stock K1 printers, and used the stock layers, walls settings, but I did change infill percentage and type... for a squishier texture, I set the infil to 10% and used gyroid pattern... gyroid looks really good through the sides with the transparent color. I love that it prints perfectly with the stock profile, it will work well for beginners. The filament was even easy to load through the reverse-bowden setup of the K1... just need to remember to get a good diagonal cut on the end so it will slide through the run-out sensor... but you need to do that for any filament, any time you change the roll. I tried pulling the tread print apart both against and with the layer lines... it fuses really well with itself and retains it's shape well. I had no issues with clogging, i printed the braille chicklets in a random orange PLA after the other prints. (it's 3D Printy's model) Compared to other brands like Ninja and Duramic, this TPU holds it's own. I really love the ease of printing. 10/10. I would recommend this even for a beginner with a printer like the K1.

Die Qualität des aus diesem Filament gedruckten Materials ist einfach hervorragend. Es fließt sanft und gleichmäßig durch meinen 3D-Drucker, ohne jegliche Probleme. Die gedruckten Objekte überzeugen mit ihrer makellosen Oberfläche, klaren Linien und erstaunlichen Details. Was dieses Filament wirklich auszeichnet, ist der seidige Glanz, den es den Objekten verleiht.

J'ai commander 2 rouleau tpu de GiantArm. 1 noir et 1 vert. Les 2 arrivées pas scellées aucun vaccum... C'est très midiocre comme qualité. Depuis quand c'est pas scellé...aucune idée... Bref je suis réellement décu de GiantArm.

Première commande de cette marque et j'en suis plus que satisfait ! La couleur est magnifique, la qualité d'impression et top et l'adhésion au plateau est impressionnante. Je vous recommande largement ce PLA
