SainSmart TPU Filament 1.75 Pink Flexible TPU 3D Printing Filament 1.75 mm 250g Translucent Color Dimensional Accuracy +/- 0.05 mm

Sainsmart TPU has a great feel to it. The filament is tough, flexible, and feels like tire rubber (I'm not sure what durometer this is, but it is a tough, flexible, stretchy plastic). It prints nicely, but you really almost have to dry it to within an inch of its life, and print it straight out of the dryer, or it'll lose adhesion and string like you've never seen filament string before. I had good luck with using the SUNLU filament dryer box S2. It lets you keep the filament dry and print it straight out of the dryer.The test prints were run at a hotend of 228, and PEI bed temperature of 55 (all temps in C, because 3D printing is a communist activity, and printers almost always use centigrade). I had some bed adhesion issues, but those were partly due to the rounded feet on my test model. Supports were somewhat problematic to remove; the plastic was so stretchy that the supports stretched then snapped back while pulling on them. They were eventually removed, and the model looks pretty good (I haven't done any real cleanup on it). I did notice that I had a layer adhesion issue in one of the legs, but that was about where the filament dryer timer had turned off, and I was starting to get stringing.This is great filament, despite being as hygroscopic as a sponge. It prints well, feels nice, and passes the bite test (I am planning to make some toys, and I wanted to make sure I couldn't bite off any pieces - spoiler alert: I couldn't bite off any pieces, despite putting some real force into the attempts). I recommend it enough that I'm buying more of it (and in different colors). This was my first foray into TPU, and it was a great experience overall.

I got a Vibra alarm wristwatch and didn't like the 1 piece holder that doubled as the wristband. It was too small and prone to excess wear and tear. So, I designed a holder to hold the Vibra watch and accept a commercially available watch wristband. I 3D printed the holder from some old TPU that I had, but the aged TPU had gotten a little stiff, and didn't match the wristband well.So I searched for navy blue TPU and found this. I will say that in my opinion, this isn't a true navy blue. My prints look more like a darker medium blue. It's still a good color, mind, but not true navy blue. The wristband I got is navy blue and this filament is a lighter shade, but I'm digressing here.Printing a new holder out of this was a snap and the holder turned out awesome. Aside from being a few shades lighter than the wristband, this filament gave the holder enough flexibility to accept the wristband I installed on it, and hold the Vibra watch very firmly, yet I can still easily pop the Vibra watch out to recharge it as needed.With that project out of the way, I've began printing statues and figurines to practice airbrushing on, and have printed a few turtle figurines from this filament so far. Again, the prints look great.I haven't had tangles or snags on the spool, nor have I had any flow issues. I've printed with this filament through a 0.4, 0.8, and 1.0 mm nozzle and this filament has flowed just fine.I've used this brand of filament in the past with great results, so I didn't have concerns about ordering this. As it's been yet another good spool of filament, I'll keep buying this as I need it!

Works great on my Prusa!I use the Amazon basics tpu profile with a .6mm nozzle.

The box is labeled red but the spool is not labeled for color like other brands. Print quality is fine.edit: looks like there was a mixup in inventory (looks red through the dark window)

I use this to print my GoPro mount for drones and it comes out with great quality and adhesion and doesn't clog as easy it's works great with the stock hotend on the Ender 3/ Ender 3 v2

Let me start off by saying this is my first TPU and I'm fairly new to 3D printing in general. The spool was packaged well and the color is just as I expected. It's flexible but not too elastic. Once printed it can be squishy or very firm depending on your infill settings.The Bulbasaur shown in the photos was my first print and it came out, in my opinion, quite nice. There was very little stringing and only a few little blobs on the top of the print near sharp edges but I'm sure that can be cleared up by further tuning of the print settings.After watching several tutorials on printing TPU and using some of the suggestions posted here, I was able to get this print on my first try.I thought it might also be helpful to others who are new to TPU, or just this filament, if I share my settings below.This was printed on my (2019?) Creality Ender 3 Pro. I do have some modifications (main board upgrade, Marlin 2.0 firmware and modded fan duct) but I don't think those contributed much to the print quality. Everything else on my Ender is stock.Here are the print settings I changed in Cura 4.6.1:Layer Height: 0.175mmInitial Layer Line Width: 150%Infill Density: 5% (you can choose yours based on your needs)Infill Pattern: Gyroid (choose based on your preference)Printing Temperature: 230 °CBuild Plate Temperature: 65 °CFlow: 110%Speed: 15mm/sEnable Retraction: DISABLED (uncheck)Combing Mode: Within InfillCooling: 50%Build Plate Adhesion: SkirtDefinitely make sure your Z offset is adjusted properly to get an ideal amount of squish when the first layers go down so you get good adhesion. I did have to tune and adjust this during the first layer. This is where a skirt or brim is comes in handy.Overall, I'm happy with the product and will be buying more in the future.

First time printing with TPU, gotta say this material prints is really nice. Printed on Bambu Labs P1P at 255/45° at stable speeds. Hardly had any stringy. Really nice color and flexible. Was able to print anti-vibration feet's for my printer and phone case for my S23 Ultra.

Works good in my printer I had to play with my heat settings some to get print good but good material

Super facil de imprimir con las configuraciones adecuadas.

Mi marca de filamento preferido por su calidad y precio, los colores son espectaculares, las impresiones brillantes y limpias

Funciona muy bien para sellos, se comporta eficientemente en el extruder directo de la impresora, sin atascos.

Muy buena calidad, no tuve que calibrar mucho, solo imprimí a temperatura 230 en una Ender 3 Pro y en Cura no hice grandes ajustes. Si lo recomendaría.

Premetto che sono nuovo alla stampa 3D e che posseggo una BambuLab X1C con AMS e un asciuga filamenti SunLu (la versione 2 "aggiornata").Se vi state chiedendo se la marca e la qualità del TPU fanno differenza, la risposta è: sì, la fanno.Con questo TPU, senza nemmeno perdere giorni e notti nella configurazione dei vari settaggi, sono riuscito a stampare tutto quello che volevo. Ho impostato il range di temperatura come raccomandato e poco altro.Sono riuscito a stampare tutto: dai modelli più semplici a quelli che con il TPU SunLu davano problemi di stringing a iosa.Imperativo: asciugare il filamento prima di utilizzarlo.Ma già dal look & feel il filamento si presenta più "gommoso" e robusto di quello SunLu e, a seconda dell'infiil utilizzato, potete avere la robustezza che desiderate.Senza difficoltà, sono riuscito a stampare con flusso e velocità di stampa enormemente superiori rispetto al TPU SunLu.Dirò di più, dopo aver stampato con questo filamento alcuni prototipi riusciti bene, mi sono accorto che in BambuStudio stavo utilizzando uno dei settaggi di default per la mia stampante, che impostava una velocità di movimento dell'estrusore molto più alta rispetto a quella tipicamente consigliata per il TPU.Dirò ancora di più: con la X1C sono persino riuscito a stampare il TPU in modalità sport, cioè con un aumento del 24% della velocità di stampa rispetto allo standard senza notare sbavature, imprecisioni o stringing.A essere sinceri, l'unico stringing che mi porto dietro è quello causato dalla "first layer inspection" della X1C che, come noto, non ha un sistema di pulizia ugello dell'estrusore efficiente al 100%.Nel complesso, se alla fine della stampa mi ritrovo con 2 sottilissimi filamenti che hanno fatto dello stringing è tanto.Se cercate un filamento che vi consenta di essere produttivi subito, questo va considerato assolutamente.
