TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics which prints strong parts that are also flexible

Compatible with all FDM printers on the market which accept 1.75 mm filament; Including SainSmart INFI-20 Belt 3D Printer, Prusa i3, Monoprice MakerSelect, SainSmart xCreality, and other RepRap printers

With proper settings, TPU is easy to print thanks to excellent bed adhesion and the filament’s tendency to not warp

Great for a variety of projects, such as shoe insoles, watch bands, phone cases, drone parts and more.

Why Choose SainSmart TPU?

SainSmart TPU gains popularity among 3D Printing community for its balance of rigidity and flexibility. In addition, with a 95A Shore Hardness and improved bed adhesion, it is easier to print even with a stock elementary 3D Printer like the Creality Ender 3 S1 PRO. SainSmart TPU will not disappoint if you are looking for flexible filament. From drone parts, phone cases, to small toys, all can be printed with ease.

Printing Tips

  • A consistent and slow feed rate is key to successful printing with TPU.
  • As a hygroscopic material, TPU absorbs moisture easily, drying the filament before printing allows for a smooth finish.
  • Printing TPU Filament with a direct drive extruder is recommended, though it is possible to print with a Bowden extruder, it requires more tweaking.

New Product Design

Our TPU Filaments will be greeting you with its brand new look starting from Early March, 2021. This transition to new packaging will occur over a number of months. During this transitional period, the filaments you received may contain a mixture of current and new packaging. There are no major changes to these products, and the print quality remains the same.

  • Filament Diameter: 1.75 mm
  • Weight: 800g /1.76lb
  • Dimensional Accuracy: +/- 0.05 mm
  • Extruder Temp: 200°C -220°C
  • Bed Temp: 40°C-60°C
Recommended Printer Settings
  • Print Nozzle: 0.4 – 0.8 mm
  • Extruder Temperature: 195 – 230 oC
  • Print Bed Temperature: 40 – 60 oC
  • Cooling Fan: On
Printing Tips For Bowden Drive Printers
  • Print Slower: 15 – 30 mm/s
  • First Layer Settings: 100% Height. 150% Width, 50% Speed
  • Disable Retraction: Should reduce oozing and string
  • Cooling Fan: On after the first layer
  • Increase Multiplier: 1.1, should increase bonding
  • Do not over extrude filament when loading. As soon as the filament starts protruding from the nozzle, stop. Loading any faster will cause the filament to get caught in extruder gear.
  • Feed the filament directly to the extruder, and not through the feeder tube. This reduces back tension in the filament as well as drag, ensuring proper feeding.

If it’s Good Enough.

This is the same filament that Joshua Bardwell uses, if it’s good enough for him and his quads, it’s good enough for me. Nuff said.

Surprising Filament

I was surprised by the filament. I used it to create 'ear savers', the device that attaches to the strings of a face mask and stops them from pulling on your ears. This filament was very flexible, almost like rubber. Yet it seems to be very strong. It takes the stress of the strings well. I would buy again.

Great TPU When Using Direct Extruders

This TPU filament is tricky stuff when using a Bowden extruder, but works like a dream with my Flashforge (direct extruders). I tried it on my CR-10, and the results were not so good. Somethings printed OK -- barely so, but it seems the filament retractions with a Bowden extruder causes pulsing of the extruded TPU. This results (so it seems) in the hotend nozzle catching the tiny blobs of plastic on the next layer, and making the layers messy. I will try again with the CR-10, as I believe reducing the retraction to about 2.5mm, and using no infill will help. I do think the infill printing is where print quality really suffers.Because the filament easily produces excellent TPU prints with my Flashforge, I give it a 5 star rating. Those with Bowden extruders need to understand that Bowdens are great for fast printing, but fall down on flexible filaments. The filament, when used in my CR-10 was feeding correctly, but as stated, the long path retractions are very likely the basis for poor results, NOT the filament.

I got some of the red TPU from SainSmart a while back and have really liked it. The slight translucence makes for great looking prints and it prints very well to this day. I was going to write a 5-star review for it but never got around to it.Then I recently picked up some green. Not sure if I got a bad spool or what, but it is absolutely useless. Exact same settings, speeds, temps etc as the red stuff, even the exact same GCODE file, it jams within the first couple of mm of any print that I do, sometimes even on the first layer. I cannot print with it. Completely useless to me, waste of $25. Yes I fully dried it and it's stored and printed from a dry box. It feels quite a bit more difficult to feed into the extruder, almost like the melting point is way higher. I've tried 30 degrees below what I normally use and 30 degrees above and everywhere in between. It simply does not work. Diameter seems close enough to nominal from what I've measured.So I'm sort of torn on the SainSmart TPU. If you get a good spool, it's great. I still use the red stuff, in fact I'm printing with it as I'm typing this review and it's looking beautiful.... after spending most of today and yesterday trying to get the green spool to finish even a single small print.If you do get a good spool, here's some tips:1. I have to print it HOT. This has been the case with every TPU I've ever used, and it's no different with this. I run it at 235C to get a consistent extrusion.2. The adhesion of this stuff is absolutely mental on PEI. Get your Z offset pretty high. Do not squish it too much into the bed, or you will never get the part off. PEI is great, but you want a pretty sizeable Z offset. Or add some interface layer like Elmer's purple glue stick or something. But I've always just done with a high Z offset and haven't had issues.The good spool, red, I have printed nearly the entire spool already, some up to 29 hour prints with zero issues.

Very surprised how well it worked. Expected problems but got excellent prints.

My first experience with flexible filament and I didn't think there was a chance in the world I would ever get it to print correctly.First test, excellent print. No tweaking needed. Used an E3D V6 on a Davinci printer set at 225.Output has a very cool, kind of sparkly, translucent look. This was much easier to print than the glow in the dark ABS I recently purchase from Amazon.This was the first print that actually impressed my wife. I have done several tank treads and iPhone cases.

Love the results.

The material works great. It is a little harder to load than regular filament due to flexibility. The best way to load is to heat up the extrusion head and push it slowly by hand, do not rely on the feed motor to load it because it will try to load too fast and the filament will bend. Once filament starts coming out, then it works perfectly.I used it with 210 temperature for the extruder and no heat for the plate.

Works great - but you'll need to slow your print speed ...

Works great - but you'll need to slow your print speed down considerably.I found best results with Bed at 80C, head at 205C, but most importantly, print speed around 20 mm/s.Faster speeds the filament would clog up because my MK8 extruder couldn't push the soft material any faster.

Great TPU

By far the best TPU. Once you get the settings dialed in, it��s incredibly consistent.I used 3 rolls then they ran out of stock. Had to use 3 other brands that just weren��t nearly as good as this.
