SainSmart 95A TPU Filament 3D Printer Filament Colour Changing with Temperature 1.75 mm 1 kg/Spool

Love this color changing tpu and I want more colors

Very easy to use great color

I use a lot of TPU - it's my favorite filament. Lens caps, covers and cases. Window parts and more. For a text print I decided on a holder for small cans of Red Bull. Yellow means it's warm, orange is cool. I had to keep an eye on the printer spool - the stuff is very flexible and jumped over the spool sides twice where it proceeded to wrap around everything. After the second time I attached a bracket I made for situations like this but have rarely needed. Basically a big "L" that rests on the top of the spool and attaches to the spool holder, to prevent filament from going over the edge. This stopped my tangle issues. Will this happen to you? Who knows - but keep an eye out.Apart from that, printing was flawless and printed at TPU defaults.Orange on the spool, but after printing it stays yellow at room temperature and turns orange when cooled.

The media could not be loaded. I enjoy trying out new and interesting filaments. This color-changing TPU filament caught my eye and I just had to try it, so I ordered a spool.My first impression of any filament is the spool it arrives on. The spool is made of plastic and has two sets of holes for holding the filament so that it doesn't unwind when not in use. The filament appears to be wound more chaotically than what I'm typically used to seeing for PLA-style filaments. That being said, I did not have any issues with tangles while printing.I loaded this filament onto my Creality Ender 3 S1 Pro with a direct drive extruder. I sliced up a model of a Mario Kart tire using settings fined tuned for TPU. The model printed well without warping, clogging, or tangles. The filament adhered well to itself and the PEI bed. The model looked fantastic after it was printed and retained its bright orange hue.The main gimmick of this filament is its color-changing ability. I was impressed that this filament was able to change from bright orange to bright yellow using body heat alone. After touching the filament, it changed color. The yellow color stayed for about 30 seconds before cooling back off to bright orange.Like other TPU filaments, the resulting printed object was spongy and squishy. It feels a bit rubbery.I think this color-changing filament is a lot of fun. I'm going to print off some fun toys with this.

Every other TPU brand I've tried has printed effortlessly, but this one required constant effort. It needed almost as much drying as a nylon. I've never had to dry ANY other TPU. I could only ever get layers to adhere at 1.2mm. At 2mm adhesion was super poor, regardless of temperature or printing speed. Bed adhesion was difficult as well. The color change is pretty cool, but that's not enough to make up for the poor print quality.

I did not expect this to change colors. I got it for the orange and tpu.I printed and thought it was odd it was a different color but hey it was dark printing and it was not glowing so was not worried.I went to work and when I cane back it was done. Removed it from the plate and cleaned it up. That was the easy part. Tpu just pulls off to clean up.I went to talk to my wife and was holding it in my hand. A few min went by then I looked at it and saw the yellow. I thought something got on it from my hands like paint or something. Nothing on my hands so I started to rub it with my finger and that dragon started to change colors. Bonus I got something to change colors but with heat.This tpu glues to the plate really well and did not want to come off easily. It like to shine from the light but what tpu doesn't. Is it not rubber?Print quality seems not to be all there and may be related to the temperature of printing so will need to do testing on that part but anyways.I like this tpu and I think you will too.Good Luck in all your printing you do.

The media could not be loaded. This is the first time I have printed with color changing TPU filament and I have to say I am impressed with it. The first layer down was perfect. No adhesion issues with a smooth PEI bed heated to 60, and nozzle at 215. I was really impressed with how smooth it put down with very smooth surface. Then once the print was completed I was very pleased and was better than I expected. The color changing from orange when at room temperature to yellow when you touch it with your hands is amazing. The filament also holds up extremely well to bending as TPU is a flexible material. Really need to watch the video of how sensitive the color changing really is. The spool winding could of been I touch better, but I did not encounter any issues while printing and I think this very well be my new favorite brand of filament to buy. Highly recommend this for anyone looking for that temperature sensitive filament for their prints.

To help prevent stringing I have slowed my print speeds way down in pretty much every case with all filaments, and this TPU is no different. I also found that starting at a lower nozzle temp and working my way up to the desired temp is helpful as well. I found that about 210 with a 50 degree bed worked well at 20 mm/sec print speed.The TPU works well. It is not as stretchy as advertised but the flexibility is really good. I also use a Bowden tube style extruder. It's not recommended, but I have used it with both TPU filaments I have and it has not caused any issues. I probably would not try a really detailed print, but for making RC vehicle tires and cell phone cases it works well. The color changing filament is more of a novelty for me, but it's fun to play with.Once you dial in your printer it works pretty well. Just have a bit of patience. And use the profiles feature in your slicing software. I do it by printer and filament type/brand.
