I wanted to try TPU for some time now, But the fear of getting filament tangle in extruder gears kept me away from it. But this filament is really great. Its tough enough to be retracted and flexible enuf to make some really cool things. I designed this Iphone X case and set it up for print. After first layer, I realized that I had a lot of overhangs and bridging (which I would have normally ignored in a PLA/PETG print). I was afraid none of that will come out well. but lo and behold the filament handled bridging like a champ. I was very impressed by the results.Printer and Print SettingsPrinter: Prusa Mk3SSlicer: S3DBed: 50 deg C with Glue stickHotend: 212 deg CNozzle: 0.4mmLayer height: 0.15 mmLayer Width: AutomaticRetraction: 0.8 mmZ hop: 0.6 mmAmbient humidity: 95% (it was raining)Enclosure humidity: 35%Printing Speeds: 15mmps and rest of the speeds 90% of base speed.Why 4 stars?Good things,Love that you could retract.easy to handle and print.never clogged once in 18 hours of printing.Things that could be interpreted as good or bad based on perspective,Cost: Good filaments always cost more. and every-time I consume one, I know why and feel the difference. But it can be a negative for you if you are an expert in TPU and just want to get on with printing at lowest cost.Filament size: I think smaller spools are the best for casual or low volume print. but a headache if you want to print volume.Things to improve,Stringing: My Expectations rise, when I get a costly filament.Spool information: Geeetech is notorious in not providing any recommended temperatures or anything else on the spool. but the plus side is that their support is pretty responsive and gives you updated info.I might try again after drying the filament. Maybe it picked up moisture during the time it was out of packing and now.Hope you all find this review useful. Happy printing.

TPU and TPE are usually a pretty mixed bag when it comes to quality. But the Geeetech black TPU is very good. It has a stable printing temp between 220 and 230 depending on your print speeds. As long as it is paired with either an ERZ extruder or BMG Bondtech or clone you can use up to 5mm of retraction without any issues. TPU like other materials is hydrophobic, meaning it retains atmospheric moisture and will need to be dried. Please keep it in a zip lock bag or plan your prints out in advance.All of my test prints came out beautifully Especially the vase and rocket. Surprisingly the Benchy did ok too other than some stringing on the inside of the cabin. The bow is very smooth without any wobble and all of the lettering is clear. Important to note that the first layer was gorgeous.*Disclaimer: I am using an Ender 3 with many upgradesPlease make sure that your bed is level and live adjust the layer height as needed (or baby step Z) if the layers are to transparent or spread apart. Calibrate PID for 220 before printing this TPU so that the temps are stable for the length of the print.Print settings I used are as follows:Print temp 225Bed temp 68 on Blue Painters tape5mm retraction for prints with multiple parts otherwise 040mm retraction speedJerk OffJerk Acceleration OffCoasting OffCombing not in skinWhen using supports make them as light as possible because no matter what you do supports will bond to the main part.I hope you enjoy this filament as much as I have. I will definitely be getting more from Geeetech.

I like this TPU filament. Being flexible there are certain applications that it is ideal for. The day that the “translucent red” TPU from Geetech arrived happened to be the day our fly swatter broke. What a perfect application for TPU. I found a fly swatter head design on Thingiverse and printed it. Having worked with TPU before, I chose a slow print speed (20mm/sec) and relatively hot temperature (230C) to extrude. The results were perfect the first time. I had good flow, strong interlayer bonding and good bed adhesion at 60C. The flies on our patio are in big trouble.I like the looks of this filament. It is translucent, kind of sparkly and very strong. I also like the idea that it is packaged in a .4KG spool since most of my printing is with PLA. Geetech has a very nice selections of colors. It's the best TPU filament that I've worked with.

This was purchased from amazon. The roll came vaccum sealed and had such a vaccum it flexed the spool itself so I would figure the filament would have been dry. Now I have only experience TPU once before, and that roll had the same problem as what this had, which is moisture. Thankfully TPU is really easy to dry if you have a food dehydrator, it is quite hard to deform the plastic since this is flexbable.When I first started trying to print with this it would snap crackle and pop and had a really hard time printing a temp tower. After drying this did get further into a temp tower however the cooler temps on the temp tower failed, higher temps printed quite well. I also printed the flexible octopus and the before and after drying is also much different. I am noticing top layers not coming out as well so I may need to play with fans and temps to get those coming out better.You will want to make sure your printer is prepared for printing flexibles. Your feeder must have a restricted filament path so the filament does not flex out of the feeder unit. Take a look at the bmg or creality style feeder units since their paths are restricted enough to feed this filament.
