YOYI 3D Flexible TPU Filament 0.8KG 1.75mm Flexible TPU 3D Printer Filament, Diameter Tolerance +/- 0.03 mm, 0.8 KG Spool, 1.75 mm (Blue)

 Awesome!! Cant say much more. Kept my PLA settings except for priting speed which i cut in half. 2 iphone cases, baby groot and this rocket for my son, all flawless.

I got this material for making cell phone cases. TPU is use for applications where there might be high impact, so it should be a good choice. The filament is a bit tricky to work with if you don't have your machine perfectly dialed in.After re-adjusting the gap between the extruder & the hot end feed tube, the filament blow outs stopped. It worked best at a layer height of 0.3mm. Designs are a bit tricky because the material is so flexible.

So far I enjoy the filament. Using a Wanhao Duplicator i3 Plus with this is pretty easy. It has a direct feed to the nozzle which is preferable for flexible filaments. As far as settings go Im using a nozzle temp of 200 C and a bed temp of 60. Still experimenting with the temps so far.note, in some places online it says to use a nozzle temp of 220 or so. This produces micro bubbles in the filament giving it a more opaque look and a stiffer finished product, hence my 200 C recommendation currently.

Great filament for the money. Consistent diameter, and consistent quality.Print settings:70C glass bed with PVA glue stick.230C nozzle first layer, 205C nozzle all other layers25mm/s for direct drive, 20mm/s for Bowden drive (0.6mm nozzle)Fan off first layer, 100% for all other layers.

I was able to get this filament to work on my Monoprice Maker Select V2 using speeds from 20-30mm/s. I was able to make an oring for a container and it makes a great deal now.My biggest comment is that when printed, the part is far less flexible than I thought it would be. It’s by no means rigid, like a PLA or ABS part, but it’s not stretchy. I have tried different infills and found it’s more stretchy with lower infills, but if it’s too low (5-15%), the part doesn’t print very well.Bottomline: if you intend to use on something you want real stretch with, this may not be the filament you should use. If you want to try TPU for things like phone cases, this would work well!

Printing this on a D-Bot CoreXY bowden style printer, E3D hot end .4mm and Bondtech QR extruder. Working very well at 15mm/s, no problems so far at all. Printing on a PEI sheet at 70C at 220C, I find it tends to stick really strongly, so a bit of care is needed to remove to avoid damage to the print.I have been doing 4 solid layers top/bottom to give it some strength to reduce damage when removing from the PEI. If I print any faster, I find I don't get the layers and cleanly as I'd like. You will get some stringiness, but easily removed.

Prints great and weighs more than advertised. Printing on an 80C bed and extruder at 235C. Prints beautifully.

So far I am very happy with this filament. It's been working great at 220F on my FlashForge and so far it's by far the easiest type of filament to get perfect prints that I've used. Its also very tough, has very good flexibility, and layer adhesion is great.
