329688 50141 TPU Flexible Filament - 1.75mm - Black

Every roll of Foxsmart yields the same great results time and time again.It's my #1 go to source. I really do have 10 opened rolls in my cupboard that I switch between depending on my color preference.And their product is cheap for what you get!Specific to the Black and Clear TPUI LOVE this stuff. On my Robo3D R1 Plus Hexagonal Hotend (now upgraded to a E3Dv6), this stuff prints wonderful. It has great flexible properties and it's printable without a heated bed. But I get best results with a 40-50c Bed. I can't remember if I've ever had a print lift with this stuff.Once you have a piece of PTFE tubing in the path after the hobbed bolt, you will find that printing is not that hard.I can print this without issue at about 20-25mm/sec which is much faster than the Ninja flex because it is very flexible but just a tad sturdier than the Ninja flex. Possible issues on a wade extruder setup is that the force required by the stepping motor might just be enough to tighten the large gear making the hobbed bold assembly tighten the wheel and making it stop. I've thought about drilling a hole into the bolt so I could put a cotter key in the nut with the nylon so that it does not tighten. If you print this filament too fast it can wind around the hobbed bolt so you need to watch the print process.I was able to print a 32mm washer with a 19mm hole in it to serve as a water tight seal and it worked! This is wonderful stuff.Largest item I printed was 200x200 and 50 mm high. it turned out great.I love the little paper that says there is not manual in this box as you won't read it anyway, which is true!

-UPDATE-I contacted the seller and they have informed me that this is TPU, and the label is wrong. I will be doing a few test prints and dissolving a bit of it in solvent to see if it is indeed TPU. This sort of mistake even if it turns out to be an honest one leads to a good deal of confusion. I am not likely to purchase from this seller again.I haven't printed with this yet, but the product I received is (labeled) orange flexible PLA not TPU as advertised. They are not the same thing.

Prints very well on my The New Matter MOD-t 3D Printer. I print at 30mm/sec at 220C. If I print with infill < 5%, I get a nice spongy part. Adding more infill increases firmness until the part seems almost solid, at around 20%. The color is nice and the parts can withstand being in the freezer, or dropped into boiling water without ill effects.

Does not work for my XYZ 3D printer

This stuff is beyond amazing. it is so insanely strong its ridiculous. I would call some of the prints made from this close to indestructible under normal use and even mild abuse. truly amazing. sucks at overhangs but for anything compatible with it truly stunning results.works particularly well if you increase heat and SLOOOWWWW down the print speed. the slower/hotter you go the more metallic/glossy/transparent it prints.it prints at 80mm/s just fine but its opaque and not "pretty" like the slow prints are.First pic is a bunch of TPU both thin and thick. the two vases one is single layer the other is also single but super thick (.4mm versus near 1mm)3rd is me scrunching up the thin one and it not caring one bit. returns to shape and lastly super thick an entire rocket printed in this stuff. I think I could slam that rocket into a wall at 300mph and it would just laugh at me and say that all you got. its that strong.

I'd love to try the stuff but I can't get it to feed through my Printrbot Simple. Probably more the fault of the printer than the filament.

I didn't pay attention to the "Flexible" part of the description (yeah, fourth word in the title), but I'm sooo glad I misread it, cuz printing with limp noodles is a gas!Once you've figured out the oddities of this wibbly filament, you'll love it. Printing through a (mostly) basic bowden about 18" away from the hotends.Backlash can be brutal, so retraction is disabled and I used some spare bowden tube enforce good behavior (see closeup extruder pix for simple mod).

It prints easily using my BullDog XL extruder and E3D v6 hot-end at 20mm/sec. It is unbelievably tough material and the color is amazing- fluorescent green and very shiny like glass- beautiful! I print at 215C on a clean kapton covered print bed set to 80C and it sticks perfectly. No smell while printing! Highly recommended!
