eSUNFlexible TPE Filament 1.75mm, TPE-83A 3D Printer Filament, 1KG Spool 3D Printing Filament for 3D Printers, Black

I tried printing some custom drain gaskets in TPU, but wanted a more compliant material.Wow - this stuff is amazing!I think it will be ideal for custom gaskets and seals on fittings.Only tried it for this project so far, but it is very flexible and prints very well.Little stringing noticed, partly because of the shape, but it looks and feels great.A 20mm 3 wall test cube prints at a flow rate of about 95% to get 1.8mm walls with .6mm nozzle.Currently printing at 240C, first layer at 15mm/sec and the rest at 20mm/sec.You will have to experiment of course, but it is worth it if you want a nice flexible part.On my list of great filaments.

I wanted an alternative to the 85a Ninja flex, and this does ok. I think ninjaflex is still a bit more flexible, despite the higher reported hardness. It prints easier than the ninjaflex and has less stringing. It also has a more matte finish than the ninjaflex. I'm just not sure I'm convinced of the stated hardness values.

eSun TPE-83AThis stuff is amazing. It'll have you standing at the printer poking at the object like it was your first ever print because it is so interesting.So far, I have used it to make a cheek rest and a shoulder pad, and it printed extremely well. I printed on a Mk3S from a Sunlu S2 dryer via (very long) reverse-Bowden at moderate-to-low speed, and the only caveat was that I had to run 110%-115% flow (adjusted live on first couple of layers), I am guessing to compensate for the friction from the Bowden tube. I saw some upward curling on some thin (2-4 mm) unsupported ~40° degree overhangs, but the curling eventually self-corrected when the objects filled out and converged, resulting in a relatively minor cosmetic defect. Otherwise, this stuff printed extremely smooth and flat, and even tree supports came out pretty good.Not only can you use it to make objects anywhere from somewhat compliant to amazingly flexible, I believe you could use this to actually print fully functional gaskets and other seals (I have always harbored doubts about doing this with TPU). I think you could even use it to print custom-sized rubber bands, based on the properties of the purge lines and skirts that came off the prints.It is a little pricey, but nothing too crazy (not crazy like PA6). You should buy some so eSun keeps making it >

They are winding these on cardboard spools and wont update the listing to reflect the actual product they offer.This formula also seems to be different from the previous rolls I purchased... Before, it actually felt like rubber and had a rubbery matte finish, but now it is more of a plastic shiny finish as if it is 95A or somewhere in between the 2. This is really unfortunate because the previous rolls I purchased were amazing, and I was able to make really good antivibration feet for my printer. Now this stuff is too stiff where it is just as bad as the 95A TPU I have. I honestly feel really ripped off, and I dont think I will be buying this again in the future.Also, eSun is pulling some shady business by flagging negative reviews that state the filament arrived on a cardboard spool instead of a plastic one. How is amazon warehouse responsible for how eSun is manufacturing the product? This is a loophole that way too many companies are abusing, and Amazon needs to fix it.On top of all that, eSun has bad customer service. I contacted them about the TPE 83A being on cardboard spool when it is advertised on plastic roll, and they asked me if I want an stl file for a plastic ring so it fits in the AMS system... Umm, you cant put TPU/TPE in the AMS system, so why the heck would they even offer such a stupid solution?

I should have weighed the spool when I first got it, but I swear it’s WAY more than 1 kilo. I’m not complaining but it’s by far the most I’ve ever gotten in a single spool. It’s very flexible. It does exactly what I needed it to do… be grippy pliable but strong. You cannot rip it apart even when I print in vase mode. It’s a bit expensive, but I when compared to other filaments that have a shore hardness lower than the lousy and inflexible level everyone seems to have settled on, you’d have to pay over $100 for this quantity. I feel like I’ve got a lifetime supply. Just buy it!
