Don't fear SOFT TPU - it's fine to 3d print now.

Thank you @3dPrintsAndLeaves for the manim charts.

In this episode we take a deep dive into 83A, 85A and 40D TPUs to see how hard they are to print with modern, better designed printers.

Curious about the price point on the Phaetos Conch Plus... I looked at the link but didn't see any price (maybe I just missed it)
Just recently upgraded to a diamond-tipped nozzle, so Phaetus' option is going to have to come in less than that, particularly considering even silicon-carbide can't surpass its wear nor thermal conductivity.

Nothing like smooth jazz on Sunday morning

I appreciate the joke with the smooth jazz

3:58 The best laugh I got in this week. Thanks man! That was so great! 🤣❤

I work for UK filament manufacture, we just did a small run of TPU it wasn't easy. your correct remove as much friction in feeding even to pull a meter off the spool just let the extruder pull it in.
if you can fit a stainless steel tube right up the extruder gears to stop filament getting stuck in the gears on the hot end side of the extruder. 3mm OD 2mm ID or cut up nozzle with long heat break tubes.
Set the filament tensioner as high as you can TPU filament is tough and slippy, so don't worry about crushing the filament.
A larger nozzle helps too.
you make great content hopefully sponsor a video.

Oh no, you said "irregardless" :)

Wow, loved the Jazz!! Great testing...glad to know TPU is now pretty straight forward.

If you are looking for matte TPU in 85-95A you can buy the "Add:North TPU pro matte". They come in several colours and are soft and matte when printed 😊

[hellothere]

Great advice, even modern direct drive will struggle with long PTFE tube friction, but bumping up the flow rate, even mid print is an instant fix.

If you have old soggy TPU and no dryer cranking up the flow rate mid print also works great, the surface quality won’t be smooth and glossy though.

Fun fact an ender 3 can print ninja flex 85A TPU at 20mm/s quite nicely

[fredhamilton]

That last point (“it is and always has been about flow rate”) can’t be emphasized enough. I gradually came to that conclusion over the last year but it really needs to get into everyone’s brains who are used to fretting over 20 different speed settings in each slicer (and filament profile) they use. Deserves its own video!

Funny enough, I've gotten 70a tpu to work on my slightly modded ender 3v2. Still a bowden, but with a dual gear extruder. It isn't perfect (might need a bit more tuning on my end), but it works surprisingly well. I use a bit of hand soap as lubricant (a little on the tip, insert the filament, and run it though until the soap stops popping out of the nozzle). A little cursed, but it works.

I've been printing for two years and still haven't touched anything other than PLA, but TPU really does open up a ton of new applications. This video definitely removed some of the apprehension about getting to grips with an unfamiliar filament type, might have a buy a roll or two and see how it goes :)

I just 3d printed my first flexible print out of beyond plastic PHA flex. It is supposedly fully compostable in a home composter or it can be thrown away. Sadly. The company isn’t making any more rigid or flexible PHA, but I know that some other companies are selling/working on making it commercially for consumers.

I love your videos. Legit laughed my ass off when the music started playing! 🤣

[joherberth]

I tried various brands of 95A TPU. I had no issues with all of them. Even Soft 83A TPE works fine. After a half year not printing any flexibles i want to print something and nothing works. My prints looks terrible and way underextruded. After some research i remembered that i changed the nozzle to a hardend steel one. I changed it back to brass and works fine again.

[SianaGearz]

Well can't say i have heard jazz this smooth before...

[GreenFox]

I was 🤏 this close to call you out on "irregardless" before seeing your keychain.

[ausfoodgarden]

My kind of jazz.😉 Thanks for the info, I've not printed with TPU as yet, so this will help me a lot when I do.
Cheers!

[justinkirschenman]

I had no idea I would like jazz.
Thank you for expanding my music tastes.

I've honestly never had issues with the extruding part. It's just the bed adhesion that never works with tpe/u for me. I've textured and smooth pei, painter's tape, gluestick, magigoo, dried the spool, designed a custom brim with tabs that are easy to snip off. It worked a few times but now it no longer works and I have nonidea why. It really doesn't make me want to try a new spool, this stuff is expensive.
