@@TheGameIsFunny The harder TPU (95A+) Are quite easy to print, but I would highly advise having filament dryer for quality reasons - when I printed with TPU out of the box, It already had too much moisture, terribly affecting print quality.

[@notyouraveragegoldenpotato]

Never used it before a week ago, had an idea to make something and decided to give it a try. It was cake. Honestly. And was able to print WELL at much higher speeds than they say. Basically printed it my normal speeds. Super cool stufd

[@RegularOldDan]

I've loved flexibles ever since I tried 95A on my old bowden-based printer nearly 6 years ago. The poorly-constrained filament path meant I had to babysit the first few layers (I would sometimes release the pressure by opening the extruder a tad) but once it got to the third layer or so, I generally had good luck. I've gone down to 82A without issue on my Prusa... now I wonder, do I dare try 70A?

[@LostInTech3D]

Absolutely fine on a DD. The key is to go a bit hotter than usual (I was doing 230 I think) and overextrude by about 30% (depending how grippy the filament/extruder is. The thing where I cut the block in half was actually a good diagnostic to see whether 100% infill was actually 100%. 60D is a bit more challenge I believe, but I haven't acquired any yet.

[@Four-sc6gj]

I finally got my printer back running, had to undo my upgraded board after a failure… back to stock E3 pro. I’m about to give this TPU a shot for the first time, gotta rewatch you older TPU vids now.

I’ve found the stock E3V2 setup to be pretty good with TPU. It one of those those thing that can be easily overthought

[@LordHonkInc]

I tried flexibles (just a generic TPU) for the first time on my Ender3 after watching your last two videos, and I was surprised how little problems I had with it. Granted, I've only done relatively small prints (

[@LostInTech3D]

I'm sure a lot of horror stories come from the zero retraction theory which is why I'm so vocal about it :)

[@PRowl27]

One interesting thing that I noticed was that I had to slow down my print speeds for TPU after I switched from a brass .4 nozzle to a .6 steel nozzle. This is contrary to what I would have expected. Do you have any insight into this? My best guess is that there is either more friction in the stainless steel nozzle or poor heat transfer (which would be strange as I am printing at 220).

[@cleanroomwizard2356]

It is likely heat transfer - stainless steel has terrible thermal conductivity compared to brass and a drop in temperature at the tip could be quite substantial assuming the rest of the nozzle dimensions are the same. I don't think the rest of the nozzle should cause much resistance in comparison. I usually go with higher temperatures around 230 for very soft TPU

[@LostInTech3D]

It's got to be the thermal transfer. I really have only briefly tried steel nozzles myself, and threw them out in rage as I had such bad results. I hear you have to print *significantly* hotter to mitigate the poor thermal conduction. Personally I decided I'd rather just use brass and replace it more often, than struggle with steel, but it may just be my nozzles were also poor.

[@PRowl27]

I'll do another temp tower then and see what it shows.

[@paulstrealer5414]

It's definitely heat transfer. I've tried steel nozzles (0.8mm, on an all metal hotend'd Ender 3 with stock heater cartridge), and much like Lost In Tech, I've tossed 'em because of poor performance. You have to run /much/ hotter, and that makes a lot of filaments tricky since they're both getting "too hot" when sitting or making short movements and "too cold" during a long line. Steel nozzles are almost entirely a waste imo That said, something to watch out for with large nozzles in general is that your flow rate is much higher, even with a good nozzle you're going to probably want to print slower. I use a plated copper 0.8mm nozzle for nearly everything I print, and the guideline I use is to be around 3/4 the speed you'd use for a 0.4mm brass nozzle. Give the plated nozzles a try btw, they hold up slightly better than brass and conduct heat slightly better.

[@eideticex]

After thoroughly cleaning a steel nozzle, drop it into a small jar of mineral oil and let them sit in there overnight as well as for regular storage. Makes a huge difference. Just be sure to wipe excess oil off before installing into the printer. Steel can sponge up oil so it'll last for awhile between soaks. During my heavier firing off multiple prototype prints a day, about 3 months.

My recommendation is to use the same speed for infill, inner and other layer. This gives the same pressure all the time. I use no retraction, but high travel speeds. I use bowdentuben setup, and straight gear, and a custom extruder design. I could share it if you want to test it.

[@JB-yu1vv]

Bowden is really underrated, guess because it's popular on cheap printers people might think that it is only for simple stuff. Printed some 82A on a basic Steve and it went really well. I've also noticed the different texture of TPUs, 3dJake's (95A) and extrudr's (98A) are shiny like normal filament, the one from recreus (82A) is more rough. Maybe it's because of the flexibility which makes it easier to produce it that way, dunno

[@LostInTech3D]

Yeah it's a bit of a mystery isn't it. I guess maybe if I ever get to speak to the manufacturer(s) I would ask them why they make it rougher than cheap 95A stuff.

[@cleanroomwizard2356]

@@LostInTech3D I think the roughness is designed to reduce the friction in the tube. If you ever get a smooth filament of the softer materials, the sticking in the tube can be crazy.

I have an Ender3 Pro with a direct drive upgrade and I found that I can print OVERTURE 95A TPU flexible at 40mm/s if I set the nozzle temp to the top temp of 260°C vs setting it at 220°C with top speed of 20mm/s before jamming up. I believe that the faster you go, the higher your nozzle temp should be to keep that back pressure from building up due to the nozzle not being able to keep up with the speed of melting the filament.

I'm sure you've learned this by now, but the durometer you purchased tends to be highly inaccurate and will vary widely from higher end durometer gauges, such as ones manufactured by Rex Gauge. We had a customer claiming our parts we provided to him were out of spec. Turns out he was using a similar durometer gauge purchased for around $20 on amazon with no calibration certificate and no verification on his end that the durometer gauge worked correctly in the first place.

[@Sharpless2]

One day i randomly decided to convert my E3 to direct drive for no reason at all, that was a few years ago. Last year in May i ordered my first roll of TPU. And still to this day, while writing this even, 95A TPU is so much easier and cleaner to print than PLA for some reason. However, even with PLA and PETG, i always really hated the bowden setup with a passion. Its ugly, the couplers are always trash and it limits your TPU choices for those rare cases.

[@ebptube]

I printed out some vibration dampers for my heat pump using 95D. They came out fine and spongy at room temperature but when outside in the coldness they became hard and conducted vibrations in an undesirable manner.

PTFE is just so damn slippery though, you really need something sharp that can bite in. But maybe an internal barb and external TPU fitting? But at that point just get the ones alexkenis recommended.

[@dtibor5903]

You can print any flexible but you need to keep the pressure constant during print, which you can do by: - absolutely constant low speed 20-30mm/s (cura cheats a lot in this regard) - high acceleration what the machine can do (Ender 3v2), no S-curve acceleration. Jerk/cornering speed 10-15mm/s - a lot of retraction (10-15mm) - you need to lube the bowden tube, i use PTFE spray - dual gear is nice to have, lowest pretension (no yellow springs, they push way too hard) - volcano hotend helps a lot with speed, I can print 40mm/s with the hard tpu - you should experiment with 100% filled cubes to find the optimal flow

[@muatok9904]

Seen another youtuber experiment with printing extra soft tpu using pellet extruders with decent results as the feed screw just forces it though without any of the issues soft filament would have

[@LostInTech3D]

Do you remember who it was?

[@alimmomin15]

Im using a Hatchbox's TPU filament on an Ender 3 Pro. Ive only upgraded the stock drive feed extruder to the red aluminum single gear drive feed extruder. My settings are 30m/s, 230 degree nozzle, 50 degree bed, no Z retraction. On the machine, flow of 125, fan off, and run at 80% speed. For some reason I get great detailed prints. You can tune is as necessary but basically I'm going for high temps and slow speeds. When tuned right you don't cause a backup in the Bowden tube since the slight pressure build up from the elastic keeps a steady flow through the hot nozzle

[@janoshorvath9430]

First trials with normal 95A transparent TPU and my biggest lesson was to decrease temp to the minimum. That decreased the amount of bubbles a much and made it look much better!

[@jamiemacdonald436]

I've been printing with Overture black TPU on my Ender 3 V2 neo with very good results, even at 40mm/s. I haven't really tweaked the generic profile all that much other than bumping the print speed up, and increasing the bed temp and extruder temp to the max listed on the filament label. Guess I'm just getting lucky or the material is very forgiving for some reason.

[@petrokemikal]

100% agree.. I got pissed off of the stringing with no retractions printing tpu, until one day I said screw it I'm turning on retractions to see what happens.. Absolutely nothing abnormal happened, I just lowered the retraction speed a bit and all my prints since have been not only stringing free, they also are 50% better prints in terms of layer adhesion, overhangs and just finish... The key is just to accept that you have to print slower.. I don't go above 30mm/s and have had flawless tpu prints..

A Capricorn tube is probably the very 1st upgrade anyone with a 3d printer should make. They do help, can handle temps better (without cooking and producing noxious fumes) and they're a super cheap upgrade. There's no good reason not to fit one.. Tpu95a is actually quite solid and won't be really that flexible unless you use lower infill settings. The hardness of the tpu95a really lends itself to beginners wanting to print something different from pla, without too many changes to settings - z offset being important - don't squish tpu like pla (it doesn't like it). After that, it's just setting retractions using a retraction tower print and slowing the machine slightly to help with the flow. Simples.. I started with bowden and yes, 95a prints perfectly well, though it is "advised" to switch to Direct drive if this is what you will commonly be printing, especially so for the softer, more flexible materials. Good video, thanks, and keep posting..
