TPU Filament，PRILINE 98A TPU Flexible Soft 3D Printer Filament，1KG 1.75mm Spool Durable Flexible Material, Grey

So far, outstanding print quality at 215C, 25mm/s when filament is kept very dry. Product claims softness of Shore 98A, which would suggest slightly less flexibility than Shore 95A, which is common with other common TPU varieties. That's exactly why I purchased it and it delivers. Additionally, thin sections can be flexed hundreds of times with no appreciable change in properties, which suggests that the parts will have the famous TPU durability. My only disappointment is that when parts are flexed and then released, they only recover about 50% to their original shape. The other TPU I have experience with is Hatchbox, which recovers nearly 100% to the original shape, making the Hatchbox far more useful for what I had intended. Since the mfgr. makes no claims on resiliency (that I saw), I have no basis to demote the feedback rating, but next purchasers should be aware of the properties they can expect. Update 2021.05.12: Rather than using this for applications requiring flexibility, we find this is our go-to material for applications where the parts are actually going to be used and where we would otherwise have used PLA. If we just want something to sit on a shelf and look good, we can use up the PLA. But if the parts are going to be handled, assembled, dropped, drilled, screwed together, and stepped on, we use this. This material is what should be used when you want to make something really useful. Update June 2024: -Dry thoroughly (can’t be over emphasized) -Use a max volumetric flow of 2mm3/s to automatically limit print speeds (independent of layer height or width) -Use 200c nozzle temp (yes, it seems low, but layer bonding is still perfect and detail/bridging rivals PLA) -use 1 degree ramping lift to further minimize stringing, but with dry filament and relatively low flow rate, there shouldn’t be much stringing anyway. This stuff is extremely underrated for making very strong, useful things.

This is the best 98A TPU I've used. -Prints super clean at 210C. Very minimal stringing when tuned properly. -Proper plastic spool - none of the cardboard garbage so many others are using. Priline - please keep it this way! -Works great with my Bambu H2D and AMS HT. -In black, it has a more matte finish than most TPUs, which I find appealing. -Has some flexibility without being super rubbery, even when printed solid. -Good price. Some printing tips: TEMP: 210C proved to be a sweet spot for me. RETRACTION LENGTH: Avoid significant retraction as it can cause ugly wall gaps - keep it at 0.4mm or less. Z HOP: A normal-style Z hop of 0.4mm works nicely - avoids top layer travel scars without producing stringing. RETRACTION SPEED: 30mm/s worked well for me. TRAVEL SPEED: In lieu of relying on retraction for ooze avoidance, ramp up the travel speed - I use 1000mm/s. PRINT SPEED: 40mm/s gives me clean walls. K FACTOR: I've had success with 0.2.

This stuff is great. It prints very easily and even at a high speed on my AD5M and 5X. Just remember that it's stiffer than 95A. I'm a repeat customer for sure.

Follow-up after many rolls: While I still love the unique combination of increased stiffness (IRT standard 95A TPU), durability and print quality, there is one major issue I continue to have with this filament: diametrical consistency, which I have found to get down at times to close to 1.6mm. This filament prints less-consistently than much softer flexible materials for this reason. My dual-drive extruders print any flexible material without issue, as long as the filament diameter stays within range. But flex materials are very sensiitive to filament diameters getting much below 1.75mm, because while the extruder will continue to drive the filament, the thinner filament will start to push out the side or bunch-up and then back-up on itself. Unfortunately this filament has this issue, and the result is that 20%-30% of identical prints will fail without operator intervention. Again, zero issue with much softer filaments used on the same parts printed on the same machines. It's a bummer, and I hope Priline can fix this, because the material itself is quite useful. But QA matters. Follow-up: I'm using this filament on a regular basis, in places where I would not have thought about using a flex material before. The print quality is almost indistinguishable from similar prints in PETG, and I'm starting to use it in place of materials like PC, PETG and ABS in places where I need mechanical strength with a little bit of give instead of potential cracking or delaination. I wanted a TPU that was a little stiffer than Sainsmart for some structural parts that also had some flexural areas, so picked this up. To test it out, I threw it on my printer and printed this overhang pyramid using a stock 3mm layer height Sainsmart TPU print profile. I was amazed at how well this filament printed. Not just amazing for TPU, but a really great print for any filament. On top of that, the print can be crushed and then pops back to it's original shape. Layer adhesion seems exceptional, and the preservation of detail is really good. I need to work with this filament more, but it seems to be a really interesting combination of tough, slightly flexible and able to produce really detailed and nice looking prints, and it's a fair price for the quality and unique features. Note that I've only printed with the black thus far, and have just begun using this, but I am impressed out of the gate.

I've only done a couple of prints so far, but they have been excellent. I see a few others have mentioned clogging issues, but I have had no trouble so far with a .04 nozzle. I tweaked up a custom profile to make it run in my AMS and it's working flawlessly. For those curious, I used the "Bambu TPU 95A HF" profile, then saved a copy for Priline and edited it to change the material type to PETG so that the AMS wouldn't reject it. The only downside is that the AMS display shows PETG in that slot, but the profile prints very well. The stuff is quite tough and responds well to changes in infill and perimeters, so if you need more give, you can just make a thinner print with less infill. For the record, if you're planning on trying it in an AMS, I have heard that the other colors might behave differently, so try the black first. Edit: as if to make a liar out of me, the very next print I attempted got hung up in the AMS and I had to removed the PTFE tube, cut the filament at the spool and drag it out CAREFULLY. Lesson learned. Still good stuff, but I guess I agree with Bambu: don't put it in your AMS.

I am very pleased with this filament! I made a phone case and it came out very nice. I printed right after opening the package and didn't have any issues with moisture content, but I still put it in the dryer while the printer was working. I print almost everything from a drybox tho. The filament seems slightly stiffer than my Polyflex TPU95, but the print was thin, so I'm not for sure to what extent. I am very paticular about filament quality (mostly use Polymaker) and have thrown out spools or given them away for poor quality. I used the default Bambu TPU95 settings on my X1 Carbon and its very close to perfect. The default support spacing is adequate for this filament too. I'm extremely pleased with the filament's ability to print overhangs and also experienced no stringing. Just make sure to use plenty of build plate glue/adhesive because like many TPU's they stick so well to the build plate, the glue is actually a release agent.

PRILINE 98A TPU: I had to write a review for this as I did finish printing an FPV drone part. This is the best looking print I ever did manage to produce. Smooth, no artifacts, clean, solid, detailed, matte print. Very visually pleasing print. Even though the settings on Bambu Lab Mini are for strength 0.20mm profile (not details profile), details came out as if printed professionally by the manufacturer. I do not recall any filament I used before prints at this level of smoothness. Large spool. initially the spool tangled up and the printer kept thinking there was filament, and printed half invisible object. 0.4mm strengthened steal nozzle 210c temperature 50 mm/s speed all over 30c bed temperature No Retraction

I've been pretty impressed with this filament for the most part. Yes it's not as flexible as other TPU filaments, but it's still flexible and prints well. My only issue has been the filament diameter. Generally the diameter is around 1.65 to 1.75. So not as good as they advertise but it works. However as I was printing a 6 hour print I left it after 2 hours and came back to a ruined print. The hot end wasn't jammed, the spool wasn't stuck, but the filament was less than 1mm thick for a 6 foot period so my extruder couldn't push it through. I've posted some photos where you can visibly see the difference. I really want to like this filament, and I do, but I don't plan on any really large prints with it anymore.

This TPU filament works great with my Bambu Lab AMS Lite! The quality is top-notch—it's flexible, durable, and prints smoothly without any issues. I’ve had no trouble with warping or adhesion, and the flexibility is just right for my projects. It’s great to know that it’s compatible with the AMS Lite system, making my 3D printing process even more efficient. I’m really happy with the results, and I’ll definitely continue using this filament! Highly recommend for anyone using Bambu Lab equipment or looking for reliable TPU filament.

buena calidad de material

Was afraid that tpu would be too soft for my ender 3, but it worked quite well. I assume it's stiffer than most tpu so there were no feed problems.

Good one, harder than tpu 95

I’m giving this filament two stars I’ve only been able to complete one print as it tends to clog the extruder and or jam in the feeder quite easily. I’m giving this filament two stars I’ve only been able to complete one print as it tends to clog the extruder and or jam in the feeder quite easily trying to use it to print parts for an RC car the one part I did complete turned out good. But it seems as though I need to clean the extruder and re-feed the filament between every print. Unlikely to buy this again.
