Polymaker PolyFlex TPU95-HF 1.75mm Flexible TPU Filament 1kg Spool - High Flow, Shore 95A, Clear 3D Printer Filament for Cosplay, Phone Cases, Wearables & Flexible Parts

Printed nicely and evenly. Great for multiple projects and I love the color!!I have used a lot of Polymaker filament of all types so I tried their TPU, it's Ok but is not as glossy smooth as the other brand I had been using for a few years. Not sure if I'll continue using this TPU. Unless I can tune it in better.The high flow tpu works as described. Can print with much higher speed with no clogging.Good quality TPU, printed really well after a bit of adjustment. I've been printing 100% infill (well, very thick top/bottom thickness anyway) and when you cut a print in half you can't see layer lines, the material is 100% bonded and extremely durable.Biggest difficulty is under extrusion. Your extruder gears will not push the same amount of filament as a solid plastic, so you must calibrate your Esteps, or if you want to do it through a printing profile specifically for TPU, up your flow rate. On my MK3S I went from 100% flow rate to 120% to stop under extrusion.Retraction is difficult to tune, keep it low. I went from .8mm 35mm/s to .1mm 15mm/s on a direct drive setup. Probably the hardest part of getting good looking prints.Other than that, fairly simple. Print hot, print slow. After messing around with printing this stuff for 2 weeks the only thing I can't comment on is the longevity of the prints.Oh, and A+ on the cardboard spool. This hobby is wasteful enough without the plastic spools.I was skeptical that my Ender 3 would be able to print with this filament but it pulled it off no problem with some slicer tweaks. I used PrusaSlicer to generate the g-code for my tires and my tweaks where: 225C print temp, 30mm/s print speed, 3 shells (thicker wall=stiffer part), retraction length: 3mm, Extra Length on Restart: 1mm, ( I turned off Ensure Vertical Shell Thickness, that speed up the prints and reduced the number of retractions improving my results a bunch) And the filament stuck wonderfully to the default textured PEI my printer came with.--CRITICAL YOU MUST CHANGE THE RETRACTION SETTINGS (see image for my settings)--Flexible filaments are prone to stringing it's just how they are, try to print only one object at a timeand clean up stingers with sharp scissorsA note on Bridging with flex filaments: IT SUCKSso if you have to do it use a ton of top shells (8+), decrease the layer height of the top with the slicer's variable layer height feature, this will give you the most chances to fully bridge, and change the bridging flow rate to 0.75.Just remember: Print Hot, Print Slow.This stuff prints great, if it is DRY. Some TPU you can get away with printing without a dry box, leaving it out in the environment… not this stuff. That’s not an issue but I just want to emphasize to anyone buying this that you need a drying solution to get good results with this particular TPU. Dry it out and you’ll be happy!First time use of TPU and I found this to be very easy to print. Using a Prusa MK3 I choose the FIllamentum Flexfill 92A profile and adjusted the temperature to 220 and saved it. I used the default 0.2 layer height settings and adjusted any speeds greater than 50 mm/s down to 50 mm/s (recommended max speed per the guide). Everything printed better than expected on the first print. I did have some stringing when I printed multiple small parts closer to each other that was easily cleaned off. I have not yet taken the time to tweak anything to minimize stringing. Over I am very pleased with the PolyFlex90. For that matter I have been happy with every filament I have used from Polymaker.Se perdió la última estrella porque en la descripción marca 1 kg, cuando en realidad es 750 gr netos de filamentoPero, tiene una belleza bárbara al imprimirlo, otro nivel.I've used PolyMaker for little over a year now and have been really impressed with the consistent quality and pricing. I;ve never had adhesion problems or print quality issues, I've used several other brands and still go back to Polymaker not only because of cost but biggest reason is print quality. I use a Hemera with plated copper E3D heat block, titanium heatbreak and CHT bondtech nozzle and have to say this can keep up with my high expectations. I live in Canada and can get Prusament filament or Proto Pasta but the cost is insane and honestly cant tell any difference in quality between these brands, so diffently worth every penny buying PolyMaker. They have a huge selection and I own just about every color in PLA, PETG and PLA Pro and lately been using some PLA-CF to make printers parts and wow is it good and strong.i thought i would have such a hard time getting the right settings and upgrades done to my printer in order to print high quality prints with TPU.only issues i had were with bed adhesion, other than that i got good prints from the first use, the color looks amazing, filament is very durable and stretchy.printed on ender 3 and only mod done was upgraded metal extruder.After watching some tips on how to print flexibles, I loaded it up in my Monoprice Maker Select Plus printer and after some bed leveling and tweaks with my extrusion multiplier it easily printed.J'ai imprimé se produit sur une prusa mk3s. L'adhésion entre les couches est très bonne. Des ajustements son requis sur la vitesse d'impression. J'ai imprimé à 230 degré afin de faciliter l'alimentation à lextrusion. Mais beaucoup de overhang. D'autres test à faire. Mais très bon produit!With retracton set at maximium we still had stringing problems with small objects.
