Market availability1–5Stocked by most mainstream brands[22][8][23]Ubiquitous, every brand and retailer[9][18][10][17][11][12]
Spool sizes & diameters1.75 mm; 1 kg spools[6][8]1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[9][18]
Typical applicationsLarge or repetitive prints on printers that can sustain high flow[24][22]Gaskets, phone cases, tyres, vibration mounts and protective covers[25]
Diameter tolerance± mm±0.03 (Bambu Lab PLA Basic, rated to 258 mm/s)[26]±0.06 (Prusament) — the loosest tolerance Prusa publishes, because soft filament deforms in the gauge[4]
Printing Parameters
Nozzle temperature°C210–230 for high-speed work; 190–210 at classic speeds[1][22]210–240; Polymaker 210–230, Prusament 230 ± 10, Bambu Lab HF 220–240[3][4][5]
Bed temperature°C30–60 (Polymaker); 35–45 (Bambu Lab)[1][27]25–65; Prusament 65 ± 10, Bambu Lab 30–35, Polymaker 25–60[4][5][3]
Enclosure / chamber requirement1–5Open frame is fine[1]Open frame is fine[3]
Part cooling fanFan on[1]Fan on[3][5]
Bed surface & adhesion aidNot documentedPEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[28][25]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s≈24 at 300 mm/s with a 0.4 mm nozzle and 0.2 mm layer; 30 % more flow than regular PLA at the same temperature[1][22][24][29]2.4 at Polymaker's 30–50 mm/s and 2.4 at Prusa's 30 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer; Bambu Lab's high-flow grade lifts the cap to 200 mm/s (16 mm³/s)[3][4][5]
Warping tendency1–5None[1]None[3]
Bed-adhesion difficulty1–5Sticks to anything[30]Sticks to most surfaces[3]
Stringing / oozing tendency1–5Not documentedModerate — retraction tuning needed; Polymaker specifies 3–6 mm retraction, well above the 1–3 mm used for rigid filaments[3]
Overall printing difficulty1–5Easy — minor profile tuning; needs a printer that can actually reach the flow rate[22][1]Intermediate — dry filament and a tuned profile; the speed ceiling is the main constraint[3][4]
Extruder requirementNot documentedDirect drive strongly preferred. BASF rates its 95A grade as running on both direct-drive and Bowden machines, but every maker caps speed at 15–50 mm/s unless the grade is specifically high-flow[31][3][4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[32]Brass fine indefinitely[33]
Abrasiveness1–5Non-abrasive[34][32]Non-abrasive[33]
Nozzle clog risk1–5Very low[32]Moderate — needs dry filament and a clean nozzle[35]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[36]High — all-metal hotend and strong cooling needed; soft filament buckles in the cold zone if it slows[25]
Hotend requirementNo special hot-end required[30]No special hot-end required, but a direct-drive extruder is (Simplify3D)[28]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % equilibrium at 23 °C / 70 % RH[1]Low (0.1–0.3 %) by Prusa's measurement at 0.04 % in 7 days, but Polymaker measures 0.82 % equilibrium and groups TPU with the highly hygroscopic materials[4][3][35]
Equilibrium moisture content at ~50 % RH%0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[1]0.82 equilibrium (Polymaker); 0.02 after 24 h and 0.04 after 7 days at 22 % RH (Prusa)[3][4]
Drying temperature & time55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[1][27]70 °C for 8 h (Polymaker); 70 °C for 8 h or an 80–90 °C heatbed for 12 h (Bambu Lab)[3][5]
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[35]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[35]
Effect of moisture on strengthPolymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[35]Polymaker groups TPU with nylon, PVA and PETG as highly hygroscopic and says these often need to stay in a dryer while printing; no dry-versus-conditioned figures are published[35]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[27][30]Sealed with desiccant; often kept in a dryer during the print[35]
Mechanical Properties
Tensile strength (XY)MPa43.9 at 300 mm/s and 46.0 at 46.7 mm/s (printed XY, ISO 527); 58.6 on My Tech Fun bars for Creality Hyper PLA[1][37]41.4 ± 1.3 printed (Prusament, ISO 37); NinjaTek Cheetah 39 ultimate (ASTM D638)[4][38]

Other impact dataPrinting at 300 mm/s instead of 46.7 mm/s costs 4.6 % tensile strength and 18 % notched Charpy[1]Not documented
Layer adhesion / Z tensileMPa32.4 at 300 mm/s, 37.3 at classic speed (printed Z, ISO 527); 35.3 for Creality Hyper PLA vs 23.0 for average PLA on identical bars[1][37]9.5 ± 0.2 (Prusament interlayer adhesion, ISO 527)[4]
Brittleness1–5Moderate[1]Very ductile — bends far before failing[3][4]
Hardness (scale-specific)Shore A / Shore D / Rockwell78.7 Shore D measured on printed bars for Sunlu PLA Meta (My Tech Fun), against 75.3 for the same maker's plain PLA[39]92 ± 0.4 Shore A and 39 ± 0.7 Shore D (Prusament); 95A (Polymaker, ISO 7619-1); 91 Shore A / 40 Shore D (Fiberlogy FiberFlex 40D, ISO 7619); 95A (NinjaTek Cheetah, ASTM D2240); 94.5 A measured on a printed Bambu Lab 95A part and 96.2 A on a Qidi one (My Tech Fun)[4][3][40][38][41]
Creep resistance / sustained load1–5Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[37]Poor — deforms under load at room temperature; a loaded bar crept from 74.5 to 82.7 mm over 5 days[41]
Fatigue / repeated-flex resistance1–5Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[42][36]Excellent — living hinges viable[25]
Elasticity / flexibility1–5Rigid[1]Rubbery / highly elastic[3][4]
Z strength as % of XY%74 at 300 mm/s, 81 at classic speed (printed)[1]Not documented

Flammability / UL 94Flammable; no UL 94 rating published by the major brands[27][2]Flammable; no UL 94 rating published for the grades surveyed[3]
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[36][44]Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[25]
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis[1]Good resistance to oils and common solvents (BASF)[31]
Water / humidity resistance in service1–5Good — insoluble in water[27]Not documented
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[36]Not food safe without specific certification (Polymaker)[25]
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[45][36]Not biodegradable[25]
RecyclabilityMechanically recyclable; not accepted in household plastic collection[45]Not accepted in household plastic collection[25]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[46]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[46]
Ventilation / filtration requirement1–5None needed in a normal room[46]Open a window / occasional ventilation[46]
Post-Processing
Sanding & machiningWet sanding — dry sanding heats the surface by friction and smears it[44][36]Sanding is impractical — the surface tears rather than abrades[25]
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[36][47]Cyanoacrylate bonds TPU; no common solvent welds it[25]
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[36]No practical vapour smoothing[25]
Support material pairingPolySupport and PolyDissolve S1 (Polymaker)[1]Polymaker warns TPU supports are often very difficult to remove; PolyDissolve S1 is rated for TPU[25]
Dimensional accuracy & detailNot documentedStringing and elephant-foot are the accuracy limits; retraction has to be long and slow[3]
Solvents & Solubility
Soluble inChloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[48]DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[49]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[48][50]Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[49]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[51][50]None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[49]
