Market availability1–5Available from several mainstream brands[6][7][8]Ubiquitous, every brand and retailer[9][15][10][14][11][12]
Spool sizes & diameters1.75 and 2.85 mm; 700 g, 850 g and 2.2 kg spools[6][7][8]1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[9][15]
Typical applicationsStiff, chemically resistant parts where PP-CF's cost or conductivity is unwanted[2]Gaskets, phone cases, tyres, vibration mounts and protective covers[19]
Diameter tolerance± mm±0.04 (Prusament)[1]±0.06 (Prusament) — the loosest tolerance Prusa publishes, because soft filament deforms in the gauge[4]
Printing Parameters
Nozzle temperature°C245 ± 10 (Prusament) — 25 °C below the carbon-fibre grade[1][20]210–240; Polymaker 210–230, Prusament 230 ± 10, Bambu Lab HF 220–240[3][4][5]
Bed temperature°C95 ± 10 (Prusament)[1]25–65; Prusament 65 ± 10, Bambu Lab 30–35, Polymaker 25–60[4][5][3]
Enclosure / chamber requirement1–5Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[21][22]Open frame is fine[3]
Part cooling fanOff — Prusa runs 0 % except 100 % on bridges[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[23][19]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][24]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 tendency1–5High — enclosure needed for reliable large parts; Prusa recommends a brim[1]None[3]
Bed-adhesion difficulty1–5Very difficult — special plates or slurry required[1]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 difficulty1–5Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[1]Intermediate — dry filament and a tuned profile; the speed ceiling is the main constraint[3][4]
Extruder requirementPrusa states a hardened nozzle is necessary and recommends a brim[1]Direct 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[25][3][4]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely[26]
Abrasiveness1–5Highly abrasive — standard GF composite[1]Non-abrasive[26]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[27]Moderate — needs dry filament and a clean nozzle[28]
Heat-creep / jam sensitivity1–5Not documentedHigh — all-metal hotend and strong cooling needed; soft filament buckles in the cold zone if it slows[19]
Hotend requirementNot documentedNo special hot-end required, but a direct-drive extruder is (Simplify3D)[23]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — 0.11 % at both 24 h and 7 days, higher than the carbon-fibre grade's 0.04 % but still very low[1][20]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][28]
Equilibrium moisture content at ~50 % RH%0.11 after 24 h and 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[1]0.82 equilibrium (Polymaker); 0.02 after 24 h and 0.04 after 7 days at 22 % RH (Prusa)[3][4]
Drying temperature & timeNot documented70 °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 wetNot documentedBubbling and popping at the nozzle, stringing, rough surface and weak layers[28]
Effect of moisture on strengthNot applicable in practice at 0.11 % equilibrium uptake[1]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[28]
Storage requirementNo special storage needed[1]Sealed with desiccant; often kept in a dryer during the print[28]
Mechanical Properties
Tensile strength (XY)MPa46.6 ± 1.3 filament tensile yield (Prusament, ISO 527) — more than double the carbon-fibre grade's 21[1][20]41.4 ± 1.3 printed (Prusament, ISO 37); NinjaTek Cheetah 39 ultimate (ASTM D638)[4][29]
Elongation at break%Not documented551 ± 24 printed (Polymaker, ISO 37); the filament itself stretches 7264 % before break (Prusa, ISO 527)[3][4]
Charpy impact, notchedkJ/m²7.9 ± 0.4 printed horizontal and 9.9 ± 0.8 printed vertical XZ (ISO 179-1, notched)[1]Not documented
Layer adhesion / Z tensileMPaNot documented9.5 ± 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 / RockwellRockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a glass-fibre PP filament[30]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][31][29][32]
Creep resistance / sustained load1–5Not documentedPoor — deforms under load at room temperature; a loaded bar crept from 74.5 to 82.7 mm over 5 days[32]
Fatigue / repeated-flex resistance1–5Not documentedExcellent — living hinges viable[19]
Elasticity / flexibility1–5Rigid[1]Rubbery / highly elastic[3][4]
Wear resistance & frictionNot documentedAbrasion resistance is a headline property; BASF measures 64 mm³ loss by ISO 4649 on its 92A grade[25]
Thermal Properties
HDT at 0.45 MPa°C138.3 (ISO 75, 0.45 MPa)[1]Not documented
HDT at 1.8 MPa°C112.6 (ISO 75, 1.8 MPa)[1]Not documented
Melting point / Vicat°CNot documented144 melting (BASF 95A, ISO 11357-3); Bambu Lab 183, Polymaker's modulus at 100 % elongation 8.9 MPa[25][5]
Continuous service temperature°CNot documentedBounded by a melting point of 144–183 °C; no loaded-bar service figure is published for TPU[25][5]
Flammability / UL 94Not documentedFlammable; no UL 94 rating published for the grades surveyed[3]
Environment & Chemical
UV resistance1–5Not documentedGood — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[19]
Chemical resistanceExcellent against acids, alkalis and most solvents[22]Good resistance to oils and common solvents (BASF)[25]
Water / humidity resistance in service1–5Excellent — essentially unaffected[1]Not documented
Food contactNot documentedNot food safe without specific certification (Polymaker)[19]
Biodegradability / compostabilityNot documentedNot biodegradable[19]
RecyclabilityNot documentedNot accepted in household plastic collection[19]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[33]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[33]
Ventilation / filtration requirement1–5Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[33]Open a window / occasional ventilation[33]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningNot documentedSanding is impractical — the surface tears rather than abrades[19]
Gluing & solvent weldingNot documentedCyanoacrylate bonds TPU; no common solvent welds it[19]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[19]
Support material pairingNot documentedPolymaker warns TPU supports are often very difficult to remove; PolyDissolve S1 is rated for TPU[19]
Dimensional accuracy & detailNot documentedStringing and elephant-foot are the accuracy limits; retraction has to be long and slow[3]
Solvents & Solubility
Soluble inNone at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[34][35]DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[36]
Softened or crazed byXylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[34]Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[36]
Solvent welding & smoothing agentNone — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[34]None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[36]
