Market availability1–5Available from several mainstream brands[6][7]Ubiquitous, every brand and retailer[10][7][11][15][12][13]
Spool sizes & diameters1.75 and 2.85 mm; 750 g and 1 kg spools[7][6]1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[10][7]
Typical applicationsStiff, dimensionally stable enclosure and tooling parts; Bambu Lab notes the fibre blurs layer lines into a matte finish[2]Gaskets, phone cases, tyres, vibration mounts and protective covers[19]
Diameter tolerance± mmNot documented±0.06 (Prusament) — the loosest tolerance Prusa publishes, because soft filament deforms in the gauge[4]
Printing Parameters
Nozzle temperature°C240–280 (Bambu Lab)[2]210–240; Polymaker 210–230, Prusament 230 ± 10, Bambu Lab HF 220–240[3][4][5]
Bed temperature°C80–100 (Bambu Lab)[2]25–65; Prusament 65 ± 10, Bambu Lab 30–35, Polymaker 25–60[4][5][3]
Enclosure / chamber requirement1–5Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[2][20]Open frame is fine[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[2]Not documented
Part cooling fan0–80 % (Bambu Lab)[2]Fan on[3][5]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[20][21]PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[22][19]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][23]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 tendency1–5Moderate — needs adhesion aid or draught shield; Bambu Lab positions the fibre as reducing warping[2]None[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Sticks to most surfaces[3]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[24]Moderate — retraction tuning needed; Polymaker specifies 3–6 mm retraction, well above the 1–3 mm used for rigid filaments[3]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[20]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[25][3][4]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[20]Brass fine indefinitely[26]
Abrasiveness1–5Highly abrasive — standard GF composite[20]Non-abrasive[26]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[27][28]Moderate — needs dry filament and a clean nozzle[29]
Heat-creep / jam sensitivity1–5Slightly sensitive[21]High — all-metal hotend and strong cooling needed; soft filament buckles in the cold zone if it slows[19]
Hotend requirementNo special hot-end required[21]No special hot-end required, but a direct-drive extruder is (Simplify3D)[22]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.53 % saturated at 25 °C / 55 % RH (Bambu Lab)[2]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][29]
Equilibrium moisture content at ~50 % RH%0.53 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.82 equilibrium (Polymaker); 0.02 after 24 h and 0.04 after 7 days at 22 % RH (Prusa)[3][4]
Drying temperature & time80 °C for 8 h (Bambu Lab)[2]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 and a rough surface[29]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[29]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[29]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[29]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[29]Sealed with desiccant; often kept in a dryer during the print[29]

Brittleness1–5Brittle — snaps with little warning; notched Charpy falls from 21.5 to 4.2 kJ/m² against unfilled Bambu Lab ABS[2][31]Very ductile — bends far before failing[3][4]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documented92 ± 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][32][30][33]
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 3160 MPa against 2200 for unfilled Bambu Lab ABS[2][31]Poor — deforms under load at room temperature; a loaded bar crept from 74.5 to 82.7 mm over 5 days[33]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; notched Charpy falls to 4.2 kJ/m² against 21.5 for unfilled Bambu Lab ABS[2][31]Excellent — living hinges viable[19]
Elasticity / flexibility1–5Rigid[2]Rubbery / highly elastic[3][4]
Z strength as % of XY%81 (Bambu Lab, printed Z against XY tensile)[2]Not documented

Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[34]Good resistance to oils and common solvents (BASF)[25]
Food contactNot food safe — Polymaker cites potential chemical leaching[24]Not food safe without specific certification (Polymaker)[19]
Biodegradability / compostabilityNot biodegradable[24]Not biodegradable[19]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[24]Not accepted in household plastic collection[19]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[35][20]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[35]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[35]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[35]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[35][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[35][20]Open a window / occasional ventilation[35]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[24]Sanding is impractical — the surface tears rather than abrades[19]
Painting & finishingPaints readily after light abrasion[24]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate bonds TPU; no common solvent welds it[19]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[19]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[36][20]Polymaker warns TPU supports are often very difficult to remove; PolyDissolve S1 is rated for TPU[19]
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Stringing and elephant-foot are the accuracy limits; retraction has to be long and slow[3]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[37][34]DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[38]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[37][39]Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[38]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[40][34]None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[38]
