Identity & Market
Base polymer / chemistryABS reformulated for lower warping and a higher glass transition; Polymaker's ABS Pro and ABS Max reach Tg 114.9 and 126.3 °C against 101 °C for PolyLite ABS[1][2][3]Thermoplastic polyurethane, polyester or polyether based, at about 92–95 Shore A[4][5]

Market availability1–5Available from several mainstream brands[7]Ubiquitous, every brand and retailer[7][15][8][14][9][10]
Spool sizes & diameters1.75 and 2.85 mm; 1 kg spools[7]1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[7][15]
Typical applicationsLarge enclosure and automotive parts where plain ABS warps or softens too early[1][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[5]
Printing Parameters
Nozzle temperature°C270–290 (ABS Pro); 270–300 (ABS Max) — 25–35 °C above plain ABS[1][2]210–240; Polymaker 210–230, Prusament 230 ± 10, Bambu Lab HF 220–240[4][5][6]
Bed temperature°C120 (ABS Max)[2]25–65; Prusament 65 ± 10, Bambu Lab 30–35, Polymaker 25–60[5][6][4]
Enclosure / chamber requirement1–5Enclosure required (passive)[1][2][20]Open frame is fine[4]
Part cooling fanNot documentedFan on[4][6]
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/sUp to 250 mm/s (ABS Pro) and 200 mm/s (ABS Max), equivalent to 20 and 16 on a 0.4 mm nozzle at 0.2 mm layer[1][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)[4][5][6]
Warping tendency1–5High — enclosure needed for reliable large parts[20]None[4]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Sticks to most surfaces[4]
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[4]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Intermediate — dry filament and a tuned profile; the speed ceiling is the main constraint[4][5]
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][4][5]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20]Brass fine indefinitely[26]
Abrasiveness1–5Non-abrasive[20]Non-abrasive[26]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[21][27]Moderate — needs dry filament and a clean nozzle[28]
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 — 0.51 % maximum water absorption (ABS Pro)[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[5][4][28]
Equilibrium moisture content at ~50 % RH%0.51 maximum water absorption (Polymaker ABS Pro)[1]0.82 equilibrium (Polymaker); 0.02 after 24 h and 0.04 after 7 days at 22 % RH (Prusa)[4][5]
Drying temperature & time70 °C for 6 h (ABS Max)[2]70 °C for 8 h (Polymaker); 70 °C for 8 h or an 80–90 °C heatbed for 12 h (Bambu Lab)[4][6]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[28]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[28]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures[28]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 requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[28]Sealed with desiccant; often kept in a dryer during the print[28]
Mechanical Properties
Tensile strength (XY)MPa34.9 (ABS Pro) and 35.7 (ABS Max) printed XY, ISO 527[1][2]41.4 ± 1.3 printed (Prusament, ISO 37); NinjaTek Cheetah 39 ultimate (ASTM D638)[5][29]

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)[5][4][30][29][31]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 115 °C (ABS Pro) and 126 °C (ABS Max) keeps room-temperature service far below softening[1][2]Poor — deforms under load at room temperature; a loaded bar crept from 74.5 to 82.7 mm over 5 days[31]
Fatigue / repeated-flex resistance1–5Moderate — no S-N curve found; 6.7–7.3 % elongation and 10.5–14.5 kJ/m² notched Charpy, below unfilled Bambu Lab ABS[1][2][32]Excellent — living hinges viable[19]

Flammability / UL 94Not documentedFlammable; no UL 94 rating published for the grades surveyed[4]
Environment & Chemical

Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]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[34][20]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[34]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34]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[34]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[34][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][20]Open a window / occasional ventilation[34]
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 smoothingAcetone vapour smoothing works[3]No practical vapour smoothing[19]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][20]Polymaker 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[4]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[36][3]DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[37]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[36][38]Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[37]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[39]None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[37]
