Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented≈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[2][15][17][22]
Warping tendency1–5High — enclosure needed for reliable large parts[20]None[2]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Sticks to anything[23]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[24]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[20]Easy — minor profile tuning; needs a printer that can actually reach the flow rate[15][2]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20]Brass fine indefinitely[25]
Abrasiveness1–5Non-abrasive[1]Non-abrasive[26][25]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its FR-ABS, only an 80 °C pre-dry[27]Very low[25]
Heat-creep / jam sensitivity1–5Slightly sensitive[21]Moderate — good heatbreak cooling needed; PLA softens below 60 °C[28]
Hotend requirementNo special hot-end required[21]No special hot-end required[23]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[4][29][27]Moderate — 0.40 % equilibrium at 23 °C / 70 % RH[2]
Equilibrium moisture content at ~50 % RH%Not documented0.40 equilibrium at 23 °C / 70 % RH (Polymaker PolySonic)[2]
Drying temperature & timeNot documented55 °C for 6 h; 50 °C for 8 h (Bambu Lab)[2][19]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[30]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[30]
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[30]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[30]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[30]Sealed with desiccant below 20 % RH; shelf life at ambient is long[19][23]
Mechanical Properties
Tensile strength (XY)MPa45 at break (printed XY, ISO 527)[1]43.9 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[2][31]

Layer adhesion / Z tensileMPaNot documented32.4 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[2][31]
Brittleness1–5Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][32]Moderate[2]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documented78.7 Shore D measured on printed bars for Sunlu PLA Meta (My Tech Fun), against 75.3 for the same maker's plain PLA[33]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][32]Poor — 12 mm bar sagged to 17.7 mm over 6 days at 1.25 kg[31]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][32]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[34][28]

Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[37]Good against weak acids, oils and grease; poor against strong acids and alkalis[2]
Water / humidity resistance in service1–5Not documentedGood — insoluble in water[19]
Food contactNot food safe — Polymaker cites potential chemical leaching[24]Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[28]
Biodegradability / compostabilityNot biodegradable[24]Industrially compostable only — needs sustained 55 °C; not home compostable[38][28]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[24]Mechanically recyclable; not accepted in household plastic collection[38]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[39][20]Low hazard — minimal VOC and particle emission[39]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[39]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[39]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[39][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[39][20]None needed in a normal room[39]
Post-Processing
Sanding & machiningSands well and takes filler before painting[24]Wet sanding — dry sanding heats the surface by friction and smears it[36][28]
Painting & finishingPaints readily after light abrasion[24]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[28][40]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[28]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[41][20]PolySupport and PolyDissolve S1 (Polymaker)[2]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[42][37]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[43]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[42][44]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[43][45]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[45]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[46][45]
