| Bed temperature°C | 80–100 (Bambu Lab); 90–100 (Polymaker)[4][1] | Not documented |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][17] | Enclosure required (passive)[3] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[4] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab); off (Polymaker PolyLite)[4][1] | Not documented |

| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[18] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[17] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[17] | Not documented |
| Stringing / oozing tendency1–5 | Slight[1] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[17][1] | Advanced — enclosure, hardware upgrades, tuning[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Not documented |
| Abrasiveness1–5 | Non-abrasive[17] | Not documented |
| Nozzle clog risk1–5 | Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[19][20] | Very high — frequent jams without careful setup[21][22] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[19] | Not documented |
| Hotend requirement | No special hot-end required[19] | Not documented |
| Moisture Behaviour | ||

| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[22] | Not documented |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[22] | Measured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[23][21] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[22] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[4][5][6][24] | 82.7 at yield and 84.8 at break on extruded PA66 stock (ASTM D638; converted from 12,000 and 12,300 psi) — no printed figure exists because no unfilled PA66 filament was found[7] |
| Young's modulusMPa | 2200 ± 190 (Bambu Lab) to 2330 (Polymaker ABS Pro) printed XY, ISO 527; 3DXTech quotes 1950[4][5][24] | 2413 on extruded PA66 stock (ASTM D638; converted from 350,000 psi)[7] |

| Brittleness1–5 | Tough — absorbs impact, yields before breaking[4][1] | Not documented |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Shore D 86 and Rockwell 85 (108) — the source does not name the scales on extruded PA66 stock (ASTM D2240, D785)[7] |
| Creep resistance / sustained load1–5 | Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][5][6] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[4][25] | Excellent — living hinges viable[3] |
| Elasticity / flexibility1–5 | Rigid[4] | Semi-flexible[21] |
| Z strength as % of XY% | 85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[4][5] | Not documented |
| Wear resistance & friction | Not documented | Wear factor 200e-10 in3*min/(ft*lb*h) on extruded PA66 stock (ASTM D3702); Ensinger lists very good slide and wear properties[7] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 87 (Bambu Lab) to 118 (Polymaker ABS Max), ISO 75 at 0.45 MPa; PolyLite ABS 100[4][1][6] | 232 on extruded PA66 stock (ASTM D648 at 66 psi; converted from 450 °F)[7] |
| HDT at 1.8 MPa°C | 84 (Bambu Lab) to 113 (Polymaker ABS Max), ISO 75 at 1.8 MPa; PolyLite ABS 98[4][1][6] | 90 on extruded PA66 stock (ASTM D648 at 264 psi; converted from 194 °F) — the gap to the 0.45 MPa figure is the widest in the dataset[7] |
| Glass transition (Tg)°C | 101 (PolyLite) to 126 (ABS Max), DSC; 105 quoted by 3DXTech[1][6][24] | Not documented |
| Melting point / Vicat°C | Amorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][6] | 255 melting on extruded PA66 stock (ASTM D2133; converted from 491 °F)[7] |

| Water / humidity resistance in service1–5 | Good — minor absorption[4] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[16] | Not documented |
| Biodegradability / compostability | Not biodegradable[16] | Not documented |
| Recyclability | Mechanically recyclable as resin code 9, but not accepted in household plastic collection[16] | Not documented |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[24] | Volume resistance 1e15 ohm-cm and dielectric constant 4 on extruded PA66 stock (ASTM D257, D150)[7] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[30][17] | Moderate — measurable VOCs and UFPs, ventilation advised[30] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[30] | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[30] |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[30] | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[30] |
| Hazardous species emitted | Styrene 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[30][17] | Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[30] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[30][17] | Ventilated room or enclosure recommended[30] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[16] | Not documented |
| Gluing & solvent welding | Solvent-welds with acetone[1] | Not documented |
| Vapour / chemical smoothing | Acetone vapour smoothing works — ABS dissolves in acetone[1] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[31][17] | Not documented |
| Dimensional accuracy & detail | Warping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[17] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[32][1] | Dissolved at 23 °C by formic acid above ~80 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[33] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[32][34] | Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[33] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[35] | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[33] |
