| Bed temperature°C | 80–100 (Bambu Lab); 90–100 (Polymaker)[4][1] | 60 (Proto-pasta)[3] |
| 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] | Open frame is fine[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 |
| Bed surface & adhesion aid | Clean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[17] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[18] | 1.6–2.4 at Proto-pasta's 20–30 mm/s on a 0.4 mm nozzle at 0.2 mm layer[3] |
| 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] | Intermediate — dry filament and a tuned profile; slow, and brittle in filament form[3] |
| Extruder requirement | Not documented | Proto-pasta advises an extrusion width 0.05 mm larger than the nozzle and warns feeding is inconsistent below 0.4 mm and on Bowden machines[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Brass acceptable; hardened steel for volume work[3] |
| Abrasiveness1–5 | Non-abrasive[17] | Moderately abrasive — metal fill[3] |
| 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] | Moderate — needs dry filament and a clean nozzle; Prusa lists metal-filled composites as a higher clogging risk and recommends a 0.6 mm nozzle minimum[21] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[19] | Not documented |
| Hotend requirement | No special hot-end required[19] | Proto-pasta recommends a wear-resistant or larger nozzle for longer service intervals[3] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[4][5] | Not documented |
| Equilibrium moisture content at ~50 % RH% | 0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[4][5] | Not documented |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[4][1] | Not documented |
| 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] | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[22] |
| 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][23] | Not documented |
| Young's modulusMPa | 2200 ± 190 (Bambu Lab) to 2330 (Polymaker ABS Pro) printed XY, ISO 527; 3DXTech quotes 1950[4][5][23] | Not documented |

| Brittleness1–5 | Tough — absorbs impact, yields before breaking[4][1] | Brittle — Proto-pasta describes the filament as more brittle than standard PLA and needing extra care in handling[3] |
| 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][24] | Not documented |
| Elasticity / flexibility1–5 | Rigid[4] | Rigid[3] |
| Z strength as % of XY% | 85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[4][5] | Not documented |

| Annealing response | Decomposition above 380 °C (PolyLite ABS, TGA)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 86 ± 3 at 0° and 89 ± 3 at 90° raster (printed, fibre Bragg grating, 25–50 °C); 82 for a neat large-format bead at 30 °C[26][27] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[28][4] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[16] | Not documented |
| Outdoor durability | Not documented | Deliberately rustable — Proto-pasta markets the iron content as oxidising when exposed to moisture[3] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1] | Not documented |
| 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)[23] | Ferromagnetic: Proto-pasta states it responds to magnets and behaves similarly to pure iron[3] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[29][17] | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[29] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[29] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[29] | Not documented |
| 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[29][17] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[29][17] | Open a window / occasional ventilation[29] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[16] | Polishing and deliberate rusting are the intended finishes[3] |
| 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[30][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.[31][1] | Chloroform dissolves the PLA matrix and leaves the iron powder behind; laboratory reagent, not workshop stock.[32][3] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[31][33] | Acetone and ethyl acetate plasticise the matrix rather than dissolving it; water attacks the exposed iron.[32][3] |
| 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.[34] | None — PLA has no workshop-safe solvent, and the iron loading blocks the surface flow smoothing needs.[32] |
