| 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][25] | Open frame fine; draught shield helps — Bambu Lab specifies a 35–50 °C chamber[3] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[5] | 35–50 (Bambu Lab)[3] |
| Part cooling fan | 0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1] | 0–60 % (Bambu Lab); 50 % (Prusament)[3][4] |
| Bed surface & adhesion aid | Clean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[25] | Textured PEI or engineering plate with glue (Bambu Lab)[3] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[26] | 11.5 on My Tech Fun's Bambu Lab PETG-CF profile[27] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[25] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[25] | Needs the right surface or a thin adhesive[3] |
| Stringing / oozing tendency1–5 | Slight[1] | Slight — the fibre reduces stringing against unfilled PETG[3][28] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[25][1] | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[25] | Hardened steel required[3] |
| Abrasiveness1–5 | Non-abrasive[25] | Highly abrasive — standard CF composite[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[29][30] | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[31][32] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[29] | Slightly sensitive[28] |
| Hotend requirement | No special hot-end required[29] | Hardened steel nozzle; no high-temperature hot-end needed[3][28] |
| 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[5][6] | Low — 0.30 % saturated at 25 °C / 55 % RH (Bambu Lab)[3] |
| Equilibrium moisture content at ~50 % RH% | 0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6] | 0.30 saturated at 25 °C / 55 % RH (Bambu Lab); Prusa measures 0.10 after 7 days at 22 % RH[3][4] |

| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[33] | Bubbling and popping at the nozzle, stringing and a rough surface[33] |
| 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[33] | No dry-versus-conditioned figures published; Bambu Lab states PETG-CF must be properly dried before printing and stored dry after use[3][33] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[33] | Sealed with desiccant; Bambu Lab says store dry after use[3][33] |

| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 77 Shore D (Prusa Polymers method)[4] |
| 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][6][7] | Below average — a 12 mm bar sagged to 16.4 mm over 5 days at 1.25 kg, less than plain PETG's 19.4[27] |
| 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[5][35] | Moderate — no CF-grade S-N curve; unfilled printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[35] |

| Melting point / Vicat°C | Amorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][7] | 225 melting (Bambu Lab, DSC) — the carbon fibre lets the PET fraction crystallise[3] |
| Continuous service temperature°C | 101 measured on a loaded glass-filled ABS bar (My Tech Fun); unfilled ABS is bounded by its 84–98 °C heat deflection[36][5][1] | 77 — loaded bars begin to move at this temperature, against 61 for Bambu Lab PETG Basic[27] |
| 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[37][38] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[39][5] | Flammable; no UL 94 rating published[3] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[24] | Moderate — a season or two; the carbon fibre does not add UV stabilisation[40] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1] | Withstands acids, alkalis, oils and UV exposure, as for unfilled PETG[40] |
| Water / humidity resistance in service1–5 | Good — minor absorption[5] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[24] | Not certified for food contact[40] |
| Biodegradability / compostability | Not biodegradable[24] | Not biodegradable[40] |
| Recyclability | Mechanically recyclable as resin code 9, but not accepted in household plastic collection[24] | Fibre-filled PETG is not accepted in household plastic collection[40] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[34] | Surface resistance above 10⁹ ohm/sq — carbon fibre at this loading is not static-dissipative (3DXTech)[8] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[41][25] | Moderate — measurable VOCs and UFPs, ventilation advised[41] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[41] | 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[41] | 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[41][25] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[41][25] | Open a window / occasional ventilation[41] |
| Dust & fibre handling hazard | Not documented | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[8] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[24] | Sands to a matte finish more readily than unfilled PETG[28] |
| Gluing & solvent welding | Solvent-welds with acetone[1] | Cyanoacrylate; no common solvent welds it[28] |
| Vapour / chemical smoothing | Acetone vapour smoothing works — ABS dissolves in acetone[1] | No practical vapour smoothing[28] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[42][25] | Support for PLA or its own material (Bambu Lab)[3] |
| Dimensional accuracy & detail | Warping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[25] | Matte finish hides layer lines; stringing is reduced against unfilled PETG[3] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[43][1] | No common workshop solvent; dichloromethane — a carcinogen — dissolves the matrix surface, 1,2-dichloroethane destroys it in a week.[44][45] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[43][46] | Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[44] |
| 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.[45] | Dichloromethane reaches only the resin, so the fibre is left standing proud of the surface. Controlled carcinogen.[45] |
