| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 24 at Bambu Lab's 300 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer; Polymaker allows 50–200 mm/s and its material guide advises 30–60 for layer adhesion[5][2][3][18] |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[15] | Severe — heated chamber needed[2][3][15] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[15] | Needs a specific surface plus adhesive[2][15] |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[19] | Moderate — retraction tuning needed[3] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[15] | Advanced — enclosure, hardware upgrades, tuning[3][15] |
| Extruder requirement | Not documented | All-metal hotend rated to 300 °C; Polymaker advises larger nozzles and high chamber temperatures to improve bonding[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[15] | Brass fine indefinitely[15] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[15] | Non-abrasive[2] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[20][21][22] | Moderate — needs dry filament and a clean nozzle[3] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[16] | Slightly sensitive[23] |
| Hotend requirement | No special hot-end required[16] | All-metal hot end required (Simplify3D); Polymaker advises a hot end rated above 300 °C[23][3] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 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[24][25][20] | Low — 0.25 % saturated at 25 °C / 55 % RH (Bambu Lab); Prusa measures 0.15 % after 7 days at 22 % RH. Polymaker nonetheless calls PC highly hygroscopic in service[5][4][3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.25 saturated at 25 °C / 55 % RH (Bambu Lab); 0.15 after 7 days at 24 °C / 22 % RH (Prusa)[5][4] |

| Effect of moisture on strength | Polymaker 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[26] | No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[3][26] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[26] | Airtight containers with desiccant to prevent reabsorption[3] |

| Young's modulusMPa | 5210 (printed XY, ISO 527) — more than double unfilled ABS[1] | 2110 (Bambu Lab) to 2497 (PolyLite) printed XY, ISO 527; Prusament 1900, 3DXTech 2180[5][2][4][28] |
| Elongation at break% | 2 at break (printed XY, ISO 527)[1] | 3.8 (Bambu Lab) to 4.8 (PolyLite) at break, printed XY, ISO 527; 3DXTech quotes 14 at break, Prusament 5.8 at yield[5][2][28][4] |

| Layer adhesion / Z tensileMPa | Not documented | 37.1-45.3 at yield printed ZX (Stratasys PC Black and Red, ASTM D638); 41.4 (PolyMax) to 56 (Bambu Lab) printed Z; Prusa's interlayer adhesion test gives 21 +/- 2[4][27][5][6] |

| Creep resistance / sustained load1–5 | Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][24][25] | Excellent — holds load for years. Room-temperature tensile creep of moulded PC was still running unbroken at 41 MPa when the experiment was stopped for time; specimens failed within the test window only at 47-52 MPa (ASTM D638)[30] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][24] | Good[4][3] |

| Melting point / Vicat°C | Not documented | Amorphous — no melting point; Vicat 117–120 (Polymaker, ISO 306); decomposition above 360 °C[2][27] |
| Continuous service temperature°C | Not documented | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend; extruded PC stock is rated 121 long term (converted from 250 °F)[4][29] |
| Annealing response | Not documented | 90 °C for 2 h (Polymaker)[2] |
| Thermal expansion (CTE)µm/m·K | 19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[31] | 51.6 in XY over -50 to 30 °C, falling to 35.8 over 30-75 °C and 11.5 over 75-130 °C; 49.2 in XZ over -50 to 120 °C (printed, ASTM E831). Extruded PC stock gives 68.4 (ASTM D696)[6][29] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating on standard PC, though V-0 grades exist[32][2] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors — unstabilised PC yellows and embrittles under UV[3] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[33] | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[3] |
| Water / humidity resistance in service1–5 | Not documented | Good — minor absorption[5] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[19] | Bisphenol-A polycarbonate is not offered as food-contact filament[3] |
| Biodegradability / compostability | Not biodegradable[19] | Not biodegradable[3] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[19] | Mechanically recyclable but not accepted in household plastic collection[3] |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1] | Surface resistance above 10¹³ ohm/sq — an electrical insulator, which Polymaker lists as a headline advantage[28][3] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[34][15] | Moderate — measurable VOCs and UFPs, ventilation advised[34] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34] | 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[34] | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[34] |
| 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[34][15] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][15] | Ventilated room or enclosure recommended[34][15] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[19] | Sands and machines well; the toughness means it cuts rather than chips[23] |
| Painting & finishing | Paints readily after light abrasion[19] | Optical clarity survives printing, so transparent parts are usually left unpainted[3] |
| Gluing & solvent welding | Not documented | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[23] |
| Vapour / chemical smoothing | Acetone smoothing is blunted by the fibre — only the resin fraction dissolves[33] | No practical vapour smoothing[23] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][15] | Prints its own supports; 3DXTech sells a dedicated PC break-away support[23] |
| Dimensional accuracy & detail | Not documented | Warping is the dominant accuracy limit; light transmission 89 % on PolyLite PC (GB/T 2410)[2][3] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[36][33] | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[37] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[36][38] | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[37] |
| Solvent welding & smoothing agent | Acetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[39][33] | Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[40] |
