Enclosure / chamber requirement1–5Enclosure recommended[15]Enclosure required (passive) — Polymaker specifies a 70–100 °C chamber, Bambu Lab 45–60 °C and rules out its P1P and A-series machines[2][5][15]
Recommended chamber temperature°CNot documented70–100 (Polymaker); 45–60 (Bambu Lab)[2][5]
Part cooling fanNot documentedOff or very low — Polymaker specifies off, Prusament 20 % within a 0–30 % range, Bambu Lab 0–60 %[2][4][5]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[15][16]Textured PEI with glue when needed (Polymaker); smooth or textured PEI (Bambu Lab)[2][17]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented24 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 tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[15]Severe — heated chamber needed[2][3][15]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15]Needs a specific surface plus adhesive[2][15]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[19]Moderate — retraction tuning needed[3]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[15]Advanced — enclosure, hardware upgrades, tuning[3][15]
Extruder requirementNot documentedAll-metal hotend rated to 300 °C; Polymaker advises larger nozzles and high chamber temperatures to improve bonding[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[15]Brass fine indefinitely[15]
Abrasiveness1–5Highly abrasive — standard CF composite[15]Non-abrasive[2]
Nozzle clog risk1–5Moderate — 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 sensitivity1–5Slightly sensitive[16]Slightly sensitive[23]
Hotend requirementNo 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)1–5Moderate — 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[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 documented0.25 saturated at 25 °C / 55 % RH (Bambu Lab); 0.15 after 7 days at 24 °C / 22 % RH (Prusa)[5][4]

Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[26]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[26]
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[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 requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[26]Airtight containers with desiccant to prevent reabsorption[3]

Creep resistance / sustained load1–5Good — 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 resistance1–5Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][24]Good[4][3]

Extruded PC stock gives 68.4 (ASTM D696)[6][29]
Flammability / UL 94Not documentedFlammable; no UL 94 rating on standard PC, though V-0 grades exist[32][2]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors — unstabilised PC yellows and embrittles under UV[3]
Chemical resistanceGood 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 service1–5Not documentedGood — minor absorption[5]
Food contactNot food safe — Polymaker cites potential chemical leaching[19]Bisphenol-A polycarbonate is not offered as food-contact filament[3]
Biodegradability / compostabilityNot biodegradable[19]Not biodegradable[3]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[19]Mechanically recyclable but not accepted in household plastic collection[3]
Electrical & ESD propertiesSurface 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 toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[34][15]Moderate — measurable VOCs and UFPs, ventilation advised[34]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34]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[34]≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[34]
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[34][15]Not documented
Ventilation / filtration requirement1–5Enclosure 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 hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[19]Sands and machines well; the toughness means it cuts rather than chips[23]
Painting & finishingPaints readily after light abrasion[19]Optical clarity survives printing, so transparent parts are usually left unpainted[3]
Gluing & solvent weldingNot documentedCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[23]
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[33]No practical vapour smoothing[23]
Support material pairingHIPS 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 & detailNot documentedWarping is the dominant accuracy limit; light transmission 89 % on PolyLite PC (GB/T 2410)[2][3]
Solvents & Solubility
Soluble inAcetone 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 byPetrol 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 agentAcetone 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]
