Typical applicationsStiff tooling and fixtures that must survive above 100 °C[1]Electronics fixtures and trays that need PC heat resistance and static dissipation together[2]
Printing Parameters
Enclosure / chamber requirement1–5Enclosure recommended[10]Enclosure required (passive)[10][11]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][12]PEI with a glue stick or a commercial adhesive[13]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[10]Severe — heated chamber needed[10][11]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Needs a specific surface plus adhesive[13][14]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[15]Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[14]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[10]Advanced — enclosure, hardware upgrades, tuning[10]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[10]Hardened steel required[2]
Abrasiveness1–5Highly abrasive — standard CF composite[10]Moderately abrasive — conductive carbon filler[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[16][17][18]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry[19]
Heat-creep / jam sensitivity1–5Slightly sensitive[12]Slightly sensitive[13]
Hotend requirementNo special hot-end required[12]All-metal hot end required (Simplify3D)[13]
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[20][21][16]Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[22][23][19]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[24]Bubbling and popping at the nozzle, stringing and a rough surface[24]
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[24]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[14][24]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[24]Airtight containers with desiccant to prevent reabsorption[14]
Mechanical Properties
Tensile strength (XY)MPa46 at break (printed XY, ISO 527)[1]68 at break (printed XY, ISO 527, 3DXTech) — above the 58 of 3DXTech's unfilled ezPC; Stratasys prints 47.6-49.4 at yield in XZ (ASTM D638)[2][25][3]
Young's modulusMPa5210 (printed XY, ISO 527) — more than double unfilled ABS[1]2300 (printed XY, ISO 527); Stratasys prints 1960 in XZ and 1810-1910 in ZX (ASTM D638)[2][3]
Elongation at break%2 at break (printed XY, ISO 527)[1]6 at break (printed XY, ISO 527), against 14 for the unfilled grade[2][25]
Flexural strengthMPa76 (printed XY, ISO 178)[1]95 (printed XY, ISO 178); Stratasys prints 82.6-83.2 at break in XZ against 46.3-49.5 in ZX (ASTM D790)[2][3]
Flexural modulusMPa5260 (printed XY, ISO 178)[1]2310 (printed XY, ISO 178)[2]
Layer adhesion / Z tensileMPaNot documented32.5-37.9 at yield printed ZX (Stratasys, ASTM D638 on the Fortus 450mc and F900)[3]
Brittleness1–5Brittle — snaps with little warning; elongation at break 2 %[1]Moderate[2]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell 70 (118) — the source does not name the scales and Shore D 79 on extruded unfilled PC stock (ASTM D785, D2240); no figure is published for an ESD grade[26]
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][20][21]Excellent — holds load for years. Moulded unfilled PC was still running unbroken under 41 MPa tensile creep at room temperature when the test was stopped, and the conductive filler leaves the glass transition unchanged at 142 °C, so the creep mechanism is polycarbonate's[27][3]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][20]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Z strength as % of XY%Not documented68-77 (Stratasys ZX against XZ tensile yield, ASTM D638)[3]
Thermal Properties
HDT at 0.45 MPa°CNot documented143-146 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 66 psi); 135 moulded[3]
HDT at 1.8 MPa°CNot documented140-144 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 264 psi); 124 moulded[3]
Glass transition (Tg)°C105 (DSC)[1]143 (DSC, 3DXTech) and 142 (Stratasys, ASTM D7426)[2][3]
Continuous service temperature°CNot documented113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[23]
Thermal expansion (CTE)µm/m·K19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[28]68.4 on extruded unfilled PC stock (ASTM D696; source states 3.8e-5 in/in/°F); no figure is published for a conductive-filled grade[26]
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[29]Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[14]
Food contactNot food safe — Polymaker cites potential chemical leaching[15]Bisphenol-A polycarbonate is not offered as food-contact filament[14]
Biodegradability / compostabilityNot biodegradable[15]Not biodegradable[14]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[15]Mechanically recyclable but not accepted in household plastic collection[14]
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]Surface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ezPC[2][25]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[30][10]Moderate — measurable VOCs and UFPs, ventilation advised[30]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[30]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[30]≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[30]
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[30][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[30][10]Ventilated room or enclosure recommended[30][10]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[2]
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Sands and machines well; the toughness means it cuts rather than chips[13]
Painting & finishingPaints readily after light abrasion[15]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[13]
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[29]No practical vapour smoothing[13]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[31][10]Prints its own supports; 3DXTech sells a dedicated PC break-away support[13]
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[32][29]Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[33]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[32][34]Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[33]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[35][29]Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[36]
