Diameter tolerance± mmNot documented±0.04 (Prusament PC Blend Carbon Fiber)[2]
Printing Parameters
Nozzle temperature°CNot documented285 ± 10 (Prusament)[2]
Bed temperature°CNot documented110 ± 10 (Prusament)[2]
Enclosure / chamber requirement1–5Enclosure recommended[12]Enclosure required (passive)[2][12]
Part cooling fanNot documentedOff — Prusa allows 0–20 % and warns cooling significantly reduces interlayer adhesion[2]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[12][13]PEI with a glue stick or a commercial adhesive[14]
Warping tendency1–5High — enclosure needed for reliable large parts[12]High — enclosure needed for reliable large parts; the fibre reduces warping against unfilled PC[2][12]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[12]Needs a specific surface plus adhesive[14][15]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[16]Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[15]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[12]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[12][2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required[12]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Highly abrasive — standard CF composite[12]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[17]High — jams from moisture, heat creep or particles; PC already absorbs water from the air and 3DXTech adds a hardened 0.4 mm minimum nozzle, 0.25 mm layers and a 120 °C pre-dry[18][14][19]
Heat-creep / jam sensitivity1–5Slightly sensitive[13]Slightly sensitive[14]
Hotend requirementNo special hot-end required[13]All-metal hot end required (Simplify3D)[14]
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][17]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][18]
Equilibrium moisture content at ~50 % RH%Not documented0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[2]
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[15][24]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[24]Airtight containers with desiccant to prevent reabsorption[15]
Mechanical Properties
Tensile strength (XY)MPa58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][25]64 ± 3 printed horizontal and 70 ± 3 printed vertical at yield, ISO 527-1 (Prusament); 3DXTech quotes 73 at break[2][3]
Young's modulusMPa2130 (printed XY, ISO 527)[1]2600 printed horizontal and 3200 printed vertical, ISO 527-1 (Prusament); 3DXTech quotes 6980[2][3]
Elongation at break%4 at break (printed XY, ISO 527)[1]4.6 at yield printed horizontal (Prusament); 3DXTech quotes 2.1 at break[2][3]
Flexural strengthMPa80 (printed XY, ISO 178)[1]94 ± 3 printed horizontal and 130 ± 2 printed vertical, ISO 178 (Prusament); 3DXTech quotes 85[2][3]
Flexural modulusMPa2275 (printed XY, ISO 178)[1]3500 printed horizontal and 4200 printed vertical, ISO 178 (Prusament); 3DXTech quotes 6540[2][3]
Charpy impact, notchedkJ/m²Not documented12 ± 1 printed horizontal and 17 ± 2 printed vertical, ISO 179-1 notched (Prusament)[2]
Other impact dataNot documentedCharpy unnotched 32 ± 5 printed horizontal and 35 ± 4 printed vertical (Prusament, ISO 179-1)[2]
Layer adhesion / Z tensileMPaNot documented23 ± 2 (Prusa Polymers interlayer adhesion test) — above the 21 ± 2 of unfilled Prusament PC Blend[2][23]
Brittleness1–5Moderate[1]Moderate[2][3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documented83 Shore D (Prusa Polymers method), against 79 for unfilled Prusament PC Blend[2][23]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1]Excellent — holds load for years. Room-temperature tensile creep of moulded unfilled PC ran unbroken at 41 MPa until the test was stopped; short carbon fibre raises the flexural modulus from about 2.1 to 3.5-6.5 GPa, which reduces creep strain further[26][2]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][25]Good. No fatigue test data was found for a carbon-fibre PC filament; the unfilled polymer is rated Good on the same scale[26]
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Thermal Properties
HDT at 0.45 MPa°CNot documented114 (ISO 75, 0.45 MPa, Prusament)[2]
HDT at 1.8 MPa°CNot documented106 (ISO 75, 1.8 MPa, Prusament), against 93 for unfilled Prusament PC Blend[2][23]
Glass transition (Tg)°C105 (DSC)[1]127 (3DXTech, DSC)[3]
Continuous service temperature°CNot documented113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[23]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors unless stabilised[15]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[27]Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[15]
Food contactNot food safe — Polymaker cites potential chemical leaching[16]Bisphenol-A polycarbonate is not offered as food-contact filament[15]
Biodegradability / compostabilityNot biodegradable[16]Not biodegradable[15]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[16]Mechanically recyclable but not accepted in household plastic collection[15]
Electrical & ESD propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][25]Surface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[28][12]Moderate — measurable VOCs and UFPs, ventilation advised[28]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[28]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[28]≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[28]
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[28][12]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[28][12]Ventilated room or enclosure recommended[28][12]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Carbon fibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[16]Sands and machines well; the toughness means it cuts rather than chips[14]
Painting & finishingPaints readily after light abrasion[16]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[14]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[14]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[29][12]Prints its own supports; 3DXTech sells a dedicated PC break-away support[14]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[30][27]Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[31]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[30][32]Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[31]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[33]Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[34]
