Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[9]Needs a specific surface plus adhesive[12][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]

Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[9]Hardened steel required[3]
Abrasiveness1–5Highly abrasive — standard GF composite[9]Moderately abrasive — conductive carbon filler[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[16][17]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry[18]

Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[21]Bubbling and popping at the nozzle, stringing and a rough surface[21]
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[21]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][21]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[21]Airtight containers with desiccant to prevent reabsorption[14]
Mechanical Properties
Tensile strength (XY)MPa36 ± 3 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 68 at break[2][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)[3][22][4]
Young's modulusMPa3160 ± 170 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 4210[2][1]2300 (printed XY, ISO 527); Stratasys prints 1960 in XZ and 1810-1910 in ZX (ASTM D638)[3][4]
Elongation at break%6.3 ± 1.2 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 2 at break[2][1]6 at break (printed XY, ISO 527), against 14 for the unfilled grade[3][22]
Flexural strengthMPa68 ± 4 printed XY, ISO 178 (Bambu Lab); 3DXTech quotes 70[2][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)[3][4]
Flexural modulusMPa2860 ± 130 printed XY, ISO 178 (Bambu Lab); 3DXTech quotes 4420[2][1]2310 (printed XY, ISO 178)[3]
Charpy impact, notchedkJ/m²4.2 ± 1.1 printed XY, ISO 179, notched (Bambu Lab)[2]Not documented
Other impact dataCharpy unnotched 14.5 ± 1.5 printed XY (Bambu Lab, ISO 179)[2]Not documented
Layer adhesion / Z tensileMPa29 ± 3 printed Z, ISO 527 (Bambu Lab)[2]32.5-37.9 at yield printed ZX (Stratasys, ASTM D638 on the Fortus 450mc and F900)[4]
Brittleness1–5Brittle — snaps with little warning; notched Charpy falls from 21.5 to 4.2 kJ/m² against unfilled Bambu Lab ABS[2][23]Moderate[3]
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[24]
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 3160 MPa against 2200 for unfilled Bambu Lab ABS[2][23]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[25][4]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; notched Charpy falls to 4.2 kJ/m² against 21.5 for unfilled Bambu Lab ABS[2][23]Not documented

Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[26]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 propertiesNot documentedSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ezPC[3][22]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[27][9]Moderate — measurable VOCs and UFPs, ventilation advised[27]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[27]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[27]≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[27]
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[27][9]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[27][9]Ventilated room or enclosure recommended[27][9]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Sands and machines well; the toughness means it cuts rather than chips[12]
Painting & finishingPaints readily after light abrasion[15]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[12]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[12]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[28][9]Prints its own supports; 3DXTech sells a dedicated PC break-away support[12]
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[29][26]Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[30]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[29][31]Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[30]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[32][26]Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[33]
