| Typical applications | Electronics fixtures and trays that need PC heat resistance and static dissipation together[1] | Chemical-plant and under-bonnet parts needing solvent resistance above 200 °C[3] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 335-345 (3DXTech printed-specimen conditions); 300-330 (Spectrum)[2][5] |
| Bed temperature°C | Not documented | 110-130 (3DXTech); 100-120 (Spectrum)[2][5] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[9][10] | Actively heated chamber required[11][12] |
| Recommended chamber temperature°C | Not documented | 60-80 actively heated (Spectrum PPS AM230)[5] |
| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[13] | Adhesive required — Spectrum specifies Magigoo Pro HT[5] |
| Warping tendency1–5 | Severe — heated chamber needed[9][10] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[13][14] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[14] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[9] | Expert / industrial hardware only[11][12] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[11] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Non-abrasive when unfilled[2] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry[15] | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 110 °C pre-dry before every print[16] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[13] | Not documented |
| Hotend requirement | All-metal hot end required (Simplify3D)[13] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[17][18][15] | Negligible (<0.1 % EMC) — Polymaker states minimal water absorption at 0.05 %[3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.01 in 24 h on extruded stock (ASTM D570) — effectively non-absorbing[19] |
| Drying temperature & time | Not documented | At least 3 h at 90 °C in hot dry air if the filament has taken up moisture (Spectrum)[5] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[20] | Not documented |
| Effect of moisture on strength | 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][20] | Little to measure — equilibrium uptake is 0.05 %; 3DXTech still specifies a 110 °C, 4 h pre-dry before printing[3][16] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[14] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 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)[1][21][4] | 50 at break (printed XY, ISO 527, 3DXTech); 65 at break injection-moulded (ISO 527, Spectrum); 94 at yield on extruded stock (ASTM D638)[2][5][19] |
| Young's modulusMPa | 2300 (printed XY, ISO 527); Stratasys prints 1960 in XZ and 1810-1910 in ZX (ASTM D638)[1][4] | 2650 (printed XY, ISO 527, 3DXTech); 3650 injection-moulded (ISO 527, Spectrum); 5769 on extruded stock (ASTM D638)[2][5][19] |
| Elongation at break% | 6 at break (printed XY, ISO 527), against 14 for the unfilled grade[1][21] | 18 at break (printed XY, ISO 527, 3DXTech) against 2.0 injection-moulded (Spectrum) and 2.5 on extruded stock — the suppliers disagree by nearly an order of magnitude[2][5][19] |
| Flexural strengthMPa | 95 (printed XY, ISO 178); Stratasys prints 82.6-83.2 at break in XZ against 46.3-49.5 in ZX (ASTM D790)[1][4] | 52 (printed XY, ISO 178, 3DXTech); 141 on extruded stock (ASTM D790)[2][19] |
| Flexural modulusMPa | 2310 (printed XY, ISO 178)[1] | 2540 (printed XY, ISO 178)[2] |

| Brittleness1–5 | Moderate[1] | Moderate[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell 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[22] | Rockwell 105 (and R124) on extruded PPS stock (ASTM D785)[19] |
| Creep resistance / sustained load1–5 | 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[23][4] | Excellent — holds load for years. Ensinger lists high creep resistance as a headline property of extruded PPS stock, and Spectrum states that rigidity, strength and creep resistance are unchanged under continuous load at high temperature[19][5] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[2] |
| Z strength as % of XY% | 68-77 (Stratasys ZX against XZ tensile yield, ASTM D638)[4] | Not documented |

| Melting point / Vicat°C | Not documented | 283 melting (ISO 11357, 3DXTech) and 280 on extruded stock; Vicat softening 236 at 50 N injection-moulded (ISO 306, Spectrum)[2][5][19] |
| Continuous service temperature°C | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[18] | 170 long-term service on extruded PPS stock, converted from 338 °F[19] |
| Thermal expansion (CTE)µm/m·K | 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[22] | 59.4 (extruded PPS stock, 22-60 °C, ASTM D696; source states 3.3e-5 in/in/°F)[19] |
| Flammability / UL 94 | Not documented | UL 94 V-0 at 1.5 mm, rated on the base resin[2] |

| Food contact | Bisphenol-A polycarbonate is not offered as food-contact filament[14] | Not documented |
| Biodegradability / compostability | Not biodegradable[14] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[14] | Not documented |
| Electrical & ESD properties | Surface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ezPC[1][21] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[24] | Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[24] |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[24] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[24][9] | Ventilated room or enclosure recommended[24] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands and machines well; the toughness means it cuts rather than chips[13] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[13] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[13] | Not documented |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[13] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[25] | None — PPS does not dissolve in any known solvent below 200 °C.[26][27] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[25] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[27] |
| Solvent welding & smoothing agent | Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[28] | None — no solvent welds or smooths PPS.[26] |
