| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 230–260 °C; 240 °C recommended.[2] |
| Bed temperature°C | Not documented | 60–90 °C[2] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[6][7] | Not documented |

| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[8] | PEI build plate[2] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[2] |
| Warping tendency1–5 | Severe — heated chamber needed[6][7] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[8][9] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[9] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[6] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Not documented |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Not documented |

| Heat-creep / jam sensitivity1–5 | Slightly sensitive[8] | Not documented |
| Hotend requirement | All-metal hot end required (Simplify3D)[8] | 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[11][12][10] | Not documented |
| Drying temperature & time | Not documented | 70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[2] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[13] | 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[9][13] | Not documented |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[9] | 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][14][3] | >16.5 MPa printed XY, GB/T 1040; manufacturer lower bound, not an exact measurement.[2] |
| Young's modulusMPa | 2300 (printed XY, ISO 527); Stratasys prints 1960 in XZ and 1810-1910 in ZX (ASTM D638)[1][3] | Not documented |
| Elongation at break% | 6 at break (printed XY, ISO 527), against 14 for the unfilled grade[1][14] | >520% printed XY, GB/T 1040; manufacturer lower bound.[2] |
| 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][3] | Not documented |
| Flexural modulusMPa | 2310 (printed XY, ISO 178)[1] | Not documented |
| Layer adhesion / Z tensileMPa | 32.5-37.9 at yield printed ZX (Stratasys, ASTM D638 on the Fortus 450mc and F900)[3] | 7.5 MPa printed Z, GB/T 1040 (manufacturer test)[2] |
| Brittleness1–5 | Moderate[1] | Not documented |
| 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[15] | 90 Shore A nominal grade designation; do not compare numerically with Shore D or Rockwell.[5] |
| 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[16][3] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |

| HDT at 1.8 MPa°C | 140-144 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 264 psi); 124 moulded[3] | Not documented |
| Glass transition (Tg)°C | 143 (DSC, 3DXTech) and 142 (Stratasys, ASTM D7426)[1][3] | Not documented |
| Melting point / Vicat°C | Not documented | 110 °C Vicat softening (GB/T 1633, 120 °C/h, 10 N); not HDT or a continuous-use rating.[2] |
| Continuous service temperature°C | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[12] | Not documented |
| 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[15] | Not documented |

| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[17] | Not documented |

| 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[8] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[8] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[8] | Not documented |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[8] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[18] | Not documented |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[18] | Not documented |
| Solvent welding & smoothing agent | Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[19] | Not documented |
