| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 24 at Bambu Lab's 300 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer; Polymaker allows 50–200 mm/s and its material guide advises 30–60 for layer adhesion[5][1][2][18] | Not documented |
| Warping tendency1–5 | Severe — heated chamber needed[1][2][14] | Severe — heated chamber needed[15] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[1][14] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[2] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[2][14] | Expert / industrial hardware only[15][16] |
| Extruder requirement | All-metal hotend rated to 300 °C; Polymaker advises larger nozzles and high chamber temperatures to improve bonding[2] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[14] | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[15] |
| Abrasiveness1–5 | Non-abrasive[1] | Non-abrasive when unfilled[3] |

| Hotend requirement | All-metal hot end required (Simplify3D); Polymaker advises a hot end rated above 300 °C[20][2] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low — 0.25 % saturated at 25 °C / 55 % RH (Bambu Lab); Prusa measures 0.15 % after 7 days at 22 % RH. Polymaker nonetheless calls PC highly hygroscopic in service[5][4][2] | Not documented |
| Equilibrium moisture content at ~50 % RH% | 0.25 saturated at 25 °C / 55 % RH (Bambu Lab); 0.15 after 7 days at 24 °C / 22 % RH (Prusa)[5][4] | 0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[21] |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 75 °C for 6 h (Polymaker); 70–80 °C for 6–8 h (Polymaker material guide)[5][1][2] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[22] | 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[2][22] | No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[19] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[2] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 53.4 (PolyMax) to 69.1 (PolyLite) printed XY, ISO 527; Bambu Lab 62 +/- 2 and Prusament 63 +/- 1 at yield; Stratasys 62.3-64.6 at yield printed XZ, ASTM D638 (its PC White table duplicates the Antero 840CN03 figures and was not used)[1][23][5][4][24][6] | 55 (printed XY, ISO 527, 3DXTech) and 55 (printed on side long edge, ASTM D638, Stratasys PPSF); 79 at yield on extruded stock[3][7][21] |
| Young's modulusMPa | 2110 (Bambu Lab) to 2497 (PolyLite) printed XY, ISO 527; Prusament 1900, 3DXTech 2180[5][1][4][24] | 2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[3][7][21] |
| Elongation at break% | 3.8 (Bambu Lab) to 4.8 (PolyLite) at break, printed XY, ISO 527; 3DXTech quotes 14 at break, Prusament 5.8 at yield[5][1][24][4] | 3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[3][7][21] |
| Flexural strengthMPa | 81.3 (PolyMax) to 108 (Bambu Lab) printed XY, ISO 178; Prusament 88 ± 1, PolyLite 106.1[23][5][4][1] | 110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[3][7][21] |
| Flexural modulusMPa | 2050 (PolyMax) to 2640 (PolyLite) printed XY, ISO 178; Prusament 2100[23][1][4] | 2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[3][7] |

Stratasys PC Black gives 85.3 MPa flexural strength at break in ZX against no break in XZ (ASTM D790, printed)[4][23][6] | Izod notched 58.7 J/m and unnotched 165.5 J/m (printed, ASTM D256 Method A, Stratasys PPSF); 160 J/m notched on extruded stock[7][21] |
| Layer adhesion / Z tensileMPa | 37.1-45.3 at yield printed ZX (Stratasys PC Black and Red, ASTM D638); 41.4 (PolyMax) to 56 (Bambu Lab) printed Z; Prusa's interlayer adhesion test gives 21 +/- 2[4][23][5][6] | Not documented |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[2][4] | Brittle — snaps with little warning[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Shore D 79 (Prusa Polymers method) and Shore D 79 on extruded PC stock (ASTM D2240); Rockwell 70 (118) — the source does not name the scales[4][25] | Rockwell M86 on printed PPSF (ASTM D785, Stratasys); M96 on extruded PPSU stock (and an unlabelled 123)[7][21] |
| Creep resistance / sustained load1–5 | Excellent — holds load for years. Room-temperature tensile creep of moulded PC was still running unbroken at 41 MPa when the experiment was stopped for time; specimens failed within the test window only at 47-52 MPa (ASTM D638)[26] | Good. Printed PPSF holds 189 °C heat deflection at 1.8 MPa (ASTM D648) and extruded stock is rated 149 °C long-term service, but Ensinger does not claim the creep resistance it claims for PSU and PPS[7][21] |
| Fatigue / repeated-flex resistance1–5 | Good[4][2] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Z strength as % of XY% | 59-73 (Stratasys PC Black and Red, ZX against XZ tensile yield, ASTM D638); 76 for PolyLite PC and 90 for Bambu Lab (printed Z against XY tensile)[5][1][6] | Not documented |

| Glass transition (Tg)°C | 113 (Polymaker, DSC), 142.5 (Stratasys, ASTM D7426 inflection point) and 145 (Bambu Lab, DSC); Polymaker's material guide quotes 150[1][5][2][6] | 230 (DSC) — the highest glass transition in the dataset[3] |
| Melting point / Vicat°C | Amorphous — no melting point; Vicat 117–120 (Polymaker, ISO 306); decomposition above 360 °C[1][23] | Not documented |
| Continuous service temperature°C | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend; extruded PC stock is rated 121 long term (converted from 250 °F)[4][25] | 149 long-term service on extruded PPSU stock, converted from 300 °F[21] |
| Annealing response | 90 °C for 2 h (Polymaker)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 51.6 in XY over -50 to 30 °C, falling to 35.8 over 30-75 °C and 11.5 over 75-130 °C; 49.2 in XZ over -50 to 120 °C (printed, ASTM E831). Extruded PC stock gives 68.4 (ASTM D696)[6][25] | 55.0 (printed PPSF, ASTM D696; source states 5.5e-5 mm/mm/°C) and 55.8 on extruded stock (ASTM D696, from 3.1e-5 in/in/°F)[7][21] |
| Flammability / UL 94 | Flammable; no UL 94 rating on standard PC, though V-0 grades exist[27][1] | UL 94 V-0 at 1.5 mm, rated on the base resin[3] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors — unstabilised PC yellows and embrittles under UV[2] | Not documented |
| Chemical resistance | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[2] | Withstands repeated steam autoclaving, the usual reason to choose PPSU over PSU; Stratasys also lists PPSF as passing 24 h stress-crack exposure to antifreeze, petrol, motor oil, power-steering, transmission and washer fluid at 23 °C and 100 °C[3][7] |
| Water / humidity resistance in service1–5 | Good — minor absorption[5] | Not documented |

| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — an electrical insulator, which Polymaker lists as a headline advantage[24][2] | Volume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[7] |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[28] | 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[28] |
| 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[28] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[28][14] | Ventilated room or enclosure recommended[28] |
| Post-Processing | ||
| Sanding & machining | Sands and machines well; the toughness means it cuts rather than chips[20] | Not documented |
| Painting & finishing | Optical clarity survives printing, so transparent parts are usually left unpainted[2] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[20] | Not documented |
| Vapour / chemical smoothing | No practical vapour smoothing[20] | Not documented |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[20] | Not documented |
| Dimensional accuracy & detail | Warping is the dominant accuracy limit; light transmission 89 % on PolyLite PC (GB/T 2410)[1][2] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[29] | Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[30] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[29] | MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[30] |
| Solvent welding & smoothing agent | Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[31] | Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[30] |
