| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield[10] | Severe — heated chamber needed[3][10] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[9] | Needs a specific surface plus adhesive[12][13] |
| Stringing / oozing tendency1–5 | Slight — HIPS oozes less than ABS[9][14] | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[13] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[10] | Advanced — enclosure, hardware upgrades, tuning[4][10] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[10] | Brass fine indefinitely[10] |
| Abrasiveness1–5 | Non-abrasive[10] | Non-abrasive[3] |
| Nozzle clog risk1–5 | Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[9][15][2] | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 6 h pre-dry at 80 °C[16] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[9] | Slightly sensitive[12] |
| Hotend requirement | No special hot-end required[9] | All-metal hot end required (Simplify3D)[12] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[9] | Low (0.1–0.3 %) — 0.12 % saturated at 25 °C / 55 % RH (Bambu Lab), half that of unfilled Bambu Lab PC[4][17] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.12 saturated at 25 °C / 55 % RH (Bambu Lab)[4] |
| Drying temperature & time | Not documented | 75 °C for 6 h (Polymaker)[3] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[18] | Bubbling and popping at the nozzle, stringing and a rough surface[18] |
| Effect of moisture on strength | Polymaker 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[18] | 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[13][18] |
| Storage requirement | Sealed with desiccant; less critical than for the polyamides[18] | Airtight containers with desiccant to prevent reabsorption[13] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 40 at break (printed XY, ISO 527)[1] | 60 ± 4 (Bambu Lab) and 67 ± 4.5 (Polymaker) printed XY, ISO 527[4][3] |
| Young's modulusMPa | 1350 (printed XY, ISO 527) — the lowest modulus of the styrenics here[1] | 1670 ± 40 (Bambu Lab) and 2634 ± 182 (Polymaker) printed XY, ISO 527[4][3] |
| Elongation at break% | 18 at break (printed XY, ISO 527)[1] | 2.4 ± 0.3 (Bambu Lab) and 3.49 ± 0.7 (Polymaker) at break, printed XY, ISO 527 — the retardant roughly halves unfilled PC's elongation[4][3][19] |
| Flexural strengthMPa | 70 (printed XY, ISO 178)[1] | 96.6 ± 1.3 printed XY, ISO 178 (Polymaker)[3] |
| Flexural modulusMPa | 1600 (printed XY, ISO 178)[1] | 2518 ± 53 printed XY, ISO 178 (Polymaker)[3] |

| Other impact data | Not documented | Notched Charpy 7.5 ± 1.6 kJ/m² at −30 °C printed XY (Polymaker, ISO 179-1/1eA)[3] |
| Layer adhesion / Z tensileMPa | Not documented | 21 ± 3 (Bambu Lab) and 46 ± 4.8 (Polymaker) printed Z, ISO 527[4][3] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1] | Moderate[4][3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 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 a flame-retardant filament[20] |
| Creep resistance / sustained load1–5 | Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][9] | Good. Moulded unfilled PC sustained 41 MPa tensile creep at room temperature without breaking, but the retardant package drops the glass transition to 115 °C in Polymaker's grade, so the unfilled rating is not carried over in full[21][3] |
| Fatigue / repeated-flex resistance1–5 | Moderate[1] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Z strength as % of XY% | Not documented | 35 (Bambu Lab) to 69 (Polymaker), printed[4][3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 110 (Polymaker) and 113 (Bambu Lab), ISO 75 at 0.45 MPa[3][4] |
| HDT at 1.8 MPa°C | Not documented | 107 (Polymaker) and 108 (Bambu Lab), ISO 75 at 1.8 MPa[3][4] |
| Glass transition (Tg)°C | 100 (DSC)[1] | 115 (Polymaker) and 145 (Bambu Lab), DSC[3][4] |
| Melting point / Vicat°C | Amorphous — no melting point[1] | Amorphous — no melting point; Vicat 114 (Bambu Lab, ISO 306)[4] |
| Continuous service temperature°C | Bounded by a glass transition of 100 °C; no loaded-bar service figure is published for HIPS[1] | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[22] |
| Thermal expansion (CTE)µm/m·K | Not documented | 68.4 on extruded unfilled PC stock (ASTM D696; source states 3.8e-5 in/in/°F); no figure is published for a flame-retardant grade[20] |
| Flammability / UL 94 | Flammable; no UL 94 rating published[1] | UL 94 V-0 (Polymaker PolyMax PC-FR); 3DXTech rates its FR PC/ABS V-0 at 1.5 mm on the base resin[3][23] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — polystyrene yellows and chalks under UV[24] | Degrades within weeks outdoors unless stabilised[13] |
| Chemical resistance | Dissolves completely in d-limonene — the basis of its use as a soluble support[2] | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[13] |
| Food contact | Not food safe[24] | Bisphenol-A polycarbonate is not offered as food-contact filament[13] |
| Biodegradability / compostability | Not biodegradable[24] | Not biodegradable[13] |
| Recyclability | Not accepted in household plastic collection[24] | Mechanically recyclable but not accepted in household plastic collection[13] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[25] | Moderate — measurable VOCs and UFPs, ventilation advised[25] |
| VOC emission rateµg/min | 12–113 styrene, the range measured across ABS and the one HIPS filament tested[25] | Not documented |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10⁹ median for the HIPS filament tested, an order of magnitude below ABS but forty times PLA[25] | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[25] |
| Hazardous species emitted | Styrene was the only dominant VOC identified for the HIPS filament tested[25] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[25] | Ventilated room or enclosure recommended[25][10] |
| Post-Processing | ||
| Sanding & machining | Sands and paints readily, like ABS[24] | Sands and machines well; the toughness means it cuts rather than chips[12] |
| Gluing & solvent welding | Solvent-welds with d-limonene, and with acetone via its polystyrene backbone[9][2] | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[12] |
| Vapour / chemical smoothing | d-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][9] | No practical vapour smoothing[12] |
| Support material pairing | Used as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[2] | Prints its own supports; 3DXTech sells a dedicated PC break-away support[12] |
| Solvents & Solubility | ||
| Soluble in | d-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[26][27][28] | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[29] |
| Softened or crazed by | Limonene also disrupts layer adhesion in some ABS and ASA grades, so an ABS model can flake apart in the same bath.[30] | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[29] |
| Solvent welding & smoothing agent | Limonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[26][30] | Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[31] |
