| Typical applications | Break-away and d-limonene-soluble support for ABS and ASA, and a light model material in its own right[2] | Stiff high-temperature structural parts — jigs, drone frames and under-bonnet brackets[3][4] |
| Diameter tolerance± mm | Not documented | ±0.04 (Prusament PC Blend Carbon Fiber)[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 230–245 (Simplify3D)[13] | 285 ± 10 (Prusament)[3] |
| Bed temperature°C | 100–115 (Simplify3D)[13] | 110 ± 10 (Prusament)[3] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[14] | Enclosure required (passive)[3][14] |
| Part cooling fan | Part cooling fan not required[13] | Off — Prusa allows 0–20 % and warns cooling significantly reduces interlayer adhesion[3] |
| Bed surface & adhesion aid | Glue stick, glass plate, Kapton tape or PET sheets[13] | PEI with a glue stick or a commercial adhesive[15] |
| Warping tendency1–5 | Moderate — needs adhesion aid or draught shield[14] | High — enclosure needed for reliable large parts; the fibre reduces warping against unfilled PC[3][14] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[13] | Needs a specific surface plus adhesive[15][16] |
| Stringing / oozing tendency1–5 | Slight — HIPS oozes less than ABS[13][17] | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[16] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[14] | Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[14][3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[14] | Hardened steel required[14] |
| Abrasiveness1–5 | Non-abrasive[14] | Highly abrasive — standard CF composite[14] |
| Nozzle clog risk1–5 | Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[13][18][2] | High — jams from moisture, heat creep or particles; PC already absorbs water from the air and 3DXTech adds a hardened 0.4 mm minimum nozzle, 0.25 mm layers and a 120 °C pre-dry[19][15][20] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[13] | Slightly sensitive[15] |
| Hotend requirement | No special hot-end required[13] | All-metal hot end required (Simplify3D)[15] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[13] | Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[21][22][19] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[23] | Bubbling and popping at the nozzle, stringing and a rough surface[23] |
| 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[23] | 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[16][23] |
| Storage requirement | Sealed with desiccant; less critical than for the polyamides[23] | Airtight containers with desiccant to prevent reabsorption[16] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 40 at break (printed XY, ISO 527)[1] | 64 ± 3 printed horizontal and 70 ± 3 printed vertical at yield, ISO 527-1 (Prusament); 3DXTech quotes 73 at break[3][4] |
| Young's modulusMPa | 1350 (printed XY, ISO 527) — the lowest modulus of the styrenics here[1] | 2600 printed horizontal and 3200 printed vertical, ISO 527-1 (Prusament); 3DXTech quotes 6980[3][4] |
| Elongation at break% | 18 at break (printed XY, ISO 527)[1] | 4.6 at yield printed horizontal (Prusament); 3DXTech quotes 2.1 at break[3][4] |
| Flexural strengthMPa | 70 (printed XY, ISO 178)[1] | 94 ± 3 printed horizontal and 130 ± 2 printed vertical, ISO 178 (Prusament); 3DXTech quotes 85[3][4] |
| Flexural modulusMPa | 1600 (printed XY, ISO 178)[1] | 3500 printed horizontal and 4200 printed vertical, ISO 178 (Prusament); 3DXTech quotes 6540[3][4] |
| Charpy impact, notchedkJ/m² | Not documented | 12 ± 1 printed horizontal and 17 ± 2 printed vertical, ISO 179-1 notched (Prusament)[3] |
| Other impact data | Not documented | Charpy unnotched 32 ± 5 printed horizontal and 35 ± 4 printed vertical (Prusament, ISO 179-1)[3] |
| Layer adhesion / Z tensileMPa | Not documented | 23 ± 2 (Prusa Polymers interlayer adhesion test) — above the 21 ± 2 of unfilled Prusament PC Blend[3][22] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[1] | Moderate[3][4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 83 Shore D (Prusa Polymers method), against 79 for unfilled Prusament PC Blend[3][22] |
| Creep resistance / sustained load1–5 | Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[1][13] | Excellent — holds load for years. Room-temperature tensile creep of moulded unfilled PC ran unbroken at 41 MPa until the test was stopped; short carbon fibre raises the flexural modulus from about 2.1 to 3.5-6.5 GPa, which reduces creep strain further[24][3] |
| Fatigue / repeated-flex resistance1–5 | Moderate[1] | Good. No fatigue test data was found for a carbon-fibre PC filament; the unfilled polymer is rated Good on the same scale[24] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 114 (ISO 75, 0.45 MPa, Prusament)[3] |
| HDT at 1.8 MPa°C | Not documented | 106 (ISO 75, 1.8 MPa, Prusament), against 93 for unfilled Prusament PC Blend[3][22] |
| Glass transition (Tg)°C | 100 (DSC)[1] | 127 (3DXTech, DSC)[4] |
| Melting point / Vicat°C | Amorphous — no melting point[1] | Not documented |
| 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] |
| Flammability / UL 94 | Flammable; no UL 94 rating published[1] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement — polystyrene yellows and chalks under UV[25] | Degrades within weeks outdoors unless stabilised[16] |
| 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[16] |
| Food contact | Not food safe[25] | Bisphenol-A polycarbonate is not offered as food-contact filament[16] |
| Biodegradability / compostability | Not biodegradable[25] | Not biodegradable[16] |
| Recyclability | Not accepted in household plastic collection[25] | Mechanically recyclable but not accepted in household plastic collection[16] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[1] | Surface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[4] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[26] | Moderate — measurable VOCs and UFPs, ventilation advised[26] |
| VOC emission rateµg/min | 12–113 styrene, the range measured across ABS and the one HIPS filament tested[26] | 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[26] | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[26] |
| Hazardous species emitted | Styrene was the only dominant VOC identified for the HIPS filament tested[26] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[26] | Ventilated room or enclosure recommended[26][14] |
| Dust & fibre handling hazard | Not documented | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[4] |
| Post-Processing | ||
| Sanding & machining | Sands and paints readily, like ABS[25] | Sands and machines well; the toughness means it cuts rather than chips[15] |
| Gluing & solvent welding | Solvent-welds with d-limonene, and with acetone via its polystyrene backbone[13][2] | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[15] |
| Vapour / chemical smoothing | d-limonene attacks the surface; acetone smoothing is far less effective than on ABS[2][13] | No practical vapour smoothing[15] |
| 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[15] |
| Solvents & Solubility | ||
| Soluble in | d-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[27][28][29] | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[30] |
| 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.[31] | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[30] |
| Solvent welding & smoothing agent | Limonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[27][31] | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[32] |
