| Market availability1–5 | Available from several mainstream brands[6][8][19] | Ubiquitous, every brand and retailer[11][8][6][15][12][13] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.75, 0.8 and 1 kg spools[6][8] | 1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[11][8] |
| Typical applications | Stiff high-temperature structural parts — jigs, drone frames and under-bonnet brackets[1][2] | Gaskets, phone cases, tyres, vibration mounts and protective covers[20] |
| Diameter tolerance± mm | ±0.04 (Prusament PC Blend Carbon Fiber)[1] | ±0.06 (Prusament) — the loosest tolerance Prusa publishes, because soft filament deforms in the gauge[4] |
| Printing Parameters | ||
| Nozzle temperature°C | 285 ± 10 (Prusament)[1] | 210–240; Polymaker 210–230, Prusament 230 ± 10, Bambu Lab HF 220–240[3][4][5] |
| Bed temperature°C | 110 ± 10 (Prusament)[1] | 25–65; Prusament 65 ± 10, Bambu Lab 30–35, Polymaker 25–60[4][5][3] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[1][21] | Open frame is fine[3] |
| Part cooling fan | Off — Prusa allows 0–20 % and warns cooling significantly reduces interlayer adhesion[1] | Fan on[3][5] |
| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[22] | PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[23][20] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 2.4 at Polymaker's 30–50 mm/s and 2.4 at Prusa's 30 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer; Bambu Lab's high-flow grade lifts the cap to 200 mm/s (16 mm³/s)[3][4][5] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; the fibre reduces warping against unfilled PC[1][21] | None[3] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[22][24] | Sticks to most surfaces[3] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[24] | Moderate — retraction tuning needed; Polymaker specifies 3–6 mm retraction, well above the 1–3 mm used for rigid filaments[3] |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[21][1] | Intermediate — dry filament and a tuned profile; the speed ceiling is the main constraint[3][4] |
| Extruder requirement | Not documented | Direct drive strongly preferred. BASF rates its 95A grade as running on both direct-drive and Bowden machines, but every maker caps speed at 15–50 mm/s unless the grade is specifically high-flow[25][3][4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[21] | Brass fine indefinitely[26] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[21] | Non-abrasive[26] |
| Nozzle clog risk1–5 | 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[27][22][28] | Moderate — needs dry filament and a clean nozzle[29] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[22] | High — all-metal hotend and strong cooling needed; soft filament buckles in the cold zone if it slows[20] |
| Hotend requirement | All-metal hot end required (Simplify3D)[22] | No special hot-end required, but a direct-drive extruder is (Simplify3D)[23] |
| 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[30][31][27] | Low (0.1–0.3 %) by Prusa's measurement at 0.04 % in 7 days, but Polymaker measures 0.82 % equilibrium and groups TPU with the highly hygroscopic materials[4][3][29] |
| Equilibrium moisture content at ~50 % RH% | 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[1] | 0.82 equilibrium (Polymaker); 0.02 after 24 h and 0.04 after 7 days at 22 % RH (Prusa)[3][4] |
| Drying temperature & time | Not documented | 70 °C for 8 h (Polymaker); 70 °C for 8 h or an 80–90 °C heatbed for 12 h (Bambu Lab)[3][5] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[29] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[29] |
| 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[24][29] | Polymaker groups TPU with nylon, PVA and PETG as highly hygroscopic and says these often need to stay in a dryer while printing; no dry-versus-conditioned figures are published[29] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[24] | Sealed with desiccant; often kept in a dryer during the print[29] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 64 ± 3 printed horizontal and 70 ± 3 printed vertical at yield, ISO 527-1 (Prusament); 3DXTech quotes 73 at break[1][2] | 41.4 ± 1.3 printed (Prusament, ISO 37); NinjaTek Cheetah 39 ultimate (ASTM D638)[4][32] |
| Young's modulusMPa | 2600 printed horizontal and 3200 printed vertical, ISO 527-1 (Prusament); 3DXTech quotes 6980[1][2] | Not documented |
| Elongation at break% | 4.6 at yield printed horizontal (Prusament); 3DXTech quotes 2.1 at break[1][2] | 551 ± 24 printed (Polymaker, ISO 37); the filament itself stretches 7264 % before break (Prusa, ISO 527)[3][4] |
| Flexural strengthMPa | 94 ± 3 printed horizontal and 130 ± 2 printed vertical, ISO 178 (Prusament); 3DXTech quotes 85[1][2] | Not documented |
| Flexural modulusMPa | 3500 printed horizontal and 4200 printed vertical, ISO 178 (Prusament); 3DXTech quotes 6540[1][2] | Not documented |
| Charpy impact, notchedkJ/m² | 12 ± 1 printed horizontal and 17 ± 2 printed vertical, ISO 179-1 notched (Prusament)[1] | Not documented |
| Other impact data | Charpy unnotched 32 ± 5 printed horizontal and 35 ± 4 printed vertical (Prusament, ISO 179-1)[1] | Not documented |
| Layer adhesion / Z tensileMPa | 23 ± 2 (Prusa Polymers interlayer adhesion test) — above the 21 ± 2 of unfilled Prusament PC Blend[1][31] | 9.5 ± 0.2 (Prusament interlayer adhesion, ISO 527)[4] |
| Brittleness1–5 | Moderate[1][2] | Very ductile — bends far before failing[3][4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 83 Shore D (Prusa Polymers method), against 79 for unfilled Prusament PC Blend[1][31] | 92 ± 0.4 Shore A and 39 ± 0.7 Shore D (Prusament); 95A (Polymaker, ISO 7619-1); 91 Shore A / 40 Shore D (Fiberlogy FiberFlex 40D, ISO 7619); 95A (NinjaTek Cheetah, ASTM D2240); 94.5 A measured on a printed Bambu Lab 95A part and 96.2 A on a Qidi one (My Tech Fun)[4][3][33][32][34] |
| Creep resistance / sustained load1–5 | 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[35][1] | Poor — deforms under load at room temperature; a loaded bar crept from 74.5 to 82.7 mm over 5 days[34] |
| Fatigue / repeated-flex resistance1–5 | Good. No fatigue test data was found for a carbon-fibre PC filament; the unfilled polymer is rated Good on the same scale[35] | Excellent — living hinges viable[20] |
| Elasticity / flexibility1–5 | Rigid[1] | Rubbery / highly elastic[3][4] |
| Wear resistance & friction | Not documented | Abrasion resistance is a headline property; BASF measures 64 mm³ loss by ISO 4649 on its 92A grade[25] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 114 (ISO 75, 0.45 MPa, Prusament)[1] | Not documented |
| HDT at 1.8 MPa°C | 106 (ISO 75, 1.8 MPa, Prusament), against 93 for unfilled Prusament PC Blend[1][31] | Not documented |
| Glass transition (Tg)°C | 127 (3DXTech, DSC)[2] | Not documented |
| Melting point / Vicat°C | Not documented | 144 melting (BASF 95A, ISO 11357-3); Bambu Lab 183, Polymaker's modulus at 100 % elongation 8.9 MPa[25][5] |
| Continuous service temperature°C | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[31] | Bounded by a melting point of 144–183 °C; no loaded-bar service figure is published for TPU[25][5] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published for the grades surveyed[3] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors unless stabilised[24] | Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[20] |
| Chemical resistance | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[24] | Good resistance to oils and common solvents (BASF)[25] |
| Food contact | Bisphenol-A polycarbonate is not offered as food-contact filament[24] | Not food safe without specific certification (Polymaker)[20] |
| Biodegradability / compostability | Not biodegradable[24] | Not biodegradable[20] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[24] | Not accepted in household plastic collection[20] |
| Electrical & ESD properties | Surface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[2] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[36] | Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[36] |
| 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[36] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[36][21] | Open a window / occasional ventilation[36] |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[2] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands and machines well; the toughness means it cuts rather than chips[22] | Sanding is impractical — the surface tears rather than abrades[20] |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[22] | Cyanoacrylate bonds TPU; no common solvent welds it[20] |
| Vapour / chemical smoothing | No practical vapour smoothing[22] | No practical vapour smoothing[20] |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[22] | Polymaker warns TPU supports are often very difficult to remove; PolyDissolve S1 is rated for TPU[20] |
| Dimensional accuracy & detail | Not documented | Stringing and elephant-foot are the accuracy limits; retraction has to be long and slow[3] |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[37] | DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[38] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[37] | Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[38] |
| Solvent welding & smoothing agent | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[39] | None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[38] |
