| Identity & Market | ||
| Base polymer / chemistry | Polycarbonate reinforced with chopped carbon fibre[1][2] | PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[3][4] |
| Densityg/cm³ | 1.22 (Prusament) and 1.36 (3DXTech), ISO 1183[1][2] | 1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[4][3] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 35–117; the middle of the market is about 63[5][6][7][8][9] | Mainstream 1 kg spools cluster near 21[10][11][12] |
| Price range across brandsUSD/kg | 35–117 across brands; Ambrosia 35, IEMAI 39, YXPOLYER 55, Spectrum PC CF 70, Prusament 94, 3DXTech 117[5][6][7][8][9] | 11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[13][11][14] |
| Market availability1–5 | Available from several mainstream brands[5][7][15] | Stocked by most mainstream brands[13][12][10] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.75, 0.8 and 1 kg spools[5][7] | 1.75 mm; 1 kg spools plus spool-less refills[10][16] |
| Typical applications | Stiff high-temperature structural parts — jigs, drone frames and under-bonnet brackets[1][2] | Display models and visible parts where a matte, non-reflective finish matters[4] |
| Diameter tolerance± mm | ±0.04 (Prusament PC Blend Carbon Fiber)[1] | ±0.03 (Bambu Lab)[17] |
| Printing Parameters | ||
| Nozzle temperature°C | 285 ± 10 (Prusament)[1] | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[4][3] |
| Bed temperature°C | 110 ± 10 (Prusament)[1] | 35–45 (Bambu Lab); 60 (Fiberlogy)[4][3] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive)[1][18] | Open frame is fine[4][3] |
| Part cooling fan | Off — Prusa allows 0–20 % and warns cooling significantly reduces interlayer adhesion[1] | Fan on; Fiberlogy specifies 75–100 %[4][3] |
| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[19] | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[4][3] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; the fibre reduces warping against unfilled PC[1][18] | None[4] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[19][20] | Sticks to anything[21] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[20] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[18][1] | Beginner — prints on any machine out of the box[4][3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[18] | Brass fine indefinitely[22][4][3] |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[18] | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[3][4][23] |
| 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[24][19][25] | Very low[22] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[19] | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[26] |
| Hotend requirement | All-metal hot end required (Simplify3D)[19] | No special hot-end required[21] |
| 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[27][28][24] | Moderate — 0.40 % saturated at 25 °C / 55 % RH[4] |
| Equilibrium moisture content at ~50 % RH% | 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[1] | 0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[4] |
| Drying temperature & time | Not documented | 50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[4][3][29] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[30] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[30] |
| 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[20][30] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[30] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[20] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[23][21] |
| 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] | 30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[4][31] |
| Young's modulusMPa | 2600 printed horizontal and 3200 printed vertical, ISO 527-1 (Prusament); 3DXTech quotes 6980[1][2] | 1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[4][3] |
| Elongation at break% | 4.6 at yield printed horizontal (Prusament); 3DXTech quotes 2.1 at break[1][2] | 14.8 (printed XY, ISO 527)[4] |
| Flexural strengthMPa | 94 ± 3 printed horizontal and 130 ± 2 printed vertical, ISO 178 (Prusament); 3DXTech quotes 85[1][2] | 53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[4][23] |
| Flexural modulusMPa | 3500 printed horizontal and 4200 printed vertical, ISO 178 (Prusament); 3DXTech quotes 6540[1][2] | 2360 (printed XY, ISO 178)[4] |
| Charpy impact, notchedkJ/m² | 12 ± 1 printed horizontal and 17 ± 2 printed vertical, ISO 179-1 notched (Prusament)[1] | 6.3 (printed XY, ISO 179, notched); unnotched 19.2[4] |
| Other impact data | Charpy unnotched 32 ± 5 printed horizontal and 35 ± 4 printed vertical (Prusament, ISO 179-1)[1] | Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[31] |
| Layer adhesion / Z tensileMPa | 23 ± 2 (Prusa Polymers interlayer adhesion test) — above the 21 ± 2 of unfilled Prusament PC Blend[1][28] | 22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[4][31] |
| Brittleness1–5 | Moderate[1][2] | Brittle — snaps with little warning[4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 83 Shore D (Prusa Polymers method), against 79 for unfilled Prusament PC Blend[1][28] | Not documented |
| 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[32][1] | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[31] |
| 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[32] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[33][26] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[4] |
| Z strength as % of XY% | Not documented | 73 by tensile, 55 by flexural (printed, Bambu Lab)[4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 114 (ISO 75, 0.45 MPa, Prusament)[1] | 58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[4][3] |
| HDT at 1.8 MPa°C | 106 (ISO 75, 1.8 MPa, Prusament), against 93 for unfilled Prusament PC Blend[1][28] | 52 (ISO 75, 1.8 MPa)[4] |
| Glass transition (Tg)°C | 127 (3DXTech, DSC)[2] | 61 (DSC)[4] |
| Melting point / Vicat°C | Not documented | 163 peak melt (DSC); Vicat 63 °C[4] |
| Continuous service temperature°C | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[28] | 54 — loaded bars begin to move at this temperature[31] |
| Annealing response | Not documented | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[4] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published by the major brands[23][34] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors unless stabilised[20] | Degrades within weeks outdoors[26][35] |
| Chemical resistance | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[20] | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[34][26] |
| Water / humidity resistance in service1–5 | Not documented | Good — insoluble in water[23] |
| Food contact | Bisphenol-A polycarbonate is not offered as food-contact filament[20] | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[26] |
| Biodegradability / compostability | Not biodegradable[20] | Industrially compostable only — needs sustained 55 °C; not home compostable[36][26] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[20] | Mechanically recyclable; not accepted in household plastic collection[36] |
| 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[37] | Low hazard — minimal VOC and particle emission[37] |
| 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[37] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[37][18] | None needed in a normal room[37] |
| 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[19] | Wet sanding — dry sanding heats the surface by friction and smears it[35][26] |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[19] | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[26][38] |
| Vapour / chemical smoothing | No practical vapour smoothing[19] | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[26] |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[19] | Support for PLA (Bambu Lab)[4] |
| Dimensional accuracy & detail | Not documented | Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4] |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[39] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[40] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[39] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[40][41] |
| Solvent welding & smoothing agent | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[42] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[43][41] |
