Identity & Market
Base polymer / chemistryPolycarbonate compounded with a conductive filler for static-dissipative parts[1]PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[2][3]
Densityg/cm³1.24 (ISO 1183, 3DXTech); Stratasys specific gravity 1.195 (ASTM D792)[1][4]1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[3][2]
Typical priceUSD/kg1 kg-equivalent spools cluster near 180[5]Mainstream 1 kg spools cluster near 21[6][7][8]
Price range across brandsUSD/kg180 at 3DXTech's 750 g pricing — the most expensive material in this group[5]11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[9][7][10]
Market availability1–5Special order, 1–2 makers worldwide[5]Stocked by most mainstream brands[9][8][6]
Spool sizes & diameters1.75 and 2.85 mm; 750 g spools plus Stratasys-compatible cartridges[5]1.75 mm; 1 kg spools plus spool-less refills[6][11]
Typical applicationsElectronics fixtures and trays that need PC heat resistance and static dissipation together[1]Display models and visible parts where a matte, non-reflective finish matters[3]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[12]
Printing Parameters
Nozzle temperature°CNot documented190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[3][2]
Bed temperature°CNot documented35–45 (Bambu Lab); 60 (Fiberlogy)[3][2]
Enclosure / chamber requirement1–5Enclosure required (passive)[13][14]Open frame is fine[3][2]
Part cooling fanNot documentedFan on; Fiberlogy specifies 75–100 %[3][2]
Bed surface & adhesion aidPEI with a glue stick or a commercial adhesive[15]Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[3][2]
Warping tendency1–5Severe — heated chamber needed[13][14]None[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15][16]Sticks to anything[17]
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[16]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[13]Beginner — prints on any machine out of the box[3][2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely[18][3][2]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[2][3][19]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry[20]Very low[18]
Heat-creep / jam sensitivity1–5Slightly sensitive[15]Moderate — good heatbreak cooling needed; PLA softens below 60 °C[21]
Hotend requirementAll-metal hot end required (Simplify3D)[15]No special hot-end required[17]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[22][23][20]Moderate — 0.40 % saturated at 25 °C / 55 % RH[3]
Equilibrium moisture content at ~50 % RH%Not documented0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[3]
Drying temperature & timeNot documented50 °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[3][2][24]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[25]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[25]
Effect of moisture on strengthNo 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][25]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[25]
Storage requirementAirtight containers with desiccant to prevent reabsorption[16]Sealed with desiccant below 20 % RH; shelf life at ambient is long[19][17]
Mechanical Properties
Tensile strength (XY)MPa68 at break (printed XY, ISO 527, 3DXTech) — above the 58 of 3DXTech's unfilled ezPC; Stratasys prints 47.6-49.4 at yield in XZ (ASTM D638)[1][26][4]30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[3][27]
Young's modulusMPa2300 (printed XY, ISO 527); Stratasys prints 1960 in XZ and 1810-1910 in ZX (ASTM D638)[1][4]1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[3][2]
Elongation at break%6 at break (printed XY, ISO 527), against 14 for the unfilled grade[1][26]14.8 (printed XY, ISO 527)[3]
Flexural strengthMPa95 (printed XY, ISO 178); Stratasys prints 82.6-83.2 at break in XZ against 46.3-49.5 in ZX (ASTM D790)[1][4]53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[3][19]
Flexural modulusMPa2310 (printed XY, ISO 178)[1]2360 (printed XY, ISO 178)[3]
Charpy impact, notchedkJ/m²Not documented6.3 (printed XY, ISO 179, notched); unnotched 19.2[3]
Other impact dataNot documentedIzod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[27]
Layer adhesion / Z tensileMPa32.5-37.9 at yield printed ZX (Stratasys, ASTM D638 on the Fortus 450mc and F900)[4]22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[3][27]
Brittleness1–5Moderate[1]Brittle — snaps with little warning[3]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell 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 an ESD grade[28]Not documented
Creep resistance / sustained load1–5Excellent — holds load for years. Moulded unfilled PC was still running unbroken under 41 MPa tensile creep at room temperature when the test was stopped, and the conductive filler leaves the glass transition unchanged at 142 °C, so the creep mechanism is polycarbonate's[29][4]Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[27]
Fatigue / repeated-flex resistance1–5Not documentedPoor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[30][21]
Elasticity / flexibility1–5Rigid[1]Rigid[3]
Z strength as % of XY%68-77 (Stratasys ZX against XZ tensile yield, ASTM D638)[4]73 by tensile, 55 by flexural (printed, Bambu Lab)[3]
Thermal Properties
HDT at 0.45 MPa°C143-146 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 66 psi); 135 moulded[4]58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[3][2]
HDT at 1.8 MPa°C140-144 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 264 psi); 124 moulded[4]52 (ISO 75, 1.8 MPa)[3]
Glass transition (Tg)°C143 (DSC, 3DXTech) and 142 (Stratasys, ASTM D7426)[1][4]61 (DSC)[3]
Melting point / Vicat°CNot documented163 peak melt (DSC); Vicat 63 °C[3]
Continuous service temperature°C113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[23]54 — loaded bars begin to move at this temperature[27]
Annealing responseNot documented50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[3]
Thermal expansion (CTE)µm/m·K68.4 on extruded unfilled PC stock (ASTM D696; source states 3.8e-5 in/in/°F); no figure is published for a conductive-filled grade[28]Not documented
Flammability / UL 94Not documentedFlammable; no UL 94 rating published by the major brands[19][31]
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[21][32]
Chemical resistanceWithstands oils, solvents and fuels; Polymaker rates it good against weak acids[16]Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[31][21]
Water / humidity resistance in service1–5Not documentedGood — insoluble in water[19]
Food contactBisphenol-A polycarbonate is not offered as food-contact filament[16]Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[21]
Biodegradability / compostabilityNot biodegradable[16]Industrially compostable only — needs sustained 55 °C; not home compostable[33][21]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[16]Mechanically recyclable; not accepted in household plastic collection[33]
Electrical & ESD propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ezPC[1][26]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[34]Low hazard — minimal VOC and particle emission[34]
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[34]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[34][13]None needed in a normal room[34]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands and machines well; the toughness means it cuts rather than chips[15]Wet sanding — dry sanding heats the surface by friction and smears it[32][21]
Gluing & solvent weldingCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[15]Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[21][35]
Vapour / chemical smoothingNo practical vapour smoothing[15]No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[21]
Support material pairingPrints its own supports; 3DXTech sells a dedicated PC break-away support[15]Support for PLA (Bambu Lab)[3]
Dimensional accuracy & detailNot documentedMatte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[3]
Solvents & Solubility
Soluble inDichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[36]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[37]
Softened or crazed byMethanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[36]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[37][38]
Solvent welding & smoothing agentDichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[39]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[40][38]
