Identity & Market
Base polymer / chemistryCarbon-filled polyamide compounded to a static-dissipative resistivity — Polymaker's grade uses a PA612 matrix[1]PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[2][3]
Densityg/cm³1.10 (ISO 1183)[1]1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[3][2]

Enclosure / chamber requirement1–5Enclosure required (passive)[12]Open frame is fine[3][2]
Part cooling fanNot documentedFan on; Fiberlogy specifies 75–100 %[3][2]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[13][12]Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[3][2]
Warping tendency1–5Not documentedNone[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[13]Sticks to anything[14]
Stringing / oozing tendency1–5Moderate — retraction tuning needed[12]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[12][15]Beginner — prints on any machine out of the box[3][2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-ESD and recommends hardened steel or ruby[1]Brass fine indefinitely[16][3][2]
Abrasiveness1–5Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[1]Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[2][3][17]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[15]Very low[16]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[13]Moderate — good heatbreak cooling needed; PLA softens below 60 °C[18]
Hotend requirementMay require an all-metal hot end (Simplify3D)[13]No special hot-end required[14]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — the PA612 matrix sits between PA6 and PA12[19][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][21]
Symptoms when wetNot documentedBubbling and popping at the nozzle, stringing, rough surface and weak layers[15]
Effect of moisture on strengthPolymaker publishes dry and wet printed blocks for PA612-ESD itself: at 4.64 % moisture tensile falls 84.3 → 73.6 MPa and modulus 4294 → 3731 MPa[1][20]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[15]
Storage requirementSealed below 20 % RH with desiccant[15]Sealed with desiccant below 20 % RH; shelf life at ambient is long[17][14]
Hydrolysis at melt temperaturePolymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[22][23]Not documented
Mechanical Properties
Tensile strength (XY)MPa84.3 ± 2.3 printed XY dry (annealed 100 °C/16 h), 73.6 ± 2.3 conditioned to 4.64 % moisture, ISO 527[1]30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[3][24]
Young's modulusMPa4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[1]1960 (Bambu Lab, printed XY, ISO 527); Fiberlogy PLA Mineral quotes 3500 (ISO 527, specimen type not stated)[3][2]
Elongation at break%3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[1]14.8 (printed XY, ISO 527)[3]
Flexural strengthMPaNot documented53 (printed XY, ISO 178) — 30 % below PLA Basic at 76[3][17]
Flexural modulusMPaNot documented2360 (printed XY, ISO 178)[3]
Charpy impact, notchedkJ/m²5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[1]6.3 (printed XY, ISO 179, notched); unnotched 19.2[3]
Other impact dataCharpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[1]Izod 6.1 kJ/m² on My Tech Fun printed bars for PolyTerra PLA[24]
Layer adhesion / Z tensileMPa21.5 ± 2.7 printed Z dry — only a quarter of XY, the most anisotropic nylon composite here; 19.2 ± 1.6 conditioned[1]22 (printed Z, ISO 527); flexural Z falls to 29 against 53 in XY; 12.9 on My Tech Fun layer-adhesion bars[3][24]
Brittleness1–5Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[1]Brittle — snaps with little warning[3]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a conductive carbon-filled nylon filament[25]Not documented
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load at 110 °C continuous service; the PA612 matrix here still takes up 4.64 % moisture at conditioning, which softens it[26][1]Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[24]
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[26]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[27][18]
Elasticity / flexibility1–5Rigid[1]Rigid[3]
Z strength as % of XY%26 (printed Z against XY tensile)[1]73 by tensile, 55 by flexural (printed, Bambu Lab)[3]
Thermal Properties
HDT at 0.45 MPa°C157.0 (ISO 75, 0.45 MPa)[1]58 (Bambu Lab) and 48 (Fiberlogy PLA Mineral), ISO 75 at 0.45 MPa[3][2]
HDT at 1.8 MPa°C125.4 (ISO 75, 1.8 MPa)[1]52 (ISO 75, 1.8 MPa)[3]
Glass transition (Tg)°C41.8 (DSC)[1]61 (DSC)[3]
Melting point / Vicat°C187.3 melting (DSC); Vicat 190.0 (ISO 306)[1]163 peak melt (DSC); Vicat 63 °C[3]
Continuous service temperature°CNot documented54 — loaded bars begin to move at this temperature[24]
Annealing responseNot documented50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[3]
Flammability / UL 94Flammable; no UL 94 rating published for the grades surveyed[22]Flammable; no UL 94 rating published by the major brands[17][28]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — unstabilised polyamide yellows under UV[12]Degrades within weeks outdoors[18][29]
Chemical resistanceWithstands oils, fuels and alkalis[12]Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[28][18]
Water / humidity resistance in service1–5Not documentedGood — insoluble in water[17]
Food contactNot food-contact certified as filament[12]Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[18]
Biodegradability / compostabilityNot biodegradable[12]Industrially compostable only — needs sustained 55 °C; not home compostable[30][18]
RecyclabilityNot accepted in household plastic collection[12]Mechanically recyclable; not accepted in household plastic collection[30]
Electrical & ESD propertiesStatic-dissipative — the reason the grade exists; Polymaker's insulating nylon composites sit above 10¹² ohm by contrast[1][19]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[31]Low hazard — minimal VOC and particle emission[31]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[31]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[31]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[31]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[31]None needed in a normal room[31]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[22]Not documented
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[13]Wet sanding — dry sanding heats the surface by friction and smears it[29][18]
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[13]Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[18][32]
Vapour / chemical smoothingNo practical vapour smoothing[13]No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[18]
Support material pairingNot documentedSupport 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 inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[33]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[34]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[33]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[34][35]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[33]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[36][35]
