Printing Parameters
Nozzle temperature°CNot documented245 ± 10 (Prusament) — 25 °C below the carbon-fibre grade[2][8]
Bed temperature°CNot documented95 ± 10 (Prusament)[2]
Enclosure / chamber requirement1–5Enclosure required (passive)[9]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[10][11]
Part cooling fanNot documentedOff — Prusa runs 0 % except 100 % on bridges[2]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[12][9]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][13]
Warping tendency1–5Not documentedHigh — enclosure needed for reliable large parts; Prusa recommends a brim[2]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[12]Very difficult — special plates or slurry required[2]
Stringing / oozing tendency1–5Moderate — retraction tuning needed[9]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[9][14]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[2]
Extruder requirementNot documentedPrusa states a hardened nozzle is necessary and recommends a brim[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]Hardened steel required[2]
Abrasiveness1–5Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[1]Highly abrasive — standard GF composite[2]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[14]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[15]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[12]Not documented
Hotend requirementMay require an all-metal hot end (Simplify3D)[12]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — the PA612 matrix sits between PA6 and PA12[16][17]Low (0.1–0.3 %) — 0.11 % at both 24 h and 7 days, higher than the carbon-fibre grade's 0.04 % but still very low[2][8]
Equilibrium moisture content at ~50 % RH%Not documented0.11 after 24 h and 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[2]
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][17]Not applicable in practice at 0.11 % equilibrium uptake[2]
Storage requirementSealed below 20 % RH with desiccant[14]No special storage needed[2]
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[18][19]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]46.6 ± 1.3 filament tensile yield (Prusament, ISO 527) — more than double the carbon-fibre grade's 21[2][8]
Young's modulusMPa4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[1]Not documented
Elongation at break%3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[1]Not documented
Charpy impact, notchedkJ/m²5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[1]7.9 ± 0.4 printed horizontal and 9.9 ± 0.8 printed vertical XZ (ISO 179-1, notched)[2]
Other impact dataCharpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[1]Not documented
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]Not documented
Brittleness1–5Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[1]Moderate[2]
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[20]Rockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a glass-fibre PP filament[21]
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[22][1]Not documented
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[22]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Z strength as % of XY%26 (printed Z against XY tensile)[1]Not documented
Thermal Properties
HDT at 0.45 MPa°C157.0 (ISO 75, 0.45 MPa)[1]138.3 (ISO 75, 0.45 MPa)[2]
HDT at 1.8 MPa°C125.4 (ISO 75, 1.8 MPa)[1]112.6 (ISO 75, 1.8 MPa)[2]
Glass transition (Tg)°C41.8 (DSC)[1]Not documented
Melting point / Vicat°C187.3 melting (DSC); Vicat 190.0 (ISO 306)[1]Not documented
Flammability / UL 94Flammable; no UL 94 rating published for the grades surveyed[18]Not documented
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — unstabilised polyamide yellows under UV[9]Not documented
Chemical resistanceWithstands oils, fuels and alkalis[9]Excellent against acids, alkalis and most solvents[11]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[2]
Food contactNot food-contact certified as filament[9]Not documented
Biodegradability / compostabilityNot biodegradable[9]Not documented
RecyclabilityNot accepted in household plastic collection[9]Not documented
Electrical & ESD propertiesStatic-dissipative — the reason the grade exists; Polymaker's insulating nylon composites sit above 10¹² ohm by contrast[1][16]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[23]Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[23]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[23]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[23]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[23]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[23]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[23]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[18]Glass fibre is bound in the matrix; avoid inhaling sanding dust[2]
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[12]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[12]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[12]Not documented
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[24]None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[25][26]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[24]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[25]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[24]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[25]
