Market snapshot
Listing priceUSD/kg; dated snapshotsNot documented$281.22/kg median; $195.00–$698.00/kg across 6 dated product listings
Identity & Market
Base polymer / chemistryAramid-fibre reinforced polyamide[1]Polyetherimide, ULTEM 1010 grade — the higher-temperature, food- and medical-contact PEI[2][3]
Densityg/cm³Not documented1.27 (ISO 1183, 3DXTech and Prusament); 1.29 specific gravity on moulded plaques (ASTM D792, Stratasys)[2][3][4]
Typical priceUSD/kgNot documented1 kg-equivalent spools span 195–698; the middle of the market is about 270[5][6][7][8][9]
Price range across brandsUSD/kgNot documented195-698 across brands and grades; 3DXTech ThermaX PEI 1010 195 at 2 kg, IEMAI 3D 223 at 1 kg, 3D4Makers 270 at 2 kg, Prusament 292 at 500 g, Kimya 347 at 500 g, 3DXTech ESD-PEI 1010 698 at 500 g[5][6][7][8][9]
Market availability1–5Special order, 1–2 makers worldwide — no aramid-filled nylon filament was found in any catalogue searched; the aramid filaments that do exist in the retail market use an ASA matrix[10][5]Niche, a handful of specialist brands[5][6][7][8]
Spool sizes & diametersNot documented1.75 and 2.85 mm; 200 g to 2 kg spools, plus Stratasys canisters[5][8][4]
Typical applicationsNot documentedAutoclavable tooling, food-contact fixtures and parts that must hold load near 200 °C[3]
Printing Parameters
Nozzle temperature°CNot documented410 ± 10 (Prusament) — the hottest nozzle in the dataset[3]
Bed temperature°CNot documented140–160 (Prusament); 130–140 (3DXTech)[3][2]
Enclosure / chamber requirement1–5Enclosure required (passive) — as for every nylon[1]Actively heated chamber required — Prusa specifies 90 °C[3]
Recommended chamber temperature°CNot documented90 (Prusament)[3]
Bed surface & adhesion aidNot documentedPA nylon sheet or powder-coated sheet with high-temperature glue (Prusament)[3]
Warping tendency1–5Not documentedSevere — heated chamber needed[3]
Overall printing difficulty1–5Not documentedExpert / industrial hardware only[3][11]
Extruder requirementNot documentedA hot end rated to 420 °C, a heated chamber and a high-temperature bed; Prusa dries the filament at 150 °C for 6–8 h before printing[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — no aramid-filled nylon datasheet was obtainable; Polymaker measures about 9 h of brass nozzle life on its fibre-filled nylons[12]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[3]
Abrasiveness1–5Highly abrasive — fibre-reinforced nylon composite[12]Non-abrasive when unfilled[2]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles; nylon already needs a drybox and Prusa names kevlar among the fibres that raise nozzle-clogging risk[13]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 150 °C pre-dry before every print[14]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Very high (>2 %) — the polyamide matrix governs uptake[15]Not documented
Equilibrium moisture content at ~50 % RH%Not documented0.4 in 24 h and 0.7 in 7 days at 24 °C and 22 % RH (Prusament)[3]
Drying temperature & timeNot documented150 °C for 6–8 h (Prusament) — the hottest drying schedule in the dataset[3]
Effect of moisture on strengthPolymaker's printed dry-versus-wet blocks for its CoPA nylon show what conditioning does to the family: tensile 78.0 → 34.3 MPa and modulus 2703 → 724 MPa, with notched Charpy rising 6.9 → 27.7 kJ/m². Fibre reinforcement reduces but does not remove the effect[16][17]No dry-versus-conditioned figures are published; 3DXTech mandates a 150 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[14]

Other impact dataNot documentedIzod notched 26.6-36.3 J/m XZ against 21.7-27.2 J/m ZX; unnotched 260-406 J/m XZ against 68-116 J/m ZX (printed, ASTM D256/D4812, Stratasys). Charpy unnotched 19.7 +/- 4.3 horizontal and 39 +/- 10 vertical (Prusament, ISO 179-1)[4][3]
Layer adhesion / Z tensileMPaNot documented28-37 at break (printed ZX, ASTM D638, Stratasys F900 and F3300) against 72 +/- 5 at yield printed vertical (ISO 527-1, Prusament on the Pro HT90 with a 0.6 mm nozzle and 90 °C chamber) — a fourfold spread driven by chamber temperature and bead size[4][3]
Brittleness1–5Not documentedBrittle — snaps with little warning; notched Charpy only 3.4 kJ/m²[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedShore D 83.5 (Prusa Polymers method); Rockwell M110 / R126 on extruded PEI stock (ASTM D785)[3][18]

Elasticity / flexibility1–5Not documentedRigid[3]
Z strength as % of XY%Not documented36-40 (Stratasys ZX against XZ tensile at break, ASTM D638) against 76 (Prusament vertical against horizontal tensile yield, ISO 527-1)[4][3]

Thermal expansion (CTE)µm/m·KNot documented36.1 (printed XY, -50 to 60 °C, ASTM E831), falling to 29.8 over 60-205 °C; ZX gives 32.5 over -50 to 110 °C and 16.2 over 110-165 °C[4]
Flammability / UL 94Not documentedUL 94 V-0 at 1.5 mm, rated on the base resin[2]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[19]Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[19]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[19]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[19]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[19]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[19]Ventilated room or enclosure recommended[19]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[20]Chlorinated hydrocarbons — dichloromethane and chloroform — are solvents for polyetherimide. Laboratory reagents.[21][22]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[20]Acetone, MEK, benzene, toluene and butyl acetate craze or stress-crack it; alcohols, fuels and dilute acids do not.[22][21]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[20]Dichloromethane is the only welding route, and it is a controlled carcinogen rather than a workshop material.[21][22]
