Identity & Market
Base polymer / chemistryCarbon-filled polyamide compounded to a static-dissipative resistivity — Polymaker's grade uses a PA612 matrix[1]PLA compounded with impact modifiers; suppliers publish the base as polylactic acid only[2][3]
Densityg/cm³1.10 (ISO 1183)[1]1.17–1.24 (Polymaker); 1.21 (Bambu Lab, ISO 1183)[2][3]
Typical priceUSD/kg1 kg-equivalent spools cluster near 130[4]Mainstream 1 kg spools cluster near 16[5][6]
Price range across brandsUSD/kg130 at Polymaker's 0.5 kg pricing[4]10–40 across brands; budget house brands 10–17, Sakata 3D HR-870 26, Polymaker and Fiberlogy 36–40[7][6][8][9][10]
Market availability1–5Special order, 1–2 makers worldwide[4]Stocked by most mainstream brands[7][5][6][8][9]
Spool sizes & diameters1.75 mm; 0.5 kg spools[4]1.75 and 2.85 mm; 0.75, 0.85, 1 and 1.1 kg spools[8][9][7]
Typical applicationsElectronics jigs and trays that also need nylon toughness and heat resistance[1]Functional parts and enclosures that need impact tolerance but not heat resistance[2][3]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[11]
Printing Parameters
Nozzle temperature°CNot documented190–230 (Polymaker); Bambu Lab Tough+ needs 220–250[2][3]
Bed temperature°CNot documented25–60 (Polymaker); 35–65 (Bambu Lab Tough+)[2][3]
Enclosure / chamber requirement1–5Enclosure required (passive)[12]Open frame is fine[2][3]
Part cooling fanNot documentedFan on[2][3]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[13][12]Textured or smooth PEI; Bambu Lab recommends glue stick or liquid glue for Tough+[2][3]
Warping tendency1–5Not documentedNone[2]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[13]Sticks to anything[14]
Stringing / oozing tendency1–5Moderate — retraction tuning needed[12]Slight — 1–3 mm retraction handles it[2][14]
Overall printing difficulty1–5Expert / industrial hardware only[12][15]Easy — minor profile tuning; Tough+ wants a hotter nozzle than plain PLA[2][3]
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]
Abrasiveness1–5Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[1]Non-abrasive[17][16]
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; softens below 60 °C like plain PLA[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]Low — 0.27 % saturated at 25 °C / 55 % RH[3]
Equilibrium moisture content at ~50 % RH%Not documented0.27 saturated at 25 °C / 55 % RH (Bambu Lab Tough+)[3]
Drying temperature & timeNot documented55 °C for 6–8 h; 65–75 °C for 12 h on a Bambu Lab X1 heatbed[2][3]
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 and publishes no dry-versus-conditioned figures for the modified grades; the loss shows as poor layer adhesion rather than a strength number[15]
Storage requirementSealed below 20 % RH with desiccant[15]Sealed with desiccant below 20 % RH; shelf life at ambient is long[3][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[21][22]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]35–43 (printed XY, ISO 527); 53 on My Tech Fun 4×4 mm bars for Bambu Lab Tough[2][3][23][24]
Young's modulusMPa4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[1]1860–2150 (printed XY, ISO 527) — below plain PLA at 2300–3427[2][3][25][26]
Elongation at break%3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[1]5.1–5.7 (printed XY, ISO 527)[2][3]
Flexural strengthMPaNot documented62–65 (printed XY, ISO 178) — below plain PLA at 76–87[2][3][27][26]
Flexural modulusMPaNot documented2140–2393 (printed XY, ISO 178)[2][3]
Charpy impact, notchedkJ/m²5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[1]38.9–72.3 (printed XY, ISO 179, notched) — 5–9× plain PLA[2][3]
Other impact dataCharpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[1]Charpy unnotched 80.6 printed XY (Bambu Lab Tough+); CNC Kitchen measured ~20 vs 5 kJ/m² for PolyLite PLA[3][23]
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]20.9–32.4 printed Z (ISO 527); 33.0 on My Tech Fun layer-adhesion bars vs 27.6 for PLA Basic[2][3][24]
Brittleness1–5Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[1]Tough — absorbs impact, yields before breaking[2][3][23]
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[28]78.8 Shore D measured on printed bars (My Tech Fun), against 75.3 for the same maker's plain PLA[29]
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[30][1]Poor — 12 mm bar sagged to 20.2 mm over 5 days at 1.25 kg, the same as plain PLA[24][31]
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[30]Below average — impact modifiers raise absorbed energy 5–9×; plain PLA ran 38 000–49 000 cycles at 30 % of tensile strength[32][3][23]
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Z strength as % of XY%26 (printed Z against XY tensile)[1]60 (Bambu Lab Tough+) to 78 (PolyMax PLA), printed[2][3]
Thermal Properties
HDT at 0.45 MPa°C157.0 (ISO 75, 0.45 MPa)[1]55 (PolyMax) to 61 (Tough+), ISO 75 at 0.45 MPa[2][3]
HDT at 1.8 MPa°C125.4 (ISO 75, 1.8 MPa)[1]52 (PolyMax) to 58 (Tough+), ISO 75 at 1.8 MPa[2][3]
Glass transition (Tg)°C41.8 (DSC)[1]61 (DSC)[2][3]
Melting point / Vicat°C187.3 melting (DSC); Vicat 190.0 (ISO 306)[1]149–151 peak melt (DSC); Vicat 62 (ISO 306)[2][3]
Continuous service temperature°CNot documented48–57 — loaded bars begin to move at this temperature: 48 for Polymaker PLA Pro, 50 for Sunlu PLA+, 52 for Bambu Lab Tough, 57 for PolyTerra PLA+[24][33][29][31]
Thermal expansion (CTE)µm/m·KNot documented96–99 for plain printed PLA (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[34]
Flammability / UL 94Flammable; no UL 94 rating published for the grades surveyed[21]Flammable; no UL 94 rating published by the major brands[3][2]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — unstabilised polyamide yellows under UV[12]Degrades within weeks outdoors[18][35]
Chemical resistanceWithstands oils, fuels and alkalis[12]Good against weak acids, oils and grease; poor against strong acids and alkalis[2][3]
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[36][18]
RecyclabilityNot accepted in household plastic collection[12]Mechanically recyclable; not accepted in household plastic collection[36]
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[37]Low hazard — minimal VOC and particle emission[37]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[37]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[37]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[37]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[37]None needed in a normal room[37]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[21]Not documented
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[13]Wet sanding — dry sanding heats the surface by friction and smears it[35][18]
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[13]Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[18][38]
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 documentedPolySupport and PolyDissolve S1 (Polymaker); Support for PLA (Bambu Lab)[2][3]
Dimensional accuracy & detailNot documented55° overhangs and 30 mm bridges (Bambu Lab Tough+)[3]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[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 byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack 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 agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[39]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[42][41]
