| Densityg/cm³ | 1.09 (ISO 1183)[1] | 1.06 (ISO 1183, 3DXTech iOn PA6 alloy)[4] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 47–167; the middle of the market is about 103[5][6][7] | 1 kg-equivalent spools span 39–136; the middle of the market is about 104, though budget unfilled PA6 has now arrived at 39[5][8] |
| Price range across brandsUSD/kg | 47–167 across brands; IEMAI 47, YXPOLYER 65, 3DXTech 140 at 750 g pricing; the EMI-shielding ABS grade runs 167[5][6][7] | 39–136 across brands; YXPOLYER 39, 3DXTech iOn Nylon 6 Alloy 104, WearX Nylon 6 136. Unfilled PA6 filament stays rare — most PA6 reaches the market glass- or carbon-filled[5][8] |

| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 220–260 (Polymaker); 225–265 (Simplify3D)[2][9] |
| Bed temperature°C | Not documented | 70–100 (Polymaker); 70–90 (Simplify3D)[2][9] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[10] | Enclosure required (passive)[11][2] |
| Part cooling fan | Not documented | Part cooling fan not required (Simplify3D)[9] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][12] | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[9][2] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[10] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[10] | Needs a specific surface plus adhesive[9][2] |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[13] | Moderate — retraction tuning needed[2] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[10] | Advanced — enclosure, hardware upgrades, tuning; the filament must be kept dry throughout the print[2][14] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Brass fine indefinitely for unfilled grades[2] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Non-abrasive when unfilled[2] |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[15] | Very high — frequent jams without careful setup; wet nylon pops and cracks in the melt[16][14] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[12] | Moderate — good heatbreak cooling needed[9] |
| Hotend requirement | No special hot-end required[12] | May require an all-metal hot end (Simplify3D)[9] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[17][18][15] | Very high (>2 %) — Polymaker groups nylon with PVA as the most moisture-prone class, and its own PA6-based composites reach 2.35–3.33 % equilibrium[14][19] |
| Drying temperature & time | Not documented | 100 °C for 8 h (Polymaker CoPA); storage below 20 % RH[11][20] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[14] | Popping and cracking during extrusion, then defects that Polymaker describes as very hard to diagnose[16] |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[14] | Measured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[11][16] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[14] | Sealed below 20 % RH with desiccant; Polymaker says nylon often needs to stay in a dryer while printing[20][14] |
| Hydrolysis at melt temperature | Not documented | Polymaker requires a 100 °C dry for 8 h and storage below 20 % RH; no molecular-weight loss figure is published, and the published wet data is conditioning rather than melt hydrolysis[11][20] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][21] | 62 at break (printed XY, ISO 527, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned to 20 °C / 50 % RH gives 67.6 ultimate and 49.3 at yield printed XZ (ASTM D638)[4][22] |
| Young's modulusMPa | 2130 (printed XY, ISO 527)[1] | 2110 (printed XY, ISO 527, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 2232 printed XZ and 1817 ZX (ASTM D638)[4][22] |
| Elongation at break% | 4 at break (printed XY, ISO 527)[1] | 9 at break (printed XY, ISO 527, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 38 printed XZ against 3.2 in ZX (ASTM D638)[4][22] |
| Flexural strengthMPa | 80 (printed XY, ISO 178)[1] | 78 (printed XY, ISO 178, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 97.2 printed XZ and 82 ZX (ASTM D790)[4][22] |
| Flexural modulusMPa | 2275 (printed XY, ISO 178)[1] | 2200 (printed XY, ISO 178, 3DXTech iOn PA6 alloy); Stratasys FDM Nylon 6 conditioned gives 2196 printed XZ and 1879 ZX (ASTM D790)[4][22] |
| Other impact data | Not documented | Izod notched 106 J/m printed XZ against 43 J/m in ZX; unnotched 2873 against 192 J/m (Stratasys FDM Nylon 6, conditioned 20 °C / 50 % RH, ASTM D256 Method A) — a 15x anisotropy unnotched[22] |
| Layer adhesion / Z tensileMPa | Not documented | 36.5 ultimate and 28.9 at yield printed ZX (Stratasys FDM Nylon 6, conditioned 20 °C / 50 % RH, ASTM D638)[22] |
| Brittleness1–5 | Moderate[1] | Tough — absorbs impact, yields before breaking[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Shore D 86 and Rockwell 85 (108) — the source does not name the scales on extruded unfilled PA66 stock (ASTM D2240, D785); no figure is published for a PA6 filament[23] |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1] | Moderate[2] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][21] | Excellent — living hinges viable[2] |
| Elasticity / flexibility1–5 | Rigid[1] | Semi-flexible[16] |
| Z strength as % of XY% | Not documented | 54 (Stratasys FDM Nylon 6 conditioned, ZX against XZ ultimate tensile, ASTM D638); 59 on the yield figures[22] |
| Wear resistance & friction | Not documented | 3DXTech sells a dedicated wear-resistant PA6 grade; abrasion resistance is the usual reason to choose PA6 over PA12[5] |
| Thermal Properties | ||
| HDT at 1.8 MPa°C | Not documented | 93 (Stratasys FDM Nylon 6, conditioned, ASTM D648 at 264 psi)[22] |
| Glass transition (Tg)°C | 105 (DSC)[1] | 105 (DSC, 3DXTech iOn PA6 alloy)[4] |
| Thermal expansion (CTE)µm/m·K | Not documented | 81.0 on extruded unfilled PA66 stock (ASTM D696; source states 4.5e-5 in/in/°F); no figure is published for a PA6 filament, and PA6 and PA66 expand almost identically[23] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published for the unfilled filament grades surveyed[4] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Months outdoors before embrittlement — unstabilised polyamide yellows and chalks under UV[2] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[24] | Withstands oils, fuels and alkalis — the usual reason to choose a polyamide[2] |
| Water / humidity resistance in service1–5 | Not documented | Absorbs water, properties shift — a conditioned part is measurably softer and larger than the same part dry[16][11] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[13] | Polymaker notes medical-grade variants exist, but standard filament is not food-contact certified[2] |
| Biodegradability / compostability | Not biodegradable[13] | Not biodegradable[2] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[13] | Mechanically recyclable but not accepted in household plastic collection[2] |
| Electrical & ESD properties | Surface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][21] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[3][10] | Moderate — measurable VOCs and UFPs, ventilation advised[3] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[3] | Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[3] |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[3] | ≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[3] |
| Hazardous species emitted | Styrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[3][10] | Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[3] |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[3][10] | Ventilated room or enclosure recommended[3] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[13] | Sands poorly — the toughness makes it gum rather than powder[9] |
| Painting & finishing | Paints readily after light abrasion[13] | Not documented |
| Gluing & solvent welding | Not documented | Cyanoacrylate; no common solvent welds polyamide[9] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing[9] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[25][10] | PVA dissolves cleanly against nylon; Polymaker sells a break-away PolySupport for PA12[9] |
| Dimensional accuracy & detail | Not documented | Parts grow as they absorb moisture after printing; Polymaker declines to publish a standard dimensional allowance because it depends on geometry and infill[16] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[26][24] | Dissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[27] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[26][28] | Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[27] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[29] | None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[27] |
